Strick, it's about as possible to wipe out Al Qaeda as it is to wipe out all asthma. Both are symptoms of bigger problems. You can't kill the symptom in these cases. You can either try to limit them, or you can correct the problems that cause the symptoms.

In the case of Al Quaeda, the problem is caused by the way powerful countries like the US treat weaker countries like Afghanisan. Trying to "wipe out" the symptom in this case will only make it worse.
