@kr's post today about U.S. lawns reminded me of a great documentary about the power of fear and how it is used to gain political power. You can't go wrong with an Adam Curtis documentary but this series is especially great. The series discusses the origins of Neo-conservatism and Islamic terrorism and what they have in common.
