Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)

A paranoid U.S. Air Force General, Jack D. Ripper, orders a nuclear strike on the Soviet Union, convinced that communists are contaminating America's "precious bodily fluids." With communication cut off, only Ripper knows the recall code for the bombers, and his executive officer must find a way to stop the attack. Meanwhile, in the Pentagon’s War Room, President Muffley and his advisors scramble to prevent nuclear Armageddon.
