You think it's a coincidence that progressives are so chummy with Mexico? If we secede, we will have a serious war on our hands.
I know, I'm just pointing out that we would have two nations of hostile invaders to defend against. Texas is both energy and food rich. We can definitely survive on our own, but I don't think we have the resources to fight a land war on all sides. The USSA will need those resources back and Mexico will gladly take their piece, too.Either way we have a war on our hands.
It would make sense for OK and the western states to join us, but I just don't see them really adding much to the fight. Just more resources for the new republic to defend.
