They only turned to the WMD angle after they weren't able to connect Hussein to al-Qaeda.
And who made everyone believe that he had WMD's? Did the bad intel gather, organize and present itself?
Who ran the OSP? Since we already had existing itelligence gathering and analysis chanells in place(CIA, DIA, etc), why was it even created in the first place?
So again what is your conclusion? That we were duped into a war against our interests by parties operating for the benefit of Israel? If you believe that you are a Jew hating conspiratorial nut.
