As the title says.
FPotS, let's assume that WWI and B-L goes through, but Lenin manages to get killed, and the Reds collapse. The provisional Russian government manages to reform into a democratic, if not corrupt republic. However, the Nazis still manage to come to power in Germany once the Depression hits, albeit slightly weaker due to the lack of the 'Communist menace'.
How would WWII play out, with a White Russia? How would they fare against the Nazis if they invaded? If they win, what would post-war Europe and the rest of the world look like?
