The Cuban Missile Crisis

In October 1962, American U-2 reconnaissance flights discovered that the Soviet Union was secretly installing nuclear missiles in Cuba, within striking distance of much of the United States. The resulting thirteen-day standoff is widely considered the closest the Cold War ever came to nuclear war. The discovery came less than a year after the failed Bay of Pigs invasion, which had pushed Havana to seek Soviet military protection.

President Kennedy and his advisers weighed an air strike and invasion before settling on a naval “quarantine” — a blockade to stop further Soviet shipments — while demanding the missiles' removal. For nearly two weeks the world held its breath as Soviet ships approached the quarantine line and a U.S. aircraft was shot down over Cuba. The crisis was resolved when the Soviets agreed to withdraw the missiles in exchange for a public U.S. pledge not to invade Cuba and a secret agreement to remove American Jupiter missiles from Turkey.

Fidel Castro, who had urged Soviet leader Nikita Khrushchev toward a hard line, was infuriated to be excluded from the superpower negotiations that decided his country's fate — a stark reminder that Cuba had become a pawn in a contest between Moscow and Washington. The episode deepened the island's dependence on the Soviet Union, which would underwrite the Cuban economy for the next three decades.

For the wider world, the crisis became the defining lesson in nuclear brinkmanship and led directly to the Moscow–Washington hotline and later arms-control talks. For Cubans, it cemented their island's role as a Cold War flashpoint and tied its fortunes ever more tightly to a distant patron whose eventual collapse would bring devastating hardship.
