Well things continue with Russia vs the West. i still don't feel much drama as Russia's defeat still seems foregone, even if the shape is up in the air. I trust though you have something in store, even if this war ends up as the set up to said thing. I wonder if the Tian Dynasty will try to get in on the action.
With Japan likely to lose this war the Shogun has pushed in spite of the Emperor I wonder if defeat will end the dyarchy with the Emperor taking full power. interesting divergence with the Daimyo's becoming hereditary governors and the samurai being retained and updated. I wonder if the samurai will be able to adapt into something that be effective in this era, even if only for awhile?
Good that Japan's military commander at least is smart enough to know he's out of his depth. With the navy seeming to be toothpicks in the making it seems to set up for an invasion of Japan proper.
I see local democracy survives in the UAU, what about the state governments?
So the FAPM is based on the alliance between grassroots antiJackson politics and the DUAY? Interesting.
WILD THEORY TIME:
For Jackson's fate as you imply it will be interesting i have a new theory. Namely Jackson escapes the fall of his regime and flees abroad vowing to return. While he never does dying abroad he is not just idle. my current guess is he turns up with followers in Paraguay of all places, as an advisor and recruiting other exiles for a fellow republican dictator's cause, all the wile still styling himself as the legitimate American President.
I pick Paraguay because Jackson would likely not want to trust a monarchy after all his antimonarchist actions which makes Europe out mostly, and several of the European nations hate him besides. Most of Latin America is out with him being one of the foremost antiCatholics of the day. Paraguay as I recall was rather anticlerical in this period and is also stubbornly republican ITTL. As for racial issues Jackson either cares less personally or just bears with it, and the Paraguayan dictator, whoever it ends up being, likewise bears with Jackson.
As for Jackson death ITTL either he is KIAed in the ITTL equivalent of the Triple Alliance, or is captured an executed for many outstanding crimes.
Now to wait and see how far off the mark I am.
