Your cynicism is grounded in ignorance. Bush is not afraid of anthrax attacks on U.S. soil. (No one in the administration is especially afraid of anthrax attacks anymore.)
Nukes are a whole 'nother matter. But the nuclear threat is why we need to advance the timetable, and the POTUS knows that. He will not wait forever on the U.N.
Kofi has been FURIOUS since Bush slapped him down during the UN speech.
He has actively worked to get ANY agreement that Bush is not a part of.
Now he has this one, which he will use to ram his own agenda through, inserting inspectors, while smugly acting like Bush didn't know what he was talking about.
Bush backs off, after much rumblings about 'yet another chance for Saddam not to comply."
Inspectors go in, give Iraq their seal of approval.
Of course, then something happens.
And the UN is, for all intents and purposes, destroyed forever and ever.
