Talking Points Memo points out that Saddam’s recent behavior belies the claims that he’s a rational actor who wouldn’t use a nuke irresponsibly:
We’re about to go to war with Iraq. It may be a terrible idea. It may go badly for us. We may get bogged down there for years. But one thing is absolutely certain: it will go terribly for Saddam Hussein.
That’s right, he could prevent the invasion by cooperating with Blix, but he steadfastly refuses. The fact that he also insisted on invading Kuwait when a gigantic global coalition told him not to should have been the tipoff.
