John Fitzgerald "Jack" Kennedy was the 35th President of the United States. Kennedy was noted for his Cold War leadership, avoiding nuclear confrontation with the Soviet Union while advancing the cause of civil rights at home and setting a goal of a manned Moon landing by the end of the 1960s.
Meeting Doctor Manhattan
In 1961, Kennedy met the first real superhero, Doctor Manhattan outside the White House in Washington, D.C.. He asked him what it's like to be a superhero, to which Manhattan replied that JFK should already know and everyone laughed. That year, JFK kept silent his problems with Cuba and didn't ask for Manhattan's help.
On November 22, 1963, Kennedy was cut down by bullets as his motorcade approached downtown Dallas. Kennedy never gave the speech in Dallas in which he would refer to contemporary Americans being "the watchmen on the walls of world freedom." Kennedy died in Parkland Hospital, and his Vice-President, Lyndon B. Johnson, took office. Doctor Manhattan knew that Kennedy was going to be assassinated in Dallas, but felt it would be futile to try to prevent it, as it has already happened in Manhattan's altered awareness of time.
