If the US hadn't entered, Hitler would have taken his time invading the USSR. The Nazi supply lines would not have been stretched, and more countries in Europe and Africa would have been conquered adding more fighters to the Nazi army. There would also be a pincer attack against the USSR involving the Japanese, and Italy would have likely added to its fighting force and moved up from the south of the USSR.

I'd love to have seen the poorly trained, armed, and supplied USSR army survive that. Stalin killed so many farmers that the USSR food supply would have run out long before Hitler's desired time to invade Stalingrad and other major cities. The Japanese attack on Pearl Harbor caused Hitler to believe he needed to hurry up, despite tactical advice from his military advisors that it would not be a good idea as it would do what it did -- stretch supply lines.
