One day after he proclaimed that it is "not too important" when U.S. troops return from Iraq, John McCain commemorated an unfortunate five year anniversary. In the annals of McCain's dismal record of flawed forecasts and calamitous calls on Iraq, June 11, 2003 stands out. On that one day, George W. Bush's would-be Republican successor both defended his proclamation of mission accomplished while insisting that Saddam's weapons of mass destruction would surely be found.
As MediaMatters documented, McCain's daily-double came during an appearance on Fox News' Your World with Neil Cavuto (video here):

NEIL CAVUTO (host): Senator -- after a conflict means after the conflict, and many argue the conflict isn't over.
McCAIN: Well, then why was there a banner that said mission accomplished on the aircraft carrier?
Look, the -- I have said a long time that reconstruction of Iraq would be a long, long, difficult process, but the conflict -- the major conflict is over, the regime change has been accomplished, and it's very appropriate. In two weeks, General Franks is going to come before the Senate Armed Services Committee, and we're going to have his overall assessment of the conflict. I think that's entirely appropriate because we'll be -- we'll be taking up the needs of the Defense Department and the men and women in the military on the Armed Services Committee.
But I'm looking for an overall review of the conflict, what we did right, what we did wrong, and what the needs are, including the issue of weapons of mass destruction. I remain confident that we will find weapons of mass destruction in Iraq.

Despite the aggressive efforts of his campaign and its allies in the conservative echo chamber to rewrite the Arizona Senator's abysmal record on Iraq, the history shows John McCain like President Bush was sadly wrong at almost every turn in promoting the invasion and occupation of Iraq. From his predictions of a short war and claims U.S. troops would be greeted as liberators to his announcements of mission accomplished, his ongoing confusion over friend and foe in Iraq and so much more, McCain's is an unbroken legacy of error.
And no doubt, among John McCain's years of mistakes when it comes to Iraq, June 11, 2003 was among the very worst.
