I disagree with the fact that when the US entered germnay was doomed. If Russia could have beedn captured, Germany could have rivaled the power of the US, and it is questionable whether the US could have sustained a naval war on two fronts. Additionally, they would have developed the A-bomb first. So i think Russia is the true key question. And i believe that had Hitler not acted as he had in Stalingrad there would have been a good chance that they would have succeded. I believe the answers then is yes, Hitler would have won, or at least have conlcuded some kind of peace maybe? I haven't studied any theoretical figures on this so it is really just idle and uniformed specualation
