So the only crime the Nazis were guilty of was losing the war. Check.
So by your argument, anytime someone defeats a predatory or genocidal assailant, the victor is guilty of the same or worse atrocities as those that made the defense required, and not only that, after the war is over the genocidal assailant who started the whole thing is guilty only of losing the war?
You're a loon. And a fairly obvious troll. On a small scale, think of a guy who starts killing his neighbors, kills a few dozen of them, and he operates out of his home. His home is occupied by his wife who doesn't participate in the killing, but who provides support. His home is also occupied by his 2 children who he is training to continue his exercise in murder. He's a wiley bandit, and we know that tomorrow he's going to kill another 10 people so we have to stop him tonight, and the only way we are sure we can do it is to attack him while he's in his house, which will probably kill his wife and kids. What is the moral thing to do? Who is guilty of the inevitable tragic results? Does the killing of his whole family to stop his murderous rampage make "us" as bad as or worse than him?
And what do I think about some jerkwad armchair quarterback who a week later, discovers that oh yea if we'd done this one thing differently we could have stopped him without killing his whole family, and therefore the person who ordered the raid was guilty of an unnecessary crime? Nevermind that at the time any other known course of action would have resulted in 10 more dead people due to the indecision or inability to make a moral distinction between killing "innocents" who are supporting or shielding a mass murderer, and the victims (and future targets/victims) of the mass murderer? I'll back up the leader who is able to make that moral distinction almost any day over some loser armchair quarterback who thinks he's smarter than the people who were actually there having to make the tough choices.
The winner writes the history books but its pretty clear to me that trying to crucify the people who stopped hitler and who were desperate to find an alternative to an infantry invasion of Japan is despicable.
