The nation-state has long been under attack from liberal economists and cosmopolitan ethicists alike. But it has proved remarkably resilient and remains the principal locus of governance as well as the primary determinant of personal attachments and identity. The global financial crisis has further under- scored its centrality. Against the background of the globalization revolution, the tendency is to view the nation-state as a hindrance to the achievement of desirable economic and social outcomes. Yet it remains indispensable to the achievement of those goals.
Actually, we all do.
