Spreading American values and culture has always been the goal of the nation since the very beginning of World War I. This interest in spreading democracy and later on encouraging a capatilistic world, helped to fuel both WWII and the Cold War. In this attempt to make the world more safe for democracy to exist, the U.S. started its own battle with communism. Additional efforts extended a helping hand to European nations which desperately needed the help after falling apart post Cold War. Examples supporting this are the Truman Doctrine and the Marshall Plan. This informally changed American foregin policy in regrard to the U.S.S.R. No longer was the U.S. trying to build relations with the nation or suggest friendship (detente), but rather preferred a policy of containment of the U.S.S.R’s expansion.
How did the Cold War start? Who started it and for what reason it was fought are all questions which are important, but can all pretty much be answered by one word: containment. The fear of the spread of communism as the U.S.S.R expanded posed a direct threat to the U.S. In accordance with American ideals and capitalism, a world with safe choice of communism would possibly even create an uproar in the U.S. as well. In order to prevent this from happening, American foreign policy in Europe changed quickly.
