My point is that Bush had numerous valid reasons to invade Iraq based on intelligence from the CIA and other allied intelligence agencies.
What valid reasons are those? I understand Bush had many reasons, but my interest is in what you presume to believe the 'valid' reasons.
I stated that he did not need UN authorization, but my reading of Res 1441 says he did have authorization.
Reading 1441 does not resolve the problems with your argument. The language in 1441 does not authorize the use of force after 1441 was passed. There is no autonacity or trigger to use force. Only the permanent and acting ten members on the UNSC had the authority to authorize military force or other consequences if Iraq failed to take its final opportunity to comply.
Iraq was not cited for any hard core violations that were egregious enough the the UNSC was required to convene to decide the matter of consequences.
Your reading of 1441 is in error.
Bush did not need UN authorization because what he actually did was renege on his committment to peaceful disarming of Iraq through 1441 in order to go down the path of preemptive self defense.
That is not legal under the UN Chartet by any means. Only Bush supporters go along with that case for starting a war.
Read a little on it here:
After months of trying to roally international support for a war and a two-day ultimatum demanding that Iraqi President Saddam Hussein step down, the United States attacked Iraq on March 19, 2003. The goal, U.S. President George W. Bush said in a speech, was "to disarm Iraq, to free its people and to defend the world from grave danger."
Experts disagree as to whether the war was legal under international law. Under Chapter VII of the United Nations Charter, to which the United States is a party, a nation's use of force is authorized under only two circumstances: in individual or collective self-defense, as outlined in Article 51, or pursuant to a Security Council resolution, as outlined in Article 42.
Self Defense
Since it was not directly attacked by Iraq the United States did not have an obvious right to self-defense. The administration, though, argued that it had a right to defend itself preemptively against a future possible attack.
