I'm not pro-war. But I think war has been the dominant condition of humankind, and peace has been the anomaly - certainly sustained periods of peace that profit great masses of people - and I think war has worked, even awful hellish wars: worked to staunch fascist aggression in Europe, worked to preserve the Union after secession in the United States, etc. Not always, maybe not often, but to say never is to reject history in favor of a wishful unreality.
