>>But that doesn't change the fact that the initial action was justified....
Lets not forget that the invasion was justified by WMD, not because Saddam was naughty. Which was why people like the French refused to take part - because they knew there were no WMD. Sure it's easy to list lots of reasons Saddam was a naughty man- but if that's a reason to invade then most of the 3rd World should be invaded by now and places like Libya should be American protectorates.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
