Something I have noticed about history and regimes… When a regime’s ideology overrides facts; they’re screwed. You can see this all through history, but since this is WW2… The axis were ideologues and fanatics about their ideals. So much so, they were unable to deal with facts that flew in the face of the pre-existing ideology. They became victims of their own “confirmation bias”, and it hurt them badly. When your enemy ignores facts they don’t like, that’s a very nice “feature” to have in your enemy. Everyone does this a little bit, but the Axis did it a LOT. As an example, the US continued to believe the Japanese to be inferior people who would just be quickly swept aside. But after a few severely bloodied noses from “rolling in full retard”, we stopped repeating such nonsense and got about the business of fighting the war smart. Meanwhile the Japanese rhetoric said the US soldier and citizen just wasn’t as “tough” as their Japanese counterpart. The Japanese, right up to the end, kept believing they could shock the US into giving up. They kept thinking the US would see the Japanese as just too dedicated to their cause, and that would be the ultimate deterrent… While the US “mostly” adapted their views to match reality (not always though), the Japanese leadership never really did. And of course, you can say the same for Germany and Italy. The Nazi leadership consistently ignored the warnings of the Wehrmacht and as such never had a very realistic overall view of how the war as really going until it was way too late.
