Islamic religion is at its core pacifist, and generally looks at the extremists similarly to how we would look at christian abortion clinic bombers, for example.
Surely you guys don't want to eradicate all southern baptists?
An IRA bomb means all catholics are radical loons in need of extermination?
Protestants terrorizing children in Ireland means we need to kill them too I guess.
Of course, a lot of the anarchy world trade riots are led by athiests, so those have to go as well.

What is needed is to find the leaders, who are not suicidal and instead are quite cowardly hidden safely away as they send their followers to kill themselves. I'm all for cutting it off at its head, quite violently, and anyone who gets in the way of that. If it is indeed led by Ben Laden as is the most plausible at this point, then I'm all for going in and getting him. If the Taliban refuses to allow it, then I pity them, I would consider it cooperation in an act of war.
