Nuclear weapons have transformed international politics. While we all live under the shadow of nuclear annihilation we also al enjoy an international system that has been free of great power war for over 65 years, a fact that some analysts argue is partially due to the efficacy of nuclear deterrence. New fears of proliferation and terrorism make the issue of weapons one of enduring importance. This course examines the meaning of the 'nuclear revolution,' why states seek or forgo nuclear weapons, the history and logic of nuclear strategy, and efforts to limit the spread of these weapons. Among the cases examined in the course are the US and the USSR in the Cold War, Argentina, Brazil, China, India, Israel, North Korea, Pakistan, and South Africa.
