re: At full strength who was more powerful in ww2 Germany or US?

The Nazi philosophy was predicated on subjugating and colonizing the East. It was a core principle. Everything else was setting the stage for that. Poland, the war in the west, all of it was in preparation for invading the USSR. Godless Jewish Bolshevism had to be annihilated and the eastern lands farmed by Aryan settlers. That was National Socialism in a nutshell. There was always going to be a strike on Russia. There had to be.
