The threat posed by the proliferation of weapons of mass destruction (WMD) continues to grow. The possibility of deliberate or accidental use of those weapons by governments remains uncomfortably high. The growing stockpiles of nuclear materials and the diffusion of related technology and know-how make the prospect of WMD use by nonstate actors appallingly real. It is with good reason that nonproliferation now tops most lists of national security concerns.
