I'm not sure the Founders would agree.
Well, I'm not sure the founders would agree with having a literal Federal Army made up of FBI, ATF, HSA, IRS and various and sundry other federal leo's that operate quite freely and with little or no responsibility or accountability for their actions.
Additionally, the US Military is not a monolithic force that is loyal to a leader or party. If ordered to react to "internal disturbances", I feel the military would respond as ordered. If/when it became apparent to the force structure (PVT to GEN) that they were being told to engage in either unconstitutional or illegal acts against the American public, at the very least you would see them sit on theri hands. Not to go back to a weak arguement, but if you've not served in our military, you don't understand. We really do have a "citizens" military with many, many very sophisticed folks from top to bottom that can think and analyze situations independently.
I stand by my statement that the US Military is not what is to be feared, but the Federal "law enforcement" agencies are.
