The recent refusal of Iraq to destroy the missiles helps to garner world opinion also which the latest Blix moves have accomplished. We don't need world opinion, but it makes the task a lot easier.
War is inevitable...but the more Saddam and the left are seen to be complete wackos the better.
Also, since Sadaam has refused to destroy these missiles, it's obvious that he's never destroyed any of the other stuff either. Why start now? Anybody, and I can think of a number of morons on the left, who actually thinks that Iraq has destroyed all their WMD is kidding themselves. This guy just proved to us in his refusal to destroy these missiles, that he's surely never destroyed any of the other stuff he's got.
