Private American interests definitely bankrolled Hitler, and there was an ideological component to that. Hitler pointed favorably towards segregation in the US as a working model for how to be a historic tribal cheiftan. This is definitely conspiratorial conjecture on my part, but I think arming a world power against "international Jewish bankers" may have appealed to financiers who were competing with institutions like Rothschild, Rockefeller etc. To point specifically at American money, Chase were honorary SS - always thought the Chase bank logo had a funny, symmetrical style to it
wonder where Meatgrease puts his unemployment money. Ford himself had a legitimate personal impact on antisemitism in Germany, as an
author and not just as a guy doing car stuff.
Shit like eugenics was super widespread here for a long time. Some suprising names come into that history... I only learned recently that Margaret Sanger from the Birth Control League/PP was in full-on 8chan mode and probably got a bunch of people sterilized. Again there was a direct relationship between that culture here and what eventually happened in Europe.
I have a magazine from the 1930s which was printed in New Jersey, which has an article about the upcoming launch of the Hindenburg. It has a few beautiful photographs of the ship, complete with the GIGANTIC swastika nobody ever told me about in school. The article lavishes praise on Hitler, and his successes in revitalizing the German economy. The German-American bund is a pretty well-documented thing. Opinion was very divided but absolutely did not turn 100% anti-skub until 1942.
All that said, I think the true explanation for our hesitation in entering the war is just isolationism and a non-interventionist spirit. It's no different from the discussion about Ukraine today (minus the forever-war aspects I guess). Most Americans were genuinely naive about the holocaust until the 1970s; the world is full of atrocities, and most people simply dont incorporate them into their conception of history unless encouraged to through institutions or whatever. Bombing civilian targets was pretty widespread in WW2, and I dont know how I'd go about establishing any particular eagerness to nuke the Japanese for ETHNIC reasons as opposed to the fact that they were an axis military power who declared war on us.
Too much to get into here, but there's TONS of shit out there talking about how we handled reconstruction in Japan as respectfully as possible (much better than in France) which I don't think we would have done if the spirit was as you say.
I'll finally say this - we've had ~70 years of KGB-provoked anti-imperialist revisionist history pouring out of every academic institution in the country. In the same way we successfully undermined Soviet society, they hoped to undermine ours - and that situation produced every criticism of our civilization and its moral roots that you could ever hope to read.
Although I'm no expert I don't think I've ever heard anyone make your proposal. Not saying you couldn't be a pioneer.
Fun fact - the first issue of Captain America had a cover featuring Cap punching Hitler in the face, and winning the war. It was published 11 months before Pearl Harbor! The guys at Atlas (proto-Marvel) got in fights with the German-American Bund, which was a block or two away. Dont know how serious it was but they definitely yelled at each other on the street. Those guys were Jewish (as were many in the industry) which obviously supports the ZOG hypothesis. I am not joking, that is my true and honest final thought unironically. Thank.
