The Nazis had very impressive uniforms, they had very talented scientists under their wing (inspite of their bigotry alienating or killing Jewish/gay scientists), they ran their economy somewhat better than US Neoconservatives, and they militarily outperformed their Edwardian era logistics in Europe against strategically superior opponents for years, but apart from that they absolutely stank morally overall, and their genocidal brutality was a spectacular demonstration of sheer incompetence, rather than genuine strength.
Although I really think the Americans are wrong in exclusively depicting them as just 2D monsters or faceless goons.
I'm also convinced that many stupidly myopic Nazis had recent Jewish or Slavic ancestry anyway, given the historical background of Germany and Austria, with religious conversion and migration from Southern or Eastern Europe (this obviously goes both ways since William Shatner ironically looks more Germanic than Adolf Eichmann, a small and swarthy person you wouldn't look at twice in a shopping mall in Tel Aviv, Damascus or Beirut

).
I certainly think Japanese have been given a free pass unlike the Germans, with their savage racism against fellow East Asians to be also equally puzzling, inept and childish, even though I found the wartime anti-Japanses propaganda to be genuinely sickening.
