"The major exception here is the Department of Defense, which has an ‘open’ but barely publicized relationship with Tinsel Town, whereby, in exchange for advice, men and invaluable equipment, such as aircraft carriers and helicopters, the Pentagon routinely demands flattering script alterations."

Do you recall any big American movie in the last decade (or even more) that painted America's military in a non-positive light? I don't. I do remember Zero Dark Thirty (if you watch carefully you'll see how they basically say that torture works great in getting prisoners to hand over information), I do remember The Hurt Locker, and a whole list of other movies, Iron Man and Captain America being the latest examples (Iron Man originally used to be about fighting communism, now it is about fighting terrorism).
Hollywood output is a very valuable export to the world in this way of framing America's image in the world, and I'm betting America is becoming even more aware of this and will put even more resources to this effort in coming time.
To me, truly the most amazing thing about this is that pretty much no-one knows about this! Tell someone that there's a lot of American propaganda in Western movies and they'll take you for a conspiracy nut.
