In this case it’s also complicated by the lead up to the Cold War: I’m sure plenty of Germans resented that but even the ones who would consider violence knew that there was no likelihood of being able to win a military confrontation with the USSR. Attacking an Allied military occupation in Germany would not only have had no direct effect, it might have made things worse if that lead the American army to withdraw and leave the troublemakers to the tender mercies of the Red Army.
Again, my point was that while those countries didn’t have it great, they had peace after brutal wartime conditions and the prospect of rebuilding. Yes, having to flee would be unpleasant but they ended up in another part of their country where they were unquestionably welcome, spoke the language, and were able to participate in the government (which certainly hadn’t been the case for the previous decade for anyone who wasn’t a committed Nazi), and then the victors were rather generous in helping them rebuild.
