After World War II the Nurenberg trials and the conventions that arose out of them codified the idea that there are right and wrong ways to wage war. That prisoners of war have definite rights, and that non-combatants should be treated differently than soldiers. Some think the idea of a morality of warfare makes no sense, and that the distinction between soldiers and non-combatants is meaningless in the setting of modern warfare. John and Ken discuss these issues in the light of philosophical theories of right and wrong.
