One thing that always annoyed me about Turtledove's TL-191 series (apart from the fact that Sam Carsten sunburns easily, and zinc oxide cream does not help much, and Sam Carsten sunburns easily, and zinc oxide cream does not help much, and Sam Carsten sunburns easily, and zinc oxide cream does not help much, and Sam Carsten sunburns easily, and zinc oxide cream does not help much, ad infinitum) is the fact that he assumes that a victorious Confederacy that got there by British and French help produces almost no butterflies whatsoever.
Some examples: the Franco-Prussian War of 1870 and the Russo-Turkish War of 1878 both appear to be totally unchanged. The Hispano-Japanese War of 1898 in TL-191 is a blatantly direct analogue of the Spanish-American War in OTL despite the fact that 1) Cuba was taken by the CSA in the 1870s, presumably altering Spanish policy toward her remaining colonies, and 2) there is obviously no analogous trigger for the war. And then there's the Russo-Japanese War of 1905. This is, of course, all necessary so the Entente and Central Powers lineup in 1914 is implausibly exactly the same as OTL, fifty years after a POD.
So, as we all know better, what changes to the OTL pattern of late 19th century wars and alliances would result from the TL-191 POD?
(For those that don't know, this is essentially that Lee's Lost Orders aren't, he fights a successful campaign up into Pennsylvania, and Britain and France recognise the CSA and apparently provide a small amount of military intervention against the USA; then twenty years later in 1881 there is a more direct Anglo-French attack on the USA when the Americans declare war on the CSA over Confederate annexation of Chihuahua and Sonora).
