Something to think about as our Commander-in-chief who, having just accepted the Nobel Peace Prize, is escalating the war effort in Afghanistan:
This lust of sovereignty disturbs and consumes the human race with frightful ills. By this lust Rome was overcome when she triumphed over Alba, and praising her own crime, called it glory. For, as our Scriptures say, "the wicked boasteth of his heart's desire, and blesseth the covetous, whom the Lord abhorreth" [Psalm 10:3]. Away, then, with these deceitful masks, these deluding whitewashes, that things may be truthfully seen and scrutinized. Let no man tell me that this and the other was a "great" man, because he fought and conquered so and so. Gladiators fight and conquer, and this barbarism has its meed of praise; but I think it were better to take the consequences of any sloth, than to seek the glory won by such arms.
(City of God, book 3, n. 14)
