Bitter Lake is a 2015 BBC documentary by British filmmaker Adam Curtis. It argues that Western politicians have manufactured a simplified story about militant Islam, turning it into a good vs. evil argument informed by, and a reaction to, Western society's increasing chaos and disorder, which they neither grasp nor understand. The film makes extended use of newsreels and archive footage, and intersperses brief narrative segments with longer segments that depict violence and war in Afghanistan.
