You should not overvalue your “asskicking”. It was the Russians that kicked our ass in WWII while the US played a “important underpart”. Old soldiers in Germany used to say “Kamerad von der Westfront”, if they wanted to express that someone was a harmless unexperienced freeloader. Why? Because on the western Front it was easy living compared to the blood and snow of the eastern front. More than your millitary was your once existing idustry a problem for Germany 1939-1945.
If the USA hadn’t provided massive amounts of materials to Russia during the war all of the USSR would be a slave labor camp run by the Gestapo.
The problem with Europeans is the gap in their history lessons called WW11.
If you read enough you would understand, but you live on a continent being flooded at this very moment with Islamic radicals.
