Given that some people on this board are of the opinion that the German defeat in the Second World War was solely Hitler's fault, ...
First of all the main false assumption is that Hitler was the only one who made any decisions for the Axis powers. It is true that he became more powerfull throughout the war but he wasn´t the only one to make decisions.
But on the other hand Hitler indeed made several decisions which influenced the course of the war greatly.
He was the one who stopped Operation Sealion and didn´t even think about a seaborne invasion.
But the turning point was Operation Barbarossa, of course.
German logistics were a major problem.
Before starting the invasion of the Soviet Union Hitler consulted several fortune tellers, astrologists and others.:crazyeyes He based his decision on their predictions of a fair winter in 1941. The German army then invaded Soviet soil without appropriate winter equipment, despite the protest of the generals. There was more than enough equipment in storage.
So in a sense it indeed was a major logistical proplem.
His second major error in this operation was sending Army Group Center to assist Army Group South in taking Kiev. AGC could easily have reached Moscow before the winter. At this time there was almost no defense there, the first Siberian reinforcement arrived only in late December.

But again! Hitler wasn´t a one-man government and military leader. Many of his colleagues in government and military shared his views or were afraid to disagree.
Without good german logistics the Blitzkrieg wouldn´t have been possible. That´s why nobody could stop them in the beginning.
But the longer the war lasted the greater the resource problems became, as mentioned by kobayashi.
The german African Corps was the first to 'feel' this lack of resources. Due to the naval superiority of the English in the Mediterranean, only few shipments could be made from Italy and an Army couldn´t/can´t be supported only with air transports.
At the Soviet front the problem was even greater because it stretched over several thousand kilometers. And the Soviet were destroying every infrastructure on their retreat.
The most well known example of lack of recources is probably the Ardenne counteroffensive in 1944. The german King Tiger and Panther tanks were far superior in firepower and armor. But after several days of advancing the tanks ran out of fuel and the now moveless tanks were a great target practice for the Allies.
