The Soviet Union invaded those countries with its massive army. Just to give you an idea about the scope of the Soviet Army, the USSR lost 8.7 million soldiers during the war and still managed to conquer half of Europe.

The difference was that after World War II, the Western Allies withdrew a large portion of their armies and allowed the countries of Western Europe to determine their own governments.
