Good luck taking down an armed military with your plinkers, if they actually WANT to get rid of you. Or they could, you know, keep doing the slow-boil that they've been doing for years. That seems to be working pretty well - as you already note yourself. Why fight them when you can just make them agree with you?
The question becomes whether the members of the US armed forces are actually willing to turn their weapons on their neighbors, coworkers or friends? It's one thing to be deployed to a different country in a distant land against a population that differs from you in ethnicity, beliefs, etc. The brainwashing needed there is fairly low level, of the patriotic sort. To view large groups of people from your own country, your own neighborhood, your own church as a mortal enemy that needs to die takes things to a whole different level.
