Cuban Missile Crisis missiles already on the island. At 3:00 pm EDT on October 22, President Kennedy formally established the Executive Committee (EXCOMM) with National Security Action Memorandum (NSAM) 196. At 5:00 pm, he met with Congressional leaders who contentiously opposed a blockade and demanded a stronger response. In Moscow, Ambassador Foy D. Kohler briefed Khrushchev on the pending blockade and Kennedy's speech to the nation. Ambassadors around the world gave notice to non-Eastern Bloc leaders. Before the speech, US delegations met with Canadian Prime Minister John Diefenbaker, British Prime Minister Harold Macmillan, West German Chancellor Konrad Adenauer, French President Charles de Gaulle
