The Cold War is a constant political and military tension between the United States and the Soviet Union, which led to various views on the emergence of tension. Even today, even after the Soviet archive was announced in 1991, this problem has not been solved yet. The main point of disagreement is related to the role of ideology in the events from 1945 to 1949. For decades, it is strongly opposed ideology, capitalism and communism, or power and material benefits that superpowers are driving the fight for global hegemony.
The reasons for the Cold War have room for discussion. The ideology of capitalism and communism is different, so the Cold War is inevitable. However, we can not completely point out who is responsible for the Cold War. There are many factors that may lead to the Cold War. Many historians have different views on the cause of the Cold War. The orthodox view generally believes that the Soviet Union is responsible for the Cold War. It points out that the Soviet Union inevitably is an extensionist as they doubt the West. Therefore, Stalin decided to violate the agreement between Yalta and Potsdam, to occupy and dominate the Soviet Union of Eastern Europe, and "draw" the spread of Communism around the world.
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.
