While nation politics is not something communists like do to it is something that occasionally must be done. Restoring the 1846 Mexico-United States border would go a long way towards enriching the global south. Obviously there would still be the issue of Indigenous land rights, it would be the responsibility of Mexico to give these nations equal representation. But it would still be the United State’s responsibility to pay reparations in perpetuity should the United States still exist.
The island territories of the United States could easily become independent should the US military just leave. Coalitions would probably form in the Pacific and the Caribbean for the purpose of trade. Cuba would act as the defacto capital of any Caribbean union, southern Florida could become apart of a theoretical Caribbean nation and to a much lesser chance the Yucatan and the coastal region of Venezuela could join as well. The Pacific would be much less organized on account of its vastness, New Zealand would have a large amount of control if the white settler government could be expelled, but it’s control would be less than that Cuba would have. Hawaii would act as a defacto second capital since distances are so vast. Islands in the Pacific would have to be much more juche then any Caribbean union would have to be.
If the United States is to be broken up then a New Africa would probably emerge from the south. Indigenous nations within this New Africa would presumably be treated in the same way Mexico would be expected to treat its Indigenous nations within it (irl Mexico probably could do better but let’s just assume that there was some reform). New Africa would have territory that would span the entire area of where the confederacy once was and outside of it, negotiations between it and Mexico would have to be made where there territory would overlap. It would have a good 2/3’s of the Mississippi River in its control. It would control cities like Baltimore, Philadelphia, and Chicago. Its borders would have to extend into territory that wasn’t traditionally apart of the Black belt to avoid exclaves. DC would definitely join a Black nation if one formed in the US, which would necessitate relocating the US capitol should the US still exist in any form.
Assuming all this is done, what would be left of the United States would be just the North East, Midwest, and Northwest. But here’s the craziest idea from all of this. What if Canada annexed parts of the United States? Let them take everything below the 45th parallel. That would give them much of the great planes, it would give them Seattle, and parts of Maine, it would give them a land border with new Africa from the Chicago land area. Why should we destroy Canada? It can be reformed in ways the United States cannot be. What would be left of the United States would be a New England rump state, a Pacific north west rump state, and nothing else. It would still be coast to coast but it would be separated by land connection. The global south could tax the fuck out of that.
Also just for fun Alaska gets returned to Russia.
Wrong.
