Not what I expected the four words to be based on reading the thread title alone. I thought it was going to be related to "Hitler did nothing wrong."
That is untrue. Hitler did not fully answer the jewish question.
There is doing something wrong and there is doing something poorly, incompletely or ineffectively. I agree that the matter of jews was not addressed in the manner that was required at that time and which is still required to this day.
Sadly, as aware as he was, with as much insight into the jew as he had, and with as much as he despised them, he still underestimated the evil of the jew.
Fair enough, I can get on board with that answer.
