A large chunk of our western innovations are rooted in "1936" german research. US space program? From Mr Von Braun who was allowed on US land through operation paperclip. Axial jet engine?From Junkers Motoren engine propelling the Me 262. Modern submarines? From u-boats type XXI. Assault rifle? MP43. Highways, synthetic fuel, a lot of modern chemistry... So no, US did not come with most of the last 100s years innovations.
My family comes from a village in Belgium where the 12th panzerdivision SS committed mass murder, I therefore don't glorify these people, thank you. But you have to recognize what your modern comfort has to do with these people, and lower your morale standards accordingly. I'll help you: we are bad persons with low standards and a high, unjustified, self esteem.
