Many believe that terrorists could cause more deaths and destruction with nuclear weapons than by any other means. The United States and the world community have tried for decades to avoid that specter through the Nuclear Nonproliferation Treaty of 1970, the Nuclear Nonproliferation Act of 1978 (P.L. 95-242), the Nunn-Lugar Cooperative Threat Reduction Program, and many other measures. Many have called the attention to the problem; websites with current resources include the Nuclear Control Institute, the Carnegie Endowment for International Peace, and the center for Nonproliferation Studies. In the wake of the September 11 attack, the nuclear threat has taken a new urgency. This book addresses potential terrorist capabilities.
