[Ulenspiegel]

Heck using that argument Germany could stand up in 2014 and say "excuse me because that stupid Hitler made a mistake in 1939 we want the western portion of Poland back and the western portion of the Czech Republic back because we did not have a chance to correct that stupid Hitler
back in 1939"---so now we Germany also want our own "redo" of history because we Germany did not have a chance to call Hitler stupid back then and stop him.

Short version: For Germany it is much much better to have cordial relations with Poland and the Czeck Republic than to reclaim territory, in which no meaningful numbers of Germans live anymore and where BTW Germans as EU citizens could live and work if they like. What is your point?
