Killing bin Laden: An Ethical Analysis is a short treatise on the possible ethical justification for the U.S. mission to kill Osama bin Laden. After rejecting the standard justifications most commonly used in support of the killing, Strawser ultimately argues that the killing was ethically permissible as an act of defensive harm on behalf of innocents. The book contends bin Laden was morally responsible for a collection of unjust threats such that he was liable to be killed. Moreover, the many unique features of the bin Laden case -such as the use of pre-emptive harm and the collective agency of al-Qaeda - do not defeat that liability. The monograph also includes discussions of the apparent violation of Pakistan's sovereignty and the morally dubious celebrations of bin Laden's death, among other morally relevant issues.
