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 spectre through the Nuclear Non-proliferation Treaty of 1970, the Nuclear Non-proliferation Act of 1978 (P.L. 95-242), the Nunn-Lugar Co-operative 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 centre for Non-proliferation Studies. In the wake of the September 11 attack, the nuclear threat has taken a new urgency. This book addresses potential terrorist capabilities.
