"Leading scholars"...hmmm, let's see - they aren't elected officials, so, why should we listen to them? Besides, while the claim of "that the 1991 use of force resolution ceased to be effective once Iraq capitulated to U.S. and allied forces in April 1991." might or might not be proven true (I'd argue for the latter), if they are "Leading scholars," as purported, they should also have the wisdom to look at other Congressional resolutions, mainly, the one passed on September 14, 2001, giving the President authority to prosecute the new war. If they are true scholars, they should know the basic persuasive principles of primacy and recency.
Democrats have no one to blame but themselves, and, the more they cry out against a war, the more cowardly they appear, and the more emboldened Saddam, with or without nukes, becomes.
Bull's-eye.
