Historical context

Able Archer 83 was a NATO command post exercise in November 1983. Because it mimicked a nuclear release sequence, Soviet leadership—already paranoid about a preemptive Western strike—mistook the exercise for a genuine cover for a nuclear attack. It is considered one of the closest points the world came to nuclear war since the 1962 Cuban Missile Crisis.

Reading material

In 1983, the Cold War was at a freezing point. Relations between the USA and the USSR were incredibly tense. NATO held a training exercise called 'Able Archer 83'. It was meant to simulate military communication in the event of a nuclear escalation. However, the Soviet Union did not see it as just a drill. They feared that the West was using the exercise to disguise a real first strike. The world came dangerously close to a misunderstanding that could have triggered a global nuclear conflict. This event highlights how fragile peace is when trust between world powers completely breaks down.
