This book explores topical issues in military ethics by according peace a central role within an interdisciplinary framework. Whilst war and peace have traditionally been viewed through the lens of philosophical enquiry, political issues and theological ideas - as well as common sense - have also influenced people understanding of armed conflicts with regards to both the moral issues they raise and the policies and actions they require. Comprised of fourteen essays on the role and application of peace, the book places emphasis on it philosophical, moral, theological, technological, and practical implications. Starting with an overview of Kantian perspectives on peace, it moves to discussions of the Just War debates, religious conceptualizations of peace, and the role of peace in modern war technology and cyber-security. Finally concluding with discussions of the psychological and medical impacts of war and peace on both the individual and the larger society, this collection offers a contribution to the field and will be of interest to a wide audience.
