Changes

Although not considered as significant a U.S. foreign policy failure and embarrassment as the Bay of Pigs invasion, Operation Mongoose failed to achieve its most important goals. Meanwhile, throughout the spring and summer of 1962, U.S. intelligence reports indicated expanded arms shipments from the Soviet Union to Cuba. Amidst growing concern in Washington over whether the Soviet weapons being introduced into Cuba included ballistic missiles with nuclear warheads, in October 1962 the Kennedy administration suspended Operation Mongoose in the face of this far more serious threat—one that resulted in the most dangerous confrontation between the United States and the Soviet Union during the Cold War.
