Humanitarian Intervention: An Overview of the Ethical Issues

The capacity to focus on the issue of humanitarian intervention represents what Joel Rosenthal has noted as the maturation of the field of ethics and international affairs. If nothing else, the debate surrounding this vexed issue has demonstrated that we have left behind the so-called oxymoron problem: there is no reason now to be defensive about bracketing the terms “ethics” and “international relations.” One can hardly talk about Bosnia, Rwanda, Haiti, Somalia, or any cases of possible outside intervention, without recognizing from the very beginning that ethical dilemmas abound in the way we define our goals, our interests, and the means we use to pursue them. Even Samuel P. Huntington, not usually known to be a moralist, has asserted that “it is morally unjustifiable and politically indefensible that members of the [U.S.] armed forces should be killed to prevent Somalis from killing one another.” Whether or not one agrees with that assertion (I do not), one may note that Huntington speaks in terms of moral justification and regards his view of morality to be, in effect, self-evidently true. Thus even archrealists invoke morality in urging their preferred policies. The discussion in this essay proceeds in three unequal stages. First, I present a brief and oversimple sketch of the objective and subjective changes in the broader milieu of international relations as they relate to humanitarian intervention. Second, and more substantially, I survey and analyze the arguments justifying or opposing the notion of humanitarian intervention from realist and liberal perspectives. Finally, I offer the beginnings of my own argument and consider the enormous difficulties of undertaking humanitarian intervention with any degree of effectiveness and consistency.
