Your theory does nothing to explain why so many women of my acquaintance support going after Saddam.
Unfortunately, Saddam doesn't have an ICBM to deliver the device he may or may not have. That means he will have to rely on a more primitive means of delivery such as a barge or container ship. No warning, not track.
I guess some people won't be happy until a device goes off in San Francisco or New York harbors. Of course then they will jump up and down screaming that we can't retaliate because we don't have any proof the device came from Saddam.
