The course reviews the history of the Cold War in light of formerly-secret archival documents. Examples include the US White House Tapes and Venona decrypts; massive declassification of records in the ex-Soviet bloc; and parallel developments in China, Cuba, and other Communist states. Archival discoveries have cast new light, not just on individual episodes (e.g., Cuban Missile Crisis of 1962, Soviet invasion of Afghanistan in 1979) but on the origins, strategies, and driving forces of this 45-year conflict. The focus will be mainly on the superpowers and their alliance systems.
