USA-Prussia/North Germans-Russia-Mexican Republic
vs.
CSA-Britain-France-Austria/South Germans-Mexican Empire
Hmm...
Russia piles onto Austria with... marginal success, but ties up a lot of troops. Prussia kicks German Statelets to the curb, but France is on the move so it's gonna be interesting, though they also have the *crapsack* Italians bugging them. Meanwhile, Britain is pestering the Russians across the board, while landing some troops to aid the French/Germans against Prussia - though at the same time putting a great deal of effort into burning Washington D.C. for the 2nd time with Confederate help. The US will bleed themselves attacking the Confederates via the Shenandoah for a while (as per OTL) while also attempting to deal with a Royal Navy and Canadians. No one outside of Mexico is going to be doing shit inside of Mexico until their scarier enemies are dealt with... except maybe Napolean III...
