I mean, 'Nazis bad' was supposed to be the self-justifying narrative of modern civilization.
The story went: Yes, industrial society is built on colonial horrors, but remember we defeated the Nazis. That's our redemption story, it wipes the slate clean and opens the gates to a morally neutral future.
Now that's all being dumped, as the Nazi taboo is broken, because it turns out things like short-term profits and political gains were more important all along.
