Superpower: the USA

For my superpower, I choose the USA over the USSR. The two countries were almost equal in army number, nuclear weapon number, power, etc. In almost every subject, we were basically equal to the USSR. Therefore, the Cold War ended in a giant tie between the USA and the USSR. However, the USA played a huge role in the coming down of the Berlin Wall. That one fact, to my opinion, is enough for me to believe that, if I had to choose a superpower that I thought won the Cold War, I chose the USA.
