I've always found it pretty interesting - and funny as well - to see how AH writers are fond of imagining alternate timelines in which France would have splitted sooner or later - or never existed at all. This must be the result of long and bloody centuries of war and nationalistic rivalities in Europe, of course. But it seems to me a strong trend that, whereas most AH timelines show some huge and strong alternate German Empires, the hypothesis of a greater France, settled or not by Napoleonic wars, is not so popular nowadays ; and that on the contrary, most timelines seem to show with some kind of sadist satisfaction how this proud and famously chauvinist little country should have been dismantled. Well, why not ? But in this case, although I really like the map for esthetic reasons, I don't think the idea is so realistic. By 1900 France was already strongly unified, both for good (free education for all and creation of a real middle classe with hope for fast increasing of their level of life) and bad reasons (anti-German hate did make people of every region agree together after the Prussian war ; greedy colonialism in Africa and SE Asia was an important part of unpleasant French nationalistic pride, too). I'm not sure that a country who had insisted so much in building a common national culture during the last century would be so easily defeated, if not on the battlefields, at least in the minds - and especially against the German enemy... Think about what happened in OTL 1944 when De Gaulle managed to put himself amongst the WWII winners, against all expectations of the other Allies. Actually, French chauvinism is a strange thing, like a blend of genuine childish pride and self-irony. They must be beaten and look down on themselves first, to find then the reasons to fight back and win... oh, by the way, I'm French, in case you didn't notice. And sorry for my bad English.
I understand what you mean. However, some parts of France have greater chances of being wooed away from the main bulk of France then others; Brittany is a fine example, with some foreign support after a war as devastating as this is shown to be places like Provence and a revived and possibly bilingual Burgundy (probably tied into the German Reich moreso than other French successor states) could exist.
About Provence and Burgundy : well, this could have been, since they were part of other realms for a long time in the Middle Age (mainly the Holy Empire), and provided there would have been, during the XIXth century, a stronger cultural, intellectual and political movement towards Middle Age nostalgy (for instance if the romantics poets and writers had prefered to celebrate the ancient lords of Provence and Burgundy rather than supporting the Restauration of the French kings). Britanny, for the same reasons, could have resisted better the French jacobinism. Actually, the least realistic independent country on this map would be Limousin. This charming country of fields and forests would never have a chance to survive independently in a modern world. No big city, no access to the sea, no great roads or railways, no industry... well, you see what I mean.
I was agreeing with you, for the most part. Limousin struck me as odd, but a dysfunctional and useless French state such as that which couldn't act like a real country at all and would fall into poverty would be good for the Germans.
Actually the whole chaos would be good for the Germans. But this Limousin case could have some contrary effects... getting so far in humiliation might create some resistance and revenge feelings in the population. Even the Nazis didn't try to dismantle France like that, they only wanted to neutralize it and take profit on its natural resource.
