I really do wonder what it takes to support your own unwarranted arrogance when it confronts a reality completely at odds with it. I doubt I'm alone in having occasional nontrivial anxiety bouts over some fairly screwup early in life which had relatively trivial consequences for me or those around me. I honestly can't imagine living with the responsibility for what goes on in Iraq day after day without either having some severe psychotic break or simply curling up under the bed in the fetal position.
These people are wired up differently than me.
