Kennedy was in Seattle and scheduled to attend the Seattle Century 21 World’s Fair when his press secretary announced that he had contracted an “upper respiratory infection.” The president then flew back to Washington, where he supposedly went to bed to recover from his cold.

Four days earlier, Kennedy had seen photographic proof that the Soviets were building 40 ballistic missile sites on the island of Cuba—within striking distance of the United States. Kennedy’s supposed bed rest was actually a marathon secret session with advisors to decide upon a response to the Soviet action. The group believed that Kennedy had three choices: to negotiate with the Russians to remove the missiles; to bomb the missile sites in Cuba; or implement a naval blockade of the island. Kennedy chose to blockade Cuba, deciding to bomb the missile sites only if further action proved necessary.
The blockade began October 21 and, the next day, Kennedy delivered a public address alerting Americans to the situation and calling on Soviet Premier Nikita Khrushchev to remove the missiles or face retaliation by the United States. Khrushchev responded by sending more ships—possibly carrying military cargo—toward Cuba and allowing construction at the sites to continue. Over the following six days, the Cuban Missile Crisis, as it is now known, brought the world to the brink of global nuclear war while the two leaders engaged in tense negotiations via telegram and letter.
By October 28, Kennedy and Khrushchev had reached a settlement and people on both sides of the conflict breathed a collective but wary sigh of relief. The Cuban missile sites were dismantled and, in return, Kennedy agreed to close U.S. missile sites in Turkey.
