Yes, I think you are right to. Stability was indeed the basis for what authority the USSR and its allied regimes had. And compared to the disasters visited on them, that was indeed appealing. I have lost the quote, but I think it was Primo Levi who accounted for the authority of the Red Army in the disintegrating East Europe as simply a matter of their having the supply lines that could furnish the gasoline without which communities would starve for want of resources. And Paul Mattick described the victory of the SED in the East Berlin elections as much as a yearning for acceptance, and the restoration of order as anything else. von Paulus returned to duty as a traffic policeman in East Germany after the war (while von Braun, who shot missiles at my parents, joined the US space programme).
It is true too that it was the US and allied authorities who raised up the Iron Curtain, because they could not allow the effects Marshall Aid to be spread too thin, but needed to restrict their aid to west Europe, and let the east go under. Whatever fantasies Patton had about carrying on eastwards, the west needed the Soviet Union and its allies to hold East Europe together, because one thing was certain, the US army was in no position to.
