A just soldier's dilemma: facing a war that does not meet jus ad bellum criteria

In our challenging times individuals in military services may find themselves in the position of being called to contribute to a war whose overall justice they personally find morally suspect, or about which they have moral qualms. The right course of action in this situation can be a serious dilemma. Applying the principle of double effect to this dilemma recognizes essential state responsibility for war, but does not discount the soldier's personal moral responsibilities or individual will. This novel application of the principle of double effect treats damage produced by participating in a questionable war as a side-effect of pursuing other—clearly justifiable—intentions. The just war tradition already uses the principle of double effect when weighing the permissibility of individuals' acts in war, such as choosing bombing targets. The proposal here is to evaluate the decision to contribute to the war effort at all. This adaptation of the classic just war principle of double effect can be used to justify some—but not all—individual participation when a war's state-level justification is suspect.
