1) The Cuban Missile Crisis was the Cold War's closest brush with nuclear war. The most dangerous moment of the Cuban Missile Crisis was the evening of Saturday, 27 October 1962, when the resolution of the crisis was to back down or to hold your ground. Soviet ships were sailing towards Cuba but didn't break the U.S naval blockade. The Soviet Union had nuclear missile bases in Cuba and they were becoming operational, and pressure increased on President Kennedy to do something to get them out of Cuba, especially after an plane was shot down over Cuba and its pilot killed. A letter from Soviet leader Nikita S. Khrushchev arrived Saturday morning demanding that the United States agree to remove its Jupiter missiles from Turkey in exchange for a Soviet removal of missiles from Cuba. This demand confused the U.S. because prior letters only wanted the U.S. to promise not to invade Cuba. .
On Saturday evening, after a day of tense discussions within the Presidents senior advisers, President Kennedy decided to accept the terms of Khrushchev's October 26 letter (a U.S. non-invasion pledge in exchange for the verifiable departure of Soviet nuclear missiles). with private assurances to Khrushchev that the United States would speedily take out its missiles from Turkey, but only on the basis of a secret understanding, not as an open agreement that would appear to the public, and to NATO allies, as a concession to blackmail. The U.S. president elected to transmit this sensitive message through his brother, Attorney General Robert F. Kennedy, who met in his office at the Justice Department with Soviet ambassador Anatoly Dobrynin. .
2) The University of California of Berkeley students were fighting for their First Amendment right of free speech and free press.

In an attempt to limit that behavior the University prohibited pamphlets and propaganda from the campus.
