From Foreign Policy:
There seems to be a pattern of mediocre sons from elite families becoming terrorists.
Osama bin Laden’s dad was a wildly succesful contractor with close ties to Saudi royalty. Underpants bomber Umar Farouk Abdulmutallab’s father was a prominent Nigerian banker and one of the wealthiest men in Africa. Perhaps they feel like failures next to their successful dads, and militancy offers a pathway toward self-respect.
