This is the document that got us in to the War in Iraq:

March 18, 2003

Dear Mr. Speaker: (Dear Mr. President:)

Consistent with section 3(b) of the Authorization for Use of Military Force Against Iraq Resolution of 2002 (Public Law 107-243), and based on information available to me, including that in the enclosed document, I determine that:

(1) reliance by the United States on further diplomatic and other peaceful means alone will neither (A) adequately protect the national security of the United States against the continuing threat posed by Iraq nor (B) likely lead to enforcement of all relevant United Nations Security Council resolutions regarding Iraq; and

(2) acting pursuant to the Constitution and Public Law 107-243 is consistent with the United States and other countries continuing to take the necessary actions against international terrorists and terrorist organizations, including those nations, organizations, or persons who planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001.

Sincerely,

GEORGE W. BUSH

In other words, Bush was acting on a statute, having concluded (as he needed to) that Iraq was part of the group of people who "planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001."

Today, at a press conference, Bush said something different:

BUSH: The terrorists attacked us and killed 3,000 of our citizens before we started the freedom agenda in the Middle East.

QUESTION: What did Iraq have to do with it?

BUSH: What did Iraq have to do with what?

QUESTION: The attack on the World Trade Center.

BUSH: Nothing.
