"Nigel Dower has written a clear and thorough new guide to the crucial ethical questions of war and peace, nationalism and cosmopolitanism, and realism and idealism about the world we live in. His book is lively, learned, and engaged, and will be the perfect starting-point for all those wanting to think harder about these vital topical issues, whether they are students, academics, activists, or just concerned citizens."Tim Chappell, Open University "The Ethics of War and Peace provides a clear and comprehensive guide to perspectives on morality and the use of force. Analysing the 'conditions of peace' as well as the ethics of war, it offers a powerful defence of 'cosmopolitan pacificism'. This is a distinctive addition to the literature that can be warmly recommended to students of ethics and world politics."Andrew Linklater, Aberystwyth University
