Killing a person is in general among the most seriously wrongful forms of action, yet most of us accept that it can be permissible to kill people on a large scale in war. Does morality become more permissive in a state of war? Jeff McMahan argues that conditions in war make no difference to what morality permits and the justifications for killing people are the same in war as they are in other contexts, such as individual self-defence. This view is radically at odds with the traditional theory of the just war and has implications that challenge common sense views. McMahan argues, for example, that it is wrong to fight in a war that is unjust because it lacks a just cause.

Catholic pacifists blame the just war tradition of their Church. That tradition, they say, can be invoked to justify any war, and so it must be jettisoned. This book argues that the problem is not the just war tradition but the unjust war tradition. Ambitious rulers start wars that cannot be justified, and yet warriors continue to fight them. The problem is the belief that warriors do not hold any responsibility for judging the justice of the wars they are ordered to fight. However unjust, a command renders any war “just” for the obedient warrior. This book argues that selective conscientious objection, the right and duty to refuse to fight unjust wars, is the solution. Strengthening the just war tradition depends on a heightened role for the personal conscience of the warrior. That in turn depends on a heightened role for the Church in forming and supporting consciences and judging the justice of particular wars. As Saint Augustine wrote, “The wise man will wage just wars. . . . For, unless the wars were just, he would not have to wage them, and in such circumstances he would not be involved in war at all.”

Can a war really be considered justÓ? If so, which wars, and under what circumstances? If not, why not? When War is Unjust provides a systematic exploration of these questions for students of ethics, Christian doctrine, and history. For centuries the just war tradition has been the dominant framework for Christian thinking about organized conflict. This tradition sets a number of specific conditions which must be satisfied before a particular war can termed justÓ and therefore supportable by the faithful Christians. John Howard Yoder, himself a pacifist, approaches the just war theory on its own terms. His purpose: to introduce the student to this just-war tradition, and to offer a critical framework for evaluating its tenets and applying them to real conflicts. When War is Unjust takes the just war tradition seriously, and holds its proponents accountable in a critical debate about when - if ever - war can be justified. It is a readable and thought-provoking primer on the history, criteria, and application of just war teaching in Christian churches.

Just War scholarship has adapted to contemporary crises and situations. But its adaptation has spurned debate and conversation—a method and means of pushing its thinking forward. Now the Just War tradition risks becoming marginalized. This concern may seem out of place as Just War literature is proliferating, yet this literature remains welded to traditional conceptualizations of Just War. Caron E. Gentry and Amy E. Eckert argue that the tradition needs to be updated to deal with substate actors within the realm of legitimate authority, private military companies, and the questionable moral difference between the use of conventional and nuclear weapons. Additionally, as recent policy makers and scholars have tried to make the Just War criteria legalistic, they have weakened the tradition's ability to draw from and adjust to its contemporaneous setting. The essays in The Future of Just War seek to reorient the tradition around its core concerns of preventing the unjust use of force by states and limiting the harm inflicted on vulnerable populations such as civilian noncombatants. The pursuit of these challenges involves both a reclaiming of traditional Just War principles from those who would push it toward greater permissiveness with respect to war, as well as the application of Just War principles to emerging issues, such as the growing use of robotics in war or the privatization of force. These essays share a commitment to the idea that the tradition is more about a rigorous application of Just War principles than the satisfaction of a checklist of criteria to be met before waging “just” war in the service of national interest.

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.

Does the United States have the right to defend itself by striking first, or must it wait until an attack is in progress? Is the Bush Doctrine of aggressive preventive action a justified and legal recourse against threats posed by terrorists and rogue states? Tackling one of the most controversial policy issues of the post-September 11 world, Michael Doyle argues that neither the Bush Doctrine nor customary international law is capable of adequately responding to the pressing security threats of our times. In Striking First, Doyle shows how the Bush Doctrine has consistently disregarded a vital distinction in international law between acts of preemption in the face of imminent threats and those of prevention in the face of the growing offensive capability of an enemy. Taking a close look at the Iraq war, the 1998 attack against al Qaeda in Afghanistan, and the Cuban Missile Crisis, among other conflicts, he contends that international law must rely more completely on United Nations Charter procedures and develop clearer standards for dealing with lethal but not immediate threats. After explaining how the UN can again play an important role in enforcing international law and strengthening international guidelines for responding to threats, he describes the rare circumstances when unilateral action is indeed necessary. Based on the 2006 Tanner Lectures at Princeton University, Striking First includes responses by distinguished political theorists Richard Tuck and Jeffrey McMahan and international law scholar Harold Koh, yielding a lively debate that will redefine how--and for what reasons--tomorrow's wars are fought.

The book examines the complex and contested moral and legal issues of preventive warfare.

This volume collects influential and groundbreaking philosophical work on killing in war. A "who's who" of contemporary scholars, this volume serves as a convenient and authoritative collection uniquely suited for university-level teaching and as a reference for ethicists, policymakers, stakeholders, and any student of the morality of war.

In Thick and Thin: Moral Argument at Home and Abroad, Michael Walzer revises and extends the arguments in his influential Spheres of Justice, framing his ideas about justice, social criticism, and national identity in light of the new political world that has arisen in the past three decades. Walzer focuses on two different but interrelated kinds of moral argument: maximalist and minimalist, thick and thin, local and universal. This new edition has a new preface and afterword, written by the author, describing how the reasoning of the book connects with arguments he made in Just and Unjust Wars about the morality of warfare. Walzer's highly literate and fascinating blend of philosophy and historical analysis will appeal not only to those interested in the polemics surrounding Spheres of Justice and Just and Unjust Wars but also to intelligent readers who are more concerned with getting the arguments right.

Just war theory exists to stop armies and countries from using armed force without good cause. But how can we judge whether a war is just? In this original book, John W. Lango takes some distinctive approaches to the ethics of armed conflict. DT A revisionist approach that involves generalising traditional just war principles, so that they are applicable by all sorts of responsible agents to all forms of armed conflict DT A cosmopolitan approach that features the Security Council DT A preventive approach that emphasises alternatives to armed force, including negotiation, nonviolent action and peacekeeping missions DT A human rights approach that encompasses not only armed humanitarian intervention but also armed invasion, armed revolution and all other forms of armed conflict Lango shows how these can be applied to all forms of armed conflict, however large or small: from interstate wars to UN peacekeeping missions, and from civil wars counter-insurgency and counter-terrorism operations.
