What do you think World War II would be like in world where Germany won WWI, assuming it sill happens?
Point of divergences: no USW, so USA remains neutral and France surrenders in 1917 or 1918. Russia still goes communist (although probably more contained than in OTl - no Ukraine).
I think Nazi-like regime is likely to come to power in France. Even if it does not, anyways France obviously would want revenge, and Britain probably too. Not sure if they will make alliance with Soviet Russia...
Like other posters in this thread, I'm sceptical there would be a WW II in a scenario where the Central Powers won in 1917 or 1918. The peace terms the French will get won't be a slap on the wrist, but more likely an alt-Versailles or something even worse: crippling war reparations, demilitarization of the border, a police force sized army, German naval bases on the Channel coast, annexation of the extremely important coal producing Brie-Longwy area and whatever colonies the Germans fancy and which the British will likely give to prevent a total occupation of France (and Belgium).
Even if some French version of Hitler rearms and the Germans let them for some reason, Germany outnumbers the French 3:2 and has a much larger economy with way more coal and steel. Moreover, in a 1917/1918 peace Russia won't be there as an ally. With WW I over and Brest-Litovsk hiving off Ukraine, Poland, the Baltics and Finland, Germany will then move to kill the Bolshevik revolution in its cradle and after that we're likely looking at a Warlord Russia which to Germany would be what China was to Japan in the interbellum.
Not saying it's impossible, but it's unlikely. Before making a move, France would need to find some very powerful allies: Britain (obviously) but also the United States, and the latter needs to be in from the start at a war footing to prevent France from falling. The French would understand this. An alternative to wow Germany into some kind of advantageous peace would be a French blitzkrieg, but I'm not sure they'd develop it. In the end, proxy wars are more likely IMHO.
