As WW2 raged in the fall of 1944 Comrade Stalin issued a decree; All ethnic Germans would be expelled from East Prussia, Silesia, Memeland, Poland, Hungary and Sudentland (Czech). Over 17 million deported by the Red Army by Summer 1945. Other terrible crimes which included rape and murder.
Churchill, Roosevelt, Truman all endorsed his idea. This solved the German ethnic crisis which started WW2. Germany is now the most peaceful nation in the world. The west should expel all Muslims back to the Middle east and do a population exchange with Pakistan, Iraq we take their Christians. This would solve the Muslim crisis which has brought chaos and destruction. This would benefit all parties involved.
