The Cuban Missile Crisis at 50

CAMBRIDGE – This month marks the 50th anniversary of the Cuban missile crisis – those 13 days in October 1962 that were probably the closest the world has come to a major nuclear war. President John F. Kennedy had publicly warned the Soviet Union not to introduce offensive missiles into Cuba. But Soviet leader Nikita Khrushchev decided to cross Kennedy’s red line surreptitiously and confront the Americans with a fait accompli. When an American surveillance plane discovered the missiles, the crisis erupted.

Some of Kennedy’s advisers urged an air strike and invasion to destroy the missiles. Kennedy mobilized troops, but also bought time by announcing a naval blockade of Cuba. The crisis subsided when Soviet ships carrying additional missiles turned back, and Khrushchev agreed to remove the existing missiles from the island. As then US Secretary of State Dean Rusk put it: “We were eyeball to eyeball, and I think the other fellow just blinked.”

At first glance, this was a rational and predictable outcome. The United States had a 17-to-1 advantage in nuclear weaponry. The Soviets were simply outgunned.

And yet the US did not preemptively attack Soviet missile sites, which were relatively vulnerable, because the risk that even one or two of the Soviet missiles would be fired at an American city was enough to deter a first strike. In addition, both Kennedy and Khrushchev feared that rational strategies and careful calculation might spin out of control. Khrushchev offered a vivid metaphor in one of his letters to Kennedy: “We and you ought not now to pull on the ends of the rope in which you have tied the knot of war.”
