Terrorist goal
The terrorist are trying to hit us in the pocket book. You have to admit 9/11 cost a lot when you include the lost air travel. Even then they would have to make a hit like that every year if not sooner to make progress in there quest.
Under a different president they might have come close to there objective in time.
Great question as to what Usama bin Laden has to smile about McFly. Nothing I can think of.
Hard to imagine the extreme Islamists thinking rationally anytime soon even though they are losing the fight.
