Ignatius: Sageman's Leaderless Jihad

Here's David Ignatius, one reference I've run into today to Marc Sageman's Leaderless Jihad.

This is important stuff...but, of course, you won't see it on CNN.

Sageman's a former CIA man and a forensic psychologist. He's collected data on 500 jihadists--data on what they believe, why they fight, and so on. His conclusion: we've been radically over-estimating the threat and, in fact, making it much worse, especially (no surprise here) by our actions in Iraq.
