Eisenhower gets MAD​
With nuclear weapons came unmentionable powers which granted a single human being the capability of destroying an entire nation with a single push of a button. However once both countries got control of nuclear weapons things became a little more interesting.
Because now they could destroy each other very quickly. And this is were Eisenhower gets MAD because if either he or the USSR fired nukes they would ultimately destroy everything or Mutually Assured Destruction . This basically guaranteed that if one country fired a nuke they were guaranteed to have nukes raining back down upon them. This is the reason that some countries want to be nuclear capable as they are deterring other countries from firing by having their own. And to keep these nuclear weapons as far from America as possible or even in other countries Eisenhower had the CIA push coups in Iran and Guatemala to prevent communism. And would also start NASA to compete in the space race so we could get to the moon first
