It is now 1944. Can you devise a feasible scenario in which Hitler may win or at least make the war a stalemate ? is it possible ?
This is for April 1944 but it gives a good approximation of what is going on.
Dig in with whatever land you have left and surrender all russia that you invaded, reconsolidate everything and propose a ceasefire. The german people would welcome it, and you could justify it to the allies by saying 'we've all killed enough, let's stop this and talk'. Give a few years of bullshit armistice talks to solidify/build up whatever land you ended up holding on to and end the war with some parts of africa, poland, and part of france ect. Cut your losses then use your industrial structure to become the economic powerhouse of europe 50 years early
That's a bit of a shit map, it entirely ignores all the Partisan territory behind the Eastern Front
