Many political theorists today deny that citizenship can be defended on liberal grounds alone. Cosmopolitans claim that loyalty to a particular state is incompatible with universal liberal principles, which hold that we have equal duties of justice to persons everywhere, while nationalist theorists justify civic obligations only by reaching beyond liberal principles and invoking the importance of national culture. In "Liberal Loyalty," Anna Stilz challenges both views by defending a distinctively liberal understanding of citizenship.

Drawing on Kant, Rousseau, and Habermas, Stilz argues that we owe civic obligations to the state if it is sufficiently just, and that constitutionally enshrined principles of justice in themselves--rather than territory, common language, or shared culture--are grounds for obedience to our particular state and for democratic solidarity with our fellow citizens. She demonstrates that specifying what freedom and equality mean among a particular people requires their democratic participation together as a group. Justice, therefore, depends on the authority of the democratic state because there is no way equal freedom can be defined or guaranteed without it. Yet, as Stilz shows, this does not mean that each of us should entertain some vague loyalty to democracy in general. Citizens are politically obligated to their own state and to each other, because within their particular democracy they define and ultimately guarantee their own civil rights.

"Liberal Loyalty" is a persuasive defense of citizenship on purely liberal grounds.

Territorial Sovereignty: A Philosophical Exploration offers a qualified defense of a territorial states-system. It argues that three core values-occupancy, basic justice, and collective self-determination-are served by an international system made up of self-governing, spatially defined political units. The defense is qualified because the book does not actually justify all the sovereignty rights states currently claim, and that are recognized in international law. Instead, the book proposes important changes to states' sovereign prerogatives, particularly with respect to internal autonomy for political minorities, immigration, and natural resources. Part I of the book argues for a right of occupancy, holding that a legitimate function of the international system is to specify and protect people's preinstitutional claims to specific geographical places. Part II turns to the question of how a state might acquire legitimate jurisdiction over a population of occupants. It argues that the state will have a right to rule a population and its territory if it satisfies conditions of basic justice and also facilitates its people's collective self-determination. Finally, Parts III and IV of this book argue that the exclusionary sovereignty rights to control over borders and natural resources that can plausibly be justified on the basis of the three core values are more limited than has traditionally been thought. Oxford Political Theory presents the best new work in contemporary political theory. It is intended to be broad in scope, including original contributions to political philosophy, and also work in applied political theory. The series will contain works of outstanding quality with no restriction as to approach or subject matter. Series Editors: Will Kymlicka and David Miller.

Leif Wenar's 2016 book Blood Oil: Tyrants, Violence, and the Rules that Run the World argues that much of the conflict, suffering, and injustice in the world is driven by an archaic rule in global trade that forces consumers to fund oppression and corruption. This oil curse is a major threat to global peace and stability. Wenar sets out Clean Trade policies to lift the oil curse through national legislation that affirms democratic principles. In Beyond Blood Oil, Wenar summarizes and extends his views, setting the stage for five essays from first-class critics from the fields of political theory, philosophy, and energy politics. Wenar replies vigorously and frankly to the critics, making the volume the scene of a highly energetic debate that will benefit all scholars, students, and global citizens interested in global justice, international security, oil politics, fair trade, climate change, and progressive reforms.
