I repeat what I said above if they knew we were hit they would not cause public panic anymore than an asteroid hitting earth. People are already ignorantly buying useless defective Russian masks at their local army navy store.In other words panic buying when they have zero training to use.
Logically I believe we are wise in awaiting revenge as Bin Loon wants us scared but does he have nuke suitcases and more sick surprises. Phsy warfare is very much an issue and it is a different type of war.
I am certain you are right about the government not wanting to create panic. And I am certain that bin Laden's terrormongers have suitcase/briefcase nukes and worse.
