Although there remains a residual case for retention of minimal nuclear weapons inventories among the nuclear states, and although some states (Israel, Pakistan) face security threats which go to their very survival and thus make weapons of last resort worth acquiring, the vast majority of the world's nuclear weapons are militarily worthless, and should be destroyed. There should also be a comprehensive test ban treaty.
The possibility that additional nations, or even terrorists, might get nuclear weapons has been a cause of deep anxiety ever since the first atomic weapon was exploded in 1945. It has been the subject of one important treaty (the Nuclear Non-Proliferation Treaty, or NPT) and more recently preventing proliferation was one of the central objectives of the Carter Administration, in an effort that generated intense controversy. Today an assessment of that effort is important because nuclear proliferation continues to be a most dangerous prospect in the coming decades_deserving of as much attention as the Soviet Union and the national security risks arising from dependence on foreign oil, as well as the basic economic problems of high inflation and low productivity.
