" Secede" from the union, not "succeed." Anyway, not gonna happen. Tried in 1861 and it sorta went sideways a tad.
That was for all the wrong reasons. Its a little different this time.
Secede.
We have reached a window where it can still be done bloodlessly since the new regime has yet to consolidate their power. Once that happens, say in a year or two, they will have the Pentagon restocked with politically reliable officers who will have no compunction against disbanding the National Guard and using the active military to subdue the Red states by force.
Yes, it will be rocky. Yes, it will be scary- but it can be done with words and paper. The longer we wait, the more likely it will happen anyway, but with fire and blood.
We have reached a point where half the country is unwilling to live under rules dictated by the other half. We have no common bonds of philosophy or culture anymore. A nation may persevere without a common language or religion, but NOT without common values.
The best option is to shake hands, wish them well, and let each side forge a new way forward seperately. Time will tell, and history will judge who was right. Hell, theres no reason the successor States couldnt reform a union again at a later date, if they agree to- or even form a different sort of defense and trade coalition without social authority over each other.
The Red states must call for a new Constitutional convention. Indeed, given the geographical realities of the cultural divide, it may become necessary to form 3-4 new nations. So be it.
Better this than the alternative- a rehash of 1861.
