I am not sure what you meant by this statement.
I believe that we already know the truth of the WMD story.
What we don't know is where the remaining stockpile is, or how and when it was disposed of, or where it was hidden or sent to for safe keeping, if that is the case.
As to the bio aspect, we know that there was a active program to produce it, but from the information gleaned so far, it appears that no major quantities, (other than anthrax) were produced for a weapon. It appears that most of what they had was chemical in nature.
Personally, I think that much mis-information was put out by the Hussein regime to keep the U.S. off balance and also keep his own people confused on the issue. I believe that the bio and chem programs were mothballed after the first conflict in 92 and much of the stocks were in fact disposed of or sent out of the country. I think he kept enough equipment and precursor chems to quickly go back into production as soon as the U.N. inspectors finished their job.
Unfortunately he was so cocky about his situation and so sure that France would protect him from invasion that he never allowed the inspections to finish and sanctions to lift.
He had to give countries like Iran the idea that he had WOD ready to deploy so that they would not take advantage of a perceived weakened defense. Unfortunately for him, this ruse also caused his ultimate downfall. He sure was a dumb SOB.
I think that there is much more evidence buried in various places in Iraq. I also think that France, Russia and Syria helped him to hide some things.
As to the truth of the matter, it is so obfuscated by lies that no one will believe any one truth about what happened.
Even if the truth is out there it will never be something that can be said to be the whole truth and nothing but the truth.
