Not strictly true MGoH:

No member state in the United Nations has relinquished it's right to act independently and take what ever action it deems necessary in its own defence.

<<"...no problem was apparent until Bush started talking about regime change.">>

The current regime in Iraq has been in power under the present leadership since 1979. It has consistantly ignored its obligations under the terms on UNSC resolutions directed at its activities. Iraq has been afforded opportunity after opportunity to comply with those resolutions - Iraq has refused to co-operate and comply on every occasion.

With that as the back-ground I would have though it no great bound of logic to link that non-co-operation to the people in power in Iraq, or, to the obvious conclusion that if the international community wants Iraq to disarm, then regime change is essential - because the guys that are there at the moment show absolutely no sign, or intention of doing so.
