Nuclear deterrence thinking has become so entrenched in U.S. academic and policy circles that it only seems natural that other states regard nuclear weapons in the same terms. Yet is it necessarily so? In this working paper, Polina Sinovets and Mariana Budjeryn examine the case of Ukraine to understand how its leaders interpreted the value of the nuclear weapons deployed on Ukrainian territory in 1990–1994.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

As early as the end of the Second World War it was recognized that nuclear fuel cycle technologies developed for military purposes—specifically, uranium enrichment and reprocessing—had major potential for peaceful applications but remained inherently dual-purpose, and if not controlled appropriately, could be diverted to military use. The very first issue considered by the newly founded United Nations was “the problems raised by the discovery of atomic energy.”

In this new report, Trevor Findlay provides the first comprehensive study of the IAEA's handling of states not complying with their non-proliferation obligations. The report finds that none of the cases have followed the non-compliance process outlined in the Agency's Statute and safeguards agreements. Rather, each case has posed unique challenges to the non-proliferation regime. The report concludes that creativity and deft statecraft are key to the handling of complex non-compliance cases.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."

The Iran Nuclear Deal: A Definitive Guide has been produced in the interest of contributing to informed Congressional review and public discourse on a comprehensive nuclear agreement with Iran—the Joint Comprehensive Plan of Action (JCPOA). It provides a concise description of the agreement and the accompanying UN Security Council Resolution 2231. It also includes a balanced assessment of the agreement's strengths and weaknesses with respect to its central objective to prevent Iran from acquiring nuclear weapons.

To assist Members of Congress and observers in analyzing these issues and judging a potential comprehensive agreement, the Belfer Center prepared this brief to outline the key facets of sanctions against Iran. Written as an addendum to our April policy brief, ‘Decoding the Iran Nuclear Deal,’ this report is driven by the policy debate’s leading questions.

As nuclear negotiations with Iran near their final stage, the question of inspections has come to the fore. If a final agreement is reached, inspections will be a principal means of assuring that Iran does not develop nuclear weapons, either by “breakout” at declared facilities, or by “sneakout” using secret sites. Given the importance being placed on inspections, what type will be necessary?  What inspection and verification regime will be needed to facilitate compliance, detect violations, and ensure effective enforcement?
