Not really, Speer was far more capable than Todt. And if all went fine, then no air raids over Germany, no more fighters nor FLAK needed...

Yes, the fuel is still being a tremendous problem. But it was only a problem after "Barbarossa". But think that all the German reserves could supply the new "Barbarossa", the entirely mechanised one. I think this was possible. What was not possible was to supply further operations, even smaller than "Barbarossa"
