Your #25 properly questions the lack of wisdom inherent in adopting the CW model used by backward, less technical societies.
I’ll add it seems unwise to equate physical defense of the Constitution as a civil war.
We certainly do not regard violent, but appropriate law enforcement as civil war.
The Constitution is the high ground, and we own it.
The wrinkle comes when, during the sensible approach you advocate, those both internal and external who hold an anti-American agenda employ 3d world Odinga-like tactics.
Unfortunately, and without addressing here the means they could employ, it seems likely they could obstruct the controlled excision we would like to see.
You make good points in your reply. Of course, the commies may resort to brutal tactics of mass punishment. After all, that's their model for societal control.
I'm by no means an expert or especially learned in this area but I think that, given the general American character, they would have trouble recruiting and controlling military or police personnel to commit atrocities on the scale needed to cow the population. I could be wrong on this point but I would hope not.
The traditional defense against cell structure action groups that are implied in our discussion is infiltration. If the authorites can mobilize enough resources to efficiently infiltrate and nuetralize these cells quicker than they can be formed and put into action then they may be successful in obstructing their usefulness.
But this is all theoretical speculation and who knows what may happen in the future and what events may lead to their necessity. Equally, who knows what the outcome may be.
