As a jew, I'm very happy that Hitler got the attention and special treatement by history that he did. However, objectively speaking there is constantly horrible things going on. Whether it be what you speak of, or Mao and is deeds, or the japanese experimenting on their own people in horrible ways, or the african wars (any of them) or the middle eastern fighting, or the irish civil wars......the problem is lots of those countries are the ones who write the history books and see no reason to include a lot of the horrible things they did.
