This month is the 50th anniversary of the Cuban Missile Crisis (October 16-28, 1962), so we're going to hear a great deal about the weeks when the world almost died. But the past is a foreign country, a place where everything was in black-and-white and men still wore hats, so it's just scary stories about a long-gone time. Or so it seems.
The outlines of the tale are well known. It was 17 years since the United States had used nuclear weapons on Japan, and the Soviet Union now had them too. Lots of them: the American and Soviet arsenals included some 30,000 nuclear weapons, and not all of them were carried by bombers any more. Some were mounted on rockets that could reach their targets in the other country in half an hour.
Both Washington and Moscow therefore had some version of a "launch on warning" policy: if you think the other side's missiles are inbound, launch your own missiles before you lose them. There couldn't be a more hair-trigger situation than that, you might think - but then things got a lot worse.
At the start of the 1960s, Moscow had gained a new Communist ally in Fidel Castro, but the United States kept talking about invading Cuba. So Soviet Premier Nikita Khrushchev moved some nuclear-tipped missiles to Cuba to deter the United States from attacking the island. However, from Cuba the Soviet missiles would be only five minutes away from their American targets. That caused panic in Washington.
Early in October, 1962 the first Soviet SS-4 missiles arrived in Cuba, and American U-2 spy planes discovered them almost at once. President John F. Kennedy knew about them by October 16, but he did not go on television and warn the American public of the risk of nuclear war until the 22nd.
