As for the situation in the US - I definitely hate that hawkish politicians rarely have any skin in the game. I might have a warped view living in DC, but the senior officer corp is often made up of generational military. And the enlisted soldiers are very often from disadvantaged areas. Having a volunteer military is a good thing, but it feels like (no data to back this up) we're well along the path of creating a military "caste" or two. If anybody has data about the family histories of current enlisted soldiers and officers, I'd be interested to see if my thought bares out.
