In 1960, at the age of 43, John F. Kennedy became the youngest elected President in U.S. history, during a period of growing tensions in the U.S.-Soviet Cold War rivalry. Soon after taking office in 1961, he authorized the “Bay of Pigs” invasion led by the CIA and exiles from Cuba, whose government had been overthrown by communist rebels in 1959. This failed to overthrow leader Fidel Castro, and was a major embarrassment to Kennedy. Tensions with the Soviet Union further escalated during the 1961 Berlin Crisis. These events set the stage for the Cuban Missile Crisis. On October 15, 1962 Kennedy was informed of the discovery of Soviet missiles in Cuba and called a meeting of a small circle of trusted advisors (known as the Executive Committee of the National Security Council, or ExComm). He resisted pressure to react quickly with a surprise air strike, and took time to deliberate in secret on the possible courses of action. On October 22 the President announced a naval blockade on further arms shipments to Cuba. He then worked out an agreement with the Soviets, which involved a U.S. pledge not to invade Cuba if the Soviet Union withdrew its missiles, a threat to attack within 24 hours if the offer wasn’t accepted, and a secret promise to withdraw U.S. missiles from Turkey in four-five months.
