Sure, Germany pays reparations, Poland gives back Pomerania and Silesia (which were part of the reparations) and Western Europe forms a new EU so we don't have to deal with Poles any longer. Deal?
Germany lost the war. That's just small price they should be paying for exterminating millions of people and destroying many countries. And these lands were Polish, and Czech way before there were Germans. That's why Prussia had a systematic depolonization going on in the 1800s on these lands. They wanted remove the inhabitants of these lands for a long time..
Are you still lacking lebensraum?
