What tools did the us and the soviet union use to accomplishes their power goals in europe

At the end of WWII, the United States, Britain and the Soviet Union had met in Yalta in 1945 to decide how to reorganize the Europe and Germany. France was excluded and some of the agreements were respected and others were not. The US used the Marshall Plan to inject billions of dollars into the economies of Western Europe and Greece and ensure an access to American corporations and products. Then they formed NATO in 1949 which still exists and has been expanded to several new countries since the end of the Cold War. The Soviet Union on the other hand provided logistics and some financial support for the reconstruction of Eastern European countries and occupied them militarily, making sure that Stalinist Communist regimes were "democratically elected" in each of these countries. In 1955 they Created the Warsaw Pact which antagonized NATO until its dissolution in 1991.
