who cares? there are just 2 outcomes, isolation or intervention, you dont need to model the senate for that...
that was a legit plan that was deemed to pacifistic. the problem with it is that Germany would have never used it. Its maybe a good idea in a scenario where Italy did something useful.
That overestimates the power of the SS and Hitlers ministers. the Wehrmacht would just take power and install the Kaiser.the Party minister would all be gone.
Well Africa would have been mostly german with some parts going to italy. the amount of germans in Africa would be very very low.
A giant landmass with good resources and massive amounts of free labor is just to good to not go there.
Centralised planned economy under Speer, Porsche and Von Braun would mean Mars colonies in the 70s.
also not much force needed in a mostly empty russia. no way the majority of Russians would survive 20 years of forced labor and extermination campaigns...
are you nuts? free resources, massive amounts of free labor and no jews stealing money would mean a massive boom for many decades. till ethnic germans reach a billion in numbers and an empire spanning most of europe and Asia.
