texas can't be a country unto itself precisely because of that: demography. if it were to secede the ensuing crisis on the border would be donbass 2.0 and it would probably be invaded by mexico. the region stretching along the border is a no-go zone for any white texan, it's understood that it's part of the state in name only, it's governed by local mexican democrat politicians who are a pillar of the state's democratic party. technically, texas does have treaty rights deriving from the treaty of annexation with the united states that allow it to divide itself into five separate states at the time of its own choosing. it could thus eject the mexican borderlands and form a confederacy or federal republic out of the remaining four regions.
