The land that the Germans occupied was a property of Czech Crown and later the Czech people, they had their full right to get rid of Germans once they tried to betray their host nation.
My granddad was Bohemian ‘Sudeten’ German. Bohemia was known as the bridge of east and west Europe. It was always a religiously tolerant place where everyone was happy to live and trade together. The people lived in peace.. Until politics ruined everything
I wouldn't say "in peace" unless you mean the Slavs that inhabited the East of the Elbe rest in peace (like Polabians & Sorbs) then yeah. The Germans ruthlessly expanded beyond the Elbe and exploited the lands and people for a thousand years. Ended in 1945.
It’s October 2023 now and we are watching the horrific ethnic cleansing effort in the Middle East unfold in Gaza and Israel. Really is much the same issue….in the end we are all residents of the earth….nobody can truly lay claim to certain lands….and until we all accept that as a truth and learn to live together these horrors will continue. (My father was a 3 month old baby in Jan 1946 when he, his mother and grandmother were first sent to the camps and then deported from Olmutz to Bavaria. His mother never revealed who his father was….after much genealogical research I am coming to the very sad conclusion he was conceived in the most horrific of ways).
