In a televised speech of extraordinary gravity, President John F.
Kennedy announced on October 22, 1962 that U.S. spy planes
had discovered Soviet missile bases in Cuba. These missile
sites—under construction but nearing completion—housed
medium-range missiles capable of striking a number of major
cities in the United States, including Washington, D.C.

Kennedy announced that he was ordering a naval “quarantine”
of Cuba to prevent Soviet ships from transporting any more
offensive weapons to the island and explained that the United
States would not tolerate the existence of the missile sites
currently in place. The president made it clear that America
would not stop short of military action to end what he called a “clandestine, reckless and provocative threat to world peace.”

What is known as the Cuban Missile Crisis actually began on
October 14, 1962—the day that U.S. intelligence personnel
analyzing U-2 spy plane data discovered that the Soviets were
building medium-range missile sites in Cuba.
