There’s a good case to be made that Germany would have lost the war even without the Americans entering. The defeat at the battle of Moscow was basically the end of German offensive capability; they suffered a disastrous shortage of resources.
If the US invasion had not taken place Germany would likely still have lost, and the Soviet Union would have occupied a large chunk of Europe.
Germany would basically be all but guaranteed to lose against the Soviets and the English alone. It might have become a war of attrition sort of deal, but all was said and done after Stalingrad
