Oh, so you are saying that the US didn't try to take the UN into confidence? We spent a lot of time there, we got resolution 1441 passed. Unfortunately, France was opposed to tougher measures and inspections. Without the direct threat of force, it is impossible to make Saddam actually disarm. So unfortunately, France would be the reason for the absolute failure of the UN.
And by the way, are you referring to the same innocent people that have toiled under Saddam's oppressive rule for 20 years? Iraq is such a rich nation full of such rich oil resources. Compare Kuwait with Iraq. Kuwait is less rich than Iraq in terms of oil, but you can see the development and progress they have been made, even under the constant threat of WMD from Saddam. Even Kuwait's people are prosperous. Compare them to the Iraqi people, who should have been living in one of the most developed Middle-East nation if Saddam wasn't there.
