7/10 Nazi deaths were on the eastern front. Nobody said the USSR won the war itself, but they absolutely did contribute the most to the war effort. They were invaded by the largest land army in history and lost entire swathes of the country before eventually pushing the invaders out and liberating Majdanek and Auschwitz. US could have had a similar impact but we only got involved after Pearl Harbor. By then the writing was already on the wall for the Third Reich.
