Updated: January 2019

For years, the United States and the international community have tried to negotiate an end to North Korea’s nuclear and missile development and its export of ballistic missile technology. Those efforts have been replete with periods of crisis, stalemate, and tentative progress towards denuclearization, and North Korea has long been a key challenge for the global nuclear nonproliferation regime.

Take Action

Americans are anxious about the growing risk of a nuclear war. Adopting a policy of “no first use” would reduce the chances of war from a miscalculation or misunderstanding.

A nuclear war can never be won, and must never be fought.

Take Action Here.

The United States has pursued a variety of policy responses to the proliferation challenges posed by North Korea, including military cooperation with U.S. allies in the region, wide-ranging sanctions, and non-proliferation mechanisms such as export controls. The United States also engaged in two major diplomatic initiatives to have North Korea abandon its nuclear weapons efforts in return for aid.

In 1994, faced with North Korea’s announced intent to withdraw from the nuclear Nonproliferation Treaty (NPT), which requires non-nuclear weapon states to forswear the development and acquisition of nuclear weapons, the United States and North Korea signed the Agreed Framework. Under this agreement, Pyongyang committed to freezing its illicit plutonium weapons program in exchange for aid.

Following the collapse of this agreement in 2002, North Korea claimed that it had withdrawn from the NPT in January 2003 and once again began operating its nuclear facilities.

The second major diplomatic effort were the Six-Party Talks initiated in August of 2003 which involved China, Japan, North Korea, Russia, South Korea, and the United States. In between periods of stalemate and crisis, those talks arrived at critical breakthroughs in 2005, when North Korea pledged to abandon “all nuclear weapons and existing nuclear programs” and return to the NPT, and in 2007, when the parties agreed on a series of steps to implement that 2005 agreement.

Those talks, however, broke down in 2009 following disagreements over verification and an internationally condemned North Korea rocket launch. Pyongyang has since stated that it would never return to the talks and is no longer bound by their agreements. The other five parties state that they remain committed to the talks, and have called for Pyongyang to recommit to its 2005 denuclearization pledge.

In January 2018, another diplomatic effort began when North Korean leader Kim Jong Un declared the country's nuclear arsenal "complete" and offered to discuss with Seoul North Korea's participation in the South Korean Olympics. North Korea's delegation to the Olympics included Kim Jong Un's sister, who met with South Korean President Moon Jae-in. That meeting led to a sustained inter-Korean dialouge, including a meeting between Kim Jong Un and Moon Jae-in April 27 that produced a declaration referencing the shared goal of denuclearization of the Korean peninsula.

During a high-level meeting with South Korean officials in Pyongyang in March, Kim Jong Un conveyed his interest in meeting with U.S. President Donald Trump. Trump accepted the offer and the two leaders will meet June 12 in Singapore. 

The following chronology summarizes in greater detail developments in North Korea’s nuclear and missile programs, and the efforts to end them, since 1985.


Skip to: 1985, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019

1985

December 12, 1985: North Korea accedes to the nuclear Nonproliferation Treaty (NPT) but does not complete a safeguards agreement with the International Atomic Energy Agency (IAEA). Under Article III of the NPT, North Korea has 18 months to conclude such an arrangement. In coming years, North Korea links adherence to this provision of the treaty to the withdrawal of U.S. nuclear weapons from South Korea.

1991

September 27, 1991: President George Bush announces the unilateral withdrawal of all naval and land-based tactical nuclear weapons deployed abroad. Approximately 100 U.S. nuclear weapons had been based in South Korea. Eight days later, Soviet President Mikhail Gorbachev reciprocates.

November 8, 1991: In response to President Bush’s unilateral move, President Roh Tae Woo of South Korea announces the Declaration on the Denuclearization of the Korean Peninsula, under which South Korea promises not to produce, possess, store, deploy, or use nuclear weapons. In addition, the declaration unilaterally prohibits South Korea from possessing nuclear reprocessing or uranium enrichment facilities. These promises, if enacted, would satisfy all of North Korea’s conditions for allowing IAEA inspections of its nuclear facilities.

1992

January 20, 1992: The two Koreas sign the South-North Joint Declaration on the Denuclearization of the Korean Peninsula. Under the declaration, both countries agree not to “test, manufacture, produce, receive, possess, store, deploy or use nuclear weapons” or to “possess nuclear reprocessing and uranium enrichment facilities.” They also agree to mutual inspections for verification.

January 30, 1992: More than six years after signing the NPT, North Korea concludes a comprehensive safeguards agreement with the IAEA.

March 6, 1992: The United States imposes sanctions on North Korea’s Lyongaksan Machineries and Equipment Export Corporation and Changgwang Sinyong Corporation for missile proliferation activities.*

April 9, 1992: North Korea ratifies the safeguards agreement with the IAEA.

May 4, 1992: North Korea submits its nuclear material declarations to the IAEA, declaring seven sites and some 90 grams of plutonium that could be subject to IAEA inspection. Pyongyang claims that the nuclear material was the result of reprocessing 89 defective fuel rods in 1989. The IAEA conducted inspections to verify the completeness of this declaration from mid-1992 to early 1993.

June 23, 1992: The United States imposes “missile sanctions” on the North Korean entities sanctioned in March.*

September 1992: IAEA inspectors discover discrepancies in North Korea’s “initial report” on its nuclear program and ask for clarification on several issues, including the amount of reprocessed plutonium in North Korea.

1993

February 9, 1993: The IAEA demands special inspections of two sites that are believed to store nuclear waste. The request is based on strong evidence that North Korea has been cheating on its commitments under the NPT. North Korea refuses the IAEA’s request.

March 12, 1993: Amid demands for special inspections, North Korea announces its intention to withdraw from the NPT in three months, citing Article X provisions that allow withdrawal for supreme national security considerations.

April 1, 1993: The IAEA declares that North Korea is not adhering to its safeguards agreement and that it cannot guarantee that North Korean nuclear material is not being diverted for nonpeaceful uses.

June 11, 1993: Following talks with the United States in New York, North Korea suspends its decision to pull out of the NPT just before the withdrawal would have become legally effective. North Korea also agrees to the full and impartial application of IAEA safeguards.

For its part, the United States grants assurances against the threat and use of force, including nuclear weapons. Washington also promises not to interfere with North Korea’s internal affairs.

July 19, 1993: After a second round of talks with the United States, North Korea announces in a joint statement that it is “prepared to begin consultations with the IAEA on outstanding safeguards and other issues” and that it is ready to negotiate IAEA inspections of its nuclear facilities. The joint statement also indicates that Pyongyang might consider a deal with the United States to replace its graphite nuclear reactors with light-water reactors (LWRs), which are proliferation resistant.

Late 1993: The Central Intelligence Agency (CIA) and the Defense Intelligence Agency estimate that North Korea had separated about 12 kilograms of plutonium. This amount is enough for at least one or two nuclear weapons.

1994

January 1994: The director of the CIA estimates that North Korea may have produced one or two nuclear weapons.

February 15, 1994: North Korea finalizes an agreement with the IAEA to allow inspections of all seven of its declared nuclear facilities, averting sanctions by the United Nations Security Council.

March 1, 1994: IAEA inspectors arrive in North Korea for the first inspections since 1993.

March 21, 1994: Responding to North Korea’s refusal to allow the inspection team to inspect a plutonium reprocessing plant at Yongbyon, the IAEA Board of Governors approves a resolution calling on North Korea to “immediately allow the IAEA to complete all requested inspection activities and to comply fully with its safeguards agreements.”

May 19, 1994: The IAEA confirms that North Korea has begun removing spent fuel from its 5-megawatt nuclear research reactor even though international monitors were not present. The United States and the IAEA had insisted that inspectors be present for any such action because spent fuel can potentially be reprocessed for use in nuclear weapons.

June 13, 1994: North Korea announces its withdrawal from the IAEA. This is distinct from pulling out of the NPT—North Korea is still required to undergo IAEA inspections as part of its NPT obligations. The IAEA contends that North Korea’s safeguards agreement remains in force. However, North Korea no longer participates in IAEA functions as a member state.

June 15, 1994: Former U.S. President Jimmy Carter negotiates a deal with North Korea in which Pyongyang confirms its willingness to “freeze” its nuclear weapons program and resume high-level talks with the United States. Bilateral talks are expected to begin, provided that North Korea allows the IAEA safeguards to remain in place, does not refuel its 5-megawatt nuclear reactor, and does not reprocess any spent nuclear fuel.

July 9, 1994: North Korean President Kim Il Sung dies and is succeeded by his son, Kim Jong Il.

August 12, 1994: An “agreed statement” is signed that establishes a three-stage process for the elimination of North Korea’s nuclear weapons program. In return, the United States promises to move toward normalized economic and diplomatic relations and assures North Korea that it will provide assistance with the construction of proliferation-resistant LWRs to replace North Korea’s graphite-moderated reactors.

October 21, 1994: The United States and North Korea conclude four months of negotiations by adopting the “Agreed Framework” in Geneva. To resolve U.S. concerns about Pyongyang’s plutonium-producing reactors and the Yongbyon reprocessing facility, the agreement calls for North Korea to freeze and eventually eliminate its nuclear facilities, a process that will require dismantling three nuclear reactors, two of which are still under construction. North Korea also allows the IAEA to verify compliance through “special inspections,” and it agrees to allow 8,000 spent nuclear reactor fuel elements to be removed to a third country.

In exchange, Pyongyang will receive two LWRs and annual shipments of heavy fuel oil during construction of the reactors. The LWRs will be financed and constructed through the Korean Peninsula Energy Development Organization (KEDO), a multinational consortium.

Calling for movement toward full normalization of political and economic relations, the accord also serves as a jumping-off point for U.S.-North Korean dialogue on Pyongyang’s development and export of ballistic missiles, as well as other issues of bilateral concern.

November 28, 1994: The IAEA announces that it had confirmed that construction has been halted at North Korea’s Nyongbyon and Taochon nuclear facilities and that these facilities are not operational.

1995

March 9, 1995:KEDO is formed in New York with the United States, South Korea, and Japan as the organization’s original members.

1996

January 1996: North Korea agrees in principle to a meeting on missile proliferation issues, which had been requested in a letter by Deputy Assistant Secretary of State for East Asian and Pacific Affairs Thomas Hubbard. However, Pyongyang contends that the United States would have to ease economic sanctions before it could agree on a date and venue for the talks.

In testimony before a House International Relations subcommittee on March 19, Assistant Secretary of State for East Asian and Pacific Affairs Winston Lord says that Washington is willing to ease economic sanctions if progress is made on the missile export issue.

April 21-22, 1996: The United States and North Korea meet in Berlin for their first round of bilateral missile talks. The United States reportedly suggests that North Korea should adhere to the Missile Technology Control Regime (MTCR), a voluntary international agreement aimed at controlling sales of ballistic missile systems, components, and technology. North Korea allegedly demands that the United States provide compensation for lost missile-related revenue.

May 24, 1996: The United States imposes sanctions on North Korea and Iran for missile technology-related transfers. The sanctions prohibit any imports or exports to sanctioned firms and to those sectors of the North Korean economy that are considered missile-related. The pre-existing general ban on trade with both countries makes the sanctions largely symbolic.*

October 16, 1996: After detecting North Korean preparations for a test of its medium-range Nodong missile, the United States deploys a reconnaissance ship and aircraft to Japan. Following several meetings in New York between U.S. and North Korean diplomats, the State Department confirms on November 8 that the missile test has been canceled.

1997

June 11-13, 1997: The second round of U.S.-North Korean missile talks takes place in New York, with U.S. negotiators pressing North Korea not to deploy the Nodong missile and to end sales of Scud missiles and their components. The parties reach no agreement but reportedly lay the foundation for future talks.

August 6, 1997: The United States imposes new sanctions on two additional North Korean entities for unspecified missile-proliferation activities.*

1998

February 25, 1998: At his inaugural speech, South Korean President Kim Dae-jung announces his “sunshine policy,” which strives to improve inter-Korean relations through peace, reconciliation, and cooperation.

April 17, 1998: The United States imposes sanctions on North Korea and Pakistan in response to Pyongyang’s transfer of missile technology and components to Pakistan’s Khan Research Laboratory.*

June 16, 1998: The official Korean Central News Agency reports that Pyongyang will only end its missile technology exports if it is suitably compensated for financial losses.

July 15, 1998: The bipartisan Rumsfeld Commission concludes that the United States may have “little or no warning” before facing a long-range ballistic missile threat from “rogue states,” such as North Korea and Iran.

August 31, 1998: North Korea launches a three-stage Taepo Dong-1 rocket with a range of 1,500-2,000 kilometers that flies over Japan. Pyongyang announces that the rocket successfully placed a small satellite into orbit, a claim contested by U.S. Space Command. Japan suspends signature of a cost-sharing agreement for the Agreed Framework’s LWR project until November 1998. The U.S. intelligence community admits to being surprised by North Korea’s advances in missile-staging technology and its use of a solid-rocket motor for the missile’s third stage.

October 1, 1998: The third round of U.S.-North Korean missile talks begins in New York but makes little progress. The United States repeats its request for Pyongyang to terminate its missile programs in exchange for relief from economic sanctions. North Korea rejects the U.S. proposal on the grounds that the lifting of sanctions is implicit in the 1994 Agreed Framework.

November 12, 1998: President Bill Clinton appoints former Secretary of Defense William Perry to serve as North Korea policy coordinator—a post established by the 1999 Defense Authorization Act. Perry immediately undertakes an interagency review of U.S. policy toward North Korea and begins consultations with South Korea and Japan aimed at forming a unified approach to dealing with Pyongyang.

December 4-11, 1998: The United States and North Korea hold talks to address U.S. concerns about a suspected underground nuclear facility at Kumchang-ni. Pyongyang reportedly accepts in principle the idea of a U.S. inspection of the site but is unable to agree with U.S. proposals for “appropriate compensation.”

1999

February 2, 1999: CIA Director George Tenet testifies before the Senate Armed Services Committee that, with some technical improvements, North Korea would be able to use the Taepo Dong-1 to deliver small payloads to parts of Alaska and Hawaii. Tenet also says that Pyongyang’s Taepo Dong-2, if it had a third stage like the Taepo Dong-1, would be able to deliver large payloads to the continental United States, albeit with poor accuracy.

March 29-31, 1999: U.S. and North Korean officials hold a fourth round of missile talks in Pyongyang. The United States again expresses concern over North Korea’s missile development and proliferation activities and proposes a deal exchanging North Korean restraint for U.S. sanctions relief. U.S. officials describe the talks as “serious and intensive” but succeed only in reaching agreement to meet again at an unspecified date.

April 25, 1999: The United States, South Korea, and Japan establish the Trilateral Coordination and Oversight Group to institutionalize close consultation and policy coordination in dealing with North Korea.

May 20-24, 1999: A U.S. inspection team visits the North Korean suspected nuclear site in Kumchang-ni. According to the State Department, the team finds no evidence of nuclear activity or violation of the Agreed Framework.

May 25-28, 1999: Traveling to Pyongyang as a presidential envoy, Perry meets with senior North Korean political, diplomatic, and military officials to discuss a major expansion in bilateral relations if Pyongyang is willing to address U.S. security concerns. Perry delivers a letter from President Clinton to North Korean leader Kim Jong Il, but the two do not meet. Perry reportedly calls on North Korea to satisfy U.S. concerns about ongoing nuclear weapons-related activities that are beyond the scope of the Agreed Framework and about ballistic missile development and proliferation in exchange for the lifting of U.S. sanctions, normalization of diplomatic relations, and potentially some form of security guarantee.

September 7-12, 1999: During talks in Berlin, North Korea agrees to a moratorium on testing any long-range missiles for the duration of talks with the United States. The United States agrees to a partial lifting of economic sanctions on North Korea. The two parties agree to continue high-level discussions. (Sanctions are not actually lifted until June 2000.)

September 9, 1999: A U.S. National Intelligence Estimate reports that North Korea will “most likely” develop an ICBM capable of delivering a 200-kilogram warhead to the U.S. mainland by 2015.

September 15, 1999: North Korean policy coordinator Perry submits his review of U.S. policy toward North Korea to Congress and releases an unclassified version of the report on October 12. The report recommends “a new, comprehensive and integrated approach to…negotiations with the [Democratic People’s Republic of Korea] DPRK,” which would involve a coordinated reduction in isolation by the United States and its allies in a “step-by-step and reciprocal fashion.” Potential engagement mechanisms could include the normalization of diplomatic relations and the relaxation of trade sanctions.

November 19, 1999: The United States and North Korea meet in Berlin for talks on bilateral relations and preparations for a North Korean high-level visit to the United States.

December 15, 1999: Five years after the Agreed Framework was signed, KEDO officials sign a turn-key contract with the Korea Electric Power Corporation to begin construction on the two LWRs in Kumho, North Korea. KEDO officials attribute the delay in signing the contract to complex legal and financial challenges and the tense political climate generated by the North Korean Taepo Dong-1 test in August 1998.

2000

April 6, 2000: The United States imposes sanctions on a North Korean firm, Changgwang Sinyong Corporation, for proliferating MTCR Category I items, possibly to Iran. Category I items include complete missile systems with ranges exceeding 300 kilometers and payloads over 500 kilograms, major subsystems, rocket stages or guidance systems, production facilities for MTCR-class missiles, or technology associated with such missiles.*

May 25-27, 2000: The United States conducts its second inspection of the Kumchang-ni site. The inspection team found that conditions had not changed since the first inspection in May 1999.

June 15, 2000: Following a historic summit, North and South Korea sign a joint declaration stating they have “agreed to resolve” the question of reunification of the Korean Peninsula. The agreement includes promises to reunite families divided by the Korean War and to pursue other economic and cultural exchanges. No commitments are made regarding nuclear weapons or missile programs or military deployments in the Demilitarized Zone.

June 19, 2000: Apparently encouraged by the North-South summit, the United States relaxes sanctions on North Korea, allowing a “wide range” of trade in commercial and consumer goods, easing restrictions on investment, and eliminating prohibitions on direct personal and commercial financial transactions. Sanctions related to terrorism and missile proliferation remain in place. The next day, North Korea reaffirms its moratorium on missile tests.

July 12, 2000: The fifth round of U.S.-North Korean missile talks in Kuala Lumpur end without resolution. During the meeting, North Korea repeats its demand for compensation, stated as $1 billion per year, in return for halting missile exports. The United States rejects this proposal but says that it is willing to move toward “economic normalization” in return for addressing U.S. concerns.

July 19, 2000: During a meeting with Russian President Vladimir Putin, Kim Jong Il reportedly promises to end his country’s missile program in exchange for assistance with satellite launches from countries that have expressed concern about North Korea’s missile program.

July 28, 2000: At the Association of Southeast Asian Nations Regional Forum in Bangkok, Thailand, Secretary of State Madeleine Albright engages in a “substantively modest” meeting with North Korean Foreign Minister Paek Nam Sun, the highest level of exchange to date. Paek gives no additional details about North Korea’s purported offer to end its missile program in return for space-launch assistance.

August 13, 2000: Kim Jong Il tells a meeting of 46 South Korean media executives in Pyongyang that his missile proposal was meant “in humor, while talking about science and state-of-the-art technologies,” according to the Korea Times. The report of the event is widely interpreted as undercutting the seriousness of Kim’s offer; however, English-language excerpts of Kim’s speech seem to confirm the offer: “I told…Putin that we would stop developing rockets when the United States comes forward and launches our satellites.”

August 28, 2000: U.S. Ambassador Wendy Sherman travels to Moscow to confirm the details of Kim Jong Il’s apparent missile proposal with her Russian counterparts. At a September 8 briefing, a senior State Department official says the United States is taking the North Korean offer “very seriously.”

September 27, 2000: U.S.-North Korean talks resume in New York on nuclear issues, missiles, and terrorism. The two countries issue a joint statement on terrorism, a move that indicates progress toward removing North Korea from the State Department’s terrorism list.

October 9-12, 2000: Kim Jong Il’s second-in-command, Vice Marshal Jo Myong Rok, visits Washington as a special envoy. He delivers a letter to President Clinton and meets with the secretaries of state and defense. The move is seen as an affirmation of Kim’s commitment to improving U.S.-North Korean ties.

October 12, 2000: The United States and North Korea issue a joint statement noting that resolution of the missile issue would “make an essential contribution to fundamentally improved relations” and reiterating the two countries’ commitment to implementation of the Agreed Framework. The statement also says that Albright will visit North Korea in the near future to prepare for a possible visit by President Clinton.

October 24, 2000: Secretary Albright concludes a two-day visit to Pyongyang to meet with Kim Jong Il. During the visit, Kim says that North Korea would not further test the Taepo Dong-1 missile. In addition to discussing Pyongyang’s indigenous missile program, the talks cover North Korean missile technology exports, nuclear transparency, the normalization of relations, and a possible trip by President Clinton to Pyongyang.

November 1-3, 2000: A seventh round of missile talks between Pyongyang and Washington ends without an agreement in Kuala Lumpur, Malaysia. The failure to build upon the momentum derived from Secretary Albright's recent meeting with Kim Jong-Il diminished hopes of a presidential trip to North Korea before the end of President Clinton's term.

December 28, 2000: President Clinton announces that he will not travel to North Korea before the end of his term, citing "insufficient time to complete the work at hand." According to a March 6 New York Times article, Clinton's national security adviser Sandy Berger was hesitant to have the president leave the country during the presidential election dispute, which he deemed "a potential 'constitutional crisis.'"

2001

January 2, 2001: The United States imposes sanctions on North Korea’s Changgwang Sinyong Corporation for violation of the Iran Nonproliferation Act of 2000.*

March 6, 2001: At a joint press briefing with the Swedish foreign minister, Secretary of State Colin Powell says that the administration “plan[s] to engage with North Korea to pick up where President Clinton left off. Some promising elements were left on the table and we will be examining those elements.”

March 7, 2001: In a New York Times op-ed, Wendy Sherman, former special adviser to the president and secretary of state for North Korea policy, writes that a deal with North Korea to eliminate its medium- and long-range missiles and end its missile exports had been “tantalizingly close” at the end of the Clinton administration.

After a working meeting with South Korean President Kim Dae-jung at the White House, President George W. Bush tells reporters that he “look[s] forward to, at some point in the future, having a dialogue with the North Koreans, but that any negotiation would require complete verification of the terms of a potential agreement.” According to Clinton administration officials, the issue of how to verify a missile deal remained one of the final stumbling blocks to a successful arrangement. Bush also questions whether Pyongyang is “keeping all terms of all agreements.”

Just prior to Bush’s comments, Powell amended his remarks from the previous day, noting that if “there was some suggestion that imminent negotiations are about to begin—that is not the case.”

March 13, 2001: North Korea, apparently reacting to Washington’s new tone, cancels ministerial-level talks with Seoul. The talks were intended to promote further political reconciliation.

March 15, 2001: Pyongyang threatens to “take thousand-fold revenge” on the United States “and its black-hearted intention to torpedo the dialogue between north and south [Korea].” The statement, issued by the Korean Central News Agency, called Washington’s new policies “hostile” and noted that Pyongyang remains “fully prepared for both dialogue and war.”

May 3, 2001: At a press conference in Pyongyang, a European Union delegation headed by Swedish Prime Minister Göran Persson reports that Kim Jong Il pledged that he will extend Pyongyang’s moratorium on missile testing until 2003 and that Kim was “committed” to a second inter-Korean summit.

June 6, 2001: In a press release, President Bush announces the completion of his administration’s North Korea policy review and its determination that “serious discussions” on a “broad agenda” should be resumed with Pyongyang. Bush states his desire to conduct “comprehensive” negotiations, including “improved implementation of the Agreed Framework,” “verifiable constraints” on North Korea’s missile programs, a ban on North Korea’s missile exports, and “a less threatening conventional military posture.”

June 13, 2001: U.S. Special Envoy Jack Pritchard meets in New York with the North Korean representative to the UN, Hyong-ch’ol Yi, to make arrangements for bilateral talks.

June 26, 2001: The State Department announces sanctions under the Iran Nonproliferation Act of 2000 on North Korea’s Changgwang Sinyong Corporation, for unspecified missile-related transfers to Iran. The announcement represents the second time that sanctions had been imposed under the act, the first also being on Changgwang Sinyong on January 2.

The sanctions prohibit any U.S. entity from doing business with the North Korean firm, which has been punished several times previously under more general missile transfer sanctions. However, the sanctions are largely symbolic, as Changgwang Sinyong is still subject to the active sanctions imposed on January 2, 2001, and missile sanctions that were imposed on April 6, 2000.*

July 6, 2001: Deputy Secretary of State Richard Armitage confirms that North Korea tested a rocket “motor engine” in late June, but that there was “nothing in itself wrong with that,” nor did the administration consider the test to have violated Pyongyang’s testing moratorium.

August 4, 2001: During a meeting in Moscow with President Putin, Kim Jong Il reaffirms his pledge to maintain a moratorium on ballistic missile flight-tests until 2003.

2002

January 29, 2002: In his State of the Union address, President Bush criticized North Korea for “arming with missiles and weapons of mass destruction, while starving its citizens.” Bush characterized North Korea, along with Iraq and Iran, as constituting an “axis of evil, arming to threaten the peace of the world.”

February 5, 2002: At a Senate Foreign Relations Committee hearing, Powell reiterates the administration's policy that it is willing to resume a dialogue with North Korea at "any time, any place, or anywhere without any preconditions." Powell also confirms that the administration believes that Pyongyang continues to "comply with the [missile flight-test] moratorium they placed upon themselves and stay within the KEDO agreement," which is also known as the Agreed Framework.

March 15, 2002: Following reports that the U.S. nuclear posture review discusses the use of nuclear weapons against North Korea, Pyongyang's state-run press organ announces that, if the United States "tries to use nuclear weapons" against North Korea, it will be compelled to "examine all the agreements" reached with the United States. The report says that, "if the U.S. inflicts nuclear holocaust upon [North Korea], the former's mainland will not be safe either."

April 1, 2002: President Bush issues a memorandum stating that he will not certify North Korea's compliance with the Agreed Framework. However, for national security considerations, Bush waives applicable U.S. law prohibiting Washington from funding KEDO, allowing the United States to continue financially supporting the Agreed Framework.

July 2, 2002: The United States cancels a planned delegation visit to North Korea, citing Pyongyang’s failure to respond to a proposed July 10 meeting date, as well as a June 29 naval skirmish between North and South Korea.

July 31, 2002: Powell meets briefly with Foreign Minister Paek Nam Sun during the Association of Southeast Asian Nations Regional Forum meeting in Brunei, generating speculation that a U.S. envoy will visit North Korea. It is the highest-level exchange between the two countries since the Bush administration took office.

August 7, 2002: KEDO holds a ceremony to mark the pouring of the concrete foundation for the first LWR that the United States agreed to provide North Korea under the Agreed Framework. Jack Pritchard, the U.S. representative to KEDO and State Department special envoy for negotiations with North Korea, attends the ceremony. Pritchard is the most senior U.S. official to visit North Korea since former Secretary of State Albright in October 2000.

The United States urges North Korea to comply with IAEA safeguarding procedures for all its nuclear facilities as soon as possible, but Pyongyang states that it will not do so for at least three years, the Japanese newspaper Nihon Keizai Shimbun reports August 8. A North Korean Foreign Ministry spokesman also states that delays in completing the reactor project might motivate Pyongyang to pull out of the agreement.

August 16, 2002: The United States imposes sanctions on Changgwang Sinyong Corporation of North Korea and on the North Korean government itself for transferring missile technology to Yemen. White House Press Secretary Ari Fleischer states August 23 that the sanctions were a “pro forma requirement under the law for the State Department” and that Washington remains willing to “talk with North Korea any time, any place.”

August 31, 2002: Responding to an August 29 speech by Undersecretary of State for Arms Control and International Security John Bolton, North Korea says that “if the U.S. has a will to drop its hostile policy toward the DPRK it will have dialogue…the ball is in the court of the U.S. side.” Bolton had criticized Pyongyang’s missile, nuclear, and biological weapons programs.

September 17, 2002: North Korea announces that it will indefinitely extend its moratorium on missile testing as part of the North Korea-Japan Pyongyang Declaration signed during a meeting between Japanese Prime Minister Junichiro Koizumi and North Korean leader Kim Jong Il.

A portion of the North Korea-Japan declaration references nuclear weapons, saying that the two countries “affirmed the pledge to observe all the international agreements for a comprehensive solution to the nuclear issue on the Korean Peninsula.” It is unclear whether this statement simply affirms a commitment to existing agreements or signals support for additional arms control measures.

October 3-5, 2002: James Kelly, assistant secretary of state for East Asian and Pacific affairs, visits North Korea. The highest-ranking administration official to visit Pyongyang, Kelly reiterates U.S. concerns about North Korea’s nuclear and missile programs, export of missile components, conventional force posture, human rights violations, and humanitarian situation. Kelly informs North Korea that it could improve bilateral relations through a “comprehensive settlement” addressing these issues. No future meetings are announced.

Referring to Kelly’s approach as “high handed and arrogant,” North Korea argues that the U.S. policy “compels the DPRK to take all necessary countermeasures, pursuant to the army-based policy whose validity has been proven.”

October 16, 2002: The United States announces that North Korea admitted to having a clandestine program to enrich uranium for nuclear weapons after James Kelly, assistant secretary of state for East Asian and Pacific affairs, confronted representatives from Pyongyang during an October 3-5 visit. Kelly later explained that the North Korean admission came the day after he informed them that the United States was aware of the program. North Korea has denied several times that it admitted to having this program.

State Department spokesman Richard Boucher states that "North Korea's secret nuclear weapons program is a serious violation of North Korea's commitments under the Agreed Framework as well as under the nuclear Nonproliferation Treaty, its International Atomic Energy Agency safeguards agreement, and the Joint North-South Declaration on the Denuclearization of the Korean Peninsula."
Boucher also says that the United States wants North Korea to comply with its nonproliferation commitments and seeks "a peaceful resolution of this situation."

November 5, 2002: North Korea threatens to end its moratorium on ballistic missile tests if North Korea-Japan normalization talks do not achieve progress.

November 14, 2002: KEDO announces that it is suspending heavy-fuel oil deliveries to North Korea in response to Pyongyang's October 4 acknowledgment that it has a uranium-enrichment program. The last shipment reached North Korea November 18.

November 29, 2002: The IAEA adopts a resolution calling upon North Korea to "clarify" its "reported uranium-enrichment program." North Korea rejects the resolution, saying the IAEA's position is biased in favor of the United States.

December 9, 2002: Spanish and U.S. forces intercept and search a ship carrying a shipment of North Korean Scud missiles and related cargo to Yemen. The United States allows the shipment to be delivered because it lacks the necessary legal authority to seize the cargo. White House Press Secretary Ari Fleischer says that Washington had intelligence that the ship was carrying missiles to the Middle East and was concerned that its ultimate destination might have been Iraq.

December 12, 2002: North Korea sends a letter to the IAEA announcing that it is restarting its one functional reactor and is reopening the other nuclear facilities frozen under the Agreed Framework. The letter requests that the IAEA remove the seals and monitoring equipment from its nuclear facilities. A North Korean spokesman blames the United States for violating the Agreed Framework and says that the purpose of restarting the reactor is to generate electricity-an assertion disputed by U.S. officials.

A November 27 Congressional Research Service report states that the reactor could annually produce enough plutonium for one bomb. The CIA states in a 2002 report to Congress that the spent-fuel rods "contain enough plutonium for several more [nuclear] weapons."

U.S. estimates on North Korea's current nuclear status differ. A State Department official said January 3, 2003 that the U.S. intelligence community believes North Korea already possesses one or two nuclear weapons made from plutonium produced before the negotiation of the Agreed Framework. The CIA publicly estimates that Pyongyang "has produced enough plutonium" for one or two weapons.

December 14, 2002: North Korea states in a letter to the IAEA that the status of its nuclear facilities is a matter between the United States and North Korea and "not pursuant to any agreement" with the IAEA. The letter further declares that North Korea will take unilateral action to remove seals and monitoring cameras if the IAEA does not act.

December 22-24, 2002: North Korea cuts all seals and disrupts IAEA surveillance equipment on its nuclear facilities and materials. An IAEA spokesman says December 26 that North Korea started moving fresh fuel rods into the reactor, suggesting that it might be restarted soon.

December 27, 2002: North Korea orders IAEA inspectors out of the country. They leave on December 31.

2003

January 6, 2003: The IAEA Board of Governors adopts a resolution condemning North Korea's decision to restart its nuclear reactor and resume operation of its related facilities. The resolution "deplores" North Korea's action "in the strongest terms" and calls on Pyongyang to meet "immediately, as a first step" with IAEA officials. It also calls on North Korea to re-establish the seals and monitoring equipment it dismantled, comply fully with agency safeguards, clarify details about its reported uranium-enrichment program, and allow the agency to verify that all North Korea’s nuclear material is "declared and…subject to safeguards."

January 10, 2003: North Korea announces its withdrawal from the nuclear Nonproliferation Treaty (NPT), effective January 11. Although Article X of the NPT requires that a country give three months’ notice in advance of withdrawing, North Korea argues that it has satisfied that requirement because it originally announced its decision to withdraw March 12, 1993, and suspended the decision one day before it was to become legally binding.

January 12, 2003: Choe Jin Su, North Korea’s ambassador to China, signals that Pyongyang might not adhere to its moratorium on testing long-range missiles, saying that Pyongyang believes it “cannot go along with the self-imposed missile moratorium any longer,” according to a January 12 Los Angeles Times article.

February 12, 2003: Responding to North Korea’s rejection of the November 2002 and January 2003 IAEA resolutions, the IAEA Board of Governors adopts a resolution declaring Pyongyang in “further non-compliance” with its obligations under the NPT. The board decides to report the matter to the UN Security Council, in accordance with agency mandates.

February 27, 2003: U.S. officials confirm North Korea has restarted the five-megawatt nuclear reactor that had been frozen by the Agreed Framework.

March 19, 2003: North Korea again signals that it might not adhere to its moratorium on testing long-range missiles, asserting in a March 19 KCNA statement that it has the “sovereign right” to have a “peaceful” missile program. North Korea conducted missile tests February 24 and March 10, but both tests involved short-range missiles that did not violate the moratorium.

March 24, 2003: The United States imposes sanctions on the Changgwang Sinyong Corporation of North Korea for transferring missile technology to Khan Research Laboratories in Pakistan. The laboratory was sanctioned for receiving the items. Philip Reeker, deputy State Department spokesman, said April 1 that the sanctions were imposed only for a “missile-related transfer” and not the transfer of nuclear technology from Pakistan to North Korea.

April 23-25, 2003: The United States, North Korea, and China hold trilateral talks in Beijing. North Korea tells the U.S. delegation that it possesses nuclear weapons, according to Boucher on April 28. This constitutes the first time that Pyongyang has made such an admission.

North Korea also tells the U.S. delegation that it has completed reprocessing the spent nuclear fuel from the five-megawatt reactor frozen under the Agreed Framework, according to Secretary of State Colin Powell during an April 30 hearing before the Senate Appropriations Committee.

Boucher adds that the North Korean delegation told the U.S. officials that Pyongyang “might get rid of all their nuclear programs…[and] stop their missile exports.” Powell states April 28 that North Korea expects “something considerable in return” for this effort.

May 12, 2003
North Korea accuses the United States of violating the spirit of the 1992 Joint North-South Declaration on the Denuclearization of the Korean Peninsula, calling the agreement a “dead document” in a KCNA statement.

July 15, 2003
State Department spokesman Richard Boucher tells reporters that North Korean officials at their UN mission in New York have told U.S. officials that North Korea has completed reprocessing the 8,000 spent fuel rods from its Yongbyon reactor.

August 27-29, 2003
The first round of six-party talks is held in Beijing. The talks achieve no significant breakthroughs.

North Korea proposes a step-by-step solution, calling for the United States to conclude a “non-aggression treaty,” normalize bilateral diplomatic relations, refrain from hindering North Korea’s “economic cooperation” with other countries, complete the reactors promised under the Agreed Framework, resume suspended fuel oil shipments, and increase food aid. Pyongyang states that, in return, it will dismantle its “nuclear facility,” as well as end missile testing and export of missiles and related components. North Korea issues an explicit denial for the first time that it has a uranium-enrichment program.

The North Korean delegation, however, also threatens to test nuclear weapons or “demonstrate the means that they would have to deliver” them, according to a senior State Department official.

September 14, 2003: President George W. Bush agrees to waive the restrictions on U.S. funding to KEDO but only pledges to provide $3.72 million solely for administrative expenses. The United States does not provide any further funding for KEDO after 2003.


October 2, 2003
KCNA reports a statement from a North Korean Foreign Ministry official indicating that North Korea completed reprocessing its 8,000 spent fuel rods and “made a switchover in the use” of the spent fuel “in the direction increasing [sic] its nuclear deterrent force.” The official also states that Pyongyang will continue to produce and reprocess additional spent fuel when deemed necessary.

October 16, 2003
A statement from a North Korean Foreign Ministry official reported by KCNA suggests that Pyongyang may test nuclear weapons, stating that it will “take a measure to open its nuclear deterrent to the public as a physical force” if the United States refuses to change its negotiating stance.

October 19, 2003
President George W. Bush states during a trip to Asia that the United States is willing to provide a written, multilateral guarantee that the United States will not attack North Korea, but makes it clear that a formal nonaggression pact is “off the table.” Powell made a similar statement August 1.

November 6, 2003: North Korean ambassador to the United Kingdom, Ri Yong Ho, tells Reuters that North Korea possesses a workable nuclear device.

November 21, 2003
The KEDO Executive Board announces that it will suspend construction of two light-water nuclear reactors for one year beginning December 1. The Board adds that the project’s future “will be assessed and decided by the Executive Board before the expiration of the suspension period.” Department of State spokesperson Adam Ereli said November 5, however, that Bush administration believes there is “no future for the project.”

2004

January 8, 2004
North Korea allows an unofficial U.S. delegation to visit its nuclear facilities at Yongbyon and displays what it calls its “nuclear deterrent.” North Korean officials allow delegation member Siegfried Hecker—a senior fellow at the Los Alamos National Laboratory—to handle a jar containing what appears to be plutonium metal. North Korean officials claim that it came from reprocessing the spent fuel rods from its five-megawatt reactor.

The delegation also visits the spent fuel cooling pond that had been monitored under the Agreed Framework and observes that the rods have been removed. The North Korean officials tell the delegation that Pyongyang reprocessed all of the spent fuel rods between January and June 2003.

Hecker later tells the Senate Foreign Relations Committee that he does not know for certain that the substance was plutonium and that he could not determine when it was produced.

February 25-28, 2004
A second round of six-party talks takes place in Beijing. Little progress is made, although both sides agree to hold another round of talks before the end of June 2004, as well as a working group meeting to be held beforehand.

South Korea’s deputy foreign minister, Lee Soo-hyuck, issues a proposal—which China and Russia both support—to provide energy assistance to the North in return for a freeze of its nuclear program, along with a promise to dismantle it.

Wang Yi, China’s envoy to the six-party talks, states afterwards that “sharp” differences remain between Washington and Pyongyang. According to the Japanese Foreign Ministry, two specific issues divide North Korea and other participants. The first is that the United States, Japan, and South Korea want all of North Korea’s nuclear programs to be dismantled, but North Korea wishes to be allowed to retain one for “peaceful purposes.” The second is that Washington and the other two governments want Pyongyang to acknowledge that it has a uranium-enrichment program.

June 23-26, 2004: A third round of six-party talks is held in Beijing. The United States presents a detailed proposal for resolving the crisis.

The proposal calls for a two-phase process in which North Korea would receive fuel oil from China, South Korea, and Russia after agreeing to first freeze, then dismantle its nuclear programs. The United States and the other parties to the talks would also draft a multilateral security agreement and begin surveying North Korea’s energy needs. Additionally, Washington would begin bilateral discussions with Pyongyang on the removal of U.S. sanctions. The benefits spelled out in the proposal could be withdrawn if North Korea did not comply.

According to a June 28 North Korean Foreign Ministry statement, North Korea counters by proposing to “refrain from” producing, testing, or transferring nuclear weapons and to freeze “all the facilities related to nuclear weapons and products churned out by their operation.” According to the Foreign Ministry, the length of the freeze depends on “whether reward is made or not.”

November 26, 2004: The KEDO Executive Board announces that it will extend its suspension of the light-water reactor project for another year, beginning December 1.

2005

February 2, 2005: The New York Times and The Washington Post report that Libya received uranium hexafluoride suspected to be of North Korean origin in 2004. Several knowledgeable U.S. and other diplomatic sources later tell Arms Control Today that the evidence indicates, but does not prove, that the material originated in North Korea.

February 10, 2005: North Korea’s Foreign Ministry announces that Pyongyang has “produced nuclear weapons.” This was Pyongyang’s most definitive public claim to date at the time

 

on the status of its nuclear arsenal.

February 21, 2005: Seoul’s semi-official Yonhap News Agency reports that South Korea’s defense minister, Yoon Kwang-ung, tells a National Assembly Committee that North Korea has reprocessed “only part” of the 8,000 spent fuel rods from the Yongbyon reactor.

March 2, 2005: North Korea’s Foreign Ministry states that Pyongyang is no longer bound by its more than five-year-old moratorium on flight-testing longer-range missiles. Pyongyang, however, does not say it will resume such testing.

Early April, 2005: The United States sends an urgent diplomatic message to allies notifying them of U.S. concerns that North Korea might conduct a nuclear test.

April 9, 2005: North Korea expert Selig Harrison tells reporters that, during a recent meeting, North Korean Vice Foreign Minister Kim Gye Gwan said Pyongyang might give nuclear weapons to terrorists if “the United States drives us into a corner.”

May 11, 2005: North Korea’s Foreign Ministry announces that it has “successfully finished the unloading of 8,000 spent fuel rods” from its Yongbyon reactor. South Korea has verified the reactor shutdown “through various channels,” Foreign Affairs and Trade Ministry official Kim Sook tells the Korean Broadcasting System the same day.

June 2005: Pyongyang refuels its reactor at Yongbyon and begins reprocessing the 8,000 spent fuel rods removed in March, North Korean officials later tell Hecker.

June 29, 2005: The U.S. Treasury Department announces that the United States has frozen the U.S. assets of three North Korean entities “responsible for WMD and missile programs,” as well as barred U.S. citizens and companies from doing business with those entities. Those measures are taken pursuant to Executive Order 13382 issued that day by President George W. Bush.

July 9, 2005: After a meeting between U.S. Assistant Secretary of State for East Asian and Pacific Affairs Christopher Hill and North Korean Vice Foreign Minister Kim Gye Gwan, North Korea announces its return to the six-party talks. According to a KCNA statement, the “U.S. side clarified its official stand to recognize [North Korea] as a sovereign state, not to invade it and hold bilateral talks within the framework of the six-party talks.”

July 13, 2005: During a meeting with an envoy of Chinese President Hu Jintao, North Korean Leader Kim Jong Il reiterates his father’s [Kim Il Sung] apparent dying wish for the denuclearization of the Korean Peninsula, according to KCNA.

July 26, 2005: A new round of six-party talks begins in Beijing. The talks include an unprecedented number of U.S.-North Korean bilateral talks. While North Korea continued to deny that it has a “uranium-based nuclear weapons program,” Pyongyang suggested that it would “clarify” any relevant “credible information or evidence” presented by the United States in that regard.

The participants agree August 7 to recess for several weeks. The talks resume September 13.

September 15, 2005: The Department of the Treasury designates a Macau bank, Banco Delta Asia, as a “primary money laundering concern” under Section 311 of the USA PATRIOT Act, freezing about $25 million in North Korean funds. A department press release states that the bank has provided services to North Korean “government agencies and front companies,” adding that “[e]vidence exists that some of these agencies and front companies are engaged in illicit activities,” such as drug trafficking. The bank also has also circulated North Korean-produced counterfeit U.S. currency, the press release alleges.

September 19, 2005: The participants in the six-party talks conclude a joint statement of principles to guide future negotiations.

According to the statement, North Korea commits “to abandoning all nuclear weapons and existing nuclear programs and returning, at an early date, to the Treaty on the Non-Proliferation of Nuclear Weapons and to IAEA safeguards.” It also calls for the 1992 Joint Declaration of the Denuclearization of the Korean Peninsula, which forbids the two Koreas from possessing uranium-enrichment and plutonium-separation facilities, to be “observed and implemented.” Washington affirms in the statement that it has no intention to attack or invade North Korea.

The statement commits the participants to achieving “the verifiable denuclearization of the Korean Peninsula in a peaceful manner” and says that the parties agree “to take coordinated steps to implement” the agreed-upon obligations and rewards “in a phased manner in line with the principle of ‘commitment for commitment, action for action.’”

The statement says that North Korea “stated that it has the right to peaceful uses of nuclear energy” and that the other parties “expressed their respect and agreed to discuss, at an appropriate time, the subject of the provision” of a light-water nuclear power reactor to Pyongyang. This issue had been controversial during the negotiations and the final agreement was the result of a compromise between Washington and Pyongyang. North Korea insisted that the statement recognize its right to a peaceful nuclear energy program and commit the other participants to provide it with light-water reactors while the United States argued that North Korea should not receive any nuclear reactors.

September 20, 2005: North Korea’s Foreign Ministry states that it is “essential” for the United States to provide light-water reactors to Pyongyang “as early as possible,” adding that Washington “should not even dream” that North Korea will dismantle its “nuclear deterrent” before receiving the reactors. However, a speech from North Korean Vice Foreign Minister Choe Su Hon two days later appears to back away from this formulation.

October 20, 2005: Democratic New Mexico Governor Bill Richardson, who visited North Korea earlier in the month, says North Korean officials told him they had reprocessed the 8,000 spent fuel rods from the Yongbyon reactor, the Associated Press reports.

October 21, 2005: The Treasury Department announces that it has sanctioned eight North Korean entities pursuant to Executive Order 13382 for their unspecified “involvement” in the proliferation of nuclear, chemical, or biological weapons or related delivery vehicles. The action freezes the entities’ U.S. assets and prohibits transactions between these entities and any U.S. citizens or companies. The department had similarly designated those entities’ parent companies in June.

November 9-11, 2005: The fifth round of the six-party talks begins in Beijing.

South Korea and Japan present concrete plans for implementing the September statement. Both countries propose that the participants separate outstanding issues into three categories: the dismantlement of Pyongyang’s nuclear program, provision of economic and energy assistance to North Korea, and Pyongyang’s bilateral issues with Washington and Tokyo.

Disagreements between Washington and Pyongyang continue to block progress. The North Korean delegation focuses almost exclusively on the funds frozen by the September Banco Delta Asia designation.

December 19, 2005: North Korea announces that it will “pursue” the construction of larger “graphite-moderated reactors,” an apparent reference to the two reactors whose construction had been frozen under the Agreed Framework in Pyongyang’s most definitive public statement on the matter.

2006

March 7, 2006: Officials from the U.S. Treasury Department brief North Korea’s deputy director-general for North America, Li Gun, as well as other North Korean officials about the U.S. actions taken with respect to Banco Delta Asia. Li tells reporters afterward that his delegation proposed several methods for resolving U.S. concerns, South Korea’s semi-official Yonhap News Agency reports. Among them was a suggestion to form a joint U.S.-North Korean consultative committee of experts that would discuss such issues as counterfeiting and money laundering.

March 17, 2006: Department of State spokesperson Adam Ereli indicates during a press briefing that issues related to North Korea’s financial system could potentially be discussed in the six-party talks.

March 30, 2006: The Treasury Department announces that it has imposed penalties on a Swiss company, along with one of its owners, for procuring “goods with weapons-related applications” for North Korea.

April 13, 2006: North Korean Vice Foreign Minister Kim Gye Gwan tells reporters that Pyongyang would return to the talks if the United States lifted the freeze of Banco Delta Asia’s funds, which total approximately $25 million.

June 1, 2006: The KEDO Executive Board announces that it has formally terminated its project to build two light-water nuclear reactors in North Korea.

The board says its decision was based on the “continued and extended failure” of North Korea to comply with its relevant obligations under the 1994 Agreed Framework.

According to South Korea’s Unification Ministry, KEDO’s executive board adopted a resolution the previous day saying that Seoul is to “cover the costs arising from the liquidation process,” of the KEDO assets, such as resolving compensation claims from subcontractors. In return, the government-owned Korea Electric Power Corp., the prime contractor for the reactor project, would gain ownership over reactor “equipment and materials” located outside of North Korea. The fate of assets remaining in North Korea, such as vehicles and construction equipment, is unclear.

July 4-5, 2006: North Korea test fires seven ballistic missiles, including its longest-range missile, the Taepo Dong-2. The other six tests include a combination of short- and medium-range Scud-C and Nodong ballistic missiles, launched from the Kittaraeyong test site. Although the tests of the six short-range missiles appear to be successful, the Taepo Dong-2 fails less than a minute after launch.

A July 4 State Department press statement describes the launches as a “provocative act” that violated North Korea’s voluntary moratorium on flight-testing longer-range missiles, which Pyongyang had observed since September 1999.

Japan and South Korea punish North Korea for conducting the tests, with Tokyo imposing sanctions on Pyongyang and Seoul halting food and fertilizer assistance.

July 15, 2006: The UN Security Council adopts Resolution 1695 condemning North Korea’s missile launches. The resolution calls on Pyongyang to return to the six-party talks and “demands” that the country suspend its ballistic-missile activities and re-establish its flight-testing moratorium.

The resolution also requires states to prevent missiles and related “items, materials, goods and technology” from being transferred to North Korea’s missile or weapons of mass destruction programs. In addition, it requires countries to prevent the procurement of such items from Pyongyang and the transfer of any “financial resources in relation to” North Korea’s weapons programs.

North Korea’s Foreign Ministry states the next day that Pyongyang will “not be bound” by the resolution.

September 19, 2006: Japan and Australia announce that they have adopted sanctions targeting multiple foreign entities tied to North Korea’s ballistic missile and nuclear, chemical, and biological weapons programs in response to resolution 1695.

The two countries each punish the same 12 organizations, as well as a Swiss citizen. All entities are already subject to similar U.S. sanctions. Japan also sanctions three additional institutions.

October 3, 2006: North Korea’s Foreign Ministry issues a statement asserting that Pyongyang “will in the future conduct a nuclear test under the condition where safety is firmly guaranteed.” Apparently signaling a degree of restraint, the statement also says that North Korea will refrain from the first-use of nuclear weapons, “strictly prohibit any …nuclear transfer,” and “do its utmost to realize the denuclearization of the [Korean] peninsula.”

October 9, 2006: North Korea conducts an underground nuclear test near the village of P’unggye. Most early analyses of the test based on seismic data collected by South Korean, Japanese, and U.S. institutes estimates the yield to be below one kiloton. Russian estimates differed significantly, and Foreign Minister Sergei Ivanov said Oct. 10 that the estimated yield was between 5 and 15 kilotons.

October 11, 2006: North Korea’s Foreign Ministry states that its “nuclear test was entirely attributable to the US nuclear threat, sanctions and pressure,” adding that North Korea “was compelled to substantially prove its possession of nukes to protect its sovereignty.” The statement also indicates that North Korea might conduct further nuclear tests if the United States “increases pressure” on the country.

However, the Foreign Ministry also says that North Korea remains committed to implementing the September 2005 joint statement, arguing that the test “constitutes a positive measure for its implementation.” Additionally, Pyongyang “still remains unchanged in its will to denuclearize the peninsula through dialogue and negotiations,” the Foreign Ministry statement says, adding that the “denuclearization of the entire peninsula was President Kim Il Sung’s last instruction and an ultimate goal” of North Korea.

October 14, 2006: The UN Security Council adopts Resolution 1718. The measure demands that North Korea refrain from further nuclear tests and calls on Pyongyang to return to the six-party talks and abandon its nuclear weapons. It also imposes additional sanctions on commerce with Pyongyang, widening the range of prohibited transactions beyond those banned under Resolution 1695.

November 28-December 1, 2006: The Chinese, North Korean, South Korean, and U.S. envoys to the six-party talks hold consultations in Beijing to discuss resuming the fifth round of talks. During the consultations, North Korean envoy Kim Gye Gwan states that North Korea is ready to implement the September 19, 2005 joint statement and abandon its nuclear program, but would not do so “unilaterally.”

December 18-22, 2006: The fifth round of six-party talks resumes in Beijing. The United States presents a multistage denuclearization plan, but the talks make no progress towards implementing the September 19, 2005 joint statement—in part due to continued disagreements regarding the North Korean funds frozen by the United States in Banco Delta Asia. The parties agree to meet again “at the earliest opportunity.”

2007

February 8-13, 2007: The six-party talks concludes its fifth round with an agreed “action plan” of initial steps to implement the September 19, 2005 joint statement on North Korea’s denuclearization.

According to the action plan, North Korea is to halt the operation of its nuclear facilities at Yongbyon during a 60-day initial phase in return for an initial shipment of 50,000 tons of heavy-fuel oil.

The action plan also establishes five working groups to “discuss and formulate specific plans” regarding: economic and energy cooperation; denuclearization; implementation of a “Northeast Asia Peace and Security Mechanism;” North Korean relations with the United States; and North Korean relations with Japan.

The statement indicates that, following the shutdown of North Korea’s nuclear facilities at Yongbyon, Pyongyang is to provide a complete declaration of all of its nuclear programs and disable all of its existing nuclear facilities in return for an additional 950,000 tons of heavy-fuel oil or its equivalent.

In addition to helping to provide energy aid to North Korea, the United States agrees to begin the process of removing Pyongyang from its list of state sponsors of terrorism and to stop the application of the Trading with the Enemy Act toward North Korea.

March 13-14, 2007: IAEA Director-General Mohamed ElBaradei visits North Korea and meets with three officials, including the head of the North Korean General Department of Atomic Energy, Ri Je Son. During the meetings, ElBaradei invites North Korea to return to the IAEA as a member state and discusses the agency’s monitoring and verification role during the implementation of a February 13 six-party talks agreement.

March 19-22, 2007: The sixth round of six-party talks begins in Beijing. The discussions are suspended when North Korean negotiators fly home after four days, explaining that they will not participate until the United States transfers $25 million in frozen North Korean funds held in Banco Delta Asia.

On March 19, Treasury Department Deputy Assistant Secretary for Terrorist Financing and Financial Crimes Daniel Glaser announces that the two countries had “reached an understanding” regarding the frozen funds, with Washington accepting a North Korean proposal that the funds would be transferred to a North Korean account in the Bank of China in Beijing. North Korea also pledges that the funds “will be used solely for the betterment of the North Korean people, including for humanitarian and educational purposes.”

April 10, 2007: The United States agrees to unfreeze the $25 million in North Korean funds frozen in its Banco Delta Asia account. U.S. officials insist, meanwhile, that North Korea, “live up to the assurances that these funds will be used for the betterment of the North Korean people and for humanitarian purposes.”

June 25, 2007: A North Korean Foreign Ministry spokesman confirms that the Banco Delta Asia funds were transferred to Pyongyang and that North Korea would begin shutting down its Yongbyon nuclear facilities. An IAEA delegation led by Deputy Director-General for safeguards Ollie Heinonen arrives in Pyongyang the following day to discuss the verification procedures for the shutdown.

July 16, 2007: The IAEA confirms the shutdown of the Yongbyon nuclear facilities.

July 18-20, 2007: The six-party talks reconvenes its sixth round in Beijing. The meeting concludes with a joint communiqué indicating that the five working groups will all meet by the end of August in preparation for another round of plenary talks in September.

September 6, 2007: Israel carries out an air-strike destroying a Syrian facility of an undetermined purpose. Early press reports quoting unnamed U.S. officials suggest that the target of the airstrike was a nuclear facility under construction with North Korean assistance. Days after the strike, Syrian officials deny that the facility was nuclear related, while Israeli and U.S. officials only confirm that an air-strike was carried out. In the following months, Assistant Secretary of State Christopher Hill states on several occasions that he has raised the issue of the Syrian facility with North Korea. U.S. officials later indicate that the facility was believed to have been a nearly completed nuclear reactor modeled on the North Korean nuclear reactor at Yongbyon.

September 11-14, 2007: A team of Chinese, Russian, and U.S. experts visit North Korea to examine the Yongbyon nuclear facilities to determine the steps necessary to disable them. The experts team agrees on a draft disablement plan with North Korean officials which is to be considered by the next plenary meeting of the six-party talks.

September 27-October 3, 2007: The sixth round of six-party talks meets to discuss how to proceed with the second phase of the February 13 agreement. On October 3, the participants issue a joint statement in which North Korea agrees that, by December 31, it would provide a “complete and correct declaration of all its nuclear programs – including clarification regarding the uranium issue,” and disable its Yongbyon nuclear facilities. Pyongyang also agrees to disable all other nuclear facilities subject to the September 2005 joint statement and not to transfer nuclear material or technology abroad.

In return, the six-parties agree that North Korea would receive the remaining 900,000 tons of heavy-fuel oil or its equivalent pledged in the February 13 agreement.

The United States also agrees that it will fulfill its commitments to begin removing North Korea from its list of state sponsors of terrorism and “advance the process of terminating the application of the Trading with the Enemy Act” toward North Korea “in parallel with” North Korea’s denuclearization actions.

October 2-4, 2007: South Korean President Roh Moo-hyun travels to Pyongyang to meet with North Korean leader Kim Jong Il to discuss prospects for reconciliation and economic cooperation. It is the second time in history that such summit-level discussions have been held.

The summit concludes with a an eight-point joint declaration in which both sides agree to take steps toward reunification, ease military tensions, expand meetings of separated families, and engage in social and cultural exchanges. The declaration also expresses a “shared understanding” by the two countries “on the need for ending the current armistice mechanism and building a permanent peace mechanism.”

November 5, 2007: A team of U.S. experts arrives in North Korea to begin leading the disablement of the Yongbyon nuclear facilities. The disablement process consists of 11 agreed steps to be completed by the December 31 deadline stipulated in the October 3 agreement. Funding for the disablement process is provided by the State Department’s Nonproliferation and Disarmament Fund (NDF), which is ordinarily reserved for short-term emergency nonproliferation needs.

December 19, 2007: Grand National Party candidate Lee Myung-bak is elected president of South Korea, ushering in the first conservative government in Seoul in 10 years.

December 21, 2007: The Washington Post reports that U.S. technical teams discovered traces of enriched uranium on aluminum tubes North Korea shared with U.S. officials in November. According to the report, it is unclear whether the contamination originated in North Korea as a result of uranium enrichment carried out by Pyongyang, or if North Korea imported materials which were contaminated abroad and placed these materials in close proximity to the aluminum tubes.

2008

January 2, 2008: Following a December 31, 2007 deadline for North Korea to provide a complete and correct declaration on its nuclear programs and disable its Yongbyon nuclear facilities, State Department spokesman Sean McCormack indicates that “some technical questions about the cooling of the fuel rods” was the reason behind the failure to meet the year-end deadline for disablement. He added that Washington would continue to press Pyongyang for its nuclear declaration.

January 4, 2008: KCNA releases a North Korean Foreign Ministry statement declaring that North Korea “worked out a report on the nuclear declaration in November last year and notified the U.S. side of its contents.” The statement also accuses the other parties of falling behind on their commitments under an October 2007 agreement, including delays in the delivery of heavy-fuel oil to North Korea. Pyongyang indicated that it would slow down the disablement process in response to delays in the delivery of energy assistance.

February 6, 2008: Assistant Secretary of State Christopher Hill testifies before the Senate Foreign Relations Committee and indicates that, in the Fall of 2007, North Korea showed U.S. officials two conventional weapons systems it claimed were the recipients of the thousands of aluminum tubes Pyongyang imported years ago which raised suspicions of a uranium enrichment program. He informs the committee that while the tubes did not work with one of these systems, the U.S. government accepts that the tubes were currently being used for a second conventional weapons system.

Hill also requests from Congress a limited waiver of 1994 Glenn amendment sanctions imposed on North Korea following its nuclear test in 2006. These sanctions, which prohibit the provision of non-humanitarian assistance to non-nuclear-weapon states which have detonated a nuclear weapon, prevent the National Nuclear Security Administration from carrying out work to dismantle the Yongbyon nuclear facilities.

February 25, 2008: South Korean President-elect Lee Myung-bak is inaugurated.

March 13-14, 2008: Assistant Secretary of State Christopher Hill and North Korea Vice-Foreign Minister Kim Gye Gwan meet in Geneva to discuss ways to make progress on North Korea’s declaration, including the consideration of a compromise approach to the declaration format.

The meeting ends inconclusively.

April 8, 2008: Assistant Secretary of State Christopher Hill and North Korea Vice-Foreign Minister Kim Gye Gwan meet in Singapore for additional discussions on the North Korean declaration.

May 8, 2008: North Korea provides a U.S. delegation in Pyongyang with about 18,000 pages of documentation detailing the operations of two of its primary plutonium-related facilities at Yongbyon: a five megawatt nuclear reactor and a reprocessing facility. The records date back to 1986.

June 24, 2008: Assistant Secretary of State Christopher Hill tells reporters that North Korea’s upcoming nuclear declaration will consist of a “package of items” listing all nuclear materials and programs. The package will reportedly include a formal accounting of North Korea’s plutonium and plutonium-related nuclear facilities and side-documents regarding nuclear proliferation and uranium enrichment. Hill says the declaration will not include an accounting of nuclear weapons, which “are to be determined at a subsequent phase.”

June 26, 2008: Pyongyang delivers a declaration of its nuclear programs to China, the six-party talks chair. The declaration reportedly indicates that North Korea separated a total of about 30 kilograms of plutonium, and used about 2 kilograms for its 2006 nuclear test.

The statement also establishes a timeline for completing the disablement of North Korea’s key nuclear facilities and the energy assistance being provided to Pyongyang in return, stating that both processes would be “fully implemented in parallel.”

Mid-July, 2008: The United States tables a draft verification protocol describing procedures used to verify all elements of North Korea’s nuclear programs, including uranium enrichment, weapons, and proliferation. The protocol includes provisions for access upon request for any declared or undeclared site and lists technical recording and detection measures inspectors could undertake.

According to a State Department summary, the new agreement gives inspectors access to all 15 declared sites related to North Korea’s plutonium production program as well as undeclared sites “by mutual consent.” It also allows inspectors to carry out “scientific procedures” such as sampling.

In response to the verification agreement, the United States removes North Korea from the State Department’s terrorism list.

October 13, 2008: KCNA issues a North Korean Foreign Ministry statement indicating that, following its removal from the State Department’s terrorism list, Pyongyang will resume disabling its key nuclear facilities at the Yongbyon nuclear complex.

November 13, 2008: The North Korean Foreign Ministry issues a statement which denies that Pyongyang agreed to allow inspectors to carry out sampling at its nuclear facilities.

Early December 2008: The United States completes the final shipment of its 200,000 tons of heavy fuel oil pledged to North Korea, bringing the total energy assistance to about 550,000 of 1 million tons.

December 8-11, 2008: Six-party discussions on verification, disablement, and energy assistance in Beijing end in stalemate due to a failure to reach agreement on verification. U.S. officials later claim that North Korea refused to agree in writing what it agreed verbally in October. The six parties issue a chairman’s statement in which they agree “to implement in parallel the disablement of the Yongbyon nuclear facilities and the provision of economic and energy assistance.”

December 12, 2008: State Department spokesperson Sean McCormack says that heavy fuel oil shipments to North Korea will not continue without a verification agreement, stating that “there is an understanding among the parties...that fuel oil shipments will not go forward absent progress.” China and Russia deny such an understanding and indicate that they intend to complete their share of the energy assistance.

May 24, 2018: North Korea reports that it destroyed its nuclear testing site at Punggye-ri, setting off explosions to destroy the north, west and south portals to tunnels that could have been used to test nuclear weapons. It is not clear if North Korea completely destroyed the long-abandoned east portal. No nuclear experts were granted access to verify the destruction of the test site. North Korea did transport several international journalists to observe the explosions from a distance. 

In a letter to North Korean leader Kim Jong Un, President Trump cancels the U.S.-North Korean summit scheduled for June 12 in response to "tremendous anger and hostility" displayed by North Korea in a statement the previous day.

The European Phased Adaptive Approach at a Glance

January 2019

Contact: Kingston Reif, Director for Disarmament and Threat Reduction Policy, (202) 463-8270 x104

Updated: January 2019

On September 17, 2009, President Obama announced that the U.S. would pursue a “Phased Adaptive Approach” to missile defense in Europe. The new approach is centered on the Aegis missile defense system and is being deployed in three main phases from 2011 to perhaps 2020. A fourth phase to have been fielded after 2022 was cancelled in March 2013. [For more on this development, please see, "Pentagon Shifts Gears on Missile Defense"]

The European Phased Adaptive Approach (EPAA) is the U.S. contribution to NATO’s missile defense system and is designed to protect Europe against short-, medium-, and intermediate-range ballistic missiles launched from Iran. The approach consists of sea- and land-based configurations of the Aegis missile defense system, the centerpiece of which is the Standard Missile-3 (SM-3) interceptor. A new, more capable version of the SM-3 is being developed, and the system will be increasingly integrated with an evolving network of land and space-based sensors. According to the Obama administration, the plan uses technology that is both “proven” and “cost-effective,” and will be able to adapt as threats evolve.

The EPAA broke with the plans pursued by the Bush administration. The Bush plans had called for deployment of a ground-based missile defense system in Europe, similar to the system deployed in California and Alaska. This included bilateral agreements to station ground-based interceptors in Poland and a radar installation in the Czech Republic.

As part of the EPAA, Turkey is hosting a radar at Kürecik, Romania is hosting an Aegis Ashore site at Deveselu Air Base , Germany is hosting a command center at Ramstein Air Base, and Poland will host another Aegis Ashore site at the Redzikowo.

Phase 1, consisting of the radar in Turkey, command center in Germany, and deployed ballistic missile defense (BMD)-capable Aegis ship by the U.S. Navy, has been operational since 2012. In May 2016, NATO declared operational the Romania Aegis Ashore site as part of EPAA Phase 2. At NATO’s July 2016 Warsaw summit, NATO declared the Initial Operational Capability (IOC) of the NATO ballistic missile defense system and is progressing towards full operational capability. Phase 3 will see the deployment of the Poland Aegis Ashore system perhaps by FY2020 instead of the original 2018 target. The Missile Defense Agency says the completion of the Poland site has been delayed by at least a year due to contractor performance issues. 

The following chart provides an overview of the different EPAA phases. It contains information on the planned scheduling of the phases, the deployment platforms, missile upgrades and the sensors which will be integrated into the system. More has been disclosed about the earlier phases; some of the specifics of the later phases are still to be determined.

 

Phase 1, Deployed

Missile Platforms and Numbers

      • In March 2011, the USS Monterey was deployed to the Mediterranean Sea. This represented "the first sustained deployment of a ballistic missile defense-capable ship" in support of the European PAA.
      • In fiscal year (FY) 2012, 113 SM-3 Block IA and 16 SM-3 Block IB interceptors were delivered and 29 Aegis-equipped BMD ships deployed.
      • The SM-3 IA successfully intercepted a medium-range ballistic missile target in its most recent test on October 20, 2015.

        SM-3 Variant and Numbers

        • SM-3 Block IA interceptors have a velocity of 3 km/second and are designed to engage short- and medium-range ballistic missiles in the mid-course phase.
        • Block IA has a single-color seeker, a 21 inch-diameter booster, and is 13.5 inches in diameter along the rest of the interceptor.
        • Block IA costs between $9 and 10 million per unit.
        • Some SM-2 Block IVs (the SM-3 predecessor) will also be retained for use against missiles in the terminal phase.

        Sensors and Combat System

        • Initially, the system will use sea-based sensors mounted on the Aegis ships, as well as a forward-based mobile X-band radar on land. The first EPAA radar was deployed in Turkey in late 2011.
        • The mobile X-band radar is the AN/TPY-2 manufactured by Raytheon. The U.S. is planning to deploy a total of 18 AN/TPY-2 radars. So far, seven have been produced, and two are currently deployed in Israel and Japan.
        • In May 2018, the GAO reported a total of seven AN/TPY-2 radars are deployed to support regional defense. Four radars are deployed to Pacific Command (two for use in forward-based mode and two for use in terminal mode), two are deployed to European Command and one is deployed to Central Command.
        • The sensors and interceptors will be brought together under the Aegis combat system. This is a system capable of tracking 100 simultaneous targets. Phase 1 will primarily use Aegis version 3.6.1 software.
        • According to the Defense Science Board (2011), the current Aegis shipboard radar is inadequate to support the EPAA mission, and the future Navy ship-based Air and Missile Defense Radar (AMDR) is needed.
        • U.S. and European BMD systems are integrated for battle management at Ramstein Air Force Base in Germany.

         

         

        Phase 2, Operational as of May 2, 2016

        Missile Platforms and Numbers

            • Phase 2 includes interceptors on land in the first "Aegis-Ashore" deployment in Romania. Interceptors have also been mounted on an increasing number of Aegis BMD ships in support of global missions.
            • According to the FY2019 budget submission, by FY2019, the U.S. Navy plans to have 41 Aegis BMD ships, and 57 by FY2023.
            • The first "Aegis-Ashore" site in Romania is equipped with one land-based Aegis SPY-1 radar and 24 SM-3 missiles.
            • Phase 2 achieved a Technical Capability Declaration in 2015, meaning that the site transitioned from the construction to integration phase. In May 2016, NATO declared the Romania Aegis Ashore site operational. NATO declared the IOC of the system in July 2016. 

              SM-3 Variant and Numbers

              • Phase 2 included the SM-3 Block IB variant, also with a velocity of 3 km/sec. This interceptor differs from the Block IA in its "seeker" technology, consisting of a two color seeker, or "kill warhead," and improved optics.
              • The SM-3 Block IB missiles are placed in the MK-41 launcher.
              • According to the FY2017 budget submission, the inventory of SM-3 Block IB interceptors stood at 92 in 2016, with 128 planned for FY17. By FY21, the MDA is planning an inventory of 271 Block IB interceptors.
              • The Block IB is estimated to cost between $12 and 15 million per interceptor.

              Sensors and Combat Systems

              • In Phase 2, sensors were integrated with updated versions of the Aegis combat system. BMD ships carry versions 3.6.1, 4.0.1, and 5.0. 

               

              Phase 3, Planned Deployment Date: ~2020

              Missile Platforms and Numbers

                • Phase 3 will see the introduction of the second “Aegis-Ashore” site in Poland with another SPY-1 radar and 24 SM-3 missiles. This will supplement the deployments at sea and in Romania and will extend coverage over a greater percentage of Europe.

                SM-3 Variant and Numbers

                • Phase 3 will include the SM-3 Block IIA interceptor. This new variant will be faster than Block I (4.5 km/sec vs. 3 km/sec.), with a 21 inch diameter for the whole length of the missile allowing for more fuel and hence a more powerful motor. This will give the system an “enhanced” capability to address intermediate-range ballistic missiles and potentially a “limited” capability to address intercontinental ballistic missiles (ICBMs).
                  • The first intercept test of the new SM-3 IIA interceptor occurred in February 2017 and was successful. However, the second and third intercept tests of the missile in June 2017 and January 2018 failed to destroy their targets. There were two more tests before the end of 2018 on Oct. 26 and Dec.11, both successful, with the December test particularly notable for being the first successful intercept of an IRBM target and using the ability to "engage on remote" using a forward-based sensor. 
                  • Four Block IIAs are planned for delivery in FY2018, with an additional 27 planned for FY2021.

                Sensors and Combat Systems

                  • In Phase 3, the United States will deploy both the Airborne Infrared (ABIR) sensor platform, a system designed to track significantly larger numbers of incoming missiles, with the goal of being able to track “hundreds” of missiles simultaneously. 
                  • Aegis BMD ships are scheduled to be equipped with version 5.1 of the combat system software in this time-frame.
                  • Phase 3 of the EPAA is scheduled to include an “engage on remote” capability for Aegis interceptors to conduct operations based entirely on off-board radar information, thereby expanding the range of the Aegis systems. In this capability, the interceptor can be both launched and guided to intercept by sensors remote from the launching ship.

                     

                    Phase 4, Cancelled March 2013

                    Missile Platforms and Numbers

                      • The platforms supporting the SM-3 interceptors under Phase 4 would have remained the same as those deployed under Phase 3 – sea-based platforms and the “Aegis-Ashore” deployments in Romania and Poland.

                      SM-3 Variant and Numbers

                      • The SM-3 Block IIB; planned numbers unknown. Was planned to have an improved seeker and a higher performance booster, with a velocity of 5-5.5 km/sec. Was expected to marginally improve the Block IIA’s “limited” capability to counter ICBMs.
                      • According to the Defense Science Board (2011), the SM-3 IIB's planned mission to intercept targets prior to the deployment of multiple warheads or penetration aids – known as "early intercept" – requires "Herculean effort and is not realistically achievable, even under the most optimistic set of deployment, sensor capability, and missile technology assumptions.”
                      • The Block IIB was in the conceptual stage.

                      The Aegis system is deployed on 17 U.S. Navy destroyers and cruisers in the region that conduct ballistic missile tracking, targeting, and engagement capability. These Aegis BMD ships can engage short-(SRBMs), medium- (MRBMs), and intermediate-range ballistic missiles (IRBMs) in either the midcourse or terminal phase of flight. They can also contributed to the defense of the U.S. homeland by detecting and tracking of intercontinental ballistic missiles (ICBMs) and sending this data to Ground-Based Interceptors (GBIs) based in Alaska and California to engage.

                      Program Overview/Elements:

                      • Aegis provides defenses against regional ballistic missile threats and can also contribute to homeland defense through continuous long-range surveillance and tracking of ICBMs.
                      • All deployed Aegis BMD-capable ships are equipped with either SM-3 Block IA (first-generation) or Block IB (second-generation) missile interceptors for engaging missiles in the midcourse phase—that is, while it is in space.
                      • In addition, Aegis ships can use SM-2 and SM-6 missiles to engage SRBM targets inside the atmosphere in the terminal phase using explosive warheads rather than the kinetic hit-to-kill vehicles used by the SM-3.
                      • Aegis BMD ships carry the AN/SPY-1 radar, a phased-array S-band radar system, for detection and tracking of ballistic missiles.
                      • As of December 2018, the system has a record of 40 successful intercepts in 49 attempts against ballistic missile targets.

                      Status:

                      • As of 2016, there are 33 Aegis BMD-capable U.S. navy ships deployed around the world, with 17 of those assigned to the Pacific Fleet. Two additional Aegis ships are being repaired as of early 2018.
                      • Of these 17 Pacific Fleet BMD ships: 8 are homeported in San Diego, CA; four in Pearl Harbor, HI; and five in Yokosuka, Japan.

                      Current Developments:

                      • In its FY 2019 budget request, MDA projected having 57 Aegis BMD-capable ships and 560 SM-3 interceptors—including 48 Block IIA interceptors—deployed by FY 2023. MDA also projected a total deployment of 41 Aegis BMD-capable ships by the end of 2019.
                      • Along with Japan, the Pentagon is developing the SM-3 Block IIA missile, a 21-inch diameter variant of the SM-3 with an extended range and higher velocity than the current SM-3 interceptors.
                        • Set for deployment beginning in 2018 on U.S. Navy and Japanese Maritime Self-Defense Force Aegis capable ships.
                        • The first intercept test of the new SM-3 IIA interceptor occurred in February 2017 and was successful. However, the second and third intercept tests of the missile in June 2017 and January 2018 failed to destroy their targets. The third and fourth tests in October and December of 2018 were successful, and notably the December 2018 test was the first time the interceptor intercepted an IRBM-class target and "engage on remote" using a forward-based sensor. 
                      • The AN/SPY-6 radar (also known as AMDR) is being developed as a replacement to the AN/SPY-1. Once complete, the AN/SPY-6 will be able to detect thirty times as many targets that are “half the size, at twice the distance” of the current AN/SPY-1.

                      Hawaii

                      Home to U.S. Pacific Command Headquarters, Hawaii is defended by the Ground-based Midcourse Defense (GMD) system designed to counter strategic threats. It also hosts the Sea-Based X-Band Radar and is slated to host a new long-range discrimination radar system by 2023.

                      Sea-Based X-Band Radar (SBX)

                      Program Overview/Key Elements:

                      • A massive phased-array X-band radar housed inside a 120-foot diameter radome and supported on a self-propelled, floating platform which primarily acts as the principle midcourse sensor for the strategic BMD system.
                      • Its radar has a 2,500-mile range and is meant to serve in an advanced position to track incoming missiles, discriminate between warheads and decoys or countermeasures, and relay this data to interceptor missiles. Many have cast doubt on SBX’s ability to fulfill this role, primarily because of its extraordinarily narrow 25-degree field of view, compared to 90-120 degrees in other air defense radars.
                      • SBX could also support regional BMD systems to protect troops in forward-deployed positions.

                      Status:

                      • SBX spends most of its time on “limited test support status” in port in Pearl Harbor, Hawaii. It operates at sea in support of BMDS tests or when the security environment dictates that it may be needed.

                      Current Developments:

                      • In a February 2018 press briefing on the agency’s FY 2019 budget request, MDA spokesman Gary Pennett announced that MDA had extended the SBX’s ability to stay at sea to “closer to 300 days.”

                      Homeland Defense Radar-Hawaii (HDR-H)—(planned)

                      Overview/Key Elements:

                      • A planned land-based, long-range discrimination radar that MDA plans to field in 2023. HDR-H would improve the ability of the GMD homeland defense system to protect Hawaii from ICBMs.

                      Status:

                      • PACOM Commander Adm. Harry Harris told Congress in February 2018 that the HDR-H is in the final phase of the siting process.
                      • MDA spokesman Gary Pennett said that same month that a second, similar radar will be deployed to an as-yet undetermined location in the Pacific (HDR-P) in 2024 to add to the sensor architecture.
                      • For fiscal year 2019, the Missile Defense Agency requested $62 million for HDR-H, and an additional $34 million for HDR-P.

                      Guam

                      Guam is the closest U.S. territory to the Korean peninsula and Andersen Air Base and Naval Base Guam are among several possible targets for DPRK intermediate-range ballistic missiles (IRBMs). With 7,000 U.S. servicemen stationed in Guam and 163,000 U.S.-citizen residents living on the island, the U.S. military sought to enhance BMD coverage of the island already provided by Aegis BMD ships by deploying a THAAD battery.

                      Terminal High Altitude Area Defense (THAAD)

                      Overview/Key Elements:

                      • A THAAD battery consisting of 6 launchers with 8 interceptors per launcher was deployed to Andersen Air Base, Guam in 2013 along with its associated AN/TPY-2 radar and fire control stations.
                      • Adm. Harry Harris, commander of U.S. Pacific Command, reiterated in February 2018 testimony to Congress the Pentagon’s view that THAAD is needed on Guam to protect against North Korean intermediate-range ballistic missiles.
                      • THAAD is designed to intercept ballistic missiles in their terminal phase as a ballistic missile is reentering the atmosphere on the way to its target, meaning it would have a chance to attempt an intercept at a later stage than an Aegis ship and thus provide an additional layer of BMD coverage.

                      South Korea

                      BMD coverage of South Korea is centered on engaging missiles in the terminal phase of flight. U.S. and South Korean forces operate several U.S.-made BMD platforms on the peninsula to defend against short- and medium-range North Korean missiles, including a U.S.-operated THAAD battery and several U.S.- and South Korean-operated Patriot batteries on land. South Korea is developing several indigenous short-range BMD systems, under its Korean Air and Missile Defense (KAMD) system scheduled to be deployed by the early 2020s. U.S. and South Korean Aegis BMD ships also patrol South Korean waters.

                      U.S.-operated systems:

                      Terminal High Altitude Area Defense (THAAD)

                      Overview/Key Elements:

                      • The U.S. Army deployed a THAAD battery, consisting of six launchers with eight interceptors per launcher and associated radar and fire control equipment in April 2017 to defend against North Korean MRBMs and SRBMs.
                      • THAAD’s position in Seongju is too far south to protect Seoul or U.S. forces stationed on the border and at Camp Humphreys. Designed to intercept missiles within a 124-mile range, the THAAD battery is positioned to potentially defend US troops landing and disembarking from the port of Busan in the southeast in the event that the United States deploys additional forces to the peninsula. It could also defend major urban areas in the southern part of the peninsula, amounting to coverage for roughly 10 million South Koreans.

                      Patriot Advanced Capability-3 (PAC-3)

                      Overview/Key Elements:

                      • The United States is believed to operate 8 PAC-3 batteries in classified locations around South Korea, likely deployed around key U.S. military bases.
                      • PAC-3 system can share tracking and targeting data as well as engage short-range ballistic missiles at a lower altitude than THAAD, allowing for layered but overlapping terminal-phase coverage.

                      Status:

                      • In August 2017, the U.S. Army announced that it had completed upgrading its Patriot systems at Osan Air Base in Seoul to PAC-3.

                      South Korean-operated systems:

                      Aegis ships

                      Overview/Key Elements:

                      • South Korea operates 3 Sejong-Daewang (Sejong the Great, or KDX-III)-class destroyers that are equipped with a version of the Aegis system, Baseline 7, that is not BMD-capable. South Korea’s ships can communicate with and relay targeting data between U.S. Aegis BMD ships, but cannot currently track or engage ballistic missiles.
                      • While the Aegis system deployed on South Korean ships can link data with U.S. ships, it cannot directly link data to Japanese Aegis BMD ships because they do not share a common encryption system.
                      • According to a 2009 U.S. Defense Security Cooperation Agency announcement, South Korea already has SM-2 missiles in its inventory with terminal-phase BMD potential should it upgrade its Aegis systems from Baseline 7 to Baseline 9.

                      Current Developments:

                      • The next generation of three KDX-III destroyers, set to enter into service in 2023, 2025, and 2027, will be built with the latest Aegis Baseline 9 software and will be fully capable of BMD detection and tracking. Many analysts have also speculated that these destroyers will be equipped with a version of the SM-3 missile interceptor to give them an engagement capability as well.
                      • Several press reports, citing anonymous South Korean defense officials, have hinted that South Korea is looking to upgrade its three operating KDX-III destroyers with a newer version of Aegis that would give them BMD capability in the near term.

                      Korean Air and Missile Defense (KAMD)

                      Overview/Key Elements:

                      • KAMD is a multi-platform, short-range air and missile defense concept that South Korea has been developing since 2006 to enhance its protection against DPRK SRBMs, cruise missiles, and light aircraft.
                      • In April 2014, South Korea announced it was upgrading its 8 existing Patriot Advanced Capability-2 (PAC-2) batteries to PAC-3 by the end of 2018 and would buy PAC-3 missiles by 2020.
                      • South Korea is developing the Cheongung Korean medium-range surface-to-air missile (KM-SAM), intended to intercept DPRK SRBMs and MRBMs at a relatively low altitude, similar to PAC-3.
                      • The Korean long-range surface-to-air missile (KL-SAM), under development until 2020, will reportedly be similar to THAAD, operating in a high-altitude, terminal-phase intercept role against SRBMs and MRBMs.

                      Status:

                      • South Korean forces operate 8 PAC-2 and PAC-3 batteries around Seoul (exact locations classified), which compose the only layer of defense for the roughly 20 million South Koreans that are not covered by THAAD.
                      • South Korea is reportedly in the final phase of developing the KM-SAM, which Seoul aims to deploy between 2018 and 2019.

                      Current Developments:

                      • The South Korean Defense Acquisition Program Administration approved a planned PAC-3 Missile Segment Enhancement (PAC-3 MSE) system purchase on Feb. 7, 2018.
                      • The PAC-3 MSE systems will provide an additional layer of terminal-phase defense to the PAC-3 systems, since the MSE system can reportedly engage medium- and short-range ballistic missiles at an altitude of 40 km, twice that of the PAC-3. PAC-3 MSE missiles feature new software that improves its targeting as well as a two-stage rocket booster that extends the range of interceptors to 19 miles.

                      Japan

                      Japan has heavily invested in an integrated BMD system and has focused on midcourse defense with the Aegis system. Japan operates four Aegis BMD ships with plans to build four more by the early 2020s. The cabinet in December 2017 approved a plan to build two Aegis Ashore sites by the early 2020s. U.S. Aegis ships and U.S. and Japanese Patriot batteries offer another layer of defense.

                      U.S.-operated systems:

                      Aegis BMD Ships

                      Overview/Key Elements:

                      • The U.S. 7th Fleet, which is based in Japan and operates in East Asia, has six destroyers and one cruiser equipped with Aegis BMD systems that are assigned to BMD operations.
                      • These Aegis ships are equipped with SM-3 Block IA and Block IB interceptors and SPY-1 radars. They can relay or receive data to and from other Aegis ships—including both Japanese and South Korean Aegis ships—and are interoperable with Aegis and land-based systems such that their interceptors can be “launched on remote” using tracking data from off-board sensors.

                      Status:

                      • There are only five U.S. Aegis BMD ships permanently stationed in Japan. Two additional ships are under repair and likely will return to service in summer 2018.
                      • The Navy does not announce when, where, or which BMD ships patrol in the region, but reportedly half of the Japan-based BMD fleet is at sea at any given time.

                      Patriot Advanced Capability-3

                      Overview/Status:

                      • U.S. forces operate PAC-3 systems in Japan at U.S. military bases, most of which are on the island of Okinawa.
                      • The first U.S. PAC-3 systems were originally deployed in 2006. The deployments were located near Kadena Air Base (Kadena Town, Okinawa City, and Chatan Town), as well as near Kadena Ammunition Storage Area (Yomitan Village, Okinawa City, Kadena Town, Onna Village, and Uruma City).
                      • Movements and deployments of U.S.-operated PAC-3 units in Japan are not publicly available.

                      AN/TPY-2 Radar

                      Overview/Key Elements:

                      • The U.S. operates 2 AN/TPY-2 mobile radar systems—the same radar used in conjunction with THAAD—in Japan.
                      • Since these TPY-2 radars are not paired with THAAD launchers, they are likely operated in the forward-based mode to detect missile launches in North Korea. The radars then relay data to Aegis BMD ships.
                      • Mobile radars can be quickly moved in response to changing needs.

                      Status:

                      • In December 2014, the U.S. military deployed the second AN/TPY-2 radar to a Japanese Air Self-Defense Force base near Kyoto.
                      • The other TPY-2 radar is deployed at Shariki JASDF base in northern Japan.

                      Japanese-operated systems:

                      Aegis BMD

                      Overview/Key Elements:

                      • The Japan Maritime Self-Defense Force (JMSDF) deploys four Kongo-class destroyers equipped with Aegis BMD system and SM-3 Block IA interceptors.
                      • Kongo-class destroyers can link data directly to U.S. (but not South Korean) Aegis destroyers and coordinate missile tracking.
                      • Under Japan’s constitution, it can only attempt to shoot down missiles or missile debris headed toward Japanese territory, meaning that while its Aegis ships could help track DPRK IRBMs headed toward Guam, for example, they could not launch interceptors to engage them.

                      Status:

                      • Japan is modifying two Atago-class destroyers to operate the Aegis system in the near future.
                      • The first Atago-class cruiser was launched on July 30, 2018, the Japanese Ministry of Defense said in a statement. The second is expected to be commissioned in March 2021.

                      Current Developments:

                      • Japan announced in 2013 that it planned to acquire two more Aegis BMD destroyers, which would enter service in 2020 and 2021 and be equipped with Aegis Baseline 9 and SM-3 Block IIA interceptors, bringing its total fleet of BMD ships to eight.
                      • Japan’s Aegis BMD ships are set to begin receiving the SM-3 Block IIA missile, which Japan co-developed with the United States, as soon as it is deployed on U.S. ships. The U.S. State Department cleared an advanced sale of four Block IIA missiles in January 2018. Japan expects that the extended range and higher velocity of the Block IIA will enhance the overlapping coverage of its BMD systems.

                      Aegis Ashore—(planned)

                      Overview/Key Elements:

                      • In December 2017 Prime Minister Shinzo Abe’s Cabinet approved a Defense Ministry plan to purchase two Aegis Ashore systems. Officials confirmed they hope the systems will be operational by 2023.
                      • Armed with SM-3 Block IIA missiles, the two sites will reportedly be able to defend all of Japan against MRBMs and IRBMs and provide overlapping layers of defense with the Aegis BMD fleet. Japanese officials believe this will allow them to reduce the number of JMSDF BMD destroyers deployed.

                      Status:

                      • Citing Japanese Defense Ministry sources, press reports in September 2017 said that Japan was evaluating sites for placing two Aegis Ashore systems on Japan’s western coast (one in the north, one in the south). Akita and Yamaguchi prefectures are seen as possible sites for the units.
                      • The Aegis Ashore units are estimated to cost at least ¥100 billion ($920 million) each.

                      PAC-3

                      Overview/Key Elements:

                      • As of 2015, Japan operates 24 PAC-3 units in 15 military bases, most of them positioned around Tokyo and key locations to act as a final layer of defense beyond Aegis ships.
                      • Being relatively mobile, Japan can and has frequently moved PAC-3 units to shift BMD coverage based on changing threats.
                      • Intended as a point-defense system with an engagement range of just 12 miles, PAC-3 interceptors could also break up missile debris falling over Japan.

                      Status:

                      • As of 2013, PAC-3 systems were known to be deployed to: Aibano in Shiba Prefecture; Naha in Okinawa Prefecture; Hakusan in Tsu, Mie Prefecture; on the grounds of the Ministry of Defense in Tokyo; on the island of Okinawa
                      • Japan announced in August 2017 that it was deploying four PAC-3 systems to Hiroshima, Kochi, Shimane, and Ehime in southwestern Japan.

                      Current Developments:

                      • According to press reports in 2016, Japan plans to upgrade its PAC-3 batteries with Missile Segment Enhancement (MSE) missiles by the 2020 Tokyo Olympics.

                      Early Warning Radar

                      Overview/Key Elements:

                      • Japan operates a network of 28 ground-based air defense radar stations across the country, and of these 11 are BMD capable, stretching the length of Japan’s west coast and facing North Korea and China.
                      • Includes seven older FPS-3 radars that have been upgraded to FPS-4 to be BMD capable and four more advanced FPS-5 radars.
                      • FPS-5 and upgraded FPS-3 radar sites are linked to Japan’s Aegis BMD destroyers and PAC-3 batteries through the Japanese Aerospace Defense Ground Environment (JADGE).

                      Status:

                      • FPS-5 radars are stationed at: Ominato, Sado, Shimo-koshiki island, and Yozadake (Okinawa)
                      • FPS-3UG (FPS-4) radars are stationed at: Tobetsu, Kamo, Otakineyama, Wajima, Kyogamisaki, Kasatoriyama, and Sefuriyama

                      Australia

                      Australia has invested relatively little in its BMD architecture compared to other U.S. allies in the region given its low threat from missiles and has limited BMD detection and tracking capabilities and no engagement capability. But the communications and satellite terminal bases that Australia has hosted for decades as part of U.S. global signals intelligence-gathering efforts have been expanded to play key early warning and communications roles in the U.S. BMD system, and Australia is rolling out a class of Aegis destroyers that could become BMD-capable and will begin production on a class of Aegis BMD frigates in the next five years. Australia’s Aegis fleet will be integrated with U.S., Japanese, and South Korean Aegis ships and may have some engagement capability against MRBMs and IRBMs.

                      U.S.-operated BMD systems:

                      Early Warning Radar/Satellite Stations

                      Overview/Key Elements:

                      • Joint Defense Base Pine Gap, near Alice Springs in central Australia, is a ground control station for U.S. spy satellites that reportedly plays a role in the U.S. BMD command, control, and communications architecture. It monitors missile testing and tracks missile threats in the Asia-Pacific region.
                      • Reportedly, Pine Gap receiving systems can compute the trajectory of DPRK missile launches and send tracking data to other U.S. BMD systems.

                      Status:

                      • Hosts six satellite terminals for the Relay Ground Station, which relays data from early warning satellites (the Space Based Infrared System, or SBIRS) to U.S. and Australian command centers.
                      • Another three radomes are speculated to be associated with MDA’s experimental Space Tracking and Surveillance System (STSS) program.

                      Current Developments:

                      • According to press reports beginning in 2013, the United States and Australia planned to relocate two U.S. advanced radar stations to North West Cape, Western Australia—ostensibly for monitoring satellites in space, according to Australian officials—that could potentially monitor Chinese and DPRK missile launches.

                      Australian-operated BMD systems:

                      Jindalee Operational Radar Network (JORN)

                      Overview/Key Elements:

                      • Jindalee Operational Radar Network (JORN), an over-the-horizon radar system recently constructed in the Australian outback, has the capability to detect missile launches in Asia with its 3000 km range and could potentially be integrated into a multilateral BMD system in the near future as an early warning and tracking capability.

                      Aegis BMD Ships—(under-development)

                      Overview/Key Elements:

                      • Australia is building an Aegis fleet that will field three Hobart-class destroyers equipped with Aegis Baseline 8 and SM-2 missiles, capable of countering cruise missiles but not BMD capable.
                      • Australia’s Aegis ships will be networked with U.S., Japanese, and South Korean Aegis ships, allowing them to share data. The Hobart-class destroyers will not be able to directly participate in BMD operations but could be upgraded.

                      Status:

                      • HMAS Hobart, commissioned in September 2017, and HMAS Brisbane, commissioned in October 2018, are operational Australian Aegis ships, but are not BMD-capable. The final Hobart class ship, NUSHIP Sydney is expected to be delivered to the Royal Australian Navy in March 2020.

                      Current Developments:

                      • Like the Hobart, the Brisbane and the Sydney also won’t have BMD capability until they are upgraded, although press reports have speculated that Australian Defence Department plans intend to upgrade the Hobart-class destroyers to Aegis Baseline 9 and equip them with SM-6 interceptors, making them capable of tracking ballistic missiles and giving them a limited terminal phase intercept capability against SRBMs and MRBMs.
                      • Malcolm Turnbull announced in October 2017 that Australia’s nine new frigates of the Future Frigate project which will begin construction in 2020 will be fitted with the Aegis system and will be BMD capable.
                      • Most analysts speculate that Australia’s Aegis fleet would be used to defend forward-deployed forces and track threats along with allied Aegis ships, but that Australia is not yet moving toward a homeland defense system.

                      U.S. Missile Defense Programs at a Glance

                      An overview of the current U.S. approach to national and regional missile defense, its costs, and sustainability.

                      According to Missile Defense Agency (MDA) estimates, Congress has appropriated over $200 billion for the agency’s programs between fiscal years 1985 and 2019. That total does not include spending by the military services on programs such as the Patriot system or the many additional tens of billions of dollars spent since work on anti-missile systems first began in the 1950s.

                      For nearly two decades, U.S. ballistic missile defense (BMD) policy has sought to protect the homeland against limited long-range missile strikes from states such as Iran and North Korea, but not major nuclear powers like Russia and China, because that mission would pose significant technical, financial, and geopolitical challenges. The United States has also pursued programs to defend U.S. troops and facilities abroad, and some close allies, from attacks by ballistic missiles—and to a much lesser extent cruise missiles.

                      The overall U.S. missile defense effort enjoys strong bipartisan support in Congress. Additionally, many U.S. allies place a high value on missile defense cooperation with the United States.

                      However, the U.S. pursuit of effective missile defenses has been accompanied by intense debate about the technical capabilities of the system and realism of testing, the scope of the ballistic missile threat, the deterrence and assurance benefits of defenses, the cost-effectiveness of shooting down relatively inexpensive offensive missiles with expensive defensive ones, and the repercussions for U.S. strategic stability with Russia and China.

                      According to the Defense Department’s independent testing office, existing U.S. missile defenses have "demonstrated capability" to defend the U.S. homeland against a small number of intercontinental ballistic missile (ICBM) threats that employ "simple countermeasures." The testing office assesses that defenses to protect allies and U.S. troops deployed abroad possess only a “limited capability” to defend against small numbers of intermediate-range ballistic missiles (IRBMs) and medium-range ballistic missiles (MRBMs). The capability of defenses against short-range ballistic missiles is labeled as “fair.” Apart from the point-defense Patriot system, no systems in the U.S. BMD arsenal have been used in combat.

                      Leaders of the U.S. missile defense enterprise have increasingly voiced concerns that the current U.S. approach to national and regional missile defense is unsustainable and that existing defenses must be augmented with emerging capabilities to reduce the cost of missile defense and keep pace with advancing adversary missile threats.

                      Background

                      Bush Administration

                      Ballistic missile defense ranked high among the priorities of the George W. Bush administration, which withdrew the United States from the 1972 Anti-Ballistic Missile (ABM) Treaty in 2002 so that it could attempt to develop and deploy a nationwide defense against a limited number of long-range ballistic missiles. The United States had attempted to implement ground-based long-range ballistic missile defense only once before over the last 50 years. The first effort, Safeguard, was shut down within a few months of being declared operational in October 1975 because Congress concluded it was too expensive and ineffectual. Safeguard was allowed under the ABM Treaty since it was limited to no more than 100 interceptors protecting a single intercontinental ballistic missile (ICBM) base in North Dakota.

                      Obama Administration

                      Upon taking office in 2009, the Obama administration took steps to curtail the Bush administration’s rush to expand the U.S. homeland missile defense footprint and instead place greater emphasis on regional defense, particularly in Europe. The Obama administration decided to alter its predecessor’s plans for missile defense in Europe, announcing on Sept. 17, 2009, that the United States would adopt a European “Phased Adaptive Approach” to missile defense (EPAA). This approach primarily uses the Aegis Ballistic Missile Defense system to address the threat posed by short- and intermediate-range ballistic missiles from Iran. The Aegis system uses the Standard Missile-3 (SM-3) interceptors, which are deployed on Arleigh-Burke class destroyers in the Baltic Sea (Aegis Afloat), as well as on land in Romania and Poland (Aegis Ashore).

                      President Obama's first Secretary of Defense, Robert Gates, also canceled a number of next generation programs, including two designed to intercept missiles during their boost phase, due to "escalating costs, operational problems, and technical challenges."

                      However, while continuing to invest in regional defense, the Obama administration also made substantial investments in homeland defense largely in response to North Korea. The Ground-based Midcourse Defense (GMD) system comprises missile fields in Ft. Greely, Alaska, and Vandenberg Air Force Base, California, and is designed to protect the United States against limited, long-range missile strikes from North Korea and Iran. Despite concerns about the system’s technical viability, from 2013 to 2017, the Obama administration expanded the number of ground-based interceptors (GBIs) in these fields from 30 to 44.

                      The administration also oversaw the deployment of additional regional missile interceptor and sensor capabilities to allies in Northeast Asia in response to North Korea, including the deployment of the terminal high-altitude area defense (THAAD) system to Guam and South Korea and two advanced radars to Japan.

                      Trump Administration

                      In May 2017, pursuant to direction from President Donald Trump and Congress, Defense Secretary James Mattis formally announced the beginning of the department’s Ballistic Missile Defense Review, which is taking a wide-ranging look at missile defense policy and strategy. The review was originally slated to be published alongside the Nuclear Posture Review in February 2018, but has been delayed. The reasons for the delay in the completion of the review are unclear. The Defense Department has stated that the review will focus on defense not only against ballistic missiles, but other missile threats as well, including hypersonic and cruise missiles.

                      Since President Trump’s inauguration, the administration has vowed to expand national and regional missile defense systems of every kind and Congress has supported these efforts. In fiscal year 2018, Congress approved $11.5 billion for the Missile Defense Agency, an increase of $3.6 billion, or 46 percent, from the Trump administration’s May 2017 initial budget request.

                      The appropriation is the largest Congress has ever provided for the agency after adjusting for inflation. The administration, with Congress’ support, is planning to expand the number of ground-based interceptors from 44 to 64 and purchasing additional regional missile defense interceptors.

                      Congress approved another big increase for fiscal year 2019, approving $10.3 billion for the agency, an increase of $1.4 billion above the budget request of $9.9 billion.

                      Ballistic Missile Basics

                      Ballistic missiles are powered by rockets initially but then follow an unpowered, parabolic trajectory toward their target. They are classified by the maximum distance that they can travel, which is a function of how powerful the missile’s engines (rockets) are and the weight of the missile’s warhead. To add more distance to a missile’s range, rockets are stacked on top of each other in a configuration referred to as staging.

                      Four classifications of ballistic missiles:

                      • Short-range ballistic missiles, traveling less than 1,000 kilometers (approximately 620 miles)
                      • Medium-range ballistic missiles, traveling between 1,000–3,000 kilometers (approximately 620-1,860 miles)
                      • Intermediate-range ballistic missiles, traveling between 3,000–5,500 kilometers (approximately 1,860-3,410 miles)
                      • Intercontinental ballistic missiles (ICBMs), traveling more than 5,500 kilometers (approximately 3,410 miles)

                      Short- and medium-range ballistic missiles are referred to as “theater” ballistic missiles, whereas ICBMs or long-range ballistic missiles are described as “strategic” ballistic missiles. The ABM Treaty had prohibited the development of large-scale, nationwide strategic defenses, but permitted development of theater missile defenses, as well as single-site strategic defenses.

                      Three stages of flight:

                      Boost phase:

                      • Begins at launch and lasts until the rocket engines stop firing and pushing the missile away from Earth.
                      • Depending on the missile, lasts between three and five minutes.
                      • Generally the missile is traveling relatively slowly, although toward the end of this stage an ICBM can reach speeds of more than 24,000 kilometers per hour. Most of this phase takes place in the atmosphere (endoatmospheric).

                      Midcourse phase:

                      • Begins after the rockets finish firing and the missile is on a ballistic course toward its target.
                      • Longest stage of a missile’s flight, lasting up to 20 minutes for ICBMs.
                      • During the early part of the midcourse stage, the missile is still ascending toward its apogee, while during the latter part it is descending toward Earth.
                      • During this stage the missile’s warhead(s), as well as any decoys, separate from the delivery platform, or "bus." This phase takes place in space (exoatmospheric).

                      Terminal phase:

                      • Begins when the missile’s warhead re-enters the Earth’s atmosphere (endoatmospheric), and it continues until impact or detonation.
                      • This stage takes less than a minute for a strategic warhead, which can be traveling at speeds greater than 3,200 kilometers per hour.

                      Other Types of Missiles

                      Cruise missiles and hypersonic missiles are two additional categories of missiles. Unlike ballistic missiles, cruise missiles remain within the atmosphere for the duration of their flight. Cruise missiles are propelled by jet engines and can be launched from land-, air-, or sea-based platforms. due to their constant propellants, they are more maneuverable than ballistic missiles, though they are also slower than their ballistic counterparts. Two types of hypersonic missiles are currently under development. A hypersonic boost-glide vehicle is fired by rockets into space and then released to fly to its target along the upper atmosphere. Unlike ballistic missiles, a boost-glide vehicle flies at a lower altitude and can change its intended target and trajectory repeatedly during its flight. The second type, a hypersonic cruise missile, is powered through its entire flight by advanced rockets or high-speed jet engines. It is a faster version of existing cruise missiles.

                      Elements of the U.S. Ballistic Missile Defense System

                      The following charts provides a brief look at some of the major missile defense programs maintained by the United States. It contains information on what type of ballistic missile each defense would be intended to counter and at which stage of the enemy missile’s flight an attempted intercept would take place. Also included are Pentagon estimates on when each defense may have an initial, rudimentary capability as well as when it could be fully operational.

                       

                      GROUND-BASED MIDCOURSE DEFENSE

                      Program & Key Elements

                      • Key element: ground-based missile interceptor consisting of a multistage booster and an exoatmospheric kill vehicle (EKV).
                      • EKV separates from the booster in space and seeks out its target through radar updates and use of its onboard visual and infrared sensors.
                      • The EKV destroys its target by colliding with it. This process is referred to as "hit-to-kill" or "kinetic kill."

                      Designed to Counter

                      • Goal: intercept strategic ballistic missile warheads in midcourse stage.

                      Status

                      • Initially fielded in 2004.
                      • As of the end of 2018, the total cost of the GMD system is estimated to be over $67 billion.
                      • MDA claims that the system has had ten successful intercepts in 18 tests. Only two of the past five intercept tests after 2008 has been successful.
                      • The first test of the GMD system against an ICBM-class target with simple countermeasures took place on May 30, 2017 and was deemed successful.
                      • The next test of the GMD system is scheduled for late 2018 and, for the first time, will involve firing two interceptors against one ICBM target. In a real-world scenario, multiple interceptors would be fired at an incoming missile.

                      Capability / Schedule

                      • As of April 2018, the Pentagon deploys 44 ground-based interceptors (GBIs)–40 at Fort Greely, Alaska, and four at Vandenberg Air Force Base, California. Twenty of the 40 interceptors deployed in Alaska are armed with an older CE-1 kill vehicle that has not had a successful flight intercept test since 2008. In 2017 the Trump administration announced its plan to deploy twenty more GBIs, to be installed in a fourth missile field in Ft. Greely beginning in the FY 2021 timeframe. These interceptors will be armed with the new, under-development Redesigned Kill Vehicle (RKV), which is intended to enhance the performance of the current EKV. The development of the RKV is being accelerated to meet this deployment schedule.
                      • The interceptors are supported by land- and sea-based radars. Early Warning Radar units are being upgraded to support the system. As of June 2018, upgrades have been carried out at Beale Air Force Base, California and at Fylingdales, the United Kingdom, as well as Thule Air Force Base, Greenland and Clear, Alaska. The less powerful, westward-facing COBRA Dane radar on Shemya Island, in the Aleutian archipelago, was also upgraded in February 2010.
                      • Former MDA Director Adm. James Syring told a Senate panel in 2013 that the MDA tests the GMD system “in a controlled, scripted environment based on the amount of time and money each one of these tests costs.” This means there are limits to the realism of the test scenarios.
                      • MDA is investing in the Redesigned Kill Vehicle (RKV), which is intended to enhance the performance of the current EKV, which have been plagued by reliability problems. The RKV is expected to be deployed in 2022.
                      • Following the May 30, 2017 test, the Pentagon's testing office updated its assessment, which had described the GMD system as having only a “limited capability" to defend the U.S. homeland from a small number of simple long-range missiles launched from North Korea or Iran. In a June 6, 2017 memo, the office said that the system has "demonstrated capability" to defend against a small number of long-range missiles threats that employ "simple countermeasures." However, researchers with the Union of Concerned Scientists noted in a 2017 report that the only test of the GMD system against an ICBM-class target was “simplified in important ways that enhanced the test’s chance of success instead of challenging the system to work in a realistic way.”
                      • In February and April 2016, the Government Accountability Office (GAO) assessed that MDA has not “demonstrated through flight testing that it can defend the U.S. homeland against the current missile defense threat.” It did not repeat this assessment in a May 2018 report, noting the success of a May 2017 test in intercepting an ICBM-class target. 
                      • GAO also said that MDA is relying on “a highly optimistic, aggressive schedule” to upgrade the system “which has resulted in MDA: (1) accepting a proven risk of undue concurrency; (2) compromising interceptor reliability and extending risk to the warfighter; and (3) risking the efficacy of its planned flight tests in order to maintain schedule-driven deadlines necessary to meet its 2017 fielding deadline.” A May 2017 GAO report raised several red flags about the RKV program. For example, both U.S. Northern Command and U.S. Strategic Command are questioning whether the seeker planned for the kill vehicle will be able "to detect and track threats in an ICBM-range environment."

                       

                      AEGIS BALLISTIC MISSILE DEFENSE (BMD)

                      Program & Key Elements

                      • Key elements include: the RIM-161 Standard Missile-3 (SM-3), RIM-174 Standard Missile-6 (SM-6), and the Aegis combat system.
                      • The SM-3 is a hit-to-kill missile comprised of a three-stage booster with a kill vehicle. There are three variations of the SM-3 missile: Block IA, Block IB, and Block IIA. Each variation will be deployed in different phases.
                      • The SM-6 is a hit-to-kill missile based on the SM-3 but offers extended range and firepower against cruise missile targets deep inland.
                      • The Navy’s component of the missile defense system, the Aegis system is central to the defense footprint in Asia and the Phased Adaptive Approach to missile defense in Europe. Aegis is a sea-based system, with missile launchers and radars mounted on cruisers and destroyers but is adaptable to land systems as well.

                      Designed to Counter

                      • Geared toward defending against short-, medium-, and intermediate-range ballistic missiles during their midcourse phase with an emphasis on the ascent stage.

                      Status

                      • In 2005 the role of Aegis missile defense evolved from that of a forward sensor to include engagement capability.
                      • As of December 2018, the SM-3 has a test record of 40 intercepts in 49 attempts, comprising both the SM-3 and SM-6 missiles. 
                      • Japan’s four KONGO Class Destroyers have been upgraded with BMD capabilities. Japan and the United States are co-developing the SM-3 block IIA.

                      Capability / Schedule

                      • Under the FY19 budget submission, by the end of FY2019, there are scheduled to be 41 Aegis BMD ships, and by the end of FY2023, there are scheduled to be 57 Aegis BMD ships.
                      • As of October 2017, thirty-three ships are currently deployed. Of these, 17 are assigned to the Pacific Fleet and 16 to the Atlantic Fleet.
                      • A land-based SM-3 block IB deployment occurred in Romania in 2016, the same year ground was broken in Poland on a site to house land-based SM-3 IIAs. The Polish site was originally scheduled to become operational in 2018, but has been delayed until 2020.
                      • The first intercept test of the new SM-3 IIA interceptor occurred in February 2017 and was successful. However, the second and third intercept tests of the missile in June 2017 and January 2018 failed to destroy their targets. There were two more tests before the end of 2018 on Oct. 26 and Dec. 11, both successful, with the December test particularly notable for being the first successful intercept of an IRBM target and using the ability to "engage on remote" using a forward-based sensor.

                       

                      TERMINAL HIGH ALTITUDE AREA DEFENSE (THAAD)

                      Program & Key Elements

                      • Key elements include: 1) an interceptor missile comprising a single rocket booster with a separating kill-vehicle, 2) an advanced AN/TPY-2 radar unit to identify and discriminate between incoming missiles, and 3) an infrared seeker to home in on its target.
                      • The THAAD kill vehicle relies on hit-to-kill kinetic interception.
                      • THAAD batteries have four components: launcher, interceptors, radar, and fire control. Each battery can carry 48-72 interceptors (there are eight interceptors per launcher and typically each battery is believed to contain six to nine launch vehicles).
                      • THAAD missiles are fired from a truck-mounted launcher.

                      Designed to Counter

                      • THAAD’s mission is to intercept short- and medium-range ballistic missiles at the end of their midcourse stage and in the terminal stage.
                      • Intercepts could take place inside or outside the atmosphere.

                      Status

                      • As of March 2018, THAAD has succeeded in completing 15 interceptions in 15 tests since 2006. Four other THAAD tests, as of March 2018, have been classed as “no-tests.” (Note: A “no-test” occurs when the target malfunctions after launch so the interceptor is not launched.)
                      • On July 11, 2017, the U.S. Missile Defense Agency executed a successful intercept test of the THAAD system against an air-launched intermediate-range ballistic missile (IRBM) target. The test was the first against an IRBM-class target.

                      Capability / Schedule

                      • The U.S. Army operates six THAAD batteries, each with its own AN/TPY-2 radar. Three batteries, each comprising six launchers, are deployed in the Pacific: one in South Korea, one in Guam, and one in Hawaii.
                      • Production of the first THAAD interceptors began in March 2011. The Army will field 210 THAAD interceptors by September 2018, the Missile Defense Agency told Congress in June 2017, and the President requested funding for 82 additional interceptors to be built in 2019. In May 2018, GAO reported that THAAD interceptor production had been delayed, and it only delivered 41 of the planned 61 interceptors in FY2017.
                      • MDA is exploring development of an upgraded version of THAAD known as THAAD extended range, which is designed to counter ultrafast gliding weapons.
                      • The U.S. and South Korea decided in July 2016 to deploy a THAAD battery in South Korea to counter North Korean threats despite strong objections from China. The battery began operating in April 2017.
                      • A THAAD battery was deployed to Guam in 2013 to counter potential North Korea IRBM threats to the island and U.S. military assets there. The first test of the THAAD system against an IRBM target occurred in July 2017.

                       

                      PATRIOT ADVANCED CAPABILITY-3 (PAC-3)

                      Program & Key Elements

                      • Key elements include: a one-piece, hit-to-kill missile interceptor fired from a mobile launching station, which carries 16 PAC-3 missiles.
                      • The missile is guided by an independent radar that sends its tracking data to the missile through a mobile engagement control station.
                      • A blast fragmentation warhead kills the target.

                      Designed to Counter

                      • PAC-3 is designed to defend against short- and medium-range ballistic missiles in their terminal stage at lower altitudes than the THAAD system.

                      Status

                      • PAC-3s destroyed two Iraqi short-range ballistic missiles during the 2003 conflict and shot down a U.S. fighter jet. Earlier Patriot models also deployed to the region shot down nine Iraqi missiles and a British combat aircraft.

                      Capability / Schedule

                      • PAC-3 is now considered operational and has been deployed to several countries including Bahrain, Egypt, Germany, Greece, Israel, Japan, Jordan, Kuwait, the Netherlands, Saudi Arabia, South Korea, Spain, Taiwan, and the UAE.

                       

                      SPACE-BASED INFRARED SYSTEM-HIGH (SBIRS-HIGH)

                      Program Elements

                      • Key Elements: 1) geosynchronous (GEO) satellites orbiting the earth; 2) sensors on host satellites in highly elliptical earth orbit (HEO).

                      Dates Operational

                      • Primary objective is to provide early warning of theater and strategic missile launches.
                      • Provides data for technical intelligence and battle space awareness.

                      Cost

                      • Currently there are three SBIRS sensors mounted on host satellites in highly elliptical orbit (HEO-1, HEO-2, and HEO-3).
                      • There are four SBIRS satellites in geosynchronous orbit. GEO-1 was launched in May 2011, GEO-2 in March 2013, GEO-3 in January 2017, and GEO-4 in January 2018.
                      • As of March 2018, the program is projected to cost $19.6 billion for six satellites—four times greater than its initial estimated $5 billion for five satellites.

                      Major Issues

                      • The first sensor in highly elliptical orbit—HEO-1—was certified for operations by U.S. Strategic Command in December 2008.
                      • The most recent sensor, GEO-4, was launched aboard an Atlas V rocket on January 19, 2018.
                      • Lockheed Martin is under contract to produce GEO-5 and GEO-6, which will be launched in 2021 and 2022, respectively.
                      • SBIRS originally called for two additional sensors, GEO-7 and GEO-8, but these were scrapped in favor of pursuing an entirely new SBIRS follow-on program. The successor program has yet to be identified or developed. Air Force Secretary Heather Wilson suggested the new system will be "simpler" and more survivable to enemy attacks.

                       

                      RECENTLY CANCELED PROGRAMS

                      A number of high-profile missile defense efforts that began during the George W. Bush administration were canceled by President Bush’s last Defense Secretary, Robert Gates. Below is a summary of some of these programs, the reason they were canceled, and the amount of money that was spent to develop them.

                      PRECISION TRACKING SPACE SYSTEM (PTSS)
                      (Previously known as Space-based Infrared System-low (SBIRS-low))

                      Program Elements

                      The program was a planned network of 9-12 satellites which were expected to support U.S. missile defense systems by providing tracking data from space on missiles during their entire flight.

                      Dates of Program

                      October 2009 – April 2013

                      Money Spent

                      Over $230 million

                      Major Issues

                      As reported by the LA Times, outside experts found that the satellites would not have been able to detect warheads flying over the arctic. In order to provide continuous tracking of the missiles, MDA would have actually needed at least 24 satellites. An independent cost assessment projected the total cost of the system to be $24 billion over 20 years instead of the $10 billion MDA projected.

                       

                      AIRBORNE LASER (ABL)

                      Program Elements

                      The original program included a modified Boeing 747 plane equipped with a chemical oxygen-iodine laser (COIL) and two tracking lasers. The laser beam would be produced by a chemical reaction. The objective was to shoot down ballistic missiles during their boost phase right after launch but the system could also be used for other missions.

                      Dates of Program

                      November 1996 – February 2012

                      Money Spent

                      $5.3 billion

                      Major Issues

                      The laser would have had a limited range which meant the 747 would have been vulnerable to anti-aircraft missiles. To increase the range, the laser would have needed to be 20-30 times more powerful than planned.

                       

                      KINETIC ENERGY INTERCEPTOR (KEI)

                      Program Elements

                      KEI was to be comprised of three powerful boosters and a separating kill vehicle. The booster was expected to travel at least six kilometers per second, which is comparable to an ICBM. The kill vehicle was not designed to carry an explosive warhead but to destroy its target through the force of a collision.

                      Dates of Program

                      March 2003 – June 2009 

                      Money Spent

                      $1.7 billion

                      Major Issues

                      In order to carry the KEI, Navy ships would have needed to be retrofitted. The range was not great enough to be land-based.

                       

                      MULTIPLE KILL VEHICLE (MKV)

                      Program Elements

                      The program was designed to launch multiple kill vehicles from a single booster in order to increase the odds of destroying an incoming missile. It was designed to destroy both missiles and decoys.

                      Dates of Program

                      January 2004 – April 2009

                      Money Spent

                      ~$700 million

                      Major Issues

                      The program was canceled by the Obama administration in order to focus on “proven, near-term missile defense programs that can provide more immediate defenses of the United States.”

                       

                      NEXT GENERATION EFFORTS

                      The Missile Defense Agency is focusing its newest efforts to ensure the system stays ahead of developing foreign missile threats (see the below chart). Some of the advanced anti-missile technologies the Defense Department is pursuing, such as airborne lasers to zap missiles in the early stages of their flight, have been unsuccessfully pursued in the past.

                       

                      Multi-Object Kill Vehicle

                      Three defense contractors (Boeing, Lockheed Martin, and Raytheon) have been awarded contracts to develop concepts to deploy multiple kill vehicles from one booster in order to destroy decoys and multiple warheads ejected from ICBMs. MDA hopes to begin a full development program by FY 2022.

                      Boost Phase Laser Defenses

                      MDA is recommitting to research to determine how to develop laser beams that could destroy missiles in their boost phase. Inspired by the ABL program, the vision for the new system is to mate a powerful solid-state laser to drones. MDA aims to develop a laser demonstrator by 2020 or 2021 and a deployed capability by 2025.

                      Left of Launch

                      Left of launch is a proposed strategy that would be designed to counter missile threats before the missile is launched so as to reduce the need for expensive anti-missile interceptors to attempt to shoot down the missile. Tactically, the strategy would likely include the of cyber-attacks and electronic warfare to achieve this goal. Despite much speculation in the press about the U.S. ability to hack North Korean missile tests, the data shows that North Korea’s missile tests are succeeding at a high rate and that the failures are concentrated in new systems that had not been previously tested.

                      Space Tracking and Surveillance System

                      The Space Tracking and Surveillance System (STSS) is an experimental component of the U.S. ballistic missile defense architecture designed to detect and track ballistic missiles in all three phases of flight. The nascent STSS constellation orbits at 1,350km and aims to provide “launch on remote” capability—the ability to fire an interceptor before the target comes into view of a radar unit. In 2011, STSS-D demonstrated the first space-based birth-to-death tracking of a missile target.

                      Space-Based Sensor Layer

                      In August 2018, MDA Director Samuel Greaves described what the agency envisages for a future more comprehensive space sensor layer. Such a layer could look like the Air Force’s Overhead Persistent Infrared Global Scanning system, and could have a regional detection and tracking capability staring down at Earth that could go after targets that are currently harder to detect or in low earth orbit, such as hypersonic missiles, and could catch missiles in the boost or burnout phases of flight. The sensor could also cover the midcourse portion of a missile’s flight by looking against the background of space and discriminate, track, and eventually send data directly to the ballistic missile defense weapon system for fire control. Finally, the sensor could also record towards the end of a missile’s trajectory whether an intercept against a target occurred or was missed.

                       

                      CONGRESSIONAL PROPOSALS

                      In recent years Congress has sought to encourage the Obama administration to expand the U.S. ballistic missile defense effort in the face of advancing adversary ballistic missile capabilities. These initiatives, which are summarized below, have been met with strong resistance from the administration.

                      A Third National Missile Defense Site on the U.S. East Coat

                      In the fiscal year 2013 National Defense Authorization Act, Congress required the Defense Department to conduct a study to evaluate at least three possible new long-range interceptor sites that could augment the GMD system, including at least two on the East Coast. The Defense Department announced in May 2016 that it completed a draft study of three possible locations in the eastern United States for a new ballistic missile defense interceptor site, but said it had no plans to actually build such a site. The three sites are: Ft. Drum, New York; Camp Ravenna, Ohio; or Ft. Custer, Michigan. The draft environmental impact statement, which was posted on the website of the Missile Defense Agency (MDA) May 31, 2016, said that the Defense Department “does not propose and has not made a decision to deploy or construct an additional interceptor site.” The Trump administration will make a decision on whether to proceed with a third site in the MDR.

                      Space-based Missile Defense

                      The FY 2017 National Defense Authorization Act allows the Pentagon to begin design, research and development, and testing for a space-based missile defense system. The Obama administration argued that there is no requirement for a space-based intercept system and there are perennial concerns about the technical feasibility and strategic limitations of interceptors in space. However, in the 2018 National Defense Authorization Act (NDAA), Congress authorized the construction of a space-based interceptor layer, should the Missile Defense Agency deem such a system appropriate. In February 2018, Senator Ted Cruz called for funding a layer of space-based interceptors (SBI). In his testimony before the defense subcommittee of the Senate Appropriations Committee in April 2018, MDA Director Samuel Greaves said that the agency has begun “prototype design for a potential space-based missile defense architecture.” In the FY2019 National Defense Authorization Act, Congress voted to require the Defense Department to develop a space-based ballistic missile defense interceptor layer, regardless of whether the Missile Defense Review recommends such interceptors.

                      Revising the 1999 National Missile Defense Act

                      The FY 2017 National Defense Authorization Act (NDAA) revised the 1999 National Missile Defense Act to remove the world “limited,” and the 2018 NDAA authorized expansions in the national missile defense program. Proponents of the change argue that the 1999 legislation has prevented the Defense Department from adequately planning for the protection of the U.S. homeland from the full spectrum of ballistic missiles threats, including threats posed by Russia and China. The Obama administration strongly objected to the change, stating that the word “limited” is specifically intended to convey that the U.S. homeland missile defense system is designed and deployed to counter limited attacks (in number and sophistication) from Iran and North Korea, and not to counter the strategic deterrence forces of Russia and China.

                      Timeline of Nuclear Diplomacy With Iran

                      December 2018

                      Contact: Kelsey Davenport, Director for Nonproliferation Policy, (202) 463-8270 x102

                      Updated: December 2018

                      Iranian Foreign Minister Javad Zarif, U.S. Secretary of State' John Kerry, and European Union High Representativ Catherine Ashton meet Sept. 25 at the Waldorf Astoria in New York.Iran and six world powers known as the P5+1 (China, France, Germany, Russia, the United Kingdom, and the United States) reached a historic nuclear deal on July 14, 2015 that limited Iran's nuclear program and enhanced monitoring in exchange for relief from nuclear sanctions. Prior to that, Iran had been engaged in efforts to acquire the capability to build nuclear weapons for more than two decades. Although it remained uncertain whether Tehran would have made the final decision to build nuclear weapons, it had developed a range of technologies, including uranium enrichment, warhead design, and delivery systems, that would give it this option in a relatively short time frame. Tehran maintains that its nuclear activities are entirely peaceful.

                      What follows is a chronological recount of the most significant developments in Iran’s nuclear program, international efforts to negotiate a settlement to address this controversial issue, and implementation of the agreement reached by Iran and the P5+1 on July 14, 2015.

                       


                      Skip To: 1970s, 1980s, 1990s, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018

                       

                      November 1967: Iran’s first nuclear reactor, the U.S. supplied five-megawatt Tehran Research Reactor (TRR) goes critical. It operates on uranium enriched to about 93 percent (it is converted to run on 20 percent in 1993,) which the United States also supplies.

                      Take Action

                      Americans are anxious about the growing risk of a nuclear war. Adopting a policy of “no first use” would reduce the chances of war from a miscalculation or misunderstanding.

                      A nuclear war can never be won, and must never be fought.

                      Take Action Here.

                      1970s

                      February 1970: The Iranian parliament ratifies the nuclear Nonproliferation Treaty (NPT).

                      1974: Shah Reza Pahlavi establishes the Atomic Energy Organization of Iran (AEOI) and announces plans to generate about 23,000 megawatts of energy over 20 years, including the construction of 23 nuclear power plants and the development of a full nuclear fuel cycle.

                      1979: The Iranian Revolution and the seizure of the U.S. embassy in Tehran result in a severing of U.S.-Iranian ties and damages Iran’s relationship with the West. Iranian nuclear projects are halted.

                      1980s

                      January 19, 1984: The U.S. Department of State adds Iran to its list of state sponsors of terrorism, effectively imposing sweeping sanctions on Tehran.

                      1987: Iran acquires technical schematics for building a P-1 centrifuge from the Abdul Qadeer Khan network.

                      1990s

                      1992: Congress passes the Iran-Iraq Arms Nonproliferation Act of 1992, which prohibits the transfer of controlled goods or technology that might contribute “knowingly and materially” to Iran’s proliferation of advanced conventional weapons.

                      1993: Conversion of the TRR is completed by Argentina’s Applied Research Institute. It now runs on fuel enriched to just less than 20 percent, 115 kilograms of which is provided by Argentina; the contract for the conversion was signed in 1987.

                      August 5, 1996: The U.S. Congress passes the Iran-Libya Sanctions Act, also known as the Iran Sanctions Act, that penalizes foreign and U.S. investment exceeding $20 million in Iran’s energy sector in one year.

                      2002

                      August 2002: The National Council of Resistance on Iran, the political wing of the terrorist organization Mujahideen-e Khalq (MeK), holds a press conference and declares Iran has built nuclear facilities near Natanz and Arak.

                      2003

                       

                      September 12, 2003: The International Atomic Energy Agency (IAEA) Board of Governors adopts a resolution calling for Iran to suspend all enrichment – and reprocessing- related activities. The resolution requires Iran to declare all material relevant to its uranium-enrichment program and allow IAEA inspectors to conduct environmental sampling at any location. The resolution requires Iran to meet its conditions by October 31st 2003.

                      October 21, 2003: Iran agrees to meet IAEA demands by the October 31st deadline. In a deal struck between Iran and European foreign ministers, Iran agrees to suspend its uranium–enrichment activities and ratify an additional protocol requiring Iran to provide an expanded declaration of its nuclear activities and granting the IAEA broader rights of access to sites in the country.

                      2004

                      June 18, 2004: The IAEA rebukes Iran for failing to cooperate with IAEA inspectors. Iran responds by refusing to suspend enrichment-related activities as it had previously pledged.

                      November 14, 2004: Iran notifies the IAEA that it will suspend enrichment-related activities following talks with France, Germany, and the United Kingdom. According to the so-called Paris Agreement, Iran would maintain the suspension for the duration of talks among the four countries. As a result, the IAEA Board of Governors decides not to refer Tehran to the UN Security Council.

                      2005

                      February 27, 2005: Russia and Iran conclude a nuclear fuel supply agreement in which Russia would provide fuel for the Bushehr reactor it is constructing and Iran would return the spent nuclear fuel to Russia. The arrangement is aimed at preventing Iran from extracting plutonium for nuclear weapons from the spent nuclear fuel.

                      August 8, 2005: Iran begins producing uranium hexafluoride at its Isfahan facility. As a result, France, Germany, and the United Kingdom halt negotiations with Tehran.

                      September 24, 2005: The IAEA adopts a resolution finding Iran in noncompliance with its safeguards agreement by a vote of 22-1 with 12 members abstaining. The resolution says that the nature of Iran’s nuclear activities and the lack of assurance in their peaceful nature fall under the purview of the UN Security Council, paving the way for a future referral.

                      2006

                      February 4, 2006: A special meeting of the IAEA Board of Governors refers Iran to the UN Security Council. The resolution “deems it necessary for Iran to” suspend its enrichment-related activities, reconsider the construction of the Arak heavy-water reactor, ratify the additional protocol to its safeguards agreement, and fully cooperate with the agency’s investigation.

                      February 6, 2006: Iran tells the IAEA that it will stop voluntarily implementing the additional protocol and other non-legally binding inspection procedures.

                      April 11, 2006: Iran announces that it has enriched uranium for the first time. The uranium enriched to about 3.5 percent was produced at the Natanz pilot enrichment plant.

                       

                      June 6, 2006: China, France, Germany, Russia the United Kingdom, and the United Sates (the P5+1, referring to the five permanent members of the UN Security Council and Germany) propose a framework agreement to Iran offering incentives for Iran to halt its enrichment program for an indefinite period of time.

                      July 31, 2006: The UN Security Council adopts Resolution 1696, making the IAEA’s calls for Iran to suspend enrichment –related and reprocessing activities legally binding for the first time.

                      August 22, 2006: Iran delivers a response to the P5+1 proposal, rejecting the requirement to suspend enrichment but declaring that the package contained “elements which may be useful for a constructive approach.”

                      December 23, 2006: The UN Security Council unanimously adopts Resolution 1737, imposing sanctions on Iran for its failure to suspend its enrichment-related activities.

As of Feb. 12, 2018, the quantity of Iran’s uranium enriched up to 3.67% U-235 was 109.5 kg. The report notes that Iran informed the agency of its intention to pursue naval nuclear propulsion in the future.

                      March 15, 2018: State Department Director of Policy Planning Brian Hook meets with representatives from the E3 (France, Germany, and the UK) in Berlin to continue discussions on the JCPOA and Trump's demand for a 'supplemental' agreement with the Europeans that addresses sunsets, ballistic missiles, and inspections.

                      March 16, 2018: The JCPOA Joint Commission meets to oversee implementation of the agreement.

                      March 19, 2018: EU foreign policy chief Federica Mogherini says at a meeting of the Foreign Affairs Council that the EU is not considering new sanctions on Iran's ballistic missile activities, amid reports that the E3 are developing such measures.

                      April 11, 2018: Political directors from the E3 (France, Germany, and the UK) and the United States meet in Washington, DC to continue talks on Trump's demand for a supplemental agreement that addresses sunsets, ballistic missiles, and inspections. 

                      April 11, 2018: China and Iran hold a seminar on civil nuclear cooperation under the JCPOA in Beijing. 

                      April 19, 2018: 500 British, French and German parliamentarians urge U.S. members of Congress to help "keep the JCPOA alive" in a letter.

                      April 24, 2018: U.S. President Trump hosts French President Emmanuel Macron for his first state visit. Macron reports having very frank discussions with Trump about the JCPOA and said that he and President Trump had agreed to work on a "new deal" that keeps the JCPOA, but incorporates additional measures, including on Iranian ballistic missiles.

                      May 8, 2018: President Trump announces that he is withdrawing the United States from the JCPOA and signs a presidential memorandum to institute the "highest level" of economic sanctions on Iran. In a statement, Secretary of the Treasury Steve Mnuchin states that sanctions will be reimposed subject to certain 90 day and 180 day "wind-down periods." In an address following Trump's announcement Iranian President Rouhani announces that Iran will continue negotiations with the other states in the agreement in order to try to continue the deal without the United States. British Prime Minister May, German Chancellor Merkel and French President Macron re-state their continued commitment to the deal and pledge to work with all parties to make sure its terms are upheld. EU foreign policy chief Federica Mogherini states that the EU is committed to the JCPOA as long as Iran continues to implement its nuclear related commitments, as it has so far.

                      May 15, 2018: EU High Representative Federica Mogherini meets with the foreign ministers of France, Germany, and the United Kingdom, and the three European countries and Iran in two separate meetings to discuss future coordinated work following the U.S. violation of the JCPOA. They agree to "launch intensive expert discussions" to find practical solutions to the following issues in the next few weeks:

                      • "Maintaining and deepening economic relations with Iran;
                      • The continued sale of Iran's oil and gas condensate petroleum products and petrochemicals and related transfers;
                      • Effective banking transactions with Iran;
                      • Continued sea, land, air and rail transportation relations with Iran;
                      • The further provision of export credit and development of special purpose vehicles in financial banking, insurance and trade areas, with the aim of facilitating economic and financial cooperation, including by offering practical support for trade and investment;
                      • The further development and implementation of Memoranda of Understanding and contracts between European companies and Iranian counterparts;
                      • Further investments in Iran;
                      • The protection of European Union economic operators and ensuring legal certainty; 
                      • And last but not least, the further development of a transparent, rules-based business environment in Iran."

                      May 17, 2018: The European Commission meets in Sofia and announces that it will pursue a "blocking statute" to ban European companies and courts from complying with U.S. sanctions against Iran.

                      May 21, 2018: Secretary of State Mike Pompeo presents the Trump administration's new strategy on Iran after the U.S. violation of the JCPOA in a speech at the Heritage Foundation, promising to "apply unprecedented financial pressure on the Iranian regime" and work with allies to deter Iranian aggression. If the United States were to pursue a new deal, Pompeo lists 12 demands for Iran, including stopping enrichment, ending the proliferation of ballistic missiles and the development of nuclear-capable missile systems and allowing the International Atomic Energy Agency to have "unqualified access to all sites throughout the entire country." In exchange, the United States would be prepared to end "the principal components of every one of our sanctions against the regime," as well as re-establish full diplomatic and commercial relationships and allow Iran to have "advanced technology."

                      May 24, 2018: The International Atomic Energy Agency (IAEA) reports that Iran is implementing all nuclear related commitments under the JCPOA in a quarterly report. Iran’s stockpile of uranium enriched to 3.67 percent uranium-235 is 123.9 kg, below the 300 kg limit set by the accord, according to the report. The report notes that Iran is implementing the Additional Protocol but that “timely and proactive cooperation by Iran in providing such access would facilitate implementation of the Additional Protocol and enhance confidence.”

                      June 6, 2018: Iran opens a new facility for centrifuge production, an act which does not violate the JCPOA. Reza Najafi, Iran’s ambassador to the IAEA, tells press June 6 that the decision to open the facility is the “preparatory works for a possible scenario” if the JCPOA fails and reiterated that Iran will not start “any activities contrary to the JCPOA” at this time.

                      The European Commission adopts an update of the Blocking Statute to include extraterritorial sanctions that the United States re-imposed on Iran and an update of the European Investment Bank (EIB)'s External Lending Mandate to make Iran eligible for investment activities by the EIB. "These measures are meant to help protecting the interests of EU companies investing in Iran and to demonstrate the EU's commitment to the Joint Comprehensive Plan of Action (JCPOA)," reads a European Commission press release

                      July 6, 2018: The JCPOA Joint Commission meets in Vienna and releases a statement on "the way forward to ensure the continued implementation of the JCPOA in all its aspects following the withdrawal of the United States from the deal." 

                      July 16, 2018: EU foreign policy chief Federica Mogherini confirms at a press conference that the United States refused a request by France, Germany, the UK and the EU to exempt entities doing legitimate business with Iran from U.S. sanctions penalties.

                      July 18, 2018: Iran's head of the Atomic Energy Organization, Ali Akbar Salehi, announces that Iran built a new factory to produce rotors for up to 60 IR-6 centrifuges a day. Salehi says building the facility does not violate the JCPOA.

                      July 26, 2018: Ten Republican Senators write a letter to the French, German, and British ambassadors to the United States urging compliance with the sanctions reimposed by Trump and warning against efforts to block or circumvent the measures. The letter says it would be "particularly troubling if you sought to evade or undermine American statutes" and doing so "could well prompt Congressional action." 

                      August 6, 2018: In a joint statement the EU, French, German, and British foreign ministers say they "deeply regret the re-imposition of sanctions by the US" and note that they are "determined to protect European economic operators engaged in legitimate business with Iran, in accordance with EU law and with UN Security Council resolution 2231." They reiterate that preserving the JCPOA is a "matter of respecting international agreements and a matter of international security." 

                      August 7, 2018: Certain sanctions measures reimposed by Trump May 8 come into full effect. The measures include restricting Iran's purchase of U.S. dollars, trade in gold, precious metals, aluminum, steel, coal, software, and transactions related to sovereign debt and the automotive sector. Licenses allowing certain foodstuffs to be exported to the United States and Iran to purchase commercial aircraft are also revoked. 

                      August 16, 2018: Secretary of State Pompeo announces the creation of the Iran Action Group, responsible for "directing, reviewing, and coordinating all aspects" of the State Department's Iran strategy and led by Brian Hook with the title Special Representative for Iran.

                      August 22, 2018: Iran says that the UK will help with the re-design of the Arak heavy water nuclear reactor to limit the amount of plutonium byproduct it produces, a task the United States had committed to under the JCPOA.

                      Sen. Cruz (R-Texas), along with 15 republican senators, sends a letter to Treasury Secretary Mnuchin urging him to take all necessary steps to ensure the Society for Worldwide Interbank Financial Telecommunication (SWIFT) disconnects the Central Bank of Iran and all other designated Iranian financial institutions.

                      August 23, 2018: The European Commission adopts an €18 million package for Iran, the first part of a larger €50 million package, including €8 million assistance to the private sector.

                      August 27-28: The International Court of Justice hears arguments from Iran and the United States on Tehran's allegation that the U.S. reimposition of sanctions violates the 1955 U.S.-Iranian Treaty of Amity and Economic Relations. The United States contends that the court does not have jurisdiction to hear the case.

                      September 12, 2018: The International Atomic Energy Agency (IAEA) reports that Iran is implementing all nuclear-related commitments under the JCPOA in a quarterly report. Iran’s stockpile of uranium enriched to 3.67 percent uranium-235 is 139.4 kg, below the 300 kg of UF6 limit set by the accord, according to the report. Iran's stock of heavy water is 122.9 metric tons, below the 130 metric ton limit. 

                      September 24, 2018: The foreign ministers of China, France, Germany, Russia, the United Kingdom and EU foreign policy chief Federica Mogherini meet in New York to discuss the implementation of the JCPOA. The participants decide to establish a Special Purpose Vehicle "to facilitate payments related to Iran's export (including oil) and imports, which will assist and reassure economic operators pursuing legitimate business with Iran."

                      September 25, 2018: U.S. President Donald Trump speaks at the UN General Assembly in New York. "Iran’s leaders sow chaos, death, and destruction," he says, adding that many countries in the Middle East supported his decision to withdraw from the JCPOA and reimpose nuclear-related sanctions on Iran. "Additional sanctions will resume November 5th, and more will follow. And we’re working with countries that import Iranian crude oil to cut their purchases substantially.... We ask all nations to isolate Iran’s regime as long as its aggression continues. And we ask all nations to support Iran’s people as they struggle to reclaim their religious and righteous destiny."

                      On the sidelines of the UN General Assembly, U.S. Secretary of State Mike Pompeo, U.S. National Security Advisor John Bolton, U.S. Speical Representative for Iran Brian Hook, and representatives from Saudi Arabia, Yemen, Bahrain, UAE and Israel attend the United Against Nuclear Iran summit. Pompeo unveiled a new report by the State Department's Iran Action Group which chronicles "Iran's destructive activities." In his remarks, Bolton warns "there will be hell to pay" if Iran doesn't change its behavior.

                      September 26, 2018: U.S. President Donald Trump chairs a summit-level UN Security Council meeting, officially about WMD non-proliferation, but which he tweeted would be about Iran. While Trump criticizes the JCPOA in the meeting, nearly every other leader in the council expresses support for the accord and encourages Iran to continue to comply.

                      September 27, 2018: In his address to the UN General Assembly, Israeli Prime Minister Benjamin Netanyahu reveals what he describes as a secret nuclear warehouse “storing massive amounts of equipment and material from Iran’s secret nuclear weapons program.” Netanyahu also called on the International Atomic Energy Agency (IAEA) Director General Yukiya Amano to “do the right thing” and inspect the warehouse “immediately” before Iran finished clearing it out. He charged that Iran removed 15 kilograms of radioactive material from the warehouse in August, but did not specify if the material was uranium, plutonium, or another radioactive source. One intelligence official quoted in Reuters says that the facility has been known to the U.S. intelligence community for some time and it is full of documents, not nuclear equipment. The official says that “so far as anyone knows, there is nothing in it that would allow Iran to break out” of the nuclear deal any faster.

                      October 2, 2018: IAEA Director-General Yukiya Amano says in a statement that the agency does not take any information at “face value.” While Amano did not mention Netanyahu directly, he said that all material, including that received from third parties, is subject to a rigorous and independent assessment. Amano said the IAEA’s nuclear verification work “must always be impartial, factual, and professional” and that the agency’s independence is “of paramount importance.”

                      October 3, 2018: The International Court of Justice (ICJ) rules unanimously that the United States “must remove, by means of its choosing, any impediments” to the export of food, agricultural products, medicine, aircraft parts, and other humanitarian goods. The 15-member panel concludes that Trump’s decision to reimpose sanctions on Iran was unfounded given Tehran’s compliance with the JCPOA, but the court did not order the United States to remove all sanctions or compensate Iran for damages.

                      November 5, 2018: The second round of sanctions on Iran following Trump's withdrawal from the JCPOA, targeting Iran's banking, oil, shipping and ship-building sectors, come back into effect. In addition to redesignating entities removed from the SDN list under the JCPOA, United States designates an additional 300 new entities. The administration grants temporary waivers to China, India, Italy, Greece, Japan, South Korea, Taiwan and Turkey to continue importing Iranian oil at reduced levels, as well as waivers to allow nonproliferation projects at Arak, Bushehr and Fordow to continue.  

                      November 22, 2018: The International Atomic Energy Agency reports that Iran is implementing its nuclear-related committments. The IAEA's quarterly report finds that Iran's stockpile of heavy water is 122.8 metric tons, below the 130-ton limit and that Iran's stockpile of uranium enriched to 3.67 percent uranium-235 is 149.4 kilograms, below the 300-kilogram limit.

                      November 26-27, 2018: EU and Iranian officials meet in Brussels for the third High-Level Summit on International Nuclear Cooperation. The EU and Iran review past nuclear cooperation projects and discuss ongoing modifications of the Arak reactor and conversion of the Fordow facility to a research site.

                      December 12, 2018: The UN Security Council meets to discuss the biannual UN Secretary-General report on the implementation of UN Security Council Resolution 2231. The report welcomes Iran's implementation of its nuclear-related commitments "in the face of considerable challenges" from the U.S. withdrawal of the JCPOA. The report also notes Iranian activities that might violate the ballistic transfer provision in the resolution. At the meeting, U.S. Secretary of State Mike Pompeo announces that the United States will work with other UN Security Council members to reimpose on Iran the ballistic missile restrictions outlined in UN Security Council Resolution 1929.

                      The Intermediate-Range Nuclear Forces (INF) Treaty at a Glance

                      History of the INF Treaty between the United States and Russia and details on potential violations by Russia

                      Contact: Daryl Kimball, Executive Director, (202) 463-8270 x107; Kingston Reif, Director for Disarmament and Threat Reduction Policy, (202) 463-8270 x104

                      Updated: December 2018

                      The 1987 Intermediate-Range Nuclear Forces (INF) Treaty required the United States and the Soviet Union to eliminate and permanently forswear all of their nuclear and conventional ground-launched ballistic and cruise missiles with ranges of 500 to 5,500 kilometers. The treaty marked the first time the superpowers had agreed to reduce their nuclear arsenals, eliminate an entire category of nuclear weapons, and utilize extensive on-site inspections for verification. As a result of the INF Treaty, the United States and the Soviet Union destroyed a total of 2,692 short-, medium-, and intermediate-range missiles by the treaty's implementation deadline of June 1, 1991.

                      The United States first alleged in its July 2014 Compliance Report that Russia is in violation of its INF Treaty obligations “not to possess, produce, or flight-test” a ground-launched cruise missile having a range of 500 to 5,500 kilometers or “to possess or produce launchers of such missiles.” Subsequent State Department assessments in 2015, 2016, 2017, and 2018 repeated these allegations. In March 2017, a top U.S. official confirmed press reports that Russia had begun deploying the noncompliant missile. Russia denies that it is in violation of the agreement and has accused the United States of being in noncompliance.

                      On Dec. 8, 2017, the Trump administration released an integrated strategy to counter alleged Russian violations of the Treaty, including the commencement of research and development on a conventional, road-mobile, intermediate-range missile system. On Oct. 20, 2018 President Donald Trump announced his intention to “terminate” the INF Treaty, citing Russian noncompliance and concerns about China’s intermediate-range missile arsenal. On Dec. 4, 2018 Secretary of State Mike Pompeo announced that the United States has found Russia in “material breach” of the treaty and will suspend its treaty obligations in 60 days if Russia does not return to compliance in that time.

                      History

                      U.S. calls for the control of intermediate-range missiles emerged as a result of the Soviet Union's domestic deployment of SS-20 intermediate-range missiles in the mid-1970s. The SS-20 qualitatively improved Soviet nuclear forces in the European theater by providing a longer-range, multiple-warhead alternative to aging Soviet SS-4 and SS-5 single-warhead missiles. In 1979, NATO ministers responded to the new Soviet missile deployment with what became known as the "dual-track" strategy—a simultaneous push for arms control negotiations with the deployment of intermediate-range, nuclear-armed U.S. missiles (ground-launched cruise missiles and the Pershing II) in Europe to offset the SS-20. Negotiations, however, faltered repeatedly while U.S. missile deployments continued in the early 1980s.

                      INF Treaty negotiations began to show progress once Mikhail Gorbachev became the Soviet general-secretary in March 1985. In the fall of the same year, the Soviet Union put forward a plan to establish a balance between the number of SS-20 warheads and the growing number of allied intermediate-range missile warheads in Europe. The United States expressed interest in the Soviet proposal, and the scope of the negotiations expanded in 1986 to include all U.S. and Soviet intermediate-range missiles around the world. Using the momentum from these talks, President Ronald Reagan and Gorbachev began to move toward a comprehensive intermediate-range missile elimination agreement. Their efforts culminated in the signing of the INF Treaty on Dec. 8, 1987, and the treaty entered into force on June 1, 1988.

                      The intermediate-range missile ban originally applied only to U.S. and Soviet forces, but the treaty's membership expanded in 1991 to include successor states of the former Soviet Union. Today, Belarus, Kazakhstan, and Ukraine, which had inspectable facilities on their territories at the time of the Soviet Union’s dissolution, join Russia and the United States in the treaty's implementation. Turkmenistan and Uzbekistan also possessed INF Treaty-range facilities (SS-23 operating bases) but forgo treaty meetings with the consent of the other states-parties.

                      Although active states-parties to the treaty total just five countries, several European countries have destroyed INF Treaty-range missiles since the end of the Cold War. Germany, Hungary, Poland, and the Czech Republic destroyed their intermediate-range missiles in the 1990s, and Slovakia dismantled all of its remaining intermediate-range missiles in October 2000 after extensive U.S. prodding. On May 31, 2002, the last possessor of intermediate-range missiles in eastern Europe, Bulgaria, signed an agreement with the United States to destroy all of its INF Treaty-relevant missiles. Bulgaria completed the destruction five months later with U.S. funding.

                      States-parties' rights to conduct on-site inspections under the treaty ended on May 31, 2001, but the use of surveillance satellites for data collection continues. The INF Treaty established the Special Verification Commission (SVC) to act as an implementing body for the treaty, resolving questions of compliance and agreeing on measures to "improve [the treaty's] viability and effectiveness." Because the INF Treaty is of unlimited duration, states-parties can convene the SVC at any time, and the commission continues to meet today. The most recent SVC session, called by the United States, took place December 12-14, 2017 and was also attended by Russia, Belarus, Kazakhstan, and Ukraine.

                      Elimination Protocol

                      The INF Treaty's protocol on missile elimination named the specific types of ground-launched missiles to be destroyed and the acceptable means of doing so. Under the treaty, the United States committed to eliminate its Pershing II, Pershing IA, and Pershing IB ballistic missiles and BGM-109G cruise missiles. The Soviet Union had to destroy its SS-20, SS-4, SS-5, SS-12, and SS-23 ballistic missiles and SSC-X-4 cruise missiles. In addition, both parties were obliged to destroy all INF Treaty-related training missiles, rocket stages, launch canisters, and launchers. Most missiles were eliminated either by exploding them while they were unarmed and burning their stages or by cutting the missiles in half and severing their wings and tail sections.

                      Inspection and Verification Protocols

                      The INF Treaty's inspection protocol required states-parties to inspect and inventory each other's intermediate-range nuclear forces 30 to 90 days after the treaty's entry into force. Referred to as "baseline inspections," these exchanges laid the groundwork for future missile elimination by providing information on the size and location of U.S. and Soviet forces. Treaty provisions also allowed signatories to conduct up to 20 short-notice inspections per year at designated sites during the first three years of treaty implementation and to monitor specified missile-production facilities to guarantee that no new missiles were being produced.

                      The INF Treaty's verification protocol certified reductions through a combination of national technical means (i.e., satellite observation) and on-site inspections-a process by which each party could send observers to monitor the other's elimination efforts as they occurred. The protocol explicitly banned interference with photo-reconnaissance satellites, and states-parties were forbidden from concealing their missiles to impede verification activities. Both states-parties could carry out on-site inspections at each other's facilities in the United States and Soviet Union and at specified bases in Belgium, Italy, the Netherlands, the United Kingdom, West Germany, and Czechoslovakia.

                      The INF Treaty’s Slow Demise

                      Since the mid-2000s, Russia has raised the possibility of withdrawing from the INF Treaty. Moscow contends that the treaty unfairly prevents it from possessing weapons that its neighbors, such as China, are developing and fielding. Russia also has suggested that the proposed U.S. deployment of strategic anti-ballistic missile systems in Europe might trigger a Russian withdrawal from the accord, presumably so Moscow can deploy missiles targeting any future U.S. anti-missile sites. Still, the United States and Russia issued an October 25, 2007, statement at the United Nations General Assembly reaffirming their “support” for the treaty and calling on all other states to join them in renouncing the missiles banned by the treaty.

                      Reports began to emerge in 2013 and 2014 that the United States had concerns about Russia's compliance with the INF Treaty. In July 2014, the U.S. State Department found Russia to be in violation of the agreement by producing and testing an illegal ground-launched cruise missile. Russia responded in August refuting the claim, and continues to maintain that it is not in violation of the INF Treaty. Throughout 2015 and most of 2016, U.S. Defense and State Department officials had publicly expressed skepticism that the Russian cruise missiles at issue had been deployed. But an Oct. 19, 2016 report in The New York Times cited anonymous U.S. officials who were concerned that Russia was producing more missiles than needed solely for flight testing, which increased fears that Moscow was on the verge of deploying the missile. By Feb. 14, 2017, The New York Times cited U.S. officials declaring that Russia had deployed an operational unit of the treaty-noncompliant cruise missile now known as the SSC-8. On March 8, 2017, General Paul Selva, the vice chairman of the U.S. Joint Chiefs of Staff, confirmed press reports that Russia had deployed a ground-launched cruise missile that “violates the spirit and intent” of the INF Treaty.

                      The State Department’s 2017 annual assessment of Russian compliance with key arms control agreements alleged Russian noncompliance with the INF Treaty for the fourth consecutive year, and also listed new details on the steps Washington took in 2016 to resolve the dispute, including convening a session of the SVC, and providing Moscow with further information on the violation.

                      The report says the missile in dispute is distinct from two other Russian missile systems, the R-500/SSC-7 Iskander GLCM and the RS-26 ballistic missile. The R-500 has a Russian-declared range below the 500-kilometer INF Treaty cutoff, and Russia identifies the RS-26 as an intercontinental ballistic missile treated in accordance with the New Strategic Arms Reduction Treaty (New START). The report also appears to suggest that the launcher for the allegedly noncompliant missile is different from the launcher for the Iskander. In late 2017 the United States for the first time revealed both the U.S. name for the missile of concern, the SSC-8, and the apparent Russian designation, the 9M729.

                      Russia denies that it is breaching the agreement and has raised its own concerns about Washington’s compliance. Moscow is charging that the United States is placing a missile defense launch system in Europe that can also be used to fire cruise missiles, using targets for missile defense tests with similar characteristics to INF Treaty-prohibited intermediate-range missiles, and making armed drones that are equivalent to ground-launched cruise missiles.

                      Congress for the past several years has urged a more assertive military and economic response to Russia’s violation. The fiscal year 2018 National Defense Authorization Act (NDAA) authorized funds for the Defense Department to develop a conventional, road-mobile, ground-launched cruise missile that, if tested, would violate the treaty. The fiscal year 2019 NDAA also included provisions on the treaty. Section 1243 states that no later than Jan. 15, 2019, the President would submit to Congress a determination on whether Russia is “in material breach” of its INF Treaty obligations and whether the “prohibitions set forth in Article VI of the INF Treaty remain binding on the United States.” Section 1244 expresses the sense of Congress that in light of Russia’s violation of the treaty, that the United States is “legally entitled to suspend the operation of the INF Treaty in whole or in part” as long as Russia is in material breach.

                      On Dec. 8, 2017 the Trump administration announced a strategy to respond to alleged Russian violations, which comprised of three elements: diplomacy, including through the Special Verification Commission, research and development on a new conventional ground-launched cruise missile, and punitive economic measures against companies believed to be involved in the development of the missile.

                      However, President Trump announced Oct. 20 that he would “terminate” the INF Treaty in response to the long-running dispute over Russian noncompliance with the agreement, as well as citing concerns about China’s unconstrained arsenal of INF Treaty-range missiles. Trump’s announcement seemed to take NATO allies by surprise, with many expressing concern about the president's plan. 

                      After repeatedly denying the existence of the 9M729 cruise missile, Russia has since acknowledged the missile but continues to deny that the missile has been tested or is able to fly at an INF Treaty-range.

                      On Nov. 30, U.S. Director of National Intelligence Daniel Coats provided further details on the Russian treaty violation. Coats revealed that the United States believes Russia cheated by conducting legally allowable tests of the 9M729, such as testing the missile at over 500 km from a fixed launcher (allowed if the missile is to be deployed by air or sea), as well as testing the same missile from a mobile launcher at a range under 500 km. Coats noted that “by putting the two types of tests together” Russia was able to develop an intermediate-range missile that could be launched from a “ground-mobile platform,” in violation of the treaty.

                      On Dec. 4, Secretary of State Mike Pompeo announced that the United States has found Russia in “material breach” of the treaty and will suspend its treaty obligations in 60 days if Russia does not return to compliance in that time. The official notice of the United States’ intent to withdraw would begin a six-month withdrawal period as allowed by the treaty. Though NATO allies in a Dec. 4 statement expressed for the first time the conclusion that Russia had violated the INF Treaty, the statement notably did not comment on Pompeo's ultimatum.

                      Russian President Vladimir Putin responded Dec. 5 by noting that Russia would respond “accordingly” to U.S. withdrawal from the treaty, and the chief of staff of the Russian military General Valery Gerasimov noted that U.S. missile sites on allied territory could become “targets of subsequent military exchanges." On Dec. 14, Reuters reported that Russian foreign ministry official Vladimir Yermakov was cited by RIA news agency as saying that Russia is ready to discuss mutual inspections with the United States in order to salvage the treaty.

                      Updated: December 2018

                      Over the past four decades, American and Soviet/Russian leaders have used a progression of bilateral agreements and other measures to limit and reduce their substantial nuclear warhead and strategic missile and bomber arsenals. The following is a brief summary.

                      Strategic Nuclear Arms Control Agreements

                      SALT I

                      Begun in November 1969, by May 1972, the Strategic Arms Limitation Talks (SALT) had produced both the Anti-Ballistic Missile (ABM) Treaty, which limited strategic missile defenses to 200 (later 100) interceptors each, and the Interim Agreement, an executive agreement that capped U.S. and Soviet intercontinental ballistic missiles (ICBM) and submarine-launched ballistic missile (SLBM) forces. Under the Interim Agreement, both sides pledged not to construct new ICBM silos, not to increase the size of existing ICBM silos “significantly,” and capped the number of SLBM launch tubes and SLBM-carrying submarines. The agreement ignored strategic bombers and did not address warhead numbers, leaving both sides free to enlarge their forces by deploying multiple warheads (MIRVs) onto their ICBMs and SLBMs and increasing their bomber-based forces. The agreement limited the United States to 1,054 ICBM silos and 656 SLBM launch tubes. The Soviet Union was limited to 1,607 ICBM silos and 740 SLBM launch tubes. In June 2002, the United States unilaterally withdrew from the ABM treaty.

                      SALT II

                      In November 1972, Washington and Moscow agreed to pursue a follow-on treaty to SALT I. SALT II, signed in June 1979, limited U.S. and Soviet ICBM, SLBM, and strategic bomber-based nuclear forces to 2,250 delivery vehicles (defined as an ICBM silo, a SLBM launch tube, or a heavy bomber) and placed a variety of other restrictions on deployed strategic nuclear forces. The agreement would have required the Soviets to reduce their forces by roughly 270 delivery vehicles, but U.S. forces were below the limits and could actually have been increased. However, President Jimmy Carter asked the Senate not to consider SALT II for its advice and consent after the Soviet Union invaded Afghanistan in December 1979, and the treaty was not taken up again. Both Washington and Moscow subsequently pledged to adhere to the agreement’s terms despite its failure to enter into force. However, on May 26, 1986, President Ronald Reagan said that future decisions on strategic nuclear forces would be based on the threat posed by Soviet forces and not on "a flawed SALT II Treaty.”

                      START I

                      The Strategic Arms Reduction Treaty (START I), first proposed in the early 1980s by President Ronald Reagan and finally signed in July 1991, required the United States and the Soviet Union to reduce their deployed strategic arsenals to 1,600 delivery vehicles, carrying no more than 6,000 warheads as counted using the agreement’s rules. The agreement required the destruction of excess delivery vehicles which was verified using an intrusive verification regime that involved on-site inspections, the regular exchange of information, including telemetry, and the use of national technical means (i.e., satellites). The agreement’s entry into force was delayed for several years because of the collapse of the Soviet Union and ensuing efforts to denuclearize Ukraine, Kazakhstan, and Belarus by returning their nuclear weapons to Russia and making them parties to the nuclear Nonproliferation Treaty (NPT) and START I agreements. START I reductions were completed in December 2001 and the treaty expired on Dec. 5, 2009.

                      START II

                      In June 1992, Presidents George H. W. Bush and Boris Yeltsin agreed to pursue a follow-on accord to START I. START II, signed in January 1993, called for reducing deployed strategic arsenals to 3,000-3,500 warheads and banned the deployment of destabilizing multiple-warhead land-based missiles. START II would have counted warheads in roughly the same fashion as START I and, also like its predecessor, would have required the destruction of delivery vehicles but not warheads. The agreement's original implementation deadline was January 2003, ten years after signature, but a 1997 protocol moved this deadline to December 2007 because of the extended delay in ratification. Both the Senate and the Duma approved START II, but the treaty did not take effect because the Senate did not ratify the 1997 protocol and several ABM Treaty amendments, whose passage the Duma established as a condition for START II’s entry into force. START II was effectively shelved as a result of the 2002 U.S. withdrawal from the ABM treaty.

                      START III Framework

                      In March 1997, Presidents Bill Clinton and Boris Yeltsin agreed to a framework for START III negotiations that included a reduction in deployed strategic warheads to 2,000-2,500. Significantly, in addition to requiring the destruction of delivery vehicles, START III negotiations were to address “the destruction of strategic nuclear warheads…to promote the irreversibility of deep reductions including prevention of a rapid increase in the number of warheads.” Negotiations were supposed to begin after START II entered into force, which never happened.

                      SORT (Moscow Treaty)

                      On May 24, 2002, Presidents George W. Bush and Vladimir Putin signed the Strategic Offensive Reductions Treaty (SORT or Moscow Treaty) under which the United States and Russia reduced their strategic arsenals to 1,700-2,200 warheads each. The warhead limit took effect and expired on the same day, Dec. 31, 2012. Although the two sides did not agree on specific counting rules, the Bush administration asserted that the United States would reduce only warheads deployed on strategic delivery vehicles in active service, i.e., “operationally deployed” warheads, and would not count warheads removed from service and placed in storage or warheads on delivery vehicles undergoing overhaul or repair. The agreement’s limits are similar to those envisioned for START III, but the treaty did not require the destruction of delivery vehicles, as START I and II did, or the destruction of warheads, as had been envisioned for START III. The treaty was approved by the Senate and Duma and entered into force on June 1, 2003. SORT was replaced by New START on February 5, 2011.

                      New START

                      On April 8, 2010, the United States and Russia signed New START, a legally binding, verifiable agreement that limits each side to 1,550 strategic nuclear warheads deployed on 700 strategic delivery systems (ICBMs, SLBMs and heavy bombers), and limits deployed and nondeployed launchers to 800. The treaty-accountable warhead limit is 30 percent lower than the 2,200 upper limit of SORT, and the delivery vehicle limit is 50 percent lower than the 1,600 allowed in START I. The treaty has a verification regime that combines elements of START I with new elements tailored to New START. Measures under the treaty include on-site inspections and exhibitions, data exchanges and notifications related to strategic offensive arms and facilities covered by the treaty, and provisions to facilitate the use of national technical means for treaty monitoring. The treaty also provides for the continued exchange of telemetry (missile flight-test data on up to five tests per year) and does not meaningfully limit missile defenses or long-range conventional strike capabilities. The U.S. Senate approved New START on Dec. 22, 2010. The approval process of the Russian parliament (passage by both the State Duma and Federation Council) was completed Jan. 26, 2011. The treaty entered into force on Feb. 5, 2011 and will expire in 2021, though both parties may agree to extend the treaty for a period of up to five years. Both parties met the treaty’s central limits by the Feb. 4, 2018 deadline for implementation.

                      Nonstrategic Nuclear Arms Control Measures

                      Intermediate-Range Nuclear Forces (INF) Treaty

                      Signed Dec. 8, 1987, the INF Treaty required the United States and the Soviet Union to verifiably eliminate all ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. Distinguished by its unprecedented, intrusive inspection regime, including on-site inspections, the INF Treaty laid the groundwork for verification of the subsequent START I. The INF Treaty entered into force June 1, 1988, and the two sides completed their reductions by June 1, 1991, destroying a total of 2,692 missiles. The agreement was multilateralized after the breakup of the Soviet Union, and current active participants in the agreement include the United States, Russia, Belarus, Kazakhstan, and Ukraine. Turkmenistan and Uzbekistan are also parties to the agreement but do not participate in treaty meetings or on-site inspections. The ban on intermediate-range missiles is of unlimited duration.

                      Both the United States and Russia have raised concerns about the other side’s compliance with the INF Treaty. The United States first publicly charged Russia with developing and testing a ground-launched cruise with a range that meets the INF Treaty definition of a ground-launched cruise missile with a range capability of 500 km to 5,500 km in 2014.

                      Russia denies that it is breaching the agreement and has raised its own concerns about Washington’s compliance. Moscow is charging that the United States is placing a missile defense launch system in Europe that can also be used to fire cruise missiles, using targets for missile defense tests with similar characteristics to INF Treaty-prohibited intermediate-range missiles, and is making armed drones that are equivalent to ground-launched cruise missiles. On Oct. 20, 2018 President Donald Trump announced his intention to “terminate” the agreement citing Russian noncompliance and concerns about China’s missiles, and on Dec. 4, Secretary of State Mike Pompeo declared Russia in “material breach” of the treaty and began a 60-day countdown for Russia to return to compliance before the United States would suspend its implementation of the treaty and officially notify the treaty parties of its intent to withdraw. Per the treaty’s terms, the U.S. withdrawal would formally take effect six-months after the notification.

                      Presidential Nuclear Initiatives 

                      On Sept. 27, 1991, President George H. W. Bush announced that the United States would remove almost all U.S. tactical (nonstrategic) nuclear forces from deployment so that Russia could undertake similar actions, reducing the risk of nuclear proliferation as the Soviet Union dissolved. Specifically, Bush said the United States would eliminate all its nuclear artillery shells and short-range nuclear ballistic missile warheads and remove all nonstrategic nuclear warheads from surface ships, attack submarines, and land-based naval aircraft. Soviet leader Mikhail Gorbachev reciprocated on Oct. 5, pledging to eliminate all nuclear artillery munitions, nuclear warheads for tactical missiles, and nuclear landmines. He also pledged to withdraw all Soviet tactical naval nuclear weapons from deployment. Under these initiatives, the United States and Russia reduced their deployed nonstrategic stockpiles by an estimated 5,000 and 13,000 warheads, respectively. However, significant questions remain about Russian implementation of its pledges, and there is considerable uncertainty about the current state of Russia’s tactical nuclear forces. The Defense Department estimates that Russia possess roughly 2,000 non-strategic nuclear weapons and the numbers are expanding. The United States maintains several hundred nonstrategic B61 gravity bombs for delivery by short-range fighter aircraft.

                      WMD-Free Middle East Proposal at a Glance

                      December 2018

                      Contact: Kelsey Davenport, Director for Nonproliferation Policy, (202) 463-8270 x102

                      Updated: December 2018

                      As part of a package of decisions that resulted in the indefinite extension of the nuclear Nonproliferation Treaty (NPT), the 1995 NPT Review Conference called for “the establishment of an effectively verifiable Middle East zone free of weapons of mass destruction, nuclear, chemical and biological, and their delivery systems.” First put forth by Egypt in 1990, the Weapons of Mass Destruction-Free Zone (WMDFZ) proposal expanded on longstanding calls to establish a Nuclear Weapons-Free Zone (NWFZ) in the Middle East. Both measures, intended to be pursued in parallel, have garnered broad international support but practical progress has since been elusive.

                      Background

                      The United Nations General Assembly (UNGA) first endorsed calls for the establishment of a NWFZ in a resolution approved in December of 1974 following a proposal by Iran and Egypt. From 1980 to 2018, that resolution had been passed annually without a vote by UNGA and endorsement for the proposal has been incorporated in a number of UN Security Council Resolutions. In 2018, the resolution was brought to a vote with the United States and Israel voting against. From 1991 onwards the IAEA General Conference has also adopted annually without objections a resolution calling for the application of full scope safeguards on all nuclear facilities in the region “as a necessary step for the establishment of the NWFZ.”

                      Prompted by Egypt in 1988, the UN Secretary General undertook a “Study on Effective and Verifiable Measures which Would Facilitate the Establishment of a Nuclear Weapons Free Zone in the Middle East” that looked at conditions surrounding the creation of NWFZ and made a number recommendations including a list confidence building measures. A 1989 IAEA Technical Study also looked at various modalities for the application of safeguards on nuclear facilities in the Middle East as a necessary step to establishing a NWFZ.

                      Despite extensive international support and the catalogue of resolutions endorsed including by all regional states, practical progress has been stymied by sharp disagreements between countries in the region over the terms and the sequence of steps leading to the establishment of the zone. Reflecting differing perceptions of threat and security concerns existing in the region, Israel has closely linked discussions on the establishment of the WMDFZ with the existence of durable peace and compliance with international obligations by states in the region. Arab states have said that no such linkage should exist and that the establishment of WMDFZ would contribute to peaceful relations.

                      Basic Elements of the Middle East WMDFZ

                      A future WMDFZ would commit parties not to possess, acquire, test, manufacture or use any nuclear, chemical and biological weapons as well as their delivery systems as provided for in the 1995 NPT Review Conference Middle East resolution. Definitions for what constitutes these types of non-conventional weapons are contained in international treaties on nuclear, chemical and biological weapons, as well as the 1948 United Nations Commission for Conventional Armaments. A shared understanding would also be required to regulate the types of delivery systems that would become subject to the prohibitions under the zone. Discussions have included proposals for banning all ballistic missiles with ranges in excess of 150 km.

                      Territory: The 1989 IAEA Technical Study, which first took up the geographic delimitation of a future Middle East NWFZ, applied the concept to a region extending from Libya in the west, to Iran in the east, and from Syria in the north to Yemen in the south. A subsequent UN Study expanded the concept further by including all League of Arab states, plus Iran and Israel in the zone. The Arab League has officially endorsed the UN Study delimitation and Israel has raised no objection other than note that any country in the region should be publicly recognized and accepted as an integral part thereof. Suggestions of including Afghanistan, Pakistan as well as Turkey in the eventual zone have not gained any significant traction.

                      Verification: One of the principles recognized by UNGA Resolution 3472B on NWFZs in 1975 was that such a zone “should provide for effective verification of compliance with the commitments made by the parties to the Treaty.” Israel has long insisted that any future WMDFZ must also provide “for mutual verification measures” while other proposals have included calls for setting up a regional organization to ensure compliance.

                      The WMD-Free Zone in the Middle East: 2010 - present

                      At the 2010 NPT Review Conference, state parties were able to agree for the first time to five practical steps to make progress towards implementing the 1995 NPT Review Conference Middle East resolution. The United States, Russia and the United Kingdom, the treaty depository powers and sponsors of that Resolution, committed to work together with the UN Secretary General to convene a regional conference to discuss the issue in 2012. Other measures agreed included the appointment of a WMDFZ facilitator as well as designation of a government that will host the conference. 

                      The European Union has also offered to host a seminar, a follow-up on the one organized in Paris in 2008, to discuss steps that would facilitate work on establishing the Free Zone ahead of 2012 Conference.

                      In November 2011, a two-day meeting was held at the IAEA headquarters. Proposals by 97 participating nations included:

                      • to continue working towards the establishment of a NWFZ in the Middle East;
                      • to consider declarations of good intentions as a first step to break the current stalemate;
                      • to make the best and most constructive use of every opportunity on the international agenda; and
                      • to identify specific and practical confidence-building measures.

                      The regional conference on the establishment of a WMD free zone in the Middle East proposed by the NPT was set to be held in Finland in December 2012, and Finnish Undersecretary of State Jaakko Laajava was name as the facilitator.

                      On November 23, the United States issued a statement postponing the December 2012 conference. The conference has not yet been rescheduled, and the co-conveners are offering different opinions as to when it should be held, and the reasons for the delay. The U.S. statement cited "present conditions in the Middle East" and the lack of agreement by participating states on "acceptable conditions" for the December conference. No timeline for rescheduling was included. In a November 24 statement, Russia called for the conference to be held before April 2013, citing that the preparations had already reached an "advanced stage" and that the reason for postponement was that not all states in the region agreed to participate in the conference. At the time of the announcement, conference facilitator Jaakko Laajava, had not yet secured Israel's attendance. While Iran announced that it would attend on November 7, it also said it would not engage with the Israelis at the conference, and some experts believe Iran only announced it would attend because Tehran knew that the December 2012 meeting would not take place.

                      On April 29, 2013, Egypt walked out of the NPT Preparatory Committee Meeting in Geneva in protest of the conference's postponement and called for it to be rescheduled as soon as possible.

                      Between October 2013 and June 2014, Laajava, with the support of the conveners, has held five consultations with the countries in the region aimed at reaching consensus on an agenda for the conference. The last consultation was held in June 2014. The Arab League member states and Israel have attended every meeting. Iran was present only at the first consultation in October 2013, but is regularly briefed on the outcomes of the consultations.

                      During the 2015 NPT Review Conference, Egypt led the Arab League in pushing a new proposal to dispense with the facilitator and three of the conveners (Russia, the United Kingdom and the United States), leaving the UN Secretary General as the sole authority for holding the conference within 180 days of the Review Conference ending. The Egyptian proposal also called for the creation of two working groups. Working Group I would deal with the scope, geographic demarcation, prohibitions and interim measures. Working Group II would deal with verification measures and implementation mechanisms.

                      A modified version of the Egyptian proposal appeared in the draft final document of the 2015 NPT Review Conference. The draft final document called for the UN secretary-general to convene a conference by March 1, 2016, aimed at “launching a continuous process of negotiating and concluding a legally binding treaty” that establishes a WMD-free zone in the Middle East.

                      The document called for the secretary-general to appoint by July 1 a special representative to facilitate the process. The facilitator would work with the secretary-general, as well as Russia, the UK, and the United States, to consult with the states in the region on the agenda for the conference.

                      Under the language in the draft document, if an agenda for the conference were agreed before the March deadline, the secretary-general would have to convene the conference within 45 days of agreement on the agenda.

                      The United States, the United Kingdom and Canada decided not to support the draft final document from the NPT review conference based on the language concerning the Middle East WMD-free zone. The United States, speaking at the conference, said it objected because the plan to set an agenda and hold a conference was not based on "consensus and equality," and that the document proposed "unworkable conditions" and "arbitrary deadlines."

                      The WMD-free zone in the Middle East initiative continued to be a key discussion topic at the first NPT preparatory committee meeting in 2017 leading up to the 2020 Review Conference. The Arab League did not present a unified statement on the issue, marking a growing divide among members on the subject. Instead, Egypt, Iran, and a group of 12 Arab League members, including Iraq and the United Arab Emirates, each offered separate working papers on advancing the WMD-free zone in the Middle East.

                      In 2018, the UN First Committee adopted a resolution introduced by Egypt on behalf of the Arab League for the UN secretary-general to convene a conference on taking forward a WMD-free zone in the Middle East in 2019 and every year thereafter until a zone is achieved. Israel, Micronesia and the United States voted against the resolution and 71 countries abstained.

                      Updated: November 2018

                      In July 2012, Syria publicly acknowledged that it possesses chemical weapons. For a number of years preceding this announcement, the U.S. intelligence community assessed that Syria has a stockpile of chemical weapons, including blister agents such as mustard gas, and nerve agents such as sarin and VX. Syria has the capability to deliver these agents using aerial bombs, ballistic missiles, and artillery rockets. An Organisation for the Prohibition of Chemical Weapons-UN joint investigative team found Syria and the Islamic State responsible for numerous chemical weapons attacks in Syria over the past several years.

                      Below is a timeline of significant events related to Syria’s chemical weapons program from July 2012 to the present.

                      Skip to: 2012, 2013, 2014, 2015, 2016, 2017, 2018

                      Take Action

                      Americans are anxious about the growing risk of a nuclear war. Adopting a policy of “no first use” would reduce the chances of war from a miscalculation or misunderstanding.

                      A nuclear war can never be won, and must never be fought.

                      Take Action Here.

                      2012

                      July 23, 2012: Syrian Foreign Ministry spokesman Jihad Makdissi confirmed for the first time that Syria has chemical weapons, stating that these weapons would never be used against the Syrian people, but only against “external aggression.”

                      August 20, 2012: President Barack Obama articulated his red-line regarding the use of chemical weapons in Syria. Obama said his calculations on a military response would change significantly if the United States sees “a whole bunch of chemical weapons moving around or being utilized.”

                      August 23, 2012: An official in the State Department confirmed that “Syria has a stockpile composed of nerve agents and mustard gas” and that the U.S. government monitors Syria’s chemical weapons activities “very closely.”

                      December 23, 2012: The first allegation of  chemical weapons use was reported. Seven people were allegedly killed in Homs by a “poisonous gas” used by the Assad regime. The coverage included the report of side effects such as nausea, relaxed muscles, blurred vision, and breathing difficulties.

                      2013

                      January 15, 2013: A secret State Department cable from the U.S. consul general in Istanbul said there was compelling evidence that the Syrian military had used a chemical weapon known as Agent 15 in Homs on December 23, 2012.

                      January 16, 2013: Tommy Vietor, a spokesman for the National Security Council, said that the alleged incident of chemical weapons use in December was not consistent with information that the White House has about Syria’s chemical weapons program.

                      March 19, 2013: Alleged chemical weapons attacks were reported in Syria’s two main cities, the Khan al-Assel neighborhood of Aleppo and the Damascus suburb of al-Atebeh. About 25 people reportedly were killed and dozens more injured. The Assad regime claimed that Syrian opposition forces used chemical weapons in the fighting there.

                      March 20, 2013: The Syrian government requested the United Nations conduct an investigation of the March 19 attack on Aleppo, claiming that opposition forces used chemical weapons and killed 25 people.

                      President Obama said in a press conference with Israeli Prime Minister Netanyahu that “the use of chemical weapons is a game changer,” in Syria.

                      March 21, 2013: UN Secretary-General Ban Ki-moon announced the United Nations will conduct an investigation on the possible use of chemical weapons in Syria, in conjunction with the World Health Organization (WHO) and the Organisation for the Prohibition of Chemical Weapons (OPCW). Prior to the announcement, France and the United Kingdom sent letters to the Secretary-General, calling for investigations into three alleged incidents of the use of chemical weapons in Syria.

                      March 24, 2013: Syrian opposition activists reported that Syrian forces used chemical weapons from multiple rocket launchers at the town of Adra, northeast of Damascus, alleging two deaths and 23 injuries. Doctors described that the weapons used were phosphorus bombs that harm the nervous system and induce imbalance and loss of consciousness.

                      April 13, 2013: Syrian Observatory for Human Rights (SOHR) said that the Syrian army dropped two gas bombs on rebel-controlled Aleppo, killing two people and wounding 12. Opponents of the Syrian government accused the army of using chemical weapons.

                      April 17, 2013: UN Secretary-General Ban Ki-moon stated that Syria has impeded the UN investigation by failing to agree to the scope of the UN inquiry on chemical weapons use.

                      April 25, 2013: A letter sent to Sens. Carl Levin (D-Mich.) and John McCain (R-Ariz.) from the U.S. intelligence community said that the Assad regime may have used the nerve agent sarin “on a small scale” in Syria, but that the United States needs more evidence to provide “some degree of certainty” for any decision-making on further action. The letter also said that the Assad regime maintains custody of the chemical weapons in Syria.

                      April 26, 2013: President Obama remarked that the United States and the international community will work together to gain “strong evidence” of the Assad regime’s use of chemical weapons.

                      April 29, 2013: A helicopter dropped canisters allegedly containing chemical weapons on the town of Saraqeb. Eight people claimed symptoms such as nausea and breathing problems, and one of them later died.

                      June 4, 2013: French Foreign Minister Laurent Fabius asserted that there was “no doubt” that the Syrian regime used sarin in multiple cases. Fabius said that the French government confirmed the use of sarin by testing specimen taken from Syria. A UN report also said that there are “reasonable grounds” to have confidence in Syria’s use of chemical weapons four times in March and April, although the report cannot specify the chemical agents or verify who used them.

                      June 13, 2013: The White House said that the U.S. intelligence community has “high confidence” that the Assad regime attacked opposition forces by using chemical weapons multiple times over the past year. In the statement, Ben Rhodes, deputy national security adviser for strategic communications, said that physiological samples from multiple sources show exposure to chemical weapons. The evidence of use is recognized as “credible” in the statement.

                      August 14, 2013: Assad agreed to allow the UN inspection team into Syria to investigate three possible uses of chemical weapons. The team’s mandate only allows it to establish whether or not chemical weapons were used, not who used them.

                      August 21, 2013: Syrian opposition activists claimed that a large-scale chemical weapons attack occurred at the suburbs of the Ghouta region, where Syrian forces had been attempting to expel rebel force. Reports said that thousands of victims of the attack have been counted in the Damascus suburbs, whose symptoms were typically body convulsion, forming from mouths, blurry vision and suffocation. Although the number of victims has not been clarified yet, it is estimated to exceed 1,000 people, many of whom were non-combatant.

                      The United Nations Security Council also held an emergency meeting regarding the attack. The meeting produced a statement demanding further clarity of the incident.

                      August 23, 2013: UN Secretary-General Ban Ki-moon’s spokesperson expressed the intention of the UN to conduct “a thorough, impartial and prompt investigation” on the alleged chemical weapons attack in Syria on August 21.

                      The OPCW Director General, Ambassador Ahmet Üzümcü, expressed grave concerns about the latest attack in Syria, and said that the OPCW experts were already in Syria with the UN investigation team.

                      August 25, 2013: The Syrian regime announced that it will let the UN inspection team investigating past incidents of chemical weapons use visit the Damascus sites in the following days.

                      August 26, 2013: The U.S. Secretary of State John Kerry said in his press briefing that all information the U.S. has, including reports of the number of victims, their symptoms, and the firsthand accounts from humanitarian organizations, strongly indicate that chemical weapons were used in Syria. He also said that Syria attempted to cover-up the incident in the days following the attack.

                      Syrian President Bashar Assad announced that his army did not use chemical weapons in the August 21 attack in Damascus. Assad recognized the allegation of his use of chemical weapons as “politically motivated," in his meeting with Russia's Izvestia daily.

                      A convoy transporting the UN investigation team of chemical weapons was attacked by snipers in Syria. No UN personnel were injured, but they were unable to visit all of the sites affected by the attack.

                      August 28, 2013: The United States has concluded that the Assad regime conducted chemical weapons attacks against civilians, President Obama said in “PBS NewsHour.” Obama said he had not yet made a decision whether to take a military action in Syria.

                      A second UN Security Council meeting was held.

                      August 29, 2013: The British Parliament voted against supporting military action in Syria. Before the vote, a report from the Joint Intelligence Committee released a report which stated that chemical weapons were used in the August 21 attach, and that it was "highly likely" that the Assad regime was responsible.

                      August 30, 2013: The White House released the U.S. Government Assessment on the use of chemical weapons in Syria on August 21. The report says that the intelligence community has "high confidence" that the Syrian government used chemical weapons against the opposition elements in Damascus. Secretary Kerry, in an address, also said that the regime used chemical weapons "multiple times" over the past year. Kerry said discussions on military action are underway. The U.S. Government Assessment included this map of Damascus and the areas impacted by the alleged August 21 chemical weapons attack.

                      alternate text

                      August 31, 2013: President Obama made a statement saying that he would seek an authorization for the use of force from Congress for a limited military strike in Syria. Given the evidence of chemical weapons use by the Assad regime in the August 21 attack, Obama said he supported limited action in order to deter further chemical weapons use and uphold international norms.

                      September 2, 2013: France released its declassified intelligence assessment, which concluded that the Assad regime used Sarin gas in the August 21 attack, and in two earlier attacks in April. The report also said France assessed that the use of chemical weapons by the Assad regime violated the 1925 Geneva Protocol.

                      September 9, 2013: Russian Foreign Minister Sergey Lavrov announced a Russian proposition whereby Syria would agree to place its chemical weapons under international control and dismantle them and the United States would agree not to conduct a military strike on the country. Prior to the Russian announcement, Secretary of State Kerry, speaking in the United Kingdom, suggested that if the Assad regime turned over all of its chemical weapons to the international community "without delay", a military strike could be averted. Speaking to media outlets after Secretary Kerry, President Barack Obama said that the United States would consider the plan.

                      September 10, 2013: Syrian Foreign Minister Walid al-Moallem said that the Assad regime welcomed discussion on Russia's plan to give up Syria's chemical weapons and join the Chemical Weapons Convention. President Barack Obama, French President Francois Hollande, and British Prime Minister David Cameron discussed how to implement the plan through the UN Security Council, with France beginning to draft a resolution based on the Russian proposal, but with stipulations that force be authorized if Assad fails to implement the provisions of the resolution.

                      President Obama, in an address to the nation, also requested that Congress postpone a vote on the use of force while the diplomatic path proposed by the Russians is pursued in the UN Security Council. However, he also reiterated his commitment to pursue military action if a deal on securing Syria's chemical weapons is not reached.

                      September 12, 2013: The Assad regime sent a letter to the United Nations Secretary General which said that Assad signed a legislative decree providing the accession of Syria to the Chemical Weapons Convention. In the letter, Assad said Syria would observe its CWC obligations immediately, as opposed to 30 days from the date of accession, as stipulated in the treaty.

                      In Geneva, Secretary of State John Kerry met with his Russian counterpart, Foreign Minister Sergey Lavrov, to begin discussions of the Russian proposal for securing the Assad regime's chemical weapons.

                      September 14, 2013: U.S. Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov reached an agreement on a detailed plan for the accounting, inspection, control, and elimination of Syria’s chemical weapons. The plan requires Syria to provide a full declaration of its stockpile “within a week” and provide the OPCW and the UN access to all chemical weapons sites in Syria. The plan calls for the OPCW inspectors  to complete their initial inspections by November and calls for the destruction of the stockpile of chemical weapons and chemical agents by the first half of 2014. The United States and Russia secured approval of the plan by the OPCW executive council and then a UN Security Council resolution. The agreement outlined states that “in the event of non-compliance, including unauthorized transfer, or any use of chemical weapons by anyone in Syria, the UN Security Council should impose measures under Chapter VII of the UN Charter.

                      September 16, 2013: UN Secretary General Ban Ki Moon delivered a report on the UN investigation into the use of chemical weapons in Syria. The report concluded that chemical weapons were used against on August 21 on a "relatively large scale", and that the victims included civilians. The report cited evidence of the nerve agent sarin both in the environment and present in victims of the attack. It was outside of the report's mandate to assign blame for who used the chemical weapons.

                      September 20, 2013: In accordance with the terms of the agreement negotiated by the United States and Russia, Syria submitted a declaration of its stockpiles of chemical weapons to the OPCW.

                      September 27, 2013: The Executive Council of the OPCW adopted a timeline for destroying Syria's chemical weapons. Hours later, the United Nations Security Council unanimously voted to adopt a resolution that endorses the OPCW timeline for destroying Syria’s chemical weapons arsenal. The Security Council Resolution says that the body will impose measures under Chapter VII of its charter if Syria does not comply with the resolution, or uses or authorizes the transfer of any chemical agents.

                      October 1, 2013: A joint team of OPCW and UN officials arrived in Syria to begin destruction of the country's chemical weapons stockpiles and facilities.

                      October 6, 2013: Officials from the OPCW and UN team said that destruction of Syria's stockpiles of chemical weapons began. The officials confirmed that the Syrians will actually complete the destruction work, while the UN and OPCW team will monitor and verify the activities.

                      October 27, 2013: Syria submitted the details of its plans for "total and verified destruction" of its chemical weapons stockpile and production facilities to the OPCW. This declaration follows an initial declaration submitted on Sept. 20.

                      October 31, 2013: The OPCW confirmed that Syria destroyed, or rendered inoperable, all of its declared facilities for mixing and producing chemical weapons. The OPCW was able to inspect 21 of the 23 sites where these facilities were housed. The remaining two sites could not be visited due to security concerns, but inspectors said that the equipment was moved out of these sites and destroyed.

                      November 15, 2013: The OPCW Executive Council approved a plan for the elimination of Syria's stockpile of chemical weapons. The plan call for transporting the weapons outside of Syria and destruction of the chemical agents in a country that has yet to be identified. The "most critical" chemicals are to be transported out of Syria by December 31, 2013 and the remainder by February 5, 2014. The plan calls for the destruction no later than June 30, 2014, and the destruction of certain priority chemicals by March 15, 2014.

                      The Executive Council also announced that the OPCW was able to verify that 60 percent of Syrian declared, unfilled, munitions for chemical weapons delivery had been destroyed. Syria committed to destroying all of its unfilled munitions by January 31, 2014.

                      November 30, 2013: The OPCW announced that Syria's chemical weapons will be destroyed on a U.S. ship using hydrolysis. Hydrolysis is a process that breaks down chemical agents using hot water and other compounds to neutralize the agents.

                      December 12, 2013: The UN team led by Ake Sellstrom investigating incidents of chemical weapons use in Syria issued its final report to UN Secretary-General Ban Ki Moon. The report found that chemical weapons were likely used in five of the seven attacks investigated. The nerve agent sarin was likely used in four of the attacks, one of which was the large scale attack on a Damascus suburb in August.

                      December 31, 2013: Syria missed the deadline for sending all of its chemical weapons out of the country. This deadline was set by a UN Security Council Resolution approved in September.

                      2014

                      January 7, 2014: Syria delivered the first load of chemical weapons to its port city Latakia. The chemical weapons were then loaded on a Danish ship that sailed out into international waters. China and Russia are providing protection for the ship, which will eventually transfer the cargo to the US ship, the MV Cape Ray, to be neutralized using hydrolysis.

                      January 9, 2014: The German government announced its willingness to assist in the disposal of the chemical waste byproduct that will be created from the hydrolysis process.

                      January 16, 2014: Italian Transport Minister Maurizio Lupi said that Gioa Tauro, a port in southern Italy, will be used to transfer Syrian chemical weapons to the US ship, the Cape Ray, that will neutralize the chemicals using hydrolysis.

                      January 27, 2014: A second shipment of Syrian chemical weapons was loaded onto Danish and Norwegian ships at the Syrian port of Lattakia. The U.S. ship that will receive the chemical weapons and then neutralize them using hydrolysis, the Cape Ray, left port. The chemicals will be transferred to the Cape Ray at the Italian port Gioa Tauro.

                      February 6, 2014: Sigrid Kaag, head of the UN/OPCW mission for destruction of Syria's chemical weapons, addressed the UN Security Council a day after Syria missed a second deadline for handing over its critical chemicals and said that she did not believe that the Assad regime was deliberately stalling the removal process. However, she urged Syria to speed up the shipments in order to meet the destruction deadline of June 30.

                      February 10, 2014: A third shipment of Syrian chemical weapons was loaded on a Norwegian cargo ship. In total, 11 percent of Syria's chemical weapons were shipped out of Syria.

                      February 14, 2014: The OPCW announced that two companies, one in Finland (Ekokem OY AB) and one in Texas (Veolia), were awarded contracts to dispose of the effluent created during the destruction of Syria's chemical weapons.

                      February 21, 2014: The OPCW executive committed met to consider the Assad regime's new proposal for shipping out its chemical weapons. After failing to meet a Feb. 5 deadline to remove all of its chemical weapons and precursor chemicals out of the country, the regime proposed a 100 day extension. The OPCW executive committee, however, said that it can be accomplished more quickly. The 100 day extension also will not allow the Cape Ray enough time to destroy the chemical weapons by the June 30 UN Security Council deadline.

                      February 25, 2014: The Assad regime delivered a shipment of mustard gas to the Syrian port of Latakia to be loaded onto ships.

                      March 4, 2014: The Assad regime submitted a revised proposal to remove its chemical weapons from Syria by the end of April 2014. Two additional shipments of chemical weapons also reached the port of Latakia and were loaded onto ships. In total, more than 35% of the country's chemical weapons have been removed.

                      March 7, 2014: The Executive Council concluded its 75th Session and noted in its report the “increasing pace” of removal of Syria’s chemical stockpile and requested the Syria continue “systematic, predictable and substantial movements” to complete the shipments.

                      Another shipment of priority 1 chemicals was reached the port of Latakia, bringing the total amount of chemical agents removed from Syria to 29 percent of the total stockpile.

                      December 13, 2016: Allegations were made that chemical weapons were used in the Islamic State controlled areas of the Hama Governate, northwest of Palmyra. 

                      2017

                      April 4, 2017: Chemical weapons were used in an attack that killed dozens of people in Syria's northern Idlib province. Initial reports suggest the attack used sarin gas, a nerve agent. The attack is believed to have been perpetrated by the Syrian government, due to the type of aircraft in the area at the time. The OPCW announced that it is investigating the reports. Syria denied it was responsible. 

                      April 5, 2017: The UN Security Council called an emergency meeting to discuss the chemical weapons attack in Idlib. 

                      April 6, 2017: The United States used Tomahawk cruise missiles to target an air base in Syria. The Assad regime is believed to have conducted the April 4 chemical weapons attack from that base.  

                      April 11, 2017: The United States released a declassified report that confirmed victims were exposed to sarin in the April 4 attack. 

                      April 12, 2017: Russia vetoed a UN Security Council Resolution that condemned the April 4 chemical attack, called upon Syria to provide full access to investigators, and expressed determination to hold perpetrators accountable. Russia said that blame for the April 4 attack was prematurely attributed to the Assad regime. 

                      April 19, 2017: The OPCW said there was "incontrovertible" evidence that the April 4 attacks used sarin or a sarin-like substance. 

                      June 26, 2017: The White House issued a release saying it identified "possible preparations for another chemical weapons attack by the Assad regime." The statement said that Assad will "pay a heavy price" if he conducts an attack using chemical weapons. U.S. Ambassador to the UN Nikki Haley said in a separate statement that by supporting the Assad regime, Russia and Iran would also be accountable for any further use of chemical weapons. 

                      June 30, 2017: The OPCW fact-finding mechanism confirmed that sarin was used in a chemical weapons attack in Khan Sheikhoun on April 4, 2017.

                      October 24, 2017: The UN Security Council failed to adopt a resolution to extend the mandate of the OPCW-UN JIM for another year before it expires on November 17. Eleven members voted in favor of the resolution, China and Kazakhstan abstained and Boliva and Russia voted against it. The resolution did not pass because of Russia's veto.

                      October 26, 2017: The seventh report of the OPCW-UN joint investigative mechanism found the Assad regime guilty of using sarin nerve agent in the April 4 attack in Khan Sheikhoun and the Islamic State responsible for the use of sulfur mustard at Umm Hawsh in September 2016.

                      November 6, 2017: The OPCW Fact-Finding Mission reported that sarin was more than likely used as a chemical weapon on March 30, 2017 in the south of Ltamenah.

                      November 8, 2017: U.S. Secretary of State Rex Tillerson, U.K. Foreign Secretary Boris Johnson, French Foreign Minister Jean-Yves Le Drian and German Foreign Minister Sigmar Gabriel released a joint statement condemning the use of chemical weapons in Syria as described in the seventh JIM report and calling on the UN Security Council to act to continue the investigations. 

                      November 16, 2017: The mandate of the OPCW-UN JIM, responsible for determining the culpable actor for chemical weapons attacks in Syria, expired after both resolutions introduced at the UN Security Council to extend it failed. The resolution sponsored by the United States received 11 votes in favor, 2 against and 2 abstentions and failed because Russia vetoed it. The Russian resolution received 4 votes in favor, 7 against and 4 abstentions.

                      November 17, 2017: A UN Security Council resolution introduced by Japan to extend the JIM's mandate for 30 days received 12 votes in favor but failed because of a Russian veto. 

                      2018

                      January 23, 2018: France launched the International Partnership Against Impunity for the Use of Chemical Weapons, a new initiative that seeks to increase information sharing about reported chemical weapons attacks and publically lists individuals and entities sanctioned for their involvement in chemical weapons use. Russia then called a last minute UN Security Council meeting, introducing a new proposal to extend the Joint Investigative Mechanism (JIM). The United States rebuked the proposal on the grounds that it was merely intended as a distraction from the launch of the new partnership.

                      February 1, 2018: The third chemical weapon attack in 2018 in Douma, Damascus is reported. The two earlier attacks were reported on January 13 and January 22. Reports assess that chlorine gas was used in all attacks. At a UN Security Council briefing on February 5, UN High Representative for Disarmament Affairs Izumi Nakamitsu stated that reports from the OPCW Fact-Finding Mission on these alleged attacks are pending.

                      April 7, 2018: Reports surfaced of a major chemical weapons attack in Douma, a suburb outside of Damascus, Syria, killing at least several dozen civilians. This followed smaller chlorine gas attacks that were reported in Douma on March 7 and 11. Human Rights Watch has documented 85 chemical weapons attacks since 2013 in Syria. The OPCW announced that its Fact Finding Mission is investigating the incident to determine which chemical weapons may have been used.

                      April 10, 2018: The UN Security Council voted on three resolutions to address chemical weapons use in Syria. Russia vetoed a U.S.-sponsored resolution which would have created a UN Independent Mechanism of Investigation with a one-year mandate to investigate the responsible actors for chemical weapons use in Syria. A Russian resolution which would have created a similar body but would have allowed the UN Security Council, not the investigative body, to ultimately determine accountability failed to receive enough votes to pass. A second Russian resolution, which urged the OPCW Fact Finding Mission to investigate the incident and offered Russian military protection for investigators, also failed to receive enough votes to pass. The OPCW had already announced earlier that day that it was planning to deploy a Fact-Finding Mission to Douma. 

                      April 13, 2018: The UN Security Council met for the fourth time that week to discuss chemical weapons use in Syria. Russia and Bolivia continued to urge the United States against taking unilateral military action as the United States, France and the United Kingdom seemed to make the case for a strike. "Should the United States and our allies decide to act in Syria, it will be in defense of a principle on which we all agree, U.S. UN Ambassador Nikki Haley said.

                      France, the United Kingdom and the United States launched precision strikes on three Syrian chemical weapons facilities. In a televised address to the nation, President Trump explained that the purpose of the strike was to "establish a strong deterrent against the production, spread and use of chemical weapons." He continued "To Iran and Russia, I ask: What kind of a nation wants to be associated with the mass murder of innocent men, women and children?" Syrian state television reported that its air defense system had shot down 13 of the missiles, although the United States later denied that any missiles had been engaged. Russian Ambassador Anatoly Antonov said in a statement shortly after the announcement of the strike: "We warned that such actions will not be left without consequences."

                      April 14, 2018: The OPCW Fact-Finding Mission was in Syria investigating the April 7 chemical weapons attack to verify that the attack occurred and to identify which chemical agent was used. 

                      France released its national assessment of the April 7 chemical weapons attack, concluding that "(i) beyond possible doubt, a chemical attack was carried out against civilians at Douma on 7 April 2018; and (ii) that there is no plausible scenario other than that of an attack by Syrian armed forces as part of a wider offensive in the Eastern Ghouta enclave."

                      The UN Security Council met to discuss the situation in Syria. The United Kingdom stated that the legal basis for its joint strike was humanitarian intervention. Russia and Bolivia condemned the strike, which they asserted was a violation of the UN Charter. Russia also introduced a draft resolution which condemned "aggression against the Syrian Arab Republic by the US and its allies," but it only received three votes and failed to pass. France, the United Kingdom and the United States announced their intention to introduce a draft resolution on political and humanitarian tracks to resolve the conflict.

                      April 21, 2018: The OPCW Fact-Finding mission team visited one of the sites in Douma to collect samples for analysis in connection with the April 7 attack. 

                      May 16, 2018: The OPCW Fact-Finding mission reported that "chlorine, released from cylinders through mechanical impact, was likely used as a chemical weapon on 4 February 2018 in the Al Talil neighborhood of Saraqib."

                      June 13, 2018: The OPCW Fact-Finding mission reported that sarin was "very likely used as a chemcial weapon" in Ltamenah, Syria on March 24, 2017 and that chlorine was "very likely used as a chemical weapon" at and around Ltamenah Hospital on March 25, 2017.

                      June 27, 2018: A special session of the OPCW conference of states-parties voted to grant the OPCW the mandate to investigate and attribute responsibility for chemical weapons attacks in Syria confirmed by the Fact-Finding Mission.

                      September 12, 2018: The Independent International Commission of Inquiry on the Syrian Arab Republic, established in 2011 by the UN Human Rights Council reported that the Syrian government used chlorine as a weapon four times from January to July 2018.

                      Updated: October 2018

                      On April 8, 2010, Russia and the United States signed the New Strategic Arms Reduction Treaty (New START). The treaty requires both sides to limit the number of deployed strategic nuclear warheads to no more than 1,550 and fielded delivery platforms to 700. The treaty also permits the United States and Russia to conduct 18 annual on-site inspections of facilities operated by the other country. Biannual data exchanges indicate the current state of their strategic forces.

                      As of September 2018, Russia had 517 deployed strategic delivery systems and 1,420 deployed strategic nuclear warheads. Russia is in the process of both retiring many of its older strategic systems and replacing them with new systems.

                      Submarine-Launched Ballistic Missiles (SLBMs) and Submarines

                      Submarines

                      As of early 2017, the Navy had 12 functional strategic submarines of three different types, 11 of which are functional and one is being overhauled. They are deployed with the Northern Fleet and the Pacific Fleet. Bases of the Northern Fleet host six 667BDRM (Delta IV) submarines. The Delta IVs are undergoing overhaul in which they are being equipped with new missiles. The Pacific Fleet base hosts three 667BDR (Delta III) submarines but these are being withdrawn from service. Project 955 (also known as Borey or Yuri Dolgorukiy) is the newest class of submarines. Construction began in 1996 and the first joined the Northern Fleet in 2013, though subsequent submarines of this class will join the Pacific Fleet. As of January 2016, three Project 955 submarines have been accepted into service. When the missiles on Project 941 (Typhoon) class submarines reached the end of their service lives, these submarines were withdrawn from service. The one exception is the lead ship of the class, TK-208 Dmitry Donskoy, which was refitted for the new missile system, R-30 Bulava, which is designed for deployment on the Borev-class nuclear submarines The Borey class submarines are expected to constitute the core of the Russian strategic submarine fleet, replacing the aging Project 941 and Project 667 boats. Russia is planning to build eight Borey and Borey-A class subs by 2020.

                      Submarine-Launched Ballistic Missiles

                      RIA News reported, in June 2012, that the Bulava sea-based ballistic missile had entered service. The Bulava (SS-NX-30) SLBM, developed by the Moscow Institute of Thermal Technology, carries up to 6 MIRV warheads and has a range of over 8,000 kilometers (5,000 miles). Borey class strategic submarines will carry up to 16 Bulava ballistic missiles, each with multiple warheads.
