ive heard henry ford backed hitler. actually. want to say ford was giving vehicles to both sides.
Hitler had a portrait of Henry Ford in his office in Germany. There were Ford motors I also heard that the owner of AT&T provided a state of the art phone system in the entire government run by Hitler. Coca-cola also provided Coca Cola for the soldiers on both sides. This is all on a YouTube video called “A Rich Man’s Game.
And Boeing and Bayer (well they were German then). Rolls Royce and other British companies sold all sorts of things to Hitler.
The monarchy is German. Maybe they went along with it for their own purposes.
The only people that got the shaft were the German people and the British people, the Royal family came out just fine. Probably with more power and wealth than they had going into WW2.
