An unintended outcome of the three conferences held by the Big Three at the end of WWII was that  Eastern Europe was annexed by the Soviet Union.

After so many gatherings at the end of World War II, the Soviet Union decided to annexed some Eastern European countries in order to spread Communist in these nations and use them as a buffer in the case of a probable invasion. We are talking about countries such as Poland, East Germany, Hungary, Albany, Romania, and Czechoslovakia. This represented the period called the Cold War years in which the United States and the Soviet Union lived constant moments of conflicts and tensions because they were competing in the arms race and later, in the space race.
