So far as it goes, the distinction between an atrocity and an act of war is valid. An atrocity means an act of terrorism which has no genuine military purpose. One must accept such distinctions if one accepts war at all, which in practice everyone does. Nevertheless, a world in which it is wrong to murder an individual civilian and right to drop a thousand tons of high explosive on a residential area does sometimes make me wonder whether this earth of ours is not a loony bin made use of by some other planet.
