IAEA Report Confirms Iran’s Compliance with the JCPOA

The International Atomic Energy Agency (IAEA) released its quarterly report on Iran’s nuclear program June 6, and, unsurprisingly, the report found that Iran is complying with its commitments under the multilateral deal known as the Joint Comprehensive Plan of Action (JCPOA) . The report, finalized May 24, was the first since U.S. President Donald Trump violated the nuclear deal May 8 by reimposing sanctions on Iran, and withdrew the United States from the accord. The report bears out what Iranian officials stated after Trump’s announcement – that Iran would remain within the JCPOA, for now...

EU Moves to Block U.S. Iran Sanctions

Close U.S. allies push back after Trump rejects personal appeals not to quit the Iran nuclear deal.

June 2018
By Kelsey Davenport

U.S. President Donald Trump’s decision to withdraw from the nuclear deal with Iran and reimpose sanctions on that country is spurring Europe to block U.S. measures and shore up support to sustain the agreement.

By pulling out of the 2015 multilateral nuclear agreement, Trump delivered on a campaign promise to “tear up” the deal with Iran, which he has frequently disparaged as the “worst deal ever negotiated.” In doing so, he rebuffed personal last-minute appeals by French President Emmanuel Macron and German Chancellor Angela Merkel during their visits to the White House in late April.

(Photo: Saul Loeb/AFP/Getty Images)Trump said on May 8 that if he “allowed this deal to stand, there would soon be a nuclear arms race in the Middle East.” Trump said the process he initiated in January to work with European partners to “fix” the accord is not possible under the “decaying and rotten structure of the current agreement,” despite U.S. Secretary of State Mike Pompeo telling allies days before the announcement that he felt an agreement could be reached to address U.S. concerns. (See ACT, March 2018.)

Following up the president’s action, Pompeo in a May 21 speech outlined a broad list of demands on Iran and said the United States will impose the “strongest sanctions in history” to force Iran to end certain nuclear activities and missile programs, aid to the Syrian regime and support for militant groups in the region. The set of demands, stopping just short of an explicit call for regime change, sets the stage for further U.S. tensions with European allies and the Islamic Republic.

Even before Pompeo’s policy speech, Trump’s announcement earned sharp rebukes from Washington’s partners in the agreement, as well as the European Union, and commitments by those nations to continue implementing the accord. The extent to which that is possible is unclear, given that major foreign companies face being cut off from the U.S. banking system and other punishment if they do not adhere to U.S. sanctions on Iran.

European Council President Donald Tusk was particularly direct in his criticism, tweeting on May 16 that “[l]ooking at the latest decisions of President Trump, someone could even think: With friends like that, who needs enemies?”

Iranian President Hassan Rouhani reiterated Iran’s commitment to continue abiding by the agreement, so long as Iran’s national interests are met, and said he was pleased that “the troublesome member has been eliminated” from the deal.

But Iranian Supreme Leader Ayatollah Ali Khamenei said that he wants to see “definite reassurance” and “practical guarantees” that Iran will receive the sanctions relief envisioned under the deal.

Federica Mogherini, the EU foreign policy chief, said that guarantees are not possible but that the EU is determined to “act in accordance with its security interests and to protect its economic investments.” She met on May 15 with Iranian Foreign Minister Javad Zarif and the foreign ministers of France, Germany, and the UK to discuss moving forward without the United States.

How Might Iran Expand Its Nuclear Capacity?

In deciding to violate the 2015 Iran nuclear deal, President Donald Trump has put at risk the extensive measures the Joint Comprehensive Plan of Action (JCPOA) imposed to block Iran from building nuclear weapons.

How long would it take if Tehran’s leaders now decide to race for the bomb? One accomplishment of the nuclear deal is that it imposed hurdles intended to ensure that Iran could not do it in less than a year. Further, for now, Iran would not be able to attempt it without being detected, thanks to the robust international inspection and monitoring required by the nuclear accord.

That timeline and the inspection tripwires could, however, become less reliable depending on Iran’s actions following the unilateral U.S. decision to reimpose sanctions.

Iranian leaders have raised the possibility of abandoning some or all of the tough nuclear restrictions they accepted in 2015 in return for the lifting of nuclear-related international sanctions. Iran could take steps, such as scaling up its nuclear program or reducing cooperation with International Atomic Energy Agency (IAEA) inspectors, that would violate its JCPOA commitments.

“If necessary, we can begin our industrial [uranium] enrichment without any limitations,” Iranian President Hassan Rouhani said on May 8. “We will wait for some weeks and will talk with our friends and allies and other signatories of the nuclear deal, who signed it and who will remain loyal to it. Everything depends on our national interests.”

Iran currently has 5,060 installed IR-1 centrifuge machines and a relatively small inventory of low-enriched uranium of less than 300 kilograms. Iran could quickly begin enriching the material to 20 percent uranium-235, although it would still take at least 12 months to amass enough uranium enriched further to bomb grade for one nuclear device.

Ali Akbar Salehi, head of the Atomic Energy Organization of Iran, said on April 21 that if the decision were made, it would take just four days to resume enrichment to 20 percent U-235. Enrichment to that level is short of the enrichment level of 90 percent necessary for weapons use, but it would reduce the time needed to produce bomb-grade material. The nuclear deal limits enrichment to levels below 3.67 percent U-235, suitable for fueling nuclear power reactors.

Iran also could reorient the Fordow underground enrichment complex, which became a physics and technology research center under the deal, and use some 1,000 IR-1 machines there. Iran’s centrifuge-based nuclear infrastructure could be further augmented with the redeployment of some 1,000 advanced IR-2M centrifuges, which were put into monitored storage under the JCPOA. Because these are two to three times more efficient than the IR-1s, their use, along with the IR-1 machines at Iran’s disposal, would reduce the time necessary to produce enough weapons-grade uranium for one bomb to two to three months.

With the existing IAEA monitoring system in place, all of these steps would be promptly detected. But within months of a decision to exceed the JCPOA limits, Iran could have a vastly shorter “breakout” timeline.

Breakout calculations must take into account the fact that, before 2004, Iran engaged in an organized program of experiments useful for the development and design of nuclear weapons. U.S. intelligence agencies and the IAEA report that program is no longer underway, although it is prudent to assume that Iran has the know-how to assemble a nuclear device.

At present, Iranian engineers and scientists, building on past know-how, would likely need at least a year to assemble a workable nuclear device and mate it to a reliable ballistic missile delivery system.—DARYL G. KIMBALL

Subsequently, at a May 17 meeting of the European Commission, the body agreed to take steps in response to Trump’s reimposition of sanctions, including revising a blocking statute used by the EU in the 1990s to protect entities from U.S. sanctions on Cuba. The blocking regulation “forbids EU companies from complying with the extraterritorial effects of U.S. sanctions, allows companies to recover damages arising from such sanctions from the person causing them, and nullifies the effect in the EU of any foreign court judgements based on them,” according to a May 17 press release.

The EU is aiming to have the measure in force by Aug. 6, the day some U.S. sanctions go into effect. Although the United States has reimposed sanctions, the U.S. Department of the Treasury announced on May 8 that entities would be given 90 or 180 days to wind down activities in Iran before sanctions would be enforced.

For large, multinational companies with a significant presence in the United States, the blocking regulation is unlikely to provide enough assurance for them to remain in the Iranian market. Several announced that they are winding down business in Iran and exiting contracts.

The regulation sends a strong political signal, however, and may provide cover for smaller businesses with less of a presence in the United States to continue doing business in Iran. The EU also launched a process whereby the European Investment Bank will be able to support investment activities in Iran.

EU measures to blunt the impact of sanctions call into question Trump’s plan to pressure Iran back to negotiations. Brian Hook, State Department director for policy planning, in a May 18 press conference described the goal of sanctions reimposition as creating “necessary pressure to bear on Iran to change its behavior and to pursue a new framework” that addresses Iran’s ballistic missile development and its support for terrorism, as well as its nuclear program.

In the lead up to the 2015 nuclear agreement, known formally as the Joint Comprehensive Plan of Action (JCPOA), EU sanctions and EU compliance with U.S. sanctions were a critical part of the pressure campaign that pushed Iran to negotiate. With the EU and China, Russia, and other states retaining business ties with Iran, it is unlikely that the United States will be able to press Iran into new negotiations.

Trump Draws International Criticism for Quitting Iran Deal

U.S. President Donald Trump’s decision to unilaterally withdraw from the Iran nuclear deal drew unusually strong criticism from U.S. allies and from partners in the negotiations. Some of those reactions:

“France, Germany, and the UK regret the U.S. decision…. The nuclear nonproliferation regime is at stake.”—French President Emmanuel Macron

“Imagine all the mutually contaminating civil wars and internecine conflicts that rage across the Middle East today. Then turn the dial, and add the possibility of a regional nuclear arms race triggered by Iran dashing for a bomb. That is the scenario which the agreement has helped to prevent.”—UK Foreign Minister Boris Johnson

Newspapers in Tehran on May 9 headline the U.S. withdrawal from the nuclear deal. (Photo:  Atta Kenare/AFP/Getty Images)“The [deal], agreed to with Iran in 2015 and endorsed by the UN Security Council, is not perfect. It has, however, helped to curb a real threat to international peace and security. Canada regrets that the United States has decided to withdraw…particularly given that, according to the [International Atomic Energy Agency], Iran continues to implement its…commitments.”
—Canadian Foreign Minister Chrystia Freeland

“I believe that it’s not right to unilaterally cancel an accord that was negotiated, that was confirmed in the UN Security Council unanimously.”—German Chancellor Angela Merkel

“The action plan does not belong to the United States alone but is a domain of the entire international community, which has repeatedly reaffirmed its interest in the preservation and long-term sustainable implementation of the [Iran deal] for the sake of strengthening international and regional peace and security as well as the nuclear nonproliferation regime.... Russia is open to further cooperation with the other…participants and will continue to actively develop bilateral collaboration and political dialogue with the Islamic Republic of Iran.”
—Russian Foreign Ministry statement

“The agreement is not perfect, and we must continue to address concerns about Iran’s ballistic missile program and its role in the region…. The U.S. decision is a step backwards. The Netherlands will work with our partners to find a solution that safeguards our own security and that of the entire European Union.”—Dutch Foreign Minister Stef Blok

“Australia is disappointed.”—Australian Foreign Minister Julie Bishop

Iran has left open the option to resume troublesome nuclear activities in response to the U.S. violation and withdrawal from the deal. In a move likely meant to signal that Iran will leave the JCPOA if the remaining parties to the agreement cannot deliver on sanctions relief, Rouhani ordered the Atomic Energy Organization of Iran (AEOI) to be “fully prepared for subsequent measures if needed, so in the case of need, we will start up our industrial enrichment without limitations.”

Other Iranian officials, including AEOI head Ali Akhbar Salehi, have specifically said Iran would resume enriching uranium to 20 percent uranium-235, a level that would put Tehran closer to the 90 percent U-235 required for use in nuclear weapons.

Under the JCPOA, Iran is limited to enriching uranium to 3.67 percent U-235, a level suitable for nuclear power reactors, using no more than 5,060 installed centrifuges. The accord also limits Iran to a stockpile to 300 kilograms of uranium enriched to that level, a measure to hinder any nuclear-bomb effort.

Yukiya Amano, director-general of the International Atomic Energy Agency, confirmed on May 8 that Iran is meeting its commitments under the accord, and the agency’s May 24 quarterly report on Iran’s nuclear activities further confirmed that Tehran had not taken any steps to violate the deal after Trump withdrew.

National Members Call: The Future of the Iran Deal and the U.S-North Korea Summit



Join Arms Control Association Executive Director Daryl Kimball and Director for Nonproliferation Policy Kelsey Davenport for a members-only briefing on the future of the Iran Deal and the upcoming U.S.-North Korea Summit.


The Trump administration is moving to reimpose sanctions on Iran and any U.S. or foreign businesses that continue to do business with the country in defiant violation of the 2015 nuclear deal. 

The Trump administration’s vision of a “better deal” with Iran, as Secretary of State Mike Pompeo described in speaking at the Heritage Foundation today, is like a mirage in the desert—it may look good, but it is not real and there is no path to get there.

And by trying to, the United States only risks the deal at hand.

Trump’s actions could open the door for Iran to expand its nuclear capabilities, leading to a new proliferation crisis and an arms race in the Middle East. Worse still, his decision to violate the Iran deal could undermine the negotiations and change the outcomes at next month's historic summit between the United States and North Korea.

Join Arms Control Association Executive Director Daryl Kimball and Director for Nonproliferation Policy Kelsey Davenport for a members-only briefing on these developments.

This is your opportunity to engage directly with our national staff and ask what we can expect over the next few months and what these decisions mean for the United States, Iran, North Korea, and the rest of the world.

Pompeo's Vision of “Better” Iran Deal is an Illusion

In his May 21 speech at the Heritage Foundation , the new U.S. Secretary of State, Mike Pompeo, defended Trump’s decision earlier this month to violate the 2015 multilateral nuclear deal with Iran, withdraw from the agreement, and pursue a “better deal.” But the Trump administration’s vision of a “better deal” with Iran is like a mirage in the desert—it may look good, but it is not real and there is no path to get there. And by trying to, the United States only risks the deal at hand. What Pompeo failed to articulate is how that “better deal” is possible, given that key U.S. allies and...

The P4+1 and Iran Nuclear Deal Alert, May 16, 2018

The Nuclear Deal Minus the United States? President Donald Trump’s irresponsible decision to violate the Joint Comprehensive Plan of Action (JCPOA) agreement with Iran and withdraw from the accord was unanimously denounced by the other parties to the agreement. Washington’s P5+1 partners – the EU, China, France, Germany, Russia, and the United Kingdom, also announced their intention to sustain the agreement and fully implement it without the United States. Iranian President Hassan Rouhani also pledged to continue abiding by the terms of the deal if Iran’s interests are met. But he ordered the...

White House Should State Opposition to Saudi Nuclear Weapons Threat



It is bad enough that the Trump administration has violated the Iran nuclear deal and threatened the NPT regime by opening the door for expanded Iranian nuclear capacity. The president and his advisors must not now compound that error by swallowing their tongues when another NPT member state in the region threatens to pursue the bomb.


For Immediate Release: May 15, 2018

Media Contacts: Daryl G. Kimball, executive director, (202) 463-8270 ext. 107; Thomas Countryman, board of directors chair, (202) 463-8270 ext 110

We are deeply disappointed by the counterproductive response from the Trump administration to the statements from senior Saudi officials threatening to pursue nuclear weapons in violation of their nonproliferation commitments.

We call on the White House to immediately reiterate the longstanding, bipartisan policy of the United States that it will actively work against the spread of nuclear weapons to any country, friend or foe.

President Donald Trump’s reckless decision to violate the Joint Comprehensive Plan of Action, which has blocked Iran’s pathways to nuclear weapons and put in place a robust monitoring system to detect and deter cheating, has not only opened the door to an expansion of Iran’s capability to produce bomb-grade nuclear material, but it has increased the risk of a wider nuclear arms race in the Middle East, which is already home to one nuclear-armed state.

Saudi Arabia's foreign minister Adel Al-Jubeir told CNN Wednesday, May 9, that his country, which, like Iran, is a party to the 1968 nuclear Nonproliferation Treaty (NPT), stands ready to build nuclear weapons if Iran restarts its nuclear program.

Al-Jubeir also praised Trump's decision to abandon the Iran nuclear deal and seek to reimpose sanctions on firms and business engaging in legitimate commerce with Iran.

Asked what his country will do if Iran restarts its nuclear program, he told CNN's Wolf Blitzer that "we will do whatever it takes to protect our people. We have made it very clear that if Iran acquires a nuclear capability, we will do everything we can to do the same."

Asked to clarify whether that means the kingdom will work to acquire its own nuclear capability, al-Jubeir replied, "That's what we mean."

This follows similar comments by Saudi Crown Prince Mohammed bin Salman in a March 15 interview with CBS News that Saudi Arabia will quickly follow suit if Iran acquires nuclear weapons.

When asked May 9 whether Saudi Arabia would “have the administration’s support in the event that that occurred,” White House Press Secretary Sarah Huckabee Sanders said:

“Right now, I don’t know that we have a specific policy announcement on that front, but I can tell you that we are very committed to making sure that Iran does not have nuclear weapons,” she stated.

The administration’s nonresponse to Prince Salman’s threat in March and Sanders’ weak response May 9 amounts to an irresponsible invitation for mischief.

They imply that Trump administration would look the other way if Saudi Arabia breaks its NPT commitments to pursue nuclear weapons.

It is bad enough that the Trump administration, by violating the 2015 Joint Comprehensive Plan of Action, has threatened the NPT regime by opening the door for Iran to expand its nuclear capacity.

President Trump and his advisors must not compound that error by swallowing their tongues when another NPT member state in the region threatens to pursue the bomb.

We call on the White House to immediately clarify that it is the longstanding policy of the United States, as an original party to the NPT:

 “…not to in any way to assist, encourage, or induce any non-nuclear-weapon State to manufacture or otherwise acquire nuclear weapons …” and “… to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament ….”

We also call on the U.S. Congress to reject any proposed agreement with Saudi Arabia that permits U.S. nuclear cooperation if Saudi Arabia seeks to or acquires sensitive uranium enrichment or plutonium separation technology which can be used to produce nuclear weapons.

Trump just opened the door for Iran to expand its nuclear capabilities

This op-ed originally appeared in The Hill . Fulfilling a misguided campaign pledge, President Trump has chosen to violate the 2015 nuclear deal between the United States and its partners — the EU, U.K. France, Germany, Russia, and China — with Iran and reimpose U.S. sanctions that were waived according to the terms of the 2015 accord in exchange for severe limits and very robust international monitoring on Iran’s nuclear activities. Now, the valuable nonproliferation barriers established by the agreement, known as the Joint Comprehensive Plan of Action (JCPOA), are at risk. Contrary to Trump...

Arms Control and Proliferation Profile: Iran

May 2018

Updated: May 2018

Iran is not a nuclear-weapons state and, though it has pursued a program to develop nuclear warheads in the past, has adhered to the terms of the Joint Comprehensive Plan of Action (JCPOA) since adoption in October 2015, as verified by all quarterly IAEA reports. Under the JCPOA, for well over a decade, it will take Iran 12 months to produce enough weapons-grade uranium for one bomb. The deal also bars Iran from selling conventional arms for five years from the start of implementation, though branches of the Islamic Revolutionary Guard Corps continue to allegedly smuggle arms to Iranian proxies in Syria, Lebanon, and elsewhere. Iran’s active ballistic missile program is one of the largest deployed missile forces in the Middle East, with over 1,000 short- and intermediate-range ballistic missiles as well as a space-launch vehicle that could potentially be converted into an ICBM.

Nuclear Weapons Programs, Policies, and Practices

The Nuclear Arsenal, an Overview

Iran does not possess nuclear weapons but it conducted activities in the past relevant to developing a nuclear warhead, including uranium enrichment and studies on ballistic missile mating and re-entry. In July 2015, after a decade of intermittent negotiations, Iran along with the “P5+1” (China, France, Germany, Russia, the United Kingdom, and the United States) concluded the Joint Comprehensive Plan of Action (JCPOA), frequently referred to as the Iran nuclear deal. The Iran nuclear deal restricts Iran’s nuclear activities and puts in place monitoring and verification measures in addition to Iran’s safeguards. On May 8, 2018, President Trump announced that the United States would withdraw from the JCPOA and reinstate U.S. nuclear sanctions on the Iranian regime. For more on the deal see the Joint Comprehensive Plan of Action at a Glance.   

Delivery Systems

Ballistic Missiles

  • Iran’s missile program is largely based on North Korean and Russian designs and has benefitted from Chinese technical assistance.
  • With approximately 1,000 short- and medium-range ballistic missiles, the program is one of the largest deployed ballistic missile forces in the Middle East.
  • Iran’s current focus is on enhancing the accuracy of medium-range systems - not increasing range.
  • Iran's Supreme Leader Ayatollah Ali Khamenei stated that Iran would refrain from manufacturing ballistic missiles exceeding a range of 2,000km, General Mohammad Ali Jafari, the head of the Revolutionary Guard, told reporters on Oct. 31, 2017. The limitation is not legally binding.
  • UN Security Council Resolution 2231, which endorsed the JCPOA in 2015, annulled a 2010 resolution that prohibited Iranian tests of nuclear-capable ballistic missiles and “calls upon” Iran not to test any ballistic missiles that are “designed to be nuclear capable.” Resolution 2231 also kept in place sanctions preventing Iran from transferring materials and technologies relevant to developing ballistic missiles.
  • Iran has continued ballistic missile testing in the wake of the nuclear deal. In response, the United States has designated additional entities for contributing to Iran’s ballistic missile program.
  • Iran’s short-range and medium-range missiles include:
    • Fateh-110: The Fateh-110 is an operational short-range missile with an estimated range of 200-300km.
    • Shahab-1: The Shahab-1 is an operational, short-range missile with an estimated range of 300km.
    • Qiam-1: The Qiam is an operational short-range missile with an estimated range of 500-1000km.
    • Shahab-2: The Shahab-2 is an operational short-range missile with an estimated range of 500km.
    • Fateh-313: The Fateh-313 is an operational short-range missile with an estimated range of 500km.
    • Zolfaghar: The Zolfaghar is an operational missile with an estimated range of 700km.
    • Shahab-3: The Shahab-3 is an operational missile with an estimated range of 800-1,000km. A liquid-fueled missile based on the North Korean No-Dong, it is Iran’s most sophisticated missile.
    • Emad-1: The Emad-1 is a single-stage medium-range ballistic missile under development with a range of up to 2,000 km. First tested in 2015, Iran claims the Emad-1 is a high-precision missile.
    • Ghadr-1: The Ghadr-1 is a medium-range missile under development with an estimated range of up to 2,000 km. The missile is a modified version of the Shahab-3.
    • Sejjil-2: The Sejiil is an intermediate-range missile under development with an estimated range of 1,500-2,500km. First tested in 2007, the Sejill is a two-stage solid fuel-propelled missile. The Sejjil-2 has not been tested since 2011 and reports indicate Iran has a hard time producing the solid-fueled motors because of sanctions. This technology could help improve the mobility of Iran’s missile force. 

Space-Launched Vehicles (SLV)

  • Safir: The Safir is a two-stage, liquid-fueled space launch vehicle (SLV) that Iran has used to successfully launch four satellites into space between February 2009 and February 2012. Two Safir launches subsequently failed, once in 2013 and again in 2014. In February 2015, Iran successfully launched a satellite for the fifth time. A 2009 report by the National Air and Space Intelligence Center (NASIC) assessed that the Safir “can serve as a test bed for long-range ballistic missile technologies” and could serve as an ICBM if converted to a ballistic missile.
  • Simorgh: The Simorgh is a two-stage SLV that Iran has displayed, but not launched. It is larger than the Safir. The first Simorgh launch was announced for 2010.

Cruise Missiles

  • Iran possesses the following cruise missiles:
    • Kh-55: An air-launched nuclear-capable cruise missile with a range of up to 3,000 km which was illegally procured from the Ukraine in 2001.
    • Khalid Farzh: Iran’s most advanced missile with a range of about 300 km capable of carrying a 1,000 kg warhead.
    • Nasr-1: A domestically produced missile which is claimed to be capable of destroying warships and military targets up to 3,000 tons.

Fissile Material

  • During the latter half of 2002, the IAEA began investigating two secret Iranian nuclear facilities: a heavy-water production plant near Arak and a gas centrifuge uranium-enrichment facility near Natanz.
  • In September of 2009, the discovery of Fordow, a secret nuclear facility under construction near Qom, deepened international suspicions about Iran’s uranium enrichment activities.
  • In 2010, Iran scaled up some of its uranium enrichment from less than 5 percent to 20 percent, the level required for Iran’s research reactor.
  • Under the Iran deal, Iran’s enriched uranium is capped at 3.67 percent.
  • Much of the uranium-enrichment program is based on equipment and designs acquired through former Pakistani nuclear official A.Q. Khan’s secret supply network.
  • Iran relies on its IR-1 centrifuge, a variant of Pakistan’s P-1 centrifuge, known to be crash-prone and unreliable. 
  • Under the 2015 nuclear deal, Iran is permitted a strictly limited amount of R&D on advanced centrifuges.  

The Road to the JCPOA

  • In 2006, the Security Council adopted a number of resolutions calling on Iran to suspend uranium enrichment-related activities and cooperate fully with the IAEA.
  • When Iran refused to comply, the UNSC introduced four rounds of sanctions targeting Iranian entities and individuals believed to be involved in Iran’s proliferation-related activities.
  • In 2009, Russia, France, and the United States negotiated a fuel swap deal with Iran to transfer low-enriched uranium (LEU) out of the country in exchange for fuel for a reactor that produces medical isotopes. The deal fell through when Iran tried to change the terms.
  • In 2012, the P5+1 continued diplomatic efforts and met with Iran on four separate occasions. These talks were suspended for the 2013 Iranian elections though they did lay the groundwork for what would become the JCPOA.
  • After President Rouhani was elected in June of 2013, Iranian Foreign Minister Javad Zarif and U.S. Secretary of State John Kerry met for a bilateral exchange. A day later, President Obama called President Rouhani, marking the highest level contact between the U.S. and Iran since 1979.
  • Negotiations to curb the Iranian nuclear program took place in October and November 2013 and an interim agreement was reached November 24. Implementation of the interim agreement began on January 20, 2014. The interim agreement was extended twice before the comprehensive agreement was finalized. Along the way all parties implemented changes and did not violate the interim agreement. Learn more about the interim agreement here.
  • The final agreement is known as the Joint Comprehensive Plan of Action (JCPOA) and was finalized on July 14, 2015. The implementation schedules and enforcement options are governed by UN Security Council Resolution 2231, which was adopted on July 20, 2015. Learn more about the JCPOA.   
  • According to U.S. government estimates, under the JCPOA, for well over a decade, it will take Iran 12 months to produce enough weapons-grade uranium for one bomb.
  • The IAEA reports quarterly on Iran's adherence to the JCPOA. Two reports in 2016 noted slight excesses in heavy-water. Iran rectified this by selling or shipping abroad part of its stocks. The P5+1 and Iran subsequently clarified the heavy-water limit.
  • On May 8, 2018, President Trump announced that the United States would withdraw from the JCPOA and reinstate U.S. nuclear sanctions on the Iranian regime. 

Proliferation Record

  • In 2000, Iran exported rockets and several ballistic missile components to Libya.
  • Iran has been accused of violating a Security Council resolution barring arms transfers to Hezbollah.
  • Since 2007, the Security Council has barred Iran from selling conventional arms and also prohibits any country from importing arms from Iran without prior UN Security Council approval. Under UN Security Council Resolution 2231 the embargo on Iran’s export of conventional arms will remain in place for five years from JCPOA Adoption Day (October 2015). This embargo may be lifted earlier if the IAEA reaches a “Broader Conclusion” that Iran’s nuclear program remains peaceful.
  • According to a 2012 report by a designated panel of experts, Iran has been a major supplier of weapons to the Syrian government. The report describes three illegal transfers, two to Syria and one to the Taliban in Afghanistan.
  • Unit 190, a branch of the Islamic Revolutionary Guard Corps, is responsible for smuggling arms to Iranian proxies in Syria, Lebanon, and elsewhere.

Biological Weapons

  • Iran has ratified the Biological Weapons Convention but the United States maintains Iran’s biotechnology infrastructure gives it the ability to produce small quantities of biological weapons agents for offensive purposes.
  • According to a 2004 CIA report, Iran has previously conducted offensive biological weapons agent research and development and continues to seek dual-use biotechnology.
  • U.S. officials have accused Iran of “probably” pursuing an offensive biological weapons capability in violation of the Biological Weapons Convention in 2011. Iran denies the allegation.

Chemical Weapons

Conference on Disarmament

  • At the 2012 Conference on Disarmament, Iran said it was not opposed to negotiations of a Fissile Material Cutoff Treaty (FMCT) but that it should not infringe on any state’s right to use fissile material for peaceful purposes or naval propulsion.

The Joint Comprehensive Plan of Action (JCPOA) at a Glance

May 2018

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

May 2018

The Joint Comprehensive Plan of Action (JCPOA) is a detailed, 159-page agreement with five annexes reached by Iran and the P5+1 (China France, Germany, Russia, the United Kingdom, and the United States) on July 14, 2015. The nuclear deal was endorsed by UN Security Council Resolution 2231, adopted on July 20, 2015. Iran’s compliance with the nuclear-related provisions of the JCPOA will be verified by the International Atomic Energy Agency (IAEA) according to certain requirements set forth in the agreement. On May 8, 2018, President Trump announced that the United States would withdraw from the JCPOA and reinstate U.S. nuclear sanctions on the Iranian regime. 

The following is a summary of the timeline and key components of the multi-year agreement.

Timeline for Implementation

July 14, 2015, Finalization Day: conclusion of the agreement. Finalization day triggers Iran and the United States to begin domestic review processes of the JCPOA. Iran also begins providing the IAEA with information necessary for the agency to complete its investigation into past activities related to nuclear weapons development. 

October 18, 2015, Adoption Day: 90 days after the passage of the UN Security Council Resolution endorsing the deal (July 20, 2015). Adoption day triggers Iran and the P5+1 to take steps (outlined below) to meet the commitments to fully implement the JCPOA. 

 January 16, 2016, Implementation Day: the IAEA certifies that Iran has taken the key steps to restrict its nuclear program and has put in place increased monitoring. The IAEA's report on implementation day triggers U.S., EU, and UN sanctions relief. 

  • October 2023, Transition Day: Eight years after adoption day (or the IAEA reaching its broader conclusion on Iran's nuclear program, whichever is sooner). Adoption day triggers the UN to lift missile restrictions, Iran to seek ratification of its additional protocol, the EU to terminate all remaining nuclear sanctions, United States to remove certain entities from the sanctioned list, and the United States to seek legislative termination of certain sanctions.
  • October 2025, Termination Day: Ten years after adoption day. Termination day terminates Resolution 2231 and the Security Council closes Iran's nuclear file.
