Abstract
This essay explores several moral attitudes that undergird a commitment to humanitarian intervention. Humanitarian intervention is usually understood to mean assistance or relief, often in the form of a rescue response by the international community to such emergencies as natural disasters, systematic human rights violations, or genocides that take place within the borders of sovereign states. But the term can equally mean aid before the fact, or prevention, as well as longer-term commitments to international justice that go beyond emergency relief. Whether the aid is relief or prevention, short- or long-term, and however it relates to broader questions of international justice, the same question applies: How do we come to feel the ethical imperative to ally ourselves with those outside our borders? If, as Kant puts it, “ought implies can,” then what makes the “oughts” of intervention psychologically feasible? Of course in international affairs the issue is, more typically, whether certain proposed interventions are politically feasible, Do they promote our national interest? Are they cost effective? Even more practically, will food relief get where it is intended to go? Do the rules of military engagement allow us to protect the victims we are trying to help?
