Riiight. The US and UK defeated Nazi Germany all by themselves. The Soviet war machine drawing closer and closer to Berlin had NOTHING to do with it. If not for the invasion of Normandy, the Red Army would have NEVER gotten to Berlin.
The Germans most CERTAINLY weren't screwed after Stalingrad.
Pull your head out of your ass. If the US hadn't liberated France, France would have liberated itself when the Russians defeated Germany. Don't try to argue that the Soviets wouldn't have been able to take down the Nazis. After Stalingrad the war on the Russian Front became increasingly one-sided.
