"War has its own laws and one of the oldest and most persistent is that those who have surrendered and civilians, where possible, should be spared. Yet we all know the stories or have seen pictures of the sacking of cities, the execution of prisoners of war, the shelling of churches filled with refugees, or the farm buildings deliberately set on fire, and we remember names such as Oradour or Wounded Knee or Nanjing. For any American who lived through the Vietnam War the incident at My Lai, when a representative group of ordinary American soldiers rampaged through a village, has come to represent the barbarism of much of that war. (The Vietnamese forces committed their own atrocities, but Vietnam has been slow to come to terms with them.) In 1968 American reporters in the country started to hear stories about the murder in cold blood of some 500 villagers, of all ages, by an American patrol. One courageous helicopter pilot who was there did his best to save the Vietnamese and later filed a report with his superiors, who did nothing."
