Where was this picture taken and why is it important to world history?

This is a rare photo of the meeting in the Situation Room in the White House of JFK and LBJ during the "blink of an eye" nuclear confrontation of the USA, and the USSR.

The Cuban Missile Crisis of October 1962 brought the world close to a nuclear confrontation between the United States and the Soviet Union. The political positions adopted by both sides nearly prevented a resolution, but at the last moment, a compromise was found and nuclear war averted.

Putting ballistic missiles equipped with nuclear weapons into Cuba salved the insecurities of two men. Although John F. Kennedy had claimed that the U.S. lagged behind the Soviet Union in nuclear capabilities when he campaigned for the presidency, Soviet Premier the summer of 1962, Khrushchev also was certain that the Americans knew the same thing. Soviet missiles could reach Europe, but American missiles located in Turkey could strike almost anywhere in the Soviet Union. Khrushchev feared that the imbalance would tempt the U.S. to launch a first strike.

Russia blinked, and the USA won. Khrushchev was later deposed for this "blink".
