germans and ethnic prussians maybe an independant state similar to austria. but not poles
Who the hell are "ethnic Prussians"? The Old Prussian language got extint in the 1600s and was replaced by the German dialects "Low and High Prussian" and all of them - decendants of "Old Prussians", decendants of German and Dutch/Flemish immigrants, Germanized Slavs, Polish speaking Mazurians and the remainder of Lithuanian speaking "Preußisch Litthauer" - got kicked out of their country or got killed in 1945.
It's not that I like that! I am not a friend of ethnic cleansing, and as a German patriot I don't take masochistic pleasure from the fact that so much territory that was German speaking for centuries is lost. But if you look what happened in that area during WWII one has to admit it was the logic ending of Germany's attempt to create a Greater German Empire on the cost of all of its neighbours.
If you really are an Englishman, which I doubt because your English reads like you never spoke to a native speaker before, I appreciate your feelings for our countrymen that lived East of Oder-Neisse before 1945. They had to pay the price for Nazi Germany's crimes which is sad and unfair, but most of them are dead now. And most of their decendants adopted the local culture and styles of their new homes, therefore they are no longer existent.
If a decendant of a German Silesian, Pomeranian or Prussian should feel homesick he or she can move to Poland. I really mean it! Many people still haven't understood that the border is open now. All he/she needs to do is looking for a home and a job, learning Polish probably would help, and then he can move to Gdansk or Wroclaw.
Or do you honestly mean that the Poles that live in the former German territories for over 67 years now would leave their homes in order to move the Kresy territories? This is so far from reality that I don't want to get into that discussion.
