Conscientious objectors to military service are either general objectors or selective objectors. The former object to all wars; the latter object to only some wars. There is widespread popular and political support in western liberal democracies for exemptions for general objectors, but currently there is little support for exemptions for selective objectors. Many who advocate exemptions for selective objectors attempt to build upon the strength of support that is enjoyed by exemptions for general objectors. They argue that selective objectors ? (...) like general objectors ? sincerely believe that it would be deeply morally wrong for them to fight in the wars to which they object. I argue that a stronger moral case for exemptions for selective objectors relies upon a different claim: selective objections are often accurate. It is often immoral to fight in the wars to which selective objectors object. While some advocates of exemptions for selective objectors have identified accuracy as a reason for offering exemptions, they have usually not adequately distinguished sincerity from accuracy. However, keeping these two moral reasons for exemptions distinct clarifies and strengthens the moral case for exemptions for selective conscientious objectors. (shrink)

Abstract This article evaluates the ?drive toward greater autonomy? in lethally-armed unmanned systems. Following a summary of the main criticisms and challenges to lethal autonomy, both engineering and ethical, raised by opponents of this effort, the article turns toward solutions or responses that defense industries and military end users might seek to incorporate in design, testing and manufacturing to address these concerns. The way forward encompasses a two-fold testing procedure for reliability incorporating empirical, quantitative benchmarks of performance in compliance with (...) formalized and programmable rules of engagement, and a conception of ?due care? in product liability. This would be designed in analogy with procedures currently followed by well-intentioned governments and militaries with their own (human) military personnel, both to ensure against failure, and to accept responsibility and compensate victims of inadvertent and unintended accidents. The procedure is designed specifically to address objections first posed by Robert Sparrow (2007) and Noel Sharkey (2007), and echoed in P.W. Singer's critically acclaimed Wired for War (2009), that lethal autonomous systems cannot be meaningfully held accountable for commission of war crimes, and thus the development, manufacture, and deployment of such systems would constitute a violation of international law.

The conventional view of Just War thinking holds that militaries operate under “special” moral rules in war. Conventional Just War thinking establishes a principled approach to such moral exceptionalism in order to prevent arbitrary or capricious uses of military force. It relies on the notion that soldiers are instruments of the state, which is a view that has been critiqued by the Revisionist movement. The Revisionist critique rightly puts greater emphasis on the moral agency of individual soldiers: they are not (...) mere instruments of the state. Although Revisionism has something particularly important to contribute when applied to cases that are short-of-war, where an individual agent’s moral culpability plays a greater role, soldiers fighting wars are not wholly autonomous moral agents. An Institutionalist approach that responds to Revisionist criticisms is a plausible alternative to the conventional Just War account for grounding the moral exceptionalism of war. For the Institutionalist, soldiers are moral agents with state-imposed obligations whose fundamental responsibility is the performance of the proper moral ends of the military institution they serve. If this is true, then soldiers have a moral obligation to be attentive to the moral corruption of the military institution of which they are a part. (shrink)
