Let's remember that the historical name of the city is Königsberg. After the occupation the Soviets executed an ethnic purge of the locals and annexed the land.
(And Croatia would have to give up Rijeka to Italy. And the whole Alsace-Lorraine stuff would return. And I'm not even talking about Germans returning to Czechia or Romania.)
As fully agreed to by the Western powers via the Potsdam Agreement.
Let's all dance in remembrance of that, also.
Of course, this agreement has since been violated, notably by Russia.
What does Russia have to do with Kosovo?
They are both part of the history of human occupation at that geographic site, let's remember that.
Perhaps you'd be better served by asking them what point they sought to make.
