“Coalition of the willing” is a phrase that we hear invoked with frequency in world politics. Significantly, it is generally accompanied by claims to moral responsibility. Yet the label commonly used to connote a temporary, purpose-driven, self-selected collection of states sits uneasily alongside these assertions of moral responsibility.

This article explores how the informal nature of such associations should inform judgments of moral responsibility. I begin by briefly recounting what I call a model of institutional moral agency in order to explain why it seems theoretically and practically problematic to talk about the moral responsibilities of informal associations. I then focus on coalitions of the willing as prominent, and challenging, examples of such associations, before raising misgivings about my own rather stark distinction if it means that accounts of moral responsibility must be reduced to the members—or potential members—of such coalitions in a way that neglects the moral significance of their acting together. Prompted by these concerns, I explore arguments by Virginia Held and Larry May about moral responsibility in relation to informal associations and identify insights that can be taken from these positions to refine our expectations and evaluations of the actions associated with such collectivities. Finally, I consider the particular implications of these insights in relation to the widely espoused duty to intervene to rescue vulnerable populations.

As of 2007 the world economy has been caught in the worst crisis since the 1930s. Yet after two years of only partly successful efforts to mobilize and coordinate global action of financial control and stimulus, ending with the G-20 meeting of March 2009, responsibility for corrective economic initiatives has essentially been left to individual countries, supported by the International Monetary Fund (IMF) and the European Union (EU). Moreover, such support has been usually conditional on countries following financial policies of tough austerity. The United States took some actions to stimulate its economy, but by many accounts these were insufficient. Most of Europe has not even attempted stimulus measures and has been in a period of economic stagnation, with falling real incomes among the poorest parts of the population. Although some signs of “recovery” have been heralded in 2013 and 2014, growth has mostly been measured from a lower base. There is little evidence of broad-based economic recovery, let alone improvements in the situation of the poor or even of the middle-income groups.
