I've been going through a number of Civil War alternate history TL's recently or just different scenarios, and it always seems that despite the massive butterflies of another nation on the North American continent, the balance of power in Europe never changes at all.
Of course TL-191 is the biggest and most well known offender, but I see other short stories, little novels, TL's here on the site and all in all Europe seems to stay just the same. France loses the Franco-Prussian war, England and the US remain allies (not so far-fetched but hey) the Great War always happens as a scripted, and Mexico still remains a poorly run, led, and backwards country.
My personel pet-peeve about Confederate Victory PODs is that nothing in the world and especially Europe seems to change at all. Canada is going to become a stronger nation for sure as the British recognize it, the Carribean is going to turn into a potential ships graveyard, and the alliance system in Europe is sure to be shaken up!
So what does the board think on this issue? Any ideas how Europe would change? Any TLs with those changes you could reccomend?
