Abstract
In some cases, the U.S. should adopt a policy of assassinating national leaders. On just war theory, national leaders are sometimes combatants. This is because some leaders are both causal and logical agents of an unjust military campaign. Such leaders occupy this logical role because in some cases their position has an essential link to their nation’s military projects. In addition, such a policy aligns with some of the policies that motivate just war theory in that assassination does not target innocent persons, is connected to self-defense, and does not violate any international agreements. Just war theory should probably be rejected, however, since it rests on dubious claims about the non-contractual essentialist conditions of combatant. On a self-defense theory, some national leaders may be killed because they are threats. They are threats because they originate a causal process that will likely bring about large amounts of unjust harm. In so doing, they forfeit those moral rights that protect them against injurious action and thus remove one of the major constraints against violence and killing. On a consequentialist theory, such a policy would likely bring about the best consequences since it would be a vital tool in the protection against genocide, unjust military aggression, and other horrendous state actions that have characterized the twentieth century. It is unlikely that the harm that would result from such a policy (e.g., its misuse) would outweigh the expected gain from it.
