Cuban Missile Crisis

The Cuban Missile Crisis of October 1962 was a 13-day confrontation between the United States and the Soviet Union over the deployment of nuclear missiles in Cuba—widely regarded as the closest the Cold War came to escalating into a full-scale nuclear war.1

Background and Soviet motives

The crisis emerged from Cold War tensions following the failed Bay of Pigs invasion in 1961 and the ongoing Berlin Crisis. Soviet Premier Nikita Khrushchev sought to counter the U.S. nuclear advantage—America had roughly 5,000 warheads to the Soviet Union's 300—and to protect Cuba from another U.S.-backed invasion.2 In May 1962, Khrushchev proposed placing medium- and intermediate-range missiles in Cuba, a plan approved by Cuban leader Fidel Castro, who saw it as a deterrent against U.S. aggression. The operation, codenamed Anadyr, secretly shipped over 40,000 Soviet troops and equipment to the island, despite U.S. intelligence warnings that such a move would be unacceptable.

Discovery and quarantine

On October 14, 1962, a U-2 spy plane photographed Soviet SS-4 medium-range ballistic missile sites under construction in San Cristóbal, Cuba. President John F. Kennedy convened the Executive Committee (ExComm) of the National Security Council to debate options, ranging from airstrikes to invasion. On October 22, Kennedy announced a naval "quarantine" of Cuba, a carefully chosen term to avoid the legal implications of a blockade, and demanded the removal of the missiles.3 The quarantine was enforced by U.S. Navy ships, and Soviet vessels bound for Cuba turned back, but the crisis escalated when a U-2 was shot down over Cuba on October 27, killing pilot Major Rudolf Anderson—the only U.S. combat fatality of the crisis.

Resolution and secret diplomacy

Behind the scenes, Kennedy and Khrushchev exchanged letters, with the crisis reaching its peak on "Black Saturday," October 27, when a Soviet submarine nearly launched a nuclear torpedo in response to depth charges from U.S. destroyers. The breakthrough came through a secret backchannel: Attorney General Robert Kennedy met with Soviet Ambassador Anatoly Dobrynin, agreeing to a public pledge not to invade Cuba and a private promise to remove U.S. Jupiter missiles from Turkey. On October 28, Khrushchev announced the withdrawal of Soviet missiles, and the crisis ended peacefully. The secret Turkey deal remained classified for years, and the crisis led to the establishment of the Moscow–Washington hotline in 1963 to improve crisis communication.

Lesser-known aspects

Several lesser-known dimensions enrich the story. The Soviet submarine B-59, commanded by Vasily Arkhipov, famously refused to authorize a nuclear launch, averted disaster—an act later celebrated as "the man who saved the world." The crisis also involved a U-2 flight over the Arctic that strayed into Soviet airspace, nearly triggering a response. Additionally, the U.S. had secretly deployed 80 nuclear-armed Jupiter missiles to Italy and Turkey, which were part of the trade. The crisis accelerated the Nuclear Test Ban Treaty of 1963 and prompted the U.S. to improve its satellite reconnaissance, leading to the development of the KH-7 Gambit system. The term "quarantine" was a legal innovation, and the crisis was the first time the U.S. and USSR used the "hotline"—though it was not yet installed, so messages were sent via teletype through the U.S. Embassy in Moscow.
