These more than 350 recently declassified documents from archives of former Warsaw Pact countries and the U.S. reveal previously hidden aspects of Cold War military strategy. The project offers documents and accompanying analyses in six categories: Warsaw Pact records; Warsaw Pact war plans; NATO records (U.S. and British); national perspectives (Bulgaria, Romania, Hungary, China, and Poland); crises (Berlin and Libya); and intelligence.

The website also provides 13 oral history interviews with former officials, including two Eisenhower administration officers involved with NATO planning and nuclear weapons policies. Documents reveal a 1964 Warsaw Pact war plan for using nuclear weapons in a preemptive strike against NATO forces and a 1965 Hungarian Army exercise detailing the targeted destruction of Western cities, including Vienna, Munich, Verona, and Vicenza. A 30-page survey article assesses the new history written since the release of recent documents.
