Based on the snide tone of condescension, this response sounds like it was written by precisely the kind of delusional macho wannabe who fetishizes firearms and dreams of one day murdering someone.
Or maybe I've read just a little bit of history and think you're the delusional one.
Civil wars don't go down like foreign occupations. If this nation breaks down into widespread violence (I don't personally think it would, I think it would balkanize before we ever got to that point) I hope that you live long enough to be subject to is so that you may learn an important lesson and that some future generation may be spared the task of mopping up the mess.
That's exactly the problem: you've read some history and now you think you're an expert in civil war.
IDK. Ask the Irish.
The Taliban, VC, etc, had basically ZERO ability to mess with the invading army's supply lines or the political process keeping those supply lines open. Furthermore, the martial law steps taken in places like Iraq to stem the violence would be much more politically costly domestically. I can crap out plenty of non-US examples of this kind of thing if that helps.
This shit is all basic stuff covered in Armchair General 101. Educate yourself.
