On the ethics of war the Quran and the New Testament are worlds apart. Whereas Jesus tells us to turn the other cheek, the Quran tells us, 'Whoso commits aggression against you, do you commit aggression against him' (2:194). The New Testament says nothing about how to wage war. The Quran, by contrast, is filled with just-war precepts. Here war is allowed in self-defense (2:190; 22:39), but hell is the punishment for killing other Muslims (4:93), and the execution of prisoners of war is explicitly condemned (47:4). Whether in the abstract is is better to rely on a scripture that regulates war or a scripture that hopes war away is an open question, but no Muslim-majority country has yet dropped an atomic bomb in war.
