This article offers both a critique and reconstruction of cosmopolitan democracy. It argues that cosmopolitan democracy promotes an excessively individualist account of political life and a functionalist approach to political community that are likely to undermine the kinds of national communities and citizens that are most likely to mobilise against global injustices. It argues that the alleviation of global injustices depends on the rescuing and reframing, rather than weakening, of national identities so that they take on a more cosmopolitan character. Cosmopolitan democracy is dependent upon cosmopolitan nationalism, based on a commitment to common liberty and justice at home and abroad.
