The ethical Principle of Proportionality requires combatants not to cause collateral harm excessive in comparison to the anticipated military advantage of an attack. This principle is considered a major (and perhaps insurmountable) obstacle to ethical use of autonomous weapon systems (AWS). This article reviews three possible solutions to the problem of achieving Proportionality compliance in AWS. In doing so, I describe and discuss the three components Proportionality judgments, namely collateral damage estimation, assessment of anticipated military advantage, and judgment of “excessiveness”. (...) Some possible approaches to Proportionality compliance are then presented, such as restricting AWS operations to environments lacking civilian presence, using AWS in targeted strikes in which proportionality judgments are pre-made by human commanders, and a ‘price tag’ approach of pre-assigning acceptable collateral damage values to military hardware in conventional attritional warfare. The article argues that application of these three compliance methods would result in AWS’ achieving acceptable Proportionality compliance levels in many combat environments and scenarios, allowing AWS to perform most key tasks in conventional warfare.

In his recent JME article Daniel Restrepo argues that both legal and ethical rules should protect the so-called Naked Soldiers, combatants engaged in activity unrelated to military operations and unaware of the imminent danger threatening them. I criticize this position from several angles. I deny the existence of any link between vulnerability and innocence, and claim ignorance of deadly threats does not give rise to a morally distinguished type of vulnerability. I argue that actions not contributing to the war effort (...) are nevertheless an inherent part of fighting a war, and that combatants do not signal intention to abandon their commitment to the war effort by undertaking these. I show that by granting hors de combat status to Naked Soldiers, we would unjustly disadvantage their opponents and engender significant and manifold practical difficulties that the proponents of the view fail to solve or even anticipate. Finally, I demonstrate that Restrepo’s general project of “making killing in war difficult to legitimately justify” regardless of why, how and by whom the killing is done is incompatible with just war theory’s basic assumptions. That project is in fact pacifist in nature and as such redundant in light of pacifism’s broader and stronger implications. (shrink)

The Laws of Armed Conflict require that war crimes be attributed to individuals who can be held responsible and be punished. Yet assigning responsibility for the actions of Lethal Autonomous Weapon...

Just War Theory debates discussing the principle of the Moral Equality of Combatants involve the notion of Invincible Ignorance; the claim that warfi ghters are morally excused for participating in an unjust war because of their epistemic limitations. Conditions of military deployment may indeed lead to genuinely insurmountable epistemic limitations. In other cases, these may be overcome. This paper provides a preliminary sketch of heuristics designed to allow a combatant to judge whether or not his war is just. It delineates (...) the sets of relevant facts uncontroversially accessible and inaccessible to contemporary professional soldiers. Relevant facts outside these two sets should by default be treated as inaccessible until proven otherwise. Even such a rudimentary heuristic created in this way demonstrates that practical recommendations of MEC-renouncing Just War Theory are not too challenging to follow and still signifi cantly impact a compliant combatant’s behavior.

Efforts to ban Autonomous Weapon Systems were both unsuccessful and controversial. Simultaneously the need to address the detrimental aspects of AWS development and proliferation continues to grow in scope and urgency. The article presents several regulatory solutions capable of addressing the issue while simultaneously respecting the requirements of military necessity and so attracting a broad consensus. Two much stricter solutions – regional AWS bans and adoption of a no first use policy – are also presented as fallback strategies in case (...) achieving AWS’ compliance with the Laws of Armed Conflict proved elusive. Together, the solutions presented form an outline of a flexible regulatory strategy able to adjust to different technological outcomes and providing a sensible compromise to solve the current deadlock on the AWS issue.

Arguments from human dignity feature prominently in the Lethal Autonomous Weapons moral feasibility debate, even though their exists considerable controversy over their role and soundness and the notion of dignity remains under-defined. Drawing on the work of Dieter Birnbacher, I fix the sub-discourse as referring to the essential value of human persons in general, and to postulated moral rights of combatants not covered within the existing paradigm of the International Humanitarian Law in particular. I then review and critique dignity-based arguments (...) against LAWS: argument from faulty targeting process, argument from objectification, argument from underappreciation of the value of human life and the argument from the absence of mercy. I conclude that the argument from the absence of mercy is the only dignity-based argument that is both valid and irreducible to another class of arguments within the debate, and that it offers insufficient justification for a global ban on LAWS.

In this article I consider a certain characteristic of our times as a “secular age,” namely, a series of complications in our understanding of transgression. Transgression implies the presence of some rules and laws which can be violated. As long as the rules and laws are perceived as right, as a way of protecting the values which would otherwise perish, transgression appears to be a wrong thing to do, a misdeed, a criminal act. Needless to say, the very conceptual structure (...) makes sense only provided that the distinctions between right and wrong, good and evil, lawful and lawless are not arbitrary, which, in turn, depends on the presence of the concept of truth. In the secular age, though, the concept of truth becomes not only difficult to handle, since it is incompatible with the modern frame of mind, but also assumes some derogatory connotations, up to the point when to insist on the distinction between (truly) right and (truly) wrong is in itself a wrong thing to do. That is the state of contemporary societies which G. K. Chesterton examines in his work Heretics. The effect of Chesterton’s reflections is a new map of right/wrong, good/evil, lawless/lawful permutations. After Chesterton, I comment on the character of a new heretic, one for whom transgression, understood as the attack on buried-for-long orthodoxy, is too easy a thing to do. To illustrate the mentioned changes of perspective, I refer to an exemplary criminal figure of the West, that is, the biblical serpent, and its criticism. (shrink)
