There has been plenty of evidence found Don. None of it conclusive as yet. However, to claim no evidence is grossly misleading.

Please give me an alternative explanation for

huge stores of gas masks
huge stores of chemical agent treatments
buried precurser chemicals
buried equipment which can be used to make chemical weapons
tales of moving and/or destroying biological weapons related materials prior inspections
refusal to allow access to iragi scientists
over a decade of inspection obstruction
huge stores of normal weapons in violation of sanctions
missiles with ranges exceeding sanctions
numerous terrorist training camps in and arround baghdad
Feedayan terrorizing their own people into fighting a cause they didn't believe in
horrible stories of human rights abuses by the FREED Iraqi people
previous use chemical weapons

All of these show a clear profile of a person likely to want to have and use chemical weapons and evidence that he was in no way prepared to give them up. It certainly shows the sanctions program was very ineffective. But of course if we don't lay our hands on an actual chemical weapon many will say this war was not justified. That is exactly the same attitude that caused 911. You have got to make judgement calls on issues of high risk and go where the preponderance of evidence leads you. Whether or not WMD are found Bush and company were justified in believing there was a large risk Saddam had WMD and would be willing to share them with terrorists.
