Did the policy of massive retaliation allow the use of nuclear weapons?

Think about it this way; you're President of the USA, and you've hear of the mutally assured destruction. If you want to destroy your country along with another one, the use your weapons against Another Country. That is the idea of mutually assured destruction. There has not been one bomb dropped onto any other country since 1945; Hiroshima and Nagasaki. Tests have been carried out many times since then, especially during the Cold War. But there has been no nuclear explosions know to the public since then.
