Able Archer 83
에이블 아처 83
A NATO command post exercise held in November 1983 that simulated nuclear war procedures across Western Europe. Its heightened realism (new encryption codes, radio silence, and heads-of-government participation) led the Soviet military leadership to mistake it for cover for a genuine nuclear first strike; in response, Soviet air forces in East Germany and Poland were placed on alert and nuclear warheads were loaded onto combat aircraft. Widely regarded as one of the closest moments the world came to nuclear war since the Cuban Missile Crisis, the scare galvanized US-Soviet arms control efforts and helped spur Reagan's turn toward dialogue.
