Today marks the 30th anniversary of the beginning of Able Archer 83, a NATO exercise that utilized “new nuclear weapons release procedures” to simulate the transition from conventional to nuclear war with the Soviet Union. Although US officials saw Able Archer 83 as a routine exercise, it resulted in an “unprecedented Soviet reaction” which US intelligence eventually inferred “was an expression of a genuine belief on the part of Soviet leaders that US was planning a nuclear first strike,” according to the largest collection of declassified documents on the 1983 War Scare compiled and posted by the National Security Archive, www.nsarchive.org.
