James Joyner is on top of things Saudi, but I have to qualify one of his statements where he argues that the terror threat does not come from the poor and educated, but from the well-trained sons of the affluent. The latter is certainly true but these well educated guys have a far better chance of succeeding and getting on the ground support in a country where a rapidly growing segment of frustrated, poor and uneducated youth is looking for a way out of their dismal lives. It takes a certain type of intellectual to achieve this, which is why the Russian Revolution and Nazism succeeded and why for instance equally radical groups such as Baader-Meinhof and the IRA failed: a prosperous, employed, freedom enjoying middle-class is probably the last group of people to be mobilized behind a radical ideology that seeks to overthrow the current order. Given that and the incompetent and divided leadership that currently rules Saudi Arabia (think about the analogies with the Weimar Republic and the last Czar) Saudi Arabia is poised to be the defining battleground in struggle with Islamist terror.
