The Silent Front: Spies and Secrets of the Cold War | Extra Long Documentary

During the Cold War, spies and military observers from both the West and the Soviet bloc operated extensively, with East Germany as a focal point for Western intelligence to closely monitor Soviet military activities. In the 1980s, as the Soviet army modernized, tensions peaked, particularly in 1983 when NATO's nuclear release drills alarmed Moscow. The documentary reveals a complex web of espionage, including a mole within the Allies, and explores whether this intelligence warfare contributed to keeping the Cold War from turning hot.
