A must read on the roots of terrorism from Alan Krueger and Jitka Maleckova. Snippet:
Countries with more freedom were less likely to be the birthplace of international terrorists. Poverty and literacy were unrelated to the number of terrorists from a country. Think of a country like Saudi Arabia: It is wealthy but has few political and civil freedoms. Perhaps it is no coincidence that so many of the September 11 terrorists -- and Osama bin Laden himself -- came from there.
