I highly suggest reading up on asymmetrical wars fought throughout history. It is effectively impossible for a conventional army to track down and eliminate forces that merge and move seamlessly within the citizenry. The only group that’s ever had even marginal modern success with slowing (not stopping) a guerilla threat is Israel, and that’s because they don’t give a shit about leveling civilian areas and massacring innocent women and children, and movement in/out of the extremely small geographic area of Palestine is restricted by multiple (fortified & mined) borders on every side. There is zero chance any military force, even our own, could segment and subjugate our ENTIRE country like Israel has Palestine, nor would they have anything close to local popular support to pull it off if they did.

That trillion dollars is designed to fight conventional armies and extremist Islamist terrorist cells in Africa and the Middle East. Our military apparatus is simply not capable of stopping any single individual, or small group(s), from randomly deciding to crash out. Unless the NSA/CIA/FBI/WTF/BBQ suddenly gain the power to read every person’s mind, there’s not a thing wealthy sociopaths can do to effectively wield the military against citizens in a way that makes it safe for those same sociopaths to walk down the street.
