The united states hotly protested stalin's actions in poland, east germany, and the rest of eastern europe as a violation of the "one world" principle of the atlantic charter and a departure from the agreements reached at yalta and potsdam. aside from pushing for creation of the united nations, did american policy actually abide by its own principles, or was it just as much based on national self-interest as the soviet union's?

The correct answer for the question that is being presented above is this one: "Basically, Stalin himself is not part or not one of the signatories to the Atlantic Charter. At that time is the foundation document for NATO, which is an anti-Soviet alliance. USSR occupied many nations for the reason of protection of the borders and creation of buffer zone. For Germany, it is an assurance that Russia won't be able to invade Russia."

The United States were just as much based on national self-interest as was the Soviet Union. The thing with the United states was that they were seen as the good guys because they were democratic and capitalist, while the Soviet Union was seen as the bd guys because they were communist and a socialist state. 

Depends on your opinion but i agree
