That might mean "jack ****" to you, but it likely means a hell of a lot to many of them. Will this stop extremism? No. There will still be people on all ends of extremism...from those who physically carry out attacks to those on the lighter end who proclaim the need for retribution killings in America but don't make a peep when the situation occurs in reverse. And Al Qaeda is likely to still continue on as it has been. But because it doesn't change anything operational doesn't mean it doesn't do jack ****.
