""Missile crews were placed on maximum alert," Robert F. Kennedy wrote. "Troops were moved into Florida and the southeastern part of the United States. ... The Navy deployed 180 ships into the Caribbean. ... The B-52 bomber force was ordered into the air fully loaded with atomic weapons." But the idea of a surprise US attack on Cuba didn't sit well with some of the President's advisers, including his brother. "... a surprise attack would erode if not destroy the moral position of the United States throughout the world," Robert F. Kennedy wrote in his book."
