Curbing nuclear weapons has never been a more urgent priority for nations both great and small, but the global system of nuclear controls seems paralyzed. Have the instruments that once worked so well lost their efficacy? What can be done to clear the obstructions and break this impasse? In this volume, some of the world’s most recognized thinkers on nuclear issues take on these questions. Can the market be harnessed as an early warning system for identifying risky nuclear behavior? Is an international fuel bank a solution against nuclear proliferation, or a Trojan horse opening the door to it? What hidden roadblocks might derail the India/U.S. nuclear deal? Is the era of arms control over, or will the new proliferation threats help nuclear disarmament find a place on the policy table? Readers who are new to the field, and those who are steeped in it, will find penetrating insights into today’s nuclear challenges—and a glimpse of the road ahead. The contributors to the volume include: Hans Blix, chairman of the Weapons of Mass Destruction Commission; Christopher F. Chyba, professor of astrophysical sciences and international affairs at the Woodrow Wilson School, Princeton University; Joseph Cirincione, senior fellow and director for nuclear policy at the Center for American Progress; Jayantha Dhanapala, former UN under-secretary-general for disarmament affairs from 1998 to 2003 and the president of the 1995 NPT Review and Extension Conference; Michael Krepon, cofounder of the Henry L. Stimson Center; William C. Potter, director of the Center for Nonproliferation Studies at the Monterey Institute of International Studies; and Henry D. Sokolski, executive director of the Nonproliferation Policy Education Center.
