I mean, the USA was pro-Nazi until Pearl Harbor, and even then it took a propaganda campaign by the government to convince the American public to oppose Hitler.

Those Nazis were, by the way, inspired by the USA. Eugenics programs in North Carolina inspired later eugenics programs in Hitler’s Germany. Jim Crow was seen as a textbook example of how to use the legal system to enforce racial dominance, and was named pretty directly by Hitler as an inspiration.
