International law and conventional morality grant that states may stand ready to defend their borders with lethal force. But what grounds the permission to kill for the sake of political sovereignty and territorial integrity? In this book leading theorists address this vexed issue, and set the terms of future debate over national defence.

Should governments give special rights to ethnic and cultural minorities? Should rich countries open their borders to economic immigrants or transfer resources to poor countries? When framing and implementing economic and environmental policies, should current generations take into account the interests of future generations? If our political community committed a wrong against another group a hundred years ago, do we owe reparations to current members of that group? These are just some of the pressing questions which are fully explored in (...) this accessible new analysis of justice in the contemporary world. They force us to reconsider the extent of our obligations to our fellow citizens, future generations and foreigners. Justice in a Changing World introduces the moral debates around issues such as immigration, national self-determination, cultural rights and reparations, as well as resource transfers from one generation to the next and from rich to poor countries, through the lenses of liberalism, communitarianism and libertarianism. In so doing, it helps to unravel the complexity of key ethical dilemmas facing us today. The book will be a valuable resource for students of political theory, and will appeal to anyone wishing to reflect on their deepest values and commitments by putting them to the test of practical politics.
