FOR ALMOST half a century, the world's most powerful nuclear states have been locked in a military stalemate known as mutual assured destruction (MAD). By the early 196os, the nuclear arsenals ofthe United States and the Soviet Union had grown so large and sophisticated that neither country could entirely destroy the other's retaliatory force by launching first, even with a surprise attack. Starting a nuclear war was therefore tantamount to committing suicide. During the Cold War, many scholars and policy analysts believed that MAD made the world relatively stable and peaceful because it induced great caution in international politics, discouraged the use of nuclear threats to resolve disputes, and generally restrained the superpowers' behavior. (Revealingly, the last intense nuclear standoff, the 1962 Cuban missile crisis, occurred at the dawn of the era of MAD.) Because of the nuclear stalemate, the optimists argued, the era of intentional great-power wars had ended. Critics of MAD, however, argued that it prevented not great-power war but the rolling back of the power and influence of a dangerously expansionist and totalitarian Soviet Union. From that perspective, MAD prolonged the life of an evil empire.
