Soviet Union vs the US from the 50s-80s (DUE IN 1 HOUR ESSAY)

 

In the 1950s, the Soviet Union was depicted in American popular culture as evil, and America as good; by the 1980s, much of the popular culture depicted the United States and the Soviet Union as morally equivalent to each other. Why do you think this change took place?

Your answer should consider the historical context of the Cold War in the 1950s and the change in historical circumstances by the 1980s, both in terms of American politics and the international situation.
