A few months ago, I found a Web site loaded with pictures and videos from Iraq, the sort that usually aren't seen on the news. I watched insurgent snipers shoot American soldiers and car bombs disintegrate markets, accompanied by tinny music and loud, rhythmic chanting, the soundtrack of the propaganda campaigns. Video cameras focused on empty stretches of road, building anticipation. Humvees rolled into view and the explosions brought mushroom clouds of dirt and smoke and chunks of metal spinning through the air. Other videos and pictures showed insurgents shot dead while planting roadside bombs or killed in firefights and the remains of suicide bombers, people how they're not meant to be seen, no longer whole. The images sickened me, but their familiarity pulled me in, giving comfort, and I couldn't stop. I clicked through more frames, hungry for it. This must be what a shot of dope feels like after a long stretch of sobriety. Soothing and nauseating and colored by everything that has come before. My body tingled and my stomach ached, hollow. I stood on weak legs and walked into the kitchen to make dinner. I sliced half an onion before putting the knife down and watching slight tremors run through my hand. The shakiness lingered. I drank a beer. And as I leaned against this kitchen counter, in this house, in America, my life felt very foreign.
