This is either ignorant or dishonest. Just because the US wasn't insanely profligate with lives, doesn't mean they didn't make a huge contribution to defeating Germany. Multiple German armies were defeated by the Western allies in Africa, Italy, France, the low countries and subsequently Germany. Germany's war production was crippled by USAAF and RAF bombing, and its transport was almost totally destroyed. Perhaps most importantly, Germany's ability to fuel its vehicles was removed by the bombing campaign. Literally thousands of 88mm guns were kept in the Reich because of the bombing, and these would have been on the Eastern front shredding Russians otherwise. Without this contribution, the USSR could at best have reached a stalemate. Anyone who denies this has an agenda.
