Philosopher Nassim Nicholas Taleb writes in Politico.eu that Saudi Wahhabis are the real driving force behind global jihad:
Since 2001 our policy for fighting Islamic terrorists has been, to put it politely, missing the elephant in the room, sort of like treating symptoms and completely missing the disease.
Policymakers and slow-thinking bureaucrats stupidly let terrorism grow by ignoring the roots. So we lost a generation: Someone who went to grammar school in Saudi Arabia (our “ally”) after September 11 is now an adult, indoctrinated into believing and supporting Salafi violence, hence encouraged to finance it — while we got distracted by the use of complicated weapons and machinery.
Even worse, the Wahhabis have accelerated their brainwashing of East and West Asians with their madrassas, thanks to high oil revenues.
So instead of invading Iraq, blowing up Jihadi John and individual terrorists, thus causing a multiplication of these agents, it would have been be easier to focus on the source of all problems: the Wahhabi/Salafi education and the promotion of intolerance by which a Shiite or a Yazidi or a Christian are deviant people.
