In post-9/11 world, we can't stand idly by while third-world politicians take bribes and kickbacks!
Not when they are preventing a full accounting of what a certain regime had in the way of WMDs. A regime that for over a decade had failed to account for what it had done with its weapons systems, a responsibility which it agreed to when hostilities ceased at the end of the original Gulf War. Not when they have a vested interest in keeping that regime in power, a regime which had made it abundantly clear that it had no problem with using WMDs which it developed or procured.

It's no surprise that original quote comes from a man who hasn't had to make a professional decision based upon imperfect information in his life. Far easier to kick back and second guess politicians he doesn't like.
