How is that a new take? It's literally what I learned in high school and college history classes. WWII ended with the Soviet Union and the USA as victorious superpowers that feared each other's strength, to the point where the USA refused the Soviet's offer to help with Japan after V.E. day.

I have a degree in History, which is worth less than the paper it's printed on, but that's the broad explanation behind the beginning of the Cold War. I'm not downplaying the idealogical differences in culture, religion and political influences, but just simplifying it for a reddit comment in a creative writing subreddit.
