During the Cold War there were three years that stand out - periods in which tension was high and the world stood on the brink of nuclear conflagration. 1962 easily ranks first with the Cuban Missile Crisis. 1973 usually ranks second in connection to the Yom Kippur War and the US raising of the DefCon alert to an elevated '3' - signalling preparations for potential war. The DefCon was not raised by the Americans in 1983, but Moscow was on high alert and many consider it to be one of the most tense periods of the Cold War.
