Has it? Civilian casualties are inevitable these days in a war. Sherman's maxim rings truer than ever, and it's one reason that wars need a damned good reason to start in the first place. Starting one for shits and giggles the way Bush did with Iraq is by the converse *un*forgivable for just that reason. Modern firepower is too deadly to be used in senseless wars. By the same token, it's something that applies to *all* combatants be they state or non-state. Ordinarily I loathe Curtis LeMay but he was right when he said all war is immoral.
