Modelling himself as the second Justinian, the Pacific Prime Minister proclaimed his Government was the American incarnation of the Byzantine empire, and pledged to reunite the United States. This metaphor would become even more potent with the collapse of the Eastern American Government (CDC) after its forces were overrun through the coordination of several fascist and military states. This opened the door for the Pacific Government to march across the nation, take Washington DC, and reunite the state.
The decades-long campaign was grinding, and Pacific forces often found that captured territory quickly fell into a state of simmering insurgency and terrorist activity. In the end, the Pacific Government would come the closest any single faction would come to reuniting the country. Through the loss of countless lives, superior military organization, and more funding, their military managed to puncture through the Midwest, following the largely intact highway system there to roll over any opposition. The dream of reunification seemed the closest it could ever be as the Pacific Government defeated the Baltimore clique at the Battle of Washington DC and marched into the city. Upon hearing the news of the Battle, the Pacific Prime Minister quoted Justinian, saying "Glory to God who has thought me worthy to finish this work." as he believed this was the realization of his life's work.
Most Americans had believed that once any credible government marched into DC all fighting would cease and America would slowly fall back into a state of peace. This was not the case. The many fascist, leftist, and theocratic factions were too thoroughly entrenched in their territory and resolve. Further, secessionist states, like Texas, refused to join the Pacific cause because they believed their government and values had deviated too far from true "Americanism." So, as DC fell, Americans stopped their squabbling, let it sink in, and then resumed the carnage. It was in this atmosphere that the dream of reuniting America died. When only a few minor states joined the Pacific Government after the Battle of Washington, it became clear that holding the territory was impossible. With too many militarist states surrounding the new long arm of the Pacific Government, withdraw became a strategic imperative. As it turns out, the Pacific had created the means of the downfall. In eradicating the Midwest governments during their march, they had eliminated the forces stabilizing the region, radicalized its population, and united the surrounding states against their common threat. It is said that the entire population of the Pacific wept as images aired of their military marching out of DC to return to fortified positions in Iowa and Missouri.
Though they declared they'd return, the Pacific Government never managed to muster the strength to combat the Eastern states again. A series of cyber attacks crippled much of the infrastructure within the Pacific government’s control, and ultimately served to birth a more domestically focused nation. The power vacuum left by their withdraw allowed the rise of the communalist state of Columbia, which would ultimately pacify the Northeast and much of the Atlantic coast. After the Pacific effort there would be no other large-scale attempts to restore the old United States, and the once great nation fragmented into many new peoples.
In this scenario, the "rebels" are any none federal faction and they do win. Had the Pacific government won, the United States would have been restored as a political entity across its former territory, but instead it collapsed into many states like Rome.
They got everything west of the Rockies, they got the Bays of New York and the Chesapeake and they got New Orleans... So the war's already over. With those territories you have the bulk of the US economy, all the ports that really matter, and the means to move up the mississippi and into the Great Lakes.
After Canada gets angry They would join in when probably 40% of the grey area on the map disappears and the anarchy factions can’t handle a two font war so the war would only last 2 to 4 months after the declaration of canada (I think you should make this as a kinda of a request)
I think Canada would be too weak to intervene in America without an international coalition. They’d be dealing with all the economic effects of America’s collapse plus millions of refugees. It’s probably make for an unstable and xenophobic Canada.
The millions of refugees would be eager to get back their home and would be fresh troops but the separatists would trigger their hand by being discovered to be sending weapons to the québécois people for a possible invasion and insurrection and england would be outraged and would send a invasion force to land on a unprepared New England and the separatists attacking Ottawa would be a final straw , being put into a corner the rebels would attempt to seize canadian towns for supply’s and weapons to fuel their war machine
Interesting map and story. Regretfully the suspension of disbelief was lost with the reference to an American Byzantine empire. No American leader would ever advance such a concept, as few Americans know what the Byzantine empire was.
