I wonder when the Germans are going to ask for the 1/2 of East Prussia that Stalin took. The Russians still have it, complete with Koenigsburg, which the Russians renamed Kalingrad. The Russians moved Poland West about 200 klicks after WWII, taking the Eastern third of Poland and giving the Poles a slice of Germany in compensation. All the areas were ethinicaly mixed, but after WWII Poles were often moved out of land taken from Poland and practically all Germans were removed from within Poland's new borders. If the Germans get compensation from Poland then the Poles can ask for compensation from Russia and Belorussia and Lithuania. Slovakia, Roumania and Hungary can ask for compensation for their territory siezed by Stalin and, well you get the picture.
Folks in Europe need to acknowledge that every square inch of the place has been taken by force many times and that they are either going to live with their current borders or return to incessant tribal warfare.
