There is a saying "he who sows the wind will reap the whirlwind". Nazi started the World War II so in a way they are responsible for what happened later to many nations. And I'm not talking only about raping and killing but also for destruction of many cites, art pieces, and so on. Of course what nazi had started is no excuse for raping done by Allied troops.
285,000 raped women seems like a lot, so i'm not totally convinced it was so high number. The method that Dr Gebhardt used is highly implausible.
