Israel’s permanent representative to the International Atomic Energy Agency (IAEA) and Comprehensive Test Ban Treaty Organization (CTBTO), Merav Zafary-Odiz said “a regional moratorium [on nuclear testing] could enhance security, and potentially lead to a future ratification of the CTBT. Israel has announced its commitment to a moratorium, it would be useful for others to do the same.” Zafary-Odiz’s statement came during a Jan. 27 panel at the CTBTO’s Symposium on “Science and Diplomacy for Peace and Security” in Vienna. She also noted that a region-wide test ban would enhance security…

Iran, P5+1 Mark Deal Implementation Day Iranian Foreign Minister Javad Zarif and EU High Representative Federica Mogherini announced on Jan. 16 that the International Atomic Energy Agency (IAEA) verified that Tehran completed its nuclear commitments under the July 14 nuclear deal. The agency’s verification triggered “implementation day” according to the nuclear deal, known as the Joint Comprehensive Plan of Action, between Iran and the P5+1 (China, France, Germany, Russia, the United Kingdom and the United States). On implementation day, nuclear-related sanctions on Iran imposed by the United…

In 2009, the Arms Control Association launched this project to help disseminate information, ideas, and analysis about the “longest-sought, hardest-fought prize” in arms control—the Comprehensive Test Ban Treaty (CTBT)—and the steps to bring it into force. Since then, we’ve seen progress in many areas, including: ratification of the treaty by key states; preparations by key states, including the United States, to bring the treaty to a vote on ratification; and continued progress by the Comprehensive Test Ban Treaty Organization (CTBTO) to monitor and verify compliance. At the same time,…

On January 16, EU High Representative Federica Mogherini and Iranian Foreign Minister Mohammad Javad Zarif announced that Tehran completed its nuclear-related commitments under the July 2015 nuclear agreement and sanctions were lifted accordingly. Zaif and Mogherini said that “proper implementation will be a key contribution to improved regional and international peace, stability and security.” The arrival of implementation day of the 2015 nuclear deal with Iran, known as the Joint Comprehensive Plan of Action, marks a historic milestone in the process to block Iran’s pathways to a nuclear…

Referred to as the “Merchant of Death,” Viktor Bout provided weapons to some of the world’s deadliest conflicts for more than 20 years. Used by governments large and small, rebel groups, and other undesirable actors, Bout’s name is synonymous with the shadowy world of international arms brokers.  Though Bout came to represent the dark underpinnings of the global arms trade, a recent documentary provides a somewhat more intimate view of his global enterprise. Based primarily upon footage from Bout’s home video collection, The Notorious Mr. Bout gives viewers a glimpse of the man, husband,…

On Jan. 6, North Korea conducted its fourth underground nuclear weapons test explosion. The government in Pyongyang claims it conducted a successful test that “scientifically verified the power” of a small hydrogen bomb. The statement claims that the test signifies a “higher stage” of development of North Korea’s nuclear force. Initial readings from seismic stations in the region, however, strongly suggest the yield of the blast was slightly smaller than the February 2013 nuclear test. According to the Vienna-based Comprehensive Test Ban Treaty Organization (CTBTO), the “initial location…

(Updated January 19, 2016 to reflect the revised magnitude estimate.) North Korea claims it has conducted a fourth nuclear weapons test explosion and early readings from seismic stations in the region strongly suggest a relatively low-yield underground nuclear test was conducted. According to the Vienna-based Comprehensive Test Ban Treaty Organization (CTBTO), the “initial location estimate” of the seismic activity shows that the event took place in the area of North Korea’s nuclear test site, Punggye-ri, which is located in the northeast of the country. The test has been universally…

Iran’s recent ballistic missile tests, while extremely unhelpful, should not come as a surprise. And although the missile tests violate UN Security Council Resolution 1929, they are not a violation of the soon-to-be-implemented nuclear deal between six world powers and Iran. There should be consequences for violations of Security Council resolutions. However, U.S. policymakers should put the risks posed by the missile tests in perspective and pursue effective actions that address the violation, but do not undermine progress toward reducing Iran’s nuclear potential. Despite the passage of UN…

The International Atomic Energy Agency’s (IAEA) Board of Governors voted unanimously Dec. 15 to close the agency’s investigation into Iran’s past weaponization work. The Board also took the important step of instructing the IAEA to rigorously pursue any concerns about Iran’s nuclear activities that might arise in the future. The Board’s decision to close Iran’s file was hardly a surprise. The Dec. 2 report from IAEA Director General Yukiya Amano determining that Iran pursued a nuclear weapons program prior to 2003, and conducted periodic activities leading up until 2009, largely fit with…

This past October, Undersecretary of State for Arms Control and International Security Rose Gottemoeller visited several states where the United States conducted some of the 1,030 nuclear weapons test explosion before the end of nuclear weapons testing in September 1992. Her mission: to speak about the enduring value of the 1996 Comprehensive Test Ban Treaty (CTBT)—which the United States was the first to sign but is still among the last few that has not yet ratified. Undersecretary Gottemoeller’s tour did not begin and end in Nevada, where the United States conducted 921 nuclear test…
