How much easier would it be to have a convention of states and write into the constitution huge limitations of power of the feds? Would be a h*ll of a lot easier than taking on the United States Armed Forces!
Remember all those videos from Iraq of the smart weapons blasting to h*ll a bunch Iragis? You don’t think they would use them on us? Just sayin....
Hellfire missiles, the most commonly used weapon that you referenced, cost over $58000 a piece and are in limited supply. There are 330 million people in this country. Do the math.
