NATO

The Cold War would be described by the United States as a "good versus evil" conflict. The Cold War was a struggle between two superpowers staring each other down. Although the Cold War for other countries caught in the middle of these two giants was anything but cold. The origins of the Cold War come from the problems of what to do with the defeated countries. There were also actions taken by the U.S. that were directed at the allies, such as not renewing loans, that were seen as being aggressive by the Soviets. The Truman Doctrine of 1947 was a call for countries to resist communist aggression. The soviet Union also seeking a way to not have to deal with the Eastern European countries that were against them in the war. The Eastern European countries became a buffer zone for any possible future attacks against the Soviets. Soviets Russia set up Soviet friendly governments in many Eastern European countries.
A moment of cold aggression happened during the Berlin Crisis of 1948. The Russian blockaded aid coming into Berlin after what the allies violated the Potsdam agreement by combing their Berlin zones. After the aggressive blockade by the Soviets, the western European allies formed the North Atlantic Treaty Organization (NATO). The initial strengh in NATO was the fact that the United States was its military muscle. After much debate from the French, Germany entered NATO in 1955. They had to renounce long range bombers, missiles, and atomic weapons. The Soviets saw this as continuing aggression from the western powers. In response they created the Warsaw pact, which mirrored the NATO, but made up of pro-Soviet eastern European countries.
The Cold War continued for decades more, with the U.S. and Russians fighting battles with other countries as their pawns. The U.S. with its anti-communist rhetoric and the Soviets who seems to to honor aggressive tactics. The Cold War may be argued to still be continued with Russia seeming to be taking steps backwards and American conservatism rising.
