Morality is about balancing the consequences of your actions. All the consequences.

In the case of this war it was about what was likely to happen in Iraq; and what was going to be the consequences of tearing up international agreements that had been painnfully put together for good reasons; and what the consequences would be in this "war on terror".

It seems to me that pretty well everything which has been done has played into the hands of Al Qaida. Bin Laden might just as well have been sitting in the Oval Office, playing chess, and willingly sacrificing expendable pieces.
