If the States each had their own citizen militia and had to pay 'em, we'd see a lot less casual use, especially by the Federal level. "But," you might ask, "how would our great nation project force? How would the US maintain our prestige?" To the first, maybe less often by beatin' up the fuzzy-wuzzies and more often by bein' the kewl kids everyone wants to be like; to the second, can you eat, smoke, drink or sleep with prestige? If not, just what are you doin' with that stuff, anyway -- more to the point, what's Congress do with it? Pick up dates? "Hey baby, wanna see my prestige?" Ew. They'd do it, too. You know they do.
Relatedly, I was bothered when (well, when I found out) the Feds -- was it during Gerald Ford's Presidency? -- took a sort of Cub Scout Oath not to surreptitiously bump off foreign leaders. Seems to me a lot of lower-ranking bloodshed could be spared if this
...Please bear in mind that I am rather determinedly civilian and inherently anarchic; there's a huge lot of .mil stuff stuff I just don't get and cannot grasp. I support our troops and as for the nation's present engagements, go look up what Ayn Rand said about Vietnam. (Hint, it wasn't at all akin to the non-plan the Junior Senator from Illinois is flogging, which appears to involve slouching home and leaving whatever mess behind there is when the music stops).
Okay, try not to be too blamed mean about it; I'm sure my mad plan would do stuff like sour the milk and corrupt the youth. Me and those dead white guys, what'd they know anyhow?
Pity's sake, even they changed their minds. Kind of. Go read what scholars say.
Update: closed comments, I was getting on my own nerves.
