"Thus the role of the Soviet Union in Eastern Europe was contradictory from the beginning, yet it was also a roll imposed on the Soviet Union by Hitler’s invasion."

So Stalin was forced to occupy these countries under his totalitarian regime just like any other imperialist power?

Regardless, this is straying from the point I was making - in the United States, we enjoy a degree of freeom that has yet to be found in any communist nation.

When it comes to who's done more good for the world - neither - in any example brought forth governments are acting in self interest and that precludes in moral superiority. The U.S has Vietnam, The Phillipines, Nicaraugua and many more shameful acts - conversely, Communism's luminaries include Stalin, Mao, Pol Pot, Kim Il Sung - together these governments have killed untold millions.

If you want to improve the world it's government you should be going after - powerful government wreaks untold havoc.
