On October 22, 1962, President John F. Kennedy gave a televised address informing the American public that the Soviet Union had installed missiles in Cuba. Kennedy announced a US naval blockade around the island to prevent further delivery of such weapons, essentially declaring that any missile launched from Cuba against the Western Hemisphere would be considered an attack by the Soviet Union, and would prompt a full US retaliatory response. Kennedy demanded the removal of the missiles from Cuba and warned of serious consequences if the Soviets did not comply.
