As Teribus pointed out "the original draft of 1441, clearly stated that unless Iraq co-operated fully and pro-actively with UNSCOM, military action would result."

And it was amended so as to remove that part, with automatic military action being replaced by "serious consequences" - and the reason members insisted on that amendment was precisely because they did not intend this resolution to authorise military action. "Serious consequences" meant that it was up to the Security Council to determine the nature of these consequences, and the timetable for imposing them.

That was the unanimous decuision of 1441 - and that was the decision which was unilaterally overturned by the USA, with the UK falling into line.
