When has there been an ethical war? Not if the art of war can have ethics in conduct, but where the war itself was a just one. The only just wars are revolutionary ones, if any. Except revolution today, like the Arab Spring, isn't done in a formal war. Hell, no real revolution is done like that - even the American Revolution was predominantly guerilla tactics. The wars that obey codified ethics are always the formal wars that were started for purely unethical reasons.
