texas does not become independent in a war. it plays out like    . there is never a free for all at any point. imho. and a conflict with mexico occurs later in the timeline when they feel that the us has lost more or less lost sovereignty which happens gradually and then all at once. texas will likely not be alone in such a scenario. i do see the likelihood of trouble with mexico at some point though, however my guess us that things are such a mess for everyone financially, economically, etc. that most would end up leaving texas in a protracted political crisis. they came there for greener and pastures and they will leave for the same reason. mexico won't challenge the us's claims over the territory though during a political crisis.
