Second: As far as using nukes goes I don't think that it's possible unless we could localize a large number of terrorists in a desolate geographic reigon where the fallout would have little effect. Same goes for chem/bio weapons, the damage to the lands outside of the target area makes using them nearly verboten outside of extreme emergency.
Now, if we could find some way to nuke just Osama, I'd be all about that. :)

Seriously--if they, say, nuke Chicago--what is the downside of nuking Mecca and Medina?
