I'm sorry,[...]
(As you quote "New Caledonia" I assume you was answering me, my bad if it's not the case)
My point was about a governemental and diplomatic reaction, not the overhall french position on it : after all any state have to react on topics that couldn't be less let aside by popular opinion, isn't?
In this line of ideas, a quick recognition of Québec could have been unwise politically for reasons aforementioned.
In sum, French separatist movements pose no serious threat or thought to the French state; unlike Basque, Catalan and Scottish movements.
I disagree, while Breton movement is largely represented by a half-hearthed autonomism (while a breton deputé is the only regionalist representative in the assembly), Corsican and Basque regionalism/autonomism/independentism (all things considered) still represent respectivly 5 and 10 percent of votes.
For the "tought", I don't really get what you're meaning I'm afraid, but it seems (from polls, so to be used with an extreme caution) that "french" identity is or associated with local "one" (people identifying as much as french than [put your region name here], while local identity can be indeed stronger than french one in some case.
We don't really have an overhelming reject of regionalism/autonomism and even if independentism is far less a political force than in Spain or Scotland, it can admittedly be considered as a local matter.
