Then you don’t know much about Europe. How do you think the inhabitants of that area got there in the first place, you miss the point all together and yes they did get away with it, just to make it clear the inhabitants of Królewiec that is.
Evidently rather more than you, since I can see exactly how Russia would respond to mass deportations of their inhabitants. Interesting how your theory that people who "got to an area" can be moved out again by force relates to the situation of those Poles living in former German territories.
Do they ? I wonder, maybe theoretically they can, or maybe in your fairy story, in my fairy story mostly they are shuffled about without chance to exercise their rights .
I don't remember that happening within the EU in my lifetime. Do you often propose ethnic cleansing?
So, what time would you set to be relevant today?
None. Historical borders (like the Nineeenth Century borders between Russia, Germany and Austria) are not a basis for borders todayl, whatever you may think.
No, my argument is that Kalinigrand should belong to Poland because it is part of Prusy, country which have had many ties with Poland, and larger part of which belongs to Poland already.
Prussia no longer exists, its citizens are dispersed and its territory is divided. What was or wasn't in a country that doesn't exist and is spread across several nation states with no real movement to revive it is not the basis for Poland or anyone else to annex another country's sovereign territory.
