You apparently have no idea of the amount of German civilians the Allies and Soviets knowingly raped and killed. It was an absolute slaughter.

They overran and leveled entire cities. Dresden was only one. Hiroshima only got the bomb, and not Berchtesgaden, because the Germans surrendered before the bomb was done being built.

And the original post-war game plan was the Morgenthau Plan, not the Marshall Plan.
