Responsibility for the provision of global public goods is generally couched in moral terms: terms that, to one side of the important moral argument, signal the deficit of global collective action despite recent engagements in the normative concept of “sovereignty as responsibility.” In this context the article seeks greater emphasis, in morally informed reflection on world politics, on political responsibility. The argument is made in two steps. The article considers first the specificity of moral responsibility and the inextricability of moral and political interest in international relations. Having situated both with regard to the decision-making structures of national government, the article argues, second, for a normative reconfiguration of political duty in terms of task-efficacy, republican legitimacy, and political leadership. As a result, a badly needed marriage between national priorities and global threats and challenges is made possible.
