In trying to prevent adversaries from acquiring new military capabilities, countries often employ strategies of arms denial; e.g., “unilateral diplomacy,” supply chain interdiction, covert sabotage, and targeted military strikes. Using a game-theoretical model of weapons acquisition and denial, the authors posit that the prevalence of this approach gives rise to strategic effects that affect all players’ behavior.

In the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.

There has been much speculation as to what might replace the Nuclear Security Summits after 2016. One candidate touted as a suitable inheritor of the summits’ mantle is the International Atomic Energy Agency. In this discussion paper, Trevor Findlay examines whether and to what extent the IAEA could and should do so, what form its role might take, and how the Agency and summiteers might prepare for such an eventuality.

The Belfer Center’s Eben Harrell and Pulitzer Prize-winning author David E. Hoffman for the first time report the details of one of the largest nuclear security operations of the post-Cold War years — a  secret 17-year, $150 million operation to secure plutonium in the tunnels of Degelen Mountain.

A long-standing goal of diplomacy with Iran is persuading Iran to suspend its enrichment operations while it clarifies its past activities and while negotiations proceed on a more permanent resolution to the nuclear crisis. However, there is problem in using suspension of nuclear material production as a negotiating step: The technical details of suspension have never been clearly defined. The international community needs to be aware of the diversion risks during a suspension of enrichment activities and should mitigate these risks by including the necessary verification measures during negotiations and signing of any agreement on suspension.

Despite substantial progress in improving nuclear security in recent years, there is more to be done.  The threats of nuclear theft and terrorism remain very real.  This paper recommends learning from the much stronger national and international efforts in nuclear safety, and in particular taking steps to build international understanding of the threat; establish effective performance objectives; assure performance; train and certify needed personnel; build security culture and exchange best practices; reduce the number of sites that need to be protected; and strengthen the international framework and continue the dialogue once leaders are no longer meeting regularly at the summit level.

"Is Pakistan collapsing? How far are the Taliban from Islamabad? Can al-Qaeda grab the country's nuclear weapons? These are the types of questions raised every day by the American media, academia and policy circles. And these are critical issues, given the nature of the evolving crisis in Pakistan. The approximately two dozen suicide bombings in 2009 so far, 66 in 2008, and 61 in 2007, all of which have targeted armed forces personnel, police, politicians, and ordinary people not only in the country's turbulent northwest but also in its major urban centers, indicate the seriousness of the threat. A major ammunition factory area located close to some very sensitive nuclear installations in Wah (Punjab) was targeted by two suicide bombers in August 2008, an act that sent shudders across the country's security establishment...."

"The efforts that the Center has made in addressing the nuclear challenges of the post-Cold War era are anchored in the books that it has produced on the major dimensions of the problem."

Matthew Bunn and Anthony Wier find that although threat reduction funding has had dramatic effects in reducing the risk of nuclear terrorism, the Bush administration’s proposed FY 2008 budget for cooperative threat reduction would reduce the overall funds available.  They propose a number of remedies, some of which have been taken up by congress in the appropriations process.

Matthew Bunn argues that placing the centrifuges at Natanz in one of two "standby" modes offered a way out of the current stand-off over suspension.
