Man...this isn't news. Long before the war many high ranking officials (Powell, Rice, etc.) publicly stated that Iraq did not pose a serious threat to us. Then all of a sudden once war became an option they seriously changed their tune.
What's the purpose of this war? Pride, pure and simple. I find it interesting that the only common name that comes up when discussing those who have taken on Iraq that isn't Iatolah or Shah, is Bush. Regardless of whether or not Bush is fighting a war to make daddy happy (and by fighting I mean sending a lot of other folks off to die), he's still doing it to prove that quite simply he can. With no real evidence that Iraq posed any threat to us at all, how can there be any other concensus?
