hey, all. i've been going over late-18th century history again for Anglo-American Rivalry, and a possibility occurs to me. first and foremost, the US doesn't get all of its OTL territorial gains, so its international as well as internal borders will look quite different by TTL's present-day. that's sorta beside the point, though.
one thing i'd like to explore is the possibility of other territory that's not part of the OTL US joining the union of Anglo-American Rivalry. one that comes to mind is, potentially, a second California Republic comprised mostly of the Baja Peninsula, because the area is largely cut off from the rest of Mexico by desert. another possibility that comes to mind is Haiti, possibly butterflying in notions of statehood among the Haitians and partly to rub it in the nose of the former CSA (assuming such events come to pass ITTL; i'm still writing it all)
Baja Republic and possibly Haiti aside, does anyone know of other regions that want or wanted to join the US IOTL? i know there were times when at least parts of Canada considered it, but what else?
