Start of Cold War

The Second World War has ended and people around Europe are very happy and relieved that the Axis have lost the war. However, it isn't long before another longer-term, but less deadly war is approaching rapidly, called the Cold War. After the defeat of Nazi Germany, the big two superpower countries left in postwar were the U.S.S.R. and the U.S., who were quick to become enemies. From history of both sides, they didn't have much of a great relationship and now that Nazi Germany was gone, and they were the two major powers left, they begin the long lasting tensions on nuclear aggression. Stalin in postwar had his army in the Cordon Sanitaire countries and he was going to "protect" these countries he claimed. In reality, he became hostile to any country he controlled that wasn't becoming communist. This later on caused people to move out of East Germany or East Berlin, were this became problematic to both West and East Germany and Berlin, the Berlin Wall was made to block both sides off so they wouldn't escape. The U.S. has a great economy going in post war and also they wanted to help out the Europeans countries in the West of Germany (expect Spain) to maintain their economy and stand against the U.S.S.R.. This became known as the Marshall Plan. It is also known from the bombing of Hiroshima and Nagasaki that the U.S. had an atomic bomb, and they try to intimidate the U.S.S.R. with it. However, when the Russians receive their first atomic bomb that works, it becomes the beginning of the arms race, or mass production of warheads between   U.S. and U.S.S.R..
