Sounds like a smoking Gatling gun to me

“mobile biological weapons labs”
nerve agents
“some followers of a senior associate of Osama bin Laden are currently in the Iraqi capital, with the approval of Saddam”
To paraphrase Secretary Powell, not once has Hussein proven that any WMD he is known to possess has been destroyed. For the hard-of-understanding among you (read: “liberals”), just because a known liar says he has destroyed a weapon of mass destruction, and you find no evidence of said weapon of mass destruction, doesn’t mean said liar has destroyed said weapon of mass destruction. It just means it isn’t where it used to be.
