Idiot. If it ever did come down to an all-out war pitting the U.S. military against the people, the military could barely prevail over a state. NO WAY could they take the entire country, not even close. Why? Because you don't "own" or even control terrain for very long without sufficient boots on the ground and the military doesn't have even a tiny fraction of the people it would take. Not only that but once on the ground in that capacity, they're highly vulnerable and if every American civilian with a gun became an insurgent, the U.S. military would suffer an epic defeat.
