Looking from the losers' side generally never gives a good impression why the winners chose that course of action and not another.

Dead iraqis? It dont see why democratic us should be bothered by that. They have killed much more and each time live better.
They lost a few and those few were allowed to lead individual experiences (torture, rape, murder...) totally legally and even being rewarded for. In their country they would have punished for that. Hence an increase of liberties for those who risk their lifes in iraq.

Angered arabs? They have no control on the democratic us political system and they dont vote.Actually they might well serve as dead meat to increase the liberties range of the democratic us people.

How many billions harvested? 5,000 billions of oil stock in a critical situation (easy to collect oil becoming less frequent)
and so on...

The president did a good job.
