Michael Walzer is one of the world's most eminent philosophers on the subject of war and ethics. Now, for the first time since his classic "Just and Unjust Wars" was published almost three decades ago, this volume brings together his most provocative arguments about contemporary military conflicts and the ethical issues they raise.The essays in the book are divided into three sections. The first deals with issues such as humanitarian intervention, emergency ethics, and terrorism. The second consists of Walzer's responses to particular wars, including the first Gulf War, Kosovo, Afghanistan, and Iraq. And the third presents an essay in which Walzer imagines a future in which war might play a less significant part in our lives. In his introduction, Walzer reveals how his thinking has changed over time.Written during a period of intense debate over the proper use of armed force, this book gets to the heart of difficult problems and argues persuasively for a moral perspective on war.
