Deterrence or Defense?
"Speak softly and carry a big stick." President Theodore Roosevelt Nuclear missiles were recognized as a threat as early as 1945 at the dawn of the nuclear age. In 1972 the Anti-Ballistic Missile Treaty was signed. In it the US and USSR agreed to rely only on offensive forces to deter attacks.	"Today's world requires a new policy." President George W. Bush Intercontinental ballistic missiles were first deployed in 1958. In succeeding years both the US and USSR built thousands of these weapons. In 2002 the United States withdrew from the ABM Treaty and announced plans to build missile defenses.
For more than 50 years, deterrence has been the policy of the nuclear powers. Is it time for a new policy? Can defenses stop nuclear attacks? The simulation on these pages is designed to help answer these questions. Simulate an attack, using scenarios of your choice. Decide for yourself whether the best policy is deterrence or defense.
