America, Russia, and the origin of the Cold War The Cold War occurred when President Harry S. Truman of America released his torumanism. This doctrine points out that the United States supports "free states opposed to armed minorities and external pressure to conquer". This will eventually form the basis for the US to participate in the Cold War. The main idea of doctrine is to support the country by resisting communism. Truman believes that when a country falls into communism it leads to a "domino effect" that causes many other countries in the region to fall into communism.
The two information sources chosen for evaluation are Walter LaFeber of the United States, Russia and the Cold War of 1945-1996, and John Lewis Gaddis "We Know Now: Reconsidering the History of the Cold War". They are all second - hand materials, especially the latest on the recent Soviet and Chinese documents, we use the latest research on the Cold War. As an expert in the history of the Cold War they have been admitted by the public and colleagues for a long time and their work and information are almost exclusively used for all topics related to the subject. Both are representatives of the two main trends of the Cold War. LaFeber is always one of the clearest supporters of the revisionist approach and Gaddis is considered one of the best historians in the post revisionist view. The works of LaFeber and Gaddis are their latest works: LaFeber is the eighth edition, the first edition is 1967
The Cold War broke out for various reasons. First, the difference between Soviet Russia and the United States led to the Cold War. The United States can not tolerate Soviet communism ideology. Russia, on the other hand, can not accept the advantage of the United States against other European countries. Second, arms race between the two superpowers is another reason for the Cold War. After the Second World War, the Soviet Union strengthened the military power that threatens the Western countries. As a result, the United States began making atomic bombs, hydrogen bombs and other deadly weapons. Other European countries also participated in this competition. Therefore, the whole world was divided into two power groups and opened the way to the Cold War.
