Leaping forward to 1940, a French controled enclave colony of Quebec or similar portion of Canada has interesting implications for US entry into WWII.
Lets assume the Brits dont want a French & Catholic population & are satisfied with control of the Ohio, western Great lakes, and maritime provences. The French get to retain their bit around Toronto - Montreal. That survives the Napoleonic wars, given back to the Bourbon throne after 1814.
I know this is an interesting topic, but in fact, this thread died in 2005. That's more than seven years ago. Hence we call this necromancy or reviving old threads.
