Why We Fight
For anyone interested in learning a little more about the American Military-Industrial Complex, I'd recommend the recent documentary Why We Fight. Released in 2005, the film uses Eisenhower's parting address as the centerpiece of a more involved look at the complicated relationship between researchers, workers, corporations, the military, and politicians from WWII to the present. It's definitely worth watching regardless of your politics.
The text of President Eisenhower's speech is posted online, as is video.
