Privates are robots who shout YESSER!, Sergeants are PTSD ridden drunks and sadists (and usually have some type of incurable venereal disease which keeps them out of combat which is why they are sadists), junior officers are bumbling ernest dolts, and senior officers are almost always engaged in some nefarious conspiracy to something something gazpacho. And they're all just itching to overthrow democracy and probably kill a lot of people in the process because there ain't nothing the boys in uniform love more than killin' -- unless it's stealing boxes of gold from Saddam's palace. It's always the same.

Maybe this is generational and I've not seen the right movies, but other than the bit about Privates shouting "Yes sir," that's the exact opposite of how I've seen the military portrayed by Hollywood.  And everywhere, really.  Thinking of conspiratorial military episodes -- I dunno, The Rock?  And even then, it was a small unit of Bad Guys^TM who became Mercenaries^TM.

People trip over themselves -- in and outside of the media -- to glorify the military.

As he noted, Kent State was 46 years ago.  And I assume the movies he's thinking of are of a similar vintage.  What is he on about?

Be nice to America. Or we'll bring democracy to your country.
