In October 1962, the U.S. government learned that the Soviet Union was building nuclear-missile bases in Cuba, well within range of the United States. President John F. Kennedy responded by imposing a naval blockade to prevent more missiles from reaching the island nation. For several days, it was not clear how the Soviets would react if U.S. ships tried to stop a Soviet ship at sea. Eventually, the Soviets backed down and agreed to remove the missiles from Cuba.
