To start, Senseiman, I think most of your arguments ignore the mindset and knowledge of people at the time and are made with the benefit of hindsight.

Well, it seems only natural that it would be difficult to get consensus for regime change under the justification of a humanitarian intervention when there isn't any existing humanitarian crisis to stop or prevent. Saddam wasn't violently putting anybody down at the time of the invasion nor was there any reason to believe he would at any point in the forseeable future. The humanitarian justification would seem to fall apart on that basis alone, but when you consider the scale of the easily predictable humanitarian crisis the invasion provoked it just seems so divorced from reality as to be totally incomprehensible that anyone would take up that argument.
First off, Saddam was violently putting down his own people, up until 2003. Security forces were regularly executing Shias and Kurds, most recently as the 1999 Basra Massacre. This wasn't going to stop. Regular intimidation via random interrogations, torture and executions occurred daily. It was an ongoing humanitarian crisis, one that had occurred time and again since 1988.
Secondly, I fundamentally disagree with your point that the current situation was "easily predicable." Hindsight is 20/20, and the outcome was dependant on how the Administration handled the situation. Before the invasion, experts in post conflict reconstruction, were divided on the possible outcome of the invasion. Personally I wasn't sure either (I was involved in post conflict reconstruction research at the time), as it depended completely on how the administration handled the occupation stage. Had they have done so differently, such as retaining some baathists and administrators from the old regime, while slowly rebuilding the country, the insurgency might never have materialized to the strength as it did. This was the method applied in post 1945 Japan and many other occupied states, and it has worked quite well by provided continuity while enabling change to occur. However the government was dissolved and chaos ensued with basic infrastructure. Not many people would have predicted that the US adminstration would have taken its committment to emancipating the Iraqi people so seriously as to do this move.

Perhaps there is a good reason why the US finds it so difficult to get people on board with its "humanitarian interventions" (with Kosovo being another case where humanitarian intervention exacerbated a situation and made things worse).
Your argument parallels that made by Noam Chomsky, and is fundamentally flawed and debased from fact. First off, the Clinton Administration did not want to get involved in Kosovo, and actively rejected the idea of involvement throughout 1998, except to go with the diplomatic option. Actually out of the NATO allies, they and Greece, were the most reluctant to become involved, as it was Germany, France and the United Kingdom that wanted intervention. They were unable to carry one out because most of the military capabilities needed for such an undertaking were provided by NATO and the US. This would foster the creation of the European Union Security and Defence Policy at Portlach and St. Malo conferences, because Europe could not get involved without the US. The deteriorating situation on the ground, forced Clinton to act beyond his limited diplomatic response, but even the military campaign reflected his want to limit US involvement.
Secondly Kosovo was a problem that was going to get worse before it got better. While, it is true that Milosevic did intensify his ethnic cleansing actions after the bombing started, the mere fact he had forces deployed to the region that were able to carry out such attacks indicated to many that he was prepared carry it out in any event. The bombings was merely the excuse for him to carry out what he was planning to do all along. Milosevic had been complicit in one act of mass murder already, while under sanctions and international focus, do you think the EU was going to sit around and trust him not to do so again? This time in an area he considered as part of Serbia?
This is the paradox of preventative humanitarian intervention. You will never know if you've prevented a humanitarian catastrophe from occuring if you sucessfully intervene. Had UNAMIR prevented genoide from occurring in Rwanda in 1994, would we know how bad it could be?

His government's lack of cooperation with UN inspectors could be chalked up to any one of a million reasons, many of them more convincing than a desire to cover up a non-existant weapons program. Maybe individual officers were trying to cover up their own corrupt scams or maybe they just didn't want a bunch of foreigners with a track record of spying on behalf of a country on the brink of invading them snooping around sensitive military sites. The evidence presented would get laughed out of court.
Your comment just ignores the fact he WAS obligated to provide a clear unfettered access to his WMD facilities, which he did not. By not allowing weapons inspectors, he was failing his obligations under international law. There was no means to independantly verify his disarmament without weapons inspectors. Many different organizations, including The International Institute of Strategic Studies, put out various documents that predicted what Saddam's capability could be, most of which predicted he had a capability. This was because there was no way to know what he did have. Without inspectors, everybody were forced to rely on saddam's word, a very dodgy prospect. Even though Saddam defied predictions, there were few that knew that. He openly flaunted missiles that exceeded regulations placed on him, by wheeling out a IRBM when he was supposed to be giving access to weapons inspectors.
I don't deny that this was a weaker rationale for war, but given that it was a contravention, the UK and the US used it. The threat may have been overstated, and only localized, but it was legally an easier rationale to get passed.
