Secret intelligence is the "missing dimension" of Cold War history, as it is of most diplomatic history. This course analyzes a selective history of the U.S. intelligence community in the Cold War in order to assess its overall role. On the basis of declassified intelligence records and eyewitness accounts of former senior intelligence officers, the course focuses on what the intelligence community collected, knew, and estimated, and how intelligence reporting did or did not affect U.S. national security strategy and policy. The course concludes by examining U.S. intelligence in the post-Cold War period.
