No, we were not unless you want to believe the Michael Moore view of things. Who lied about what? Everyone from Clinton, the UN, the CIA, neighboring states, thought Saddam had WMDs. If he did not have them then they were all wrong or all lying. I doubt if most of that crew lied to get us into Iraq. Are you back to a conspiracy coming out of Jerusalem?
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?
