Nuclear Issues

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.

The U.S. achieved nonproliferation success against Taiwan in the 1970s and 1980s by forcing this highly dependent ally to accept intrusive on-site inspections that stopped its nuclear work. Taiwan depended on the U.S. for its very survival....Repeated military punishment threats against Taiwan's security (threat to abandon) and civilian nuclear program failed to change this ally's determination to acquire nuclear weapons. Success was achieved thanks to coercion by denial and dismantlement that uncovered and stopped Taipei's nuclear work.

This paper studies under what conditions the U.S. can coerce its allies to forgo nuclear weapons. Specifically, why did Taiwan and South Korea give up their nuclear pursuits under American duress, while Israel and Pakistan attained a nuclear capability?

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.

This report marks the culmination of a two-year research project that examined all aspects of the mandate and operations of the International Atomic Energy Agency, from major programs on safeguards, safety, security, and the peaceful uses of nuclear energy to governance, management, and finance.

Nearly all of the 190 signatories to the Nuclear Non-Proliferation Treaty (NPT) agree that the forty-two-year-old treaty is fragile and in need of fundamental reform. But gaining consensus on how to fix the NPT will require reconciling the sharply differing views of nuclear weapon states and non-nuclear weapon states. Strengthening the international rules is increasingly important as dozens of countries, including some with unstable political environments, explore nuclear energy. The result is an ever-increasing distribution of this technology. In this paper, Steven E. Miller outlines the main points of contention within the NPT regime and identifies the issues that have made reform so difficult.

"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...."
