Osama, the psychopathic mass-murderer, has received the relgious blessing to nuke an American city (we'll see if he keeps his campaign promise to only attack red states). The authority to proceed and nuke America in the name of Allah came by way of permission from a Saudi cleric, a holy man.
How do we respond? My suggestion is that we promulgate to the world that the official American foreign policy, if nuked under such circumstances, is simply to nuke Mecca, and then some. Why not? Remember our Soviet policy of M.A.D?
