Kennedy went on television on October 22, 1962. He told the country that Soviet missile bases were being built in Cuba, ninety miles from Florida, and that he had ordered a naval quarantine to stop more weapons from arriving. The world held its breath.
The missiles were found by photographs. The pictures showed it. U-2 spy planes had brought back pictures of launch sites under construction, and the evidence was placed before Kennedy days before he spoke. He and his advisers spent a week in secret weighing the options, from air strikes to invasion.
He chose the quarantine. It was less than war but more than protest, a line drawn at sea that Soviet ships would have to cross or turn back. Kennedy demanded that the missiles already in Cuba be dismantled and removed, and he warned that any nuclear attack from the island would be met with a full response.
The next days were the most dangerous of the Cold War. Soviet ships steamed toward the quarantine line, and the two superpowers came closer to nuclear exchange than at any time before or since. The crisis ended when Khrushchev agreed to withdraw the missiles in exchange for a pledge not to invade Cuba and a quiet deal over American missiles in Turkey.
The speech marked the peak of the confrontation. It showed a president laying out a crisis to his people in plain terms, and it made the nuclear danger something every family could see. The world survived those thirteen days, but only just.
