Okay, the question assumes that we won't find anything, and what happens then.
The same thing that happens if we do find something. The UN and coalition forces work to rebuild Iraq, without a maniacal dictator who orders mass attacks on people and whose personal guard slaughters innocent civilians who are trying to flee the city for their own safety.

The WMDs are still a concern, but that concern has faded in the face of what the Iraqi soldiers are doing to damn themselves. You don't jump up holding a little girl as a human shield and expect the world to still be on your side.

Last night on msnbc the Pentagon allowed an embedded reporter near Al Kut to broadcast a verbal description of what was going on during a firefight. His photographer was filming the whole time and the Pentagon was seeing that video, but the tv viewers just got to hear the audio.
An Iraqi soldier had taken a family hostage and was using them as human shields during the firefight. During the shooting, the Marines were doing everything possible not to hit this family (a father, a 13-yr old girl, and a small 3-yr old girl). Finally the Colonel of the troop put a bullet right through the head of the hostage-taker and freed the family, and the reporter (who is also a doctor) ran out to get the family down into their foxhole. (You should've heard the doctor when a helicopter flew in for support and started firing Hellfire missiles right over their head - "JESUS CHRIST! JESUS CHRIST!! HELL YEAH!!!!!!!!! WOOO!!!" right on the air, hehe.)

Being a terrorist isn't just about chemical weapons - it's also about terrorizing your own citizens and mass-murdering them for no reason other than the fun of doing so.

So nothing happens. The rebuilding goes on and the world rejoices because these terrorized people are free to live a life out from under the oppression of a murderous, raping dictator and his sons.
