I would guess, I would surmise that some of the more spectacular bombings are done by al Qaeda suiciders.
Trying to stop suiciders -- which we're doing a pretty good job of on occasion -- is difficult to do. And what the Iraqis are going to have to eventually do is convince those who are conducting suiciders who are not inspired by Al Qaeda, for example, to realize there's a peaceful tomorrow.
Nobody's ever suggested that the attacks of September the 11th were ordered by Iraq. I have suggested, however, that resentment and the lack of hope create the breeding grounds for terrorists who are willing to use suiciders to kill, to achieve an objective. I have made that case.
