Cuban Missile Crisis

On October 16, 1962, President John F. Kennedy learned that the Soviet Union had secretly installed nuclear missiles in Cuba, just 90 miles off the Florida coast. The discovery came from U-2 spy plane photographs analyzed by the CIA, which revealed at least 40 medium-range ballistic missiles capable of striking major American cities. Kennedy faced an impossible choice: invade Cuba, bomb the missile sites, or find another way to remove the weapons without triggering a nuclear exchange that could kill millions.

For 13 days, the world held its breath. Kennedy established an "ExComm" advisory group including Secretary of Defense Robert McNamara, CIA Director John McCone, and Soviet expert George Kennan to weigh options. On October 22, Kennedy announced a naval blockade of Cuba to prevent Soviet supply ships from delivering additional weapons. Soviet Premier Nikita Khrushchev, who had authorized the missile deployment partly to protect Cuba from another U.S.-backed invasion attempt and partly to close the apparent "missile gap" favoring America, rejected the blockade as an act of war.

The crisis escalated with terrifying speed. Soviet ships steamed toward the American blockade line. U.S. military units went to DEFCON 2—the highest state of readiness short of actual war. B-47 and B-52 bombers armed with nuclear weapons flew constant patrol missions. An American U-2 pilot, Rudolf Anderson Jr., was shot down over Cuba on October 27, killed by a Soviet surface-to-air missile. That same day, a Soviet submarine commander believed the U.S. had begun attacking and came close to firing a nuclear torpedo at an American destroyer.

The breakthrough came through back-channel diplomacy. On October 26, Khrushchev sent a rambling letter suggesting he would remove the missiles if Kennedy pledged not to invade Cuba. The next day came a second, harder letter demanding the removal of American Jupiter missiles from Turkey. Kennedy's advisors, particularly his brother Robert F. Kennedy, the Attorney General, decided to ignore the second letter and respond to the first. The U.S. agreed publicly to the no-invasion pledge and privately committed to removing the Jupiter missiles from Turkey within months.

Khrushchev announced on October 28 that Soviet ships would return home and the missiles would be dismantled. The crisis ended not with triumph but with mutual recognition that nuclear weapons made victory impossible. The experience shook both superpowers. Within months, Kennedy and Khrushchev installed a hotline between the White House and the Kremlin so leaders could communicate directly during future crises. The Cuban Missile Crisis became the closest the world came to nuclear annihilation during the Cold War—and perhaps in human history.
