Instapundit links to John Scalzi, who believes, as I do, that we must fight, but that the Administration has incredibly bollixed up the situation:

If Bush and his people had the slightest bit of competence in dealing with the rest of the world -- competence that should have begun on January 20, 2001, not just in the last six months or so -- this war would already be over. There would have been no real dissent in the Security Council, no ability for Saddam to play other countries against us, less time for the "no war ever under any circumstances, ever" crowd to build up its head of steam, and we'd have had international support for a war that would be both useful and had the potential to eventually be a humane action. Saddam would probably already be dead (or rotting in a dinky little cell, which I would prefer) and the UN instead of the US would be stuck with keeping the various hate-filled factions within Iraq from gleefully murdering each other. We would have gotten what we wanted, and we would have made it look like a team effort. Then everybody could have had their Coke and gone home.

Glenn gives Bush & Co. credit for bending over backwards to make the UN process work. I don't think there was that goal in mind. I think there has been no coherent long term strategy in preparing for war, or whatever. Like the Energizer Bunny, the situation just kept going, and going, and going.
