Jews were put into internment camps because of the rampant concentrated Bolshevist organizational and terrorist activity, not for just being Jewish. It was the actions of the Jews that led to their internment, not merely their existence.
The starvation was a result of the Germans losing a Total War. The German people were existing on 800 calories a day at the end of the war.
The Jewish Bolsheviks who took over the Soviet Union (and were funding Bolshevik activity amongst their Jewish brethern in Germany) spread starvation, misery and war across the globe for nearly a century.
