That one man happened to be the secretary general of the UN, but i guess you didn't read the whole thing, did you?
I'll pick out some quotes, let me know if you want any of them explained in simple english:
the decision to take action in Iraq should have been made by the Security Council, not unilaterally.
there should have been a second UN resolution following Iraq's failure to comply over weapons inspections.
When pressed on whether he viewed the invasion of Iraq as illegal, he said: "Yes, if you wish. I have indicated it was not in conformity with the UN charter from our point of view, from the charter point of view, it was illegal."
I really dont want to bother discussing an issue that is already closed. You're trying to argue that black is white.
