As I watch the catastrophe that has befallen Iraq, it now seems absurd to cheaply suggest that it built toward any greater purpose, or paved the way for greater peace and prosperity, or that it is anything more than a net increase in the suffering and horror of a world awash in blood, or that there is even a realistic prospect for any kind of justice, some kind of restitution or payment or balancing out, even in a small way, for what has been erased.
