 On June 12, 1982, more than 750,000 protesters marched from the U.N. headquarters building to Central Park in New York to call for a Nuclear Freeze.The public accepted the technological certainty of nuclear war, but did not have faith in nuclear defence.Tensions came to a head with the NATO exercise Able Archer 83, which, combined with other events such as President Reagan's "Evil Empire" speech and the deployment of the Pershing II missile in Western Europe, as well as the erroneous Soviet shoot-down of Korean Air Lines Flight 007, had the Soviets frantically convinced that the West was about to launch an all-out war against the USSR.
