In the movie "Thirteen Days," several references are made to Munich. Transcripts of the Executive Committee of the National Security Council (ExCom) show that the Munich analogy was used constantly by the government in their discussions regarding the Cuban Missile Crisis.
The analogy refers to the Munich Agreement of 1938, widely known as a failure in appeasement. This event had a particular meaning for Kennedy, as his father, Joseph Kennedy, had been Roosevelt's ambassador to Britain at the time of the conference.
