Able Archer 83: The Origin

In 1983, George devised a 10-day NATO exercise to simulate World War 3, so that all nations participating could see what would happen in the worst case scenario of war. Unfortunately, Neal forgot to tell the Soviet Union about George's game/simulation, resulting in wide-spread Soviet panic and the closest the world has ever come to nuclear war. (Wikipedia: Able Archer 83). Whoops. Neal's bad.
