An-My Lê was a refugee, but she never really escaped the Vietnam War. She stands by the sidelines and photographs men who reenact battles from Vietnam in the forests of Virginia. She haunts an American military base where soldiers prepare to set out for Iraq and Afghanistan. Only the lead-up and the look back are in the frame. The real wars are left to the imagination.
