I think the interesting question is whether, as Christopher Caldwell thinks, the War in Vietnam is seen as evil by almost everybody. It is logical to think that it is, if the acts which it required are evil in everyone's sight, but people are not very logical. Hence the support for the war in Yugoslavia by people who should have known better, out of which the Novi Sad incident and other like it inevitably sprang. The focus on unusual individual acts allows the policies of war to go forward unhindered; that is why most of Congress voted for the War in Colombia, just as they voted for the War in Yugoslavia and the War in Vietnam. The connection between war and atrocity is blanked out.
