How was communism imposed in the East and how did the Soviet Union plan to help those countries to achieve socialism?

Topic: The second half of the twentieth century in Europe was dominated by the Cold War, when Europe was divided politically and ideologically into an East and a West. How was communism imposed in the East and how did the Soviet Union plan to help those countries to achieve socialism?
