James Johnson

Now that mankind has created the capability of destroying itself through nuclear technology, is it still possible to think in terms of a "just war"? Johnson argues that it is, and in the context of specific case studies he offers moral guidelines for addressing such major contemporary problems as terrorist activity in a foreign country, an individual’s conscientious objection to military service, and an American defense policy that requires development of weapons that may be morally employed in case of need. "Remarkable.... A thoughtful and even profound book, which can be warmly recommended."—Adam Roberts, _New Society_ __ "[A] wise, prudential, and moral thesis.... A most important book, one that all Americans who can should read."—George Armstrong Kelly, _Political Science Quarterly_ __ "At its heart, _Can Modern War be Just? _Is a challenge to the common assumption that any modern war must be total—an unrestrained, spasmodic release of one’s entire destructive capacity against the whole of the enemy’s population."—Richard Allen, _Journal of Religious Ethics_ __ "Johnson... seriously attempt[s] to balance principles and respect facts. For this he is to be praised."—Gary Jason, _Chronicles of Culture_ __ "Johnson’s application of just war doctrine to the hardest problems of contemporary warfare is both morally sensitive and intellectually bold. Readers will sometimes disagree with his arguments, but they will be forced to think hard, and they will learn what it is to work within a moral tradition."—Michael Walzer

This Companion provides scholars and graduates, serving and retired military professionals, members of the diplomatic and policy communities concerned with security affairs, and legal professionals who deal with military law and with international law on armed conflicts, with a comprehensive and authoritative state-of-the-art review of current research in the area of military ethics. Topics in this volume reflect both perennial and pressing contemporary issues in the ethics of the use of military force and are written by established professionals and respected commentators.

Christians have historically differed as to whether the wrongness of an act is to be located in the objective character of the act or in the intention of the agent. By blurring this distinction, Alain Epp Weaver fails to see the real principle of consistency that unites Augustine's analyses of warfare and lying. Likewise, by not appreciating the fact that Augustine analyzes the wrongness of the act in terms of intention whereas Yoder analyzes its wrongness in terms of its objective character, Weaver proposes a conversation between two figures who lack the framework of shared assumptions that makes engagement in conversation possible

In its classic form the doctrine of the just war, whether enunciated by theological or secular theorists, had two main components: the jus ad bellum, which defined the morally acceptable limits within which a sovereign could and even should go to war, and the jus in bello, which set limits to the conduct of war. By contrast, today the problem of just limitation of war is addressed almost entirely by legal and theoretical attempts to refine the jus in bello, while there exists only a morally truncated and politically ineffective jus ad bellum. What is the contemporary status of the jus ad bellum and what makes it politically and morally inadequate are the issues I wish to address directly in this paper. Indirectly, however, I wish to speak to more fundamental questions: what are the ingredients of a moral doctrine limiting resort to war, and what is required for this to be politically workable as well? The final goal, which is far beyond the scope of this paper, is to reconstruct for our own time a doctrine on the just limitation of war which would restore the dual thrust of just war doctrine in its classic form.

This essay explores the idea of just war in two ways. Part I outlines the formation, early development, and substantive content of just war tradition in its classic form, sketches the subsequent development of this idea in the modern period, and examines three benchmarks in the recovery of just war thinking in American thought over the last four decades. Part II identifies and critiques several prominent themes in contemporary just war discourse, testing them against the context, purpose, and content of the just war idea in its classic form. My argument throughout is that the historical substance of just war tradition needs to be respected in contemporary just war discourse, both to discipline that discourse and to engage contemporary moral reflection with the values embodied in just war tradition.

Can AI solve the ethical, moral, and political dilemmas of warfare? How is artificial intelligence (AI)-enabled warfare changing the way we think about the ethical-political dilemmas and practice of war? This article explores the key elements of the ethical, moral, and political dilemmas of human-machine interactions in modern digitized warfare. It provides a counterpoint to the argument that AI “rational” efficiency can simultaneously offer a viable solution to human psychological and biological fallibility in combat while retaining “meaningful” human control over the war machine. This Panglossian assumption neglects the psychological features of human-machine interactions, the pace at which future AI-enabled conflict will be fought, and the complex and chaotic nature of modern war. The article expounds key psychological insights of human-machine interactions to elucidate how AI shapes our capacity to think about future warfare's political and ethical dilemmas. It argues that through the psychological process of human-machine integration, AI will not merely force-multiply existing advanced weaponry but will become de facto strategic actors in warfare – the “AI commander problem.”

Beginning with the support given by religious groups to humanitarian intervention for the protection of basic human rights in the debates of the 1990s, this essay examines the use of the human rights idea in relation to international law on armed conflict, the “Responsibility To Protect” doctrine, and the development of the idea of sovereignty associated with the “Westphalian system” of international order, identifying a dilemma: that the idea of human rights undergirds both the principle of non-intervention in the internal affairs of states and the idea of an international responsibility for humanitarian intervention in cases of oppression. The pre-Westphalian conception of sovereignty as moral responsibility for the common good is then examined as an alternative that avoids this dilemma, and the essay concludes by suggesting that religious ethics also has other resources that, if used, may shed useful light on resolving this problem

Beginning with a sketch of the major moral ideas contained in just war tradition, this essay applies them to three controverted issues in contemporary military debate: nuclear deterrence strategy, the strategic defense initiative, and the possibility of building and deploying fractional megatonnage nuclear weapons on delivery vehicles of extremely high accuracy. It is argued that, in terms of the criteria of just war tradition, deterrence in its present form poses grave moral problems. The two new weapons systems are then examined in terms of whether, by just war criteria, they represent more moral means of defense than contemporary nuclear deterrence.

Three recent books focus, in different ways, on the idea of human rights and its relation to religion and religious ethics. All three books discussed here address criticisms of the human rights idea and seek to establish the relationship of religion and human rights with regard to the field of policy. The present discussion begins with an overview that places these three books in the larger context of the development of the human rights idea and its historical relationship with religion. It then turns to Little's book, next to the collection of essays edited by Twiss, Simion, and Petersen, which is described internally as a Festschrift for Little, and then to Hogan's book, and in the final section it explores comparisons among the books.
