Doubt so. Hitler might have been a terrible man, but the fact that he had an outstanding leadership abilities is undeniable. He was a great strategist, but when every step you take can mean life or death for thousands, not even someone as smart as him could keep it going for long. If you wanted to give him a history lesson to help him out, talk Napoleon.
He too attempted invading Russia and he too was brought down by General Winter. Telling him how to fight the US is pretty useless when its only one of the countries he's attempting to push back to prevent Nazi Germany's eventual downfall.
