Combining deep moral argument with extensive factual inquiry, Richard Miller constructs a new account of international justice. Though a critic of demanding principles of kindness toward the global poor and an advocate of special concern for compatriots, he argues for standards of responsible conduct in transnational relations that create vast unmet obligations. Governments, firms and people in developed countries, above all, the United States, by failing to live up to these responsibilities, take advantage of people in developing countries. Miller's proposed standards of responsible conduct offer answers to such questions as: What must be done to avoid exploitation in transnational manufacturing? What framework for world trade and investment would be fair? What duties do we have to limit global warming? What responsibilities to help meet basic needs arise when foreign powers steer the course of development? What obligations are created by uses of violence to sustain American global power? Globalizing Justice provides new philosophical foundations for political responsibility, a unified agenda of policies for responding to major global problems, a distinctive appraisal of 'the American empire', and realistic strategies for a global social movement that helps to move humanity toward genuine global cooperation.
