Answer

1983. On September 26, 1983, a Soviet early warning system falsely detected a U.S. nuclear missile attack. The incident was caused by a combination of human error and a software glitch. The Soviet military was on high alert for several minutes before the mistake was discovered. The incident highlighted the dangers of nuclear weapons and the importance of preventing accidental nuclear war.
