I watch too much Military Channel and always wonder this. What if Hitler hadn't killed/persecuted Jews? IIRC, some of the most important scientists involved in the atom bomb defected from Germany. Imagine how quickly Britain would have surrendered if Hitler had the a-bomb. Beyond that, one of his main problems towards the end of the war was the lack of able bodied soldiers. 5 million more soldiers and factory workers surely would have helped his cause. Then finally, how would history have regarded him without the slaughtering of the Jews?
