This volume examines the complex and vitally important ethical questions connected with the deployment of nuclear weapons and their use as a deterrent. A number of the essays contained here have already established themselves as penetrating and significant contributions to the debate on nuclear ethics. They have been revised to bring out their unity and coherence, and are integrated with new essays. The books exceptional rigor and clarity make it valuable whether the reader's concern with nuclear ethics is professional or (...) personal. Part I explores the morality of nuclear deterrrence from each of the two dominant traditions in moral philosophy, deontology and consequentialism, and points out a number of interesting ethical dilemmas. Part II criticizes a variety of alternatives to deterrence - unilateral nuclear disarmament, world government, strategic defense against ballistic missiles, and nuclear coercion - and argues for mutual nuclear disarmament as a realistic and desirable long-run alternative.

The paper addresses several issues in the morality of cyberwar and cyberwarfare, defined as one nation's attacks on the governmental or civilian information systems of another nation. It sketches the diverse technical ways in which an attack may occur, including denial-of-service attacks and the insertion of various forms of malware. It argues that existing international law and widely discussed principles of Just War Theory do not straightforwardly apply to cyberwarfare, and many forms of cyberwarfare differ from previous forms of warfare (...) in neither injuring nor killing human beings, nor causing lasting physical damage ? but can nevertheless cause serious harm to a nation's vital interests. Another dissimilarity with traditional warfare is in the degree of knowledge of the identity of an attacker (the ?attribution problem?). The paper argues that cyberwarfare is not amenable to regulation by international pacts and that we can expect long periods of low-level, multilateral cyberwarfare, a Cyber Cold War, as a game-theoretic equilibrium is sought,. The paper laments the lack of a cyberwarfare policy, and concludes that it is only by applying game-theoretic principles that strategies can be discovered that are both moral and effective in suppressing overall harm to all parties in the long run.
