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
Brinkmanship War was the Cuban Missile Crisis (15.10.62 - 28.10.62), a 13-day conflict between the US, USSR and Cuba. The US and the USSR, each armed with nuclear weapons, both practiced brinkmanship during this conflict. The Cuban Missile Crisis was not only the closest the US and USSR came to an armed conflict during The Cold War, but also, to this day, the "closest the world has come to [a full-scale] nuclear war." The crisis was caused by the placement of Soviet nuclear weapons in Cuba, an island that was within the "Sphere of Influence" and launching distance of the US.
