Imagine if he was just a bit less extreme

Never starting a war on two fronts. (Mainly by attacking Poland). Instead building an anti-Communist coalition of European countries against the Soviet union. Perhaps satisfying anti Semitic attitudes in Germany at that time by passing some laws prohibiting Jewish involvement in politics and media, but never shoving them into concentration camps. He could have saved Europe from 50 years of communism. With his already existing achievements unifying Austria and getting Germany out of depression, he could have gone into the history books as a good guy.
