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.

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.

In the Foreword to this paper by Andrei Kokoshin, Belfer Center Director Graham Allison writes: "The global nuclear order is reaching a tipping point. Several trends are advancing along crooked paths, each undermining this order. These trends include North Korea’s expanding nuclear weapons program, Iran’s continuing nuclear ambitions, Pakistan’s increasing instability, growing doubts about the sustainability of the nonproliferation regime in general, and terrorist groups’ enduring aspirations to acquire nuclear weapons. Andrei Kokoshin, deputy of the State Duma and former secretary of Russia’s Security Council, analyzes these challenges that threaten to cause the nuclear order to collapse in the following paper."

"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...."
