The thing with Hitler is that there’s a template to learn from.
Hitler should have been dealt with a lot earlier than what he was. Hitler also governed a very different population and situation at the time. America isn’t where it is because it was held hostage by taxing war agreements and governed by oppressive outside influence…it’s a bunch of over indulgent and privileged arseholes being exploited.
The Germans didn’t know what was coming really. American do, and not only that they gave it a trial run.
The only similarities are the political ideology, not the countries themselves. Americans can still stop this if they want.
