ABSTRACTThe aim of this paper is to draw attention to an issue which has been largely overlooked in contemporary just war theory – namely the impact that the conditions under which an army is assembled are liable to have on the judgments that are made with respect to traditional principles of jus ad bellum and jus in bello. I argue that the way in which an army is assembled can significantly alter judgments regarding the justice of a war. In doing (...) so, I present and defend a principle of ‘just assembly’ and argue that satisfying this principle is an essential part of any deliberation regarding the justice of a particular conflict.

If the resources used to wage wars could be spent elsewhere and save more lives, does this mean that wars are unjustified? This article considers this question, which has been largely overlooked by Just War Theorists and pacifists. It focuses on whether the opportunity costs of war lead to a form of pacifism, which it calls ‘Opportunity Costs Pacifism’. The article argues that Opportunity Costs Pacifism is, at the more ideal level, compelling. It suggests that the only plausible response to (...) Opportunity Costs Pacifism applies in highly nonideal circumstances. This has major implications for Just War Theory and pacifism since it is only at the highly nonideal level that war can be justified. (shrink)

Many think that it would be wrong to defend an individual from attack if he competently and explicitly refuses defensive intervention. In this paper, I consider the extent to which the preferences of victims affect the permissibility of defending groups or aggregates. These cases are interesting and difficult because there is no straightforward sense in which a group can univocally consent to or refuse defensive intervention in the same way that an individual can. Among those who have considered this question, (...) the dominant view is that that consent imposes only an extremely weak constraint on defending groups. I argue that this is mistaken and defend a much more robust requirement. Indeed, on the account that I develop there are cases in which the refusal of a single member of a victim is enough to make it impermissible to defend a much larger group. At the heart of my account is the idea that consent functions as an internal component of the broader requirement that defensive harms be proportionate: if a victim validly refuses defensive intervention, the fact that defence will benefit him cannot be used to justify harming innocents as the lesser-evil. An important implication of this view is that what constitutes sufficient consent from the members of a victim group will vary on a case-by-case basis. (shrink)

The International Commission on Intervention and State Sovereignty's report, The Responsibility to Protect, argues that when a state is unable or unwilling to uphold its citizens? basic human rights, such as in cases of genocide, ethnic cleansing, and crimes against humanity, the international community has a responsibility to protect these citizens by undertaking humanitarian intervention. An essential issue, however, remains unresolved: which particular agent in the international community has the duty to intervene? In this article, I critically examine four ways (...) of assigning this duty. Although I highlight the benefits of institutionalising the responsibility to protect, I argue that we should adopt, in the short term at least, a consequentialist solution: humanitarian intervention should be the responsibility of the intervener that will be the most effective.
