Abstract: Examines which political principles should govern global politics. It explores ethical issues in justice that arise at the global level and addresses questions such as: are there universal values, and if so, what are they; what human rights, if any, are there; are there global principles of distributive justice; should there be a system of supra-state institutions; is national self-determination defensible; when, if ever, may political regimes wage war; and is humanitarian intervention justified?The book outlines and defends an egalitarian liberal brand of cosmopolitanism to address these questions, maintaining that there are universal principles, arguing that these include universal civil and political human rights, and defending the application of global principles of distributive justice. On this basis, it makes a case for a system of supra-state political institutions to promote these universal principles of justice further. Having set out principles of ideal theory, the book then examines what principles should apply when injustices are committed. To do this it examines when political regimes may wage war and when they may engage in intervention, and thereby draws on cosmopolitan principles to derive and defend a cosmopolitan conception of just war and humanitarian intervention. In arriving at these conclusions, the book engages in a sustained analysis of the competing arguments on all the above issues, examining the arguments of nationalists, realists, and those who affirm the ideal of a society of states. To do this, the book explores and integrates the work of philosophers, political theorists, and international relations scholars, and illustrates its ethical argument and theoretical analysis with empirical examples. Furthermore, it argues that the issues examined in the book cannot be adequately treated in isolation from each other but must be treated as an interlinked whole.
