That is not the case at all. The justification for the war was that the Iraqis were not cooperating with the U.N. Security Council resolutions and the Security Council was not adequately enforcing their own resolutions. Why do you think we wasted all that time farting around with those guys, trying to get them to do their jobs?
That's the price the U.S. paid to get Great Britain on board.
It's hard to make the case here on FreeRepublic that Iraq's violation of U.N. resolutions constituted legitimate grounds for war, since most of us here never gave a rat's @ss about the U.N. to begin with.
