The authors offer three insights from Ukraine's path to denuclearization that may help deal with today’s proliferation challenges.

The timeline below was compiled by Simon Saradzhyan and Mariana Budjeryn and the foreword was written by William Tobey (author bios below). As an accompaniment, Ms. Budjeryn has also interviewed Sam Nunn, the former senator whose efforts were key to securing U.S. funding to help a disintegrating Soviet Union dismantle and safeguard its nuclear weapons. The timeline authors would like to thank former RM student associate Andre Gellerman for his research support and Susan Koch for her insightful comments. This is an evolving draft, produced in cooperation with the U.S.-Russia Initiative to Prevent Nuclear Terrorism at Harvard's Belfer Center for Science and International Affairs and with support from the center's Managing the Atom Project. A bibliography can be found at the bottom of the page.

"Ukraine's denuclearization had been a controversial issue even as it was negotiated, leaving bitter traces in the country's political and public discourse. As a student of political science in Kyiv in the mid-1990s, I remember being outraged by the sense of injustice: how could the states that rely on their own nuclear deterrents demand the nuclear disarmament of others? More so that one of these states, Russia, has never fully come to terms with Ukraine's independence. Since then, I came to research a doctoral dissertation on the denuclearization of post-Soviet successor states and, in the process, learned a great deal about Ukraine's nuclear disarmament that dispelled many of my preconceptions."
