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…

For a propaganda state reliant on a state-sanctioned image to indoctrinate its people and promote a certain reputation globally, a successful missile test is an event to be photographed and celebrated in the state-run news. Today, the North Korean leader Kim Jong Un announced that his state has developed a hydrogen bomb, a new claim that has elicited skepticism from experts. This decree, like its many other public pronouncements and demonstrations of military equipment, does not necessarily reflect North Korea’s true current capability. Pyongyang meticulously crafts its own nuclear narrative…

The IAEA PMD Report Is Out The International Atomic Energy Agency (IAEA) released its long-awaited report on Iran’s past activities in twelve areas related to nuclear weapons development, the so-called possible military dimensions (PMD) of Iran’s nuclear program. The Dec. 2 report assessed that Iran conducted a coordinated “range of activities relevant to the development of a nuclear explosive device” prior to the end of 2003 and some of the activities continued between 2003-2009. According to the assessment the “activities did not advance beyond feasibility and scientific studies, and the…

According to the Nov. 18 International Atomic Energy Agency’s (IAEA) quarterly report, Iran has dismantled 4,530 centrifuges since the July 14 Joint Comprehensive Plan of Action was adopted last month. Action by Iran to fulfill its commitments under the agreement is a positive sign. Completing the dismantlement of 1/3 of the ~13,500 centrifuges that must be removed under the terms of the deal is tangible evidence that the agreement is working to stringently restrict Iran’s nuclear program.   The IAEA also reported that it began preparatory activities to implement the increased monitoring and…

And the Dismantlement Begins Iran has begun dismantling centrifuges at its Natanz facility to meet the terms set by the July 14 Joint Comprehensive Plan of Action, according to comments from Ali Akbar Salehi, head of the Atomic Energy Organization of Iran, on Nov. 15. The centrifuges being removed are inactive and not being used to enrich uranium, Salehi said. Iran has about 15,750 first generation centrifuges at its Natanz plant, of which about 9,500 are enriching uranium. Under the July 14 deal between Iran and the P5+1 (China, France, Germany, Russia, United Kingdom, and United States),…

In April 2007, a shipment of sodium perchlorate bound for Iran was detoured to an Asian port and then returned to the country of origin. Six months earlier, in November 2006, a shipment of chromium-nickel steel plates were interdicted en route to Iran and returned to the supplier country. Both materials can be used for the development of ballistic missiles and were shipped to Iran in contravention of UN Security Council resolutions. These two cases epitomize the achievements of the Proliferation Security Initiative (PSI), which has been instrumental in identifying and interrupting numerous…

International relations with North Korea have been marked by provocations, off-and-on diplomatic engagement, and the threat of military conflict for decades. The threats posed by North Korea’s nuclear and missile programs came back into the spotlight this fall with talk from North Korea that it would soon conduct a fourth satellite launch, which has not been delivered upon to date, the highly anticipated military parade in honor of the Korean Workers’ Party 70th anniversary, and reports that Pyongyang is making preparations for a fourth nuclear test explosion.   It is Pyongyang itself that…
