@Eiswald The only two big mistakes Hitler made was trusting the non-White and imperialistic Japanese and not trying to at least placate the Americans, where many German descendants lived. if not ally with them or at least various states and American localities hostile to FDR's regime. He did not have a high view of us, which I think ended up making him underestimate American power and potential hostility, including after Pearl Harbor the damage America would do during the war, in terms of aiding the USSR and creating too many fronts for the Wehrmacht and SS
