Are There Moral Limits to Military Deception?

It is widely agreed that deception of the enemy can be morally permissible in war. However, the question of the morally acceptable limits to deception in war has barely been explored in contemporary ethics. This paper defends the thesis that there are no moral limits on military deception per se, that is, no limits based on the ethics of truthfulness. Rather, all moral restriction against deception in war is based on another moral principle: military deception is morally unacceptable only when it violates the principle of not harming those who do not intend to harm us.
