America's Response to the Soviet Behavior in Eastern Europe From 1945 to 1956 after World War II the United States had little involvement in European issues. However, following the events in other parts of Europe in March 1947, President Truman changed his foreign policy to "containment". Truman says these things in the doctrine called "torumanism". In this doctrine he promised to "support the conquest of free people and external pressure by resisting the attempt of armed minorities".
After the war from 1945 to 1949, the Soviet Union adopted a "Soviet" policy and began expanding to Eastern Europe by establishing a friendly satellite country in Moscow. The Soviet Union believed that this was a purely defensive behavior, but the West believed that this was evidence of Russian expansionism. Therefore, the entry of the Soviet Union into Eastern Europe is an important reason for the conflict between the West and Russia. One of the dynamics behind Stalin's expansionism policy towards Europe is the expansion of the overseas economy. Based on this, we believe that one of the main reasons that Stalin established the satellite state in Eastern Europe is to ensure that he has sufficient market to trade with it and the economies of other countries To ensure the influence of the Soviet Union. But like the Soviet Union seeking safety, there are other more important elements that determine its policy towards Europe.
At the end of the European War in May 1945, the Soviet Union occupied much of Eastern Europe, including the Baltic States, Poland, Czechoslovakia, Hungary and East Germany. "Big Three" including Roosevelt, Churchill, Stalin, recognized the fundamental conflict in their class. The confrontation of this ideology occurs between the Soviet Union that believes in a socialist one party state and the United States that is supported by the UK, and the UK is a free and democratic country where capitalism is growing fast. Stalin also noticed that the West opposes the long history of the Soviet Union. Throughout the military history, Russia was repeatedly invaded by Napoleon and the recent Hitler in the 19th century. Importantly, these and other intruders are mostly from Poland. So, as you will see later, Stalin is anxious to protect Poland, the main reason is to prevent future invasion. This is the main reason Russia dominates Eastern Europe.
