The greatest turning point in WWII was when Hitler decided to go to Russia. Adolf Hitler was a very smart and strategic man however his decision to march to Moscow during the winter was possibly his biggest mistake. At this time the German army had almost no resources and were suffering from the extreme conditions. As a result of the weather the army could not march as fast and conquer as much land as expected or needed to even have a chance of reaching and doing damage to Russia. What could of possibly changed the outcome of this march were two things. First Hitler could of sent his army earlier before the winter (if they had not had to bail out Italy) or they could of sent the army later after the winter. Secondly and the most likely to happen as a result of having to help out Italy would of been if they would have marched further south towards the oil fields. If Hitler made the decision to march south he would of been able to take out the Red Army and he would of been able to gather the needed resources to make the trek to Moscow.
