Well, lets think about this a little.
As it is by the start of 1944 vast amounts of German production are thanks to various forms of forced slave labour.
I take it that is still going on in this rather silly fantasy.......if not then by whom how is that to be made up?
Yes, it was slave labour, but it worked very well, like it worked in my country for centuries and in many others. Speer provided better conditions for the "workers", and they would have better conditions if there was not a blockade and the Germans could feed them better. In fact, without the blockade, Fustanga Europe would produce much more, because the blockade prevented many critical raw materials needed for the industrial production (this don't even includes a Lend-Lease, because if yes, it would be even better). Even Italy would have appreciable industrial gains in this scenario. Again, I'm not even touching in the US and British participation, because they would bring something like a revival of the German armed forces as far as the joint effort is concerned, particularly the Luftwaffe in order to kick the Commies back to their lands.
