So, what you're saying is it was perfectly ok for Stalin to be involved and handing German land over to Poles, but not ok when he carved up Poland with Ribbentropp? Hmmm... Explain to me how this is correct? Perhaps my ex-wife's family should go back to Allenstein and reclaim their property? They didn't support the Nazis, but the Polish communists repressed them and kicked them out. You willing to give them back their homeland?
You're kidding right?
Eastern Germany was given to Poland as a war recompense. You are being deliberately obtuse. You pretend not to see very simple distinctions. Chechnya was CONQUERED. It is a conquered land. Eastern Germany is not.
As for Stalin: it was not OK when he carved up Poland with Hitler, it was not OK when he drove 1,5mln Germans out of their homes. It was very, very NOT OK that there was a World War II.
