War not only has its own weapons, it has its own ethic, its own standard of right and wrong. ...Do whatever is necessary to win. This fact was emphasized in a recent statement by Winston S. Churchill, former first lord of the British admiralty: "When all is over, torture and cannibalism were the only two expedients that the civilized, scientific, Christian states had been able to deny themselves: and these were of doubtful utility."
