Because the poorest people tend to die from easily preventable diseases, addressing poverty is a relatively cheap way to save lives. War, by contrast, is extremely expensive. This article argues that, since states that wage war could alleviate poverty instead, poverty can render war unjust. Two just war theory conditions prove relevant: proportionality and last resort. Proportionality requires that war does not yield excessive costs in relation to the benefits. Standardly, just war theorists count only the direct costs: the death (...) and destruction wrought by war. This article argues that it can sometimes be appropriate to add the opportunity costs of a failure to alleviate poverty. Last resort is the condition that there must be no better alternative means of achieving the same just end for which the war is waged. This article argues that there are some cases in which alleviating poverty may constitute a better alternative. These are cases in which the most fitting description of the just end for war is sufficiently general that poverty alleviation offers a means to pursue it. The idea that poverty can sometimes render war unjust has, to date, been largely overlooked. It is, nevertheless, an idea with profound implications since, once taken seriously, war becomes much harder to justify. Wars that, in every other respect, seem just may prove disproportionate or unnecessary given the alternative of alleviating poverty. (shrink)

According to Thomas Pogge, rich people do not simply violate a positive duty of assistance to help the global poor; rather, they violate a negative duty not to harm them. They do so by imposing an unjust global economic structure on poor people. Assuming that these claims are correct, it follows that, ceteris paribus, wars waged by the poor against the rich to resist this imposition are morally equivalent to wars waged in self-defense against military aggression. Hence, if self-defense against (...) military aggression is just, then, ceteris paribus, so are defensive wars against the imposition of economic injustice. While I do not think Pogge’s analysis of the causes of global poverty is correct, I defend these inferences against various challenges. (shrink)

Can the global poor wage a just redistributive war against the global rich? The moral norms governing the use of force are usually considered to be very strict. Nonetheless, some philosophers have recently argued that violating duties of global justicecanbe a just cause for war. This paper discusses redistributive wars. It shows that the strength of these arguments is contingent on the underlying account of global distributive justice. The paper focuses on the “doing harm argument,” under the assumption that the (...) alternative “allowing harm argument” is a more difficult route to justify redistributive wars. After highlighting several preliminary problems, the paper breaks down and assesses in depth the “doing harm argument”: the empirical premise, the rights violation that constitutes the wrong, liability and degrees of responsibility, and the conditions for justified self-defense. By drawing on principles reflected in criminal law, this paper argues that a general “doing harm argument” for redistributive wars is unconvincing, while a reinterpretation of that argument could theoretically give rise to a just cause for war.

Despite the popularity of arming rebels as a foreign policy option, there is very little, if any, detailed engagement with the ethical issues surrounding the practice. There is a growing literature on the ethical issues surrounding civil wars and, more specifically, the conditions for engaging in just rebellion; but the focus of this literature is largely on the question of the justifiability of the rebels themselves in engaging in civil war and their conduct when doing so, rather than the permissibility (...) of the arming of rebels by other agents. It is precisely this issue that I want to address here. Overall, I argue that the process should be generally eschewed. More specifically, this article seeks to establish that arming rebels is generally impermissible and only exceptionally morally permissible. The former, far more restrictive claim will be established in the first part of the article. The latter, more permissive claim will be established in the second part of the article. (shrink)
