The document, an intelligence report from February 2002, said it was probable that the prisoner, Ibn al-Shaykh al-Libi, "was intentionally misleading the debriefers" in making claims about Iraqi support for Al Qaeda's work with illicit weapons.

Bluntly, it was recognized well before the war in Iraq started that it would have nothing to do with the war or terror. Since we also know that those WMDs were a lie, what then was the valid reason for going into Iraq?

To put that in plainer terms, with no national security interest, those interests were being easily handled under the UN sanctions US presence in the gulf already, and certainly nothing amounting to either a clear or present danger, the war in Iraq is best classified as "waging agressive war."
