There's a movie out there called Why We Fight, named after the old WWII propaganda movie series, this is a modern on that's been on TV in Britain and I think in a good number of English speaking countries, certainly the Commonwealth ones, but is very underground in the USA, you'll never ever see it. It IS possible to see it, there's a low-res .ra file of it out there on the net, no I can't tell you the link, or I could tell you but then I'd have to kill you ha ha. Just look around, if you're lucky you may find it.

It's very very well done, if you are lucky enough to find it you'll watch it several times. It interweaves the story of a man whose son was lost in 9-11 and fell for the "It's Saddam's Fault" propaganda hook line and sinker, and gradually finds out it was wrong, with a run-down on US history showing our propensity to be at war with someone, anyone, preferably anyone with oil or markets we want to exploit, on a continuous basis. No matter who is in the White House.  

Fleam's right, good movie:
