The Power of Nightmares
This film explores the origins in the 1940s and 50s of Islamic Fundamentalism in the Middle East, and Neoconservatism in America, parallels between these movements, and their effect on the world today. From the introduction to Part 1:

"Both [the Islamists and Neoconservatives] were idealists who were born out of the failure of the liberal dream to build a better world. And both had a very similar explanation for what caused that failure. These two groups have changed the world, but not in the way that either intended. Together, they created todays nightmare vision of a secret, organized evil that threatens the world. A fantasy that politicians then found restored their power and authority in a disillusioned age. And those with the darkest fears became the most powerful. " The Power of Nightmares, Baby It's Cold Outside.
