Today's protracted asymmetrical conflicts confuse efforts to measure progress, often inviting politics and wishful thinking to replace objective evaluation.

In Assessing War, military historians, social scientists, and military officers explore how observers have analyzed the trajectory of war in American conflicts from the Seven Years’ War through the war in Afghanistan. Drawing on decades of acquired expertise, the contributors examine wartime assessment in both theory and practice and, through alternative dimensions of assessment such as justice and proportionality, the war of ideas and economics. This group of distinguished authors grapples with both conventional and irregular wars and emerging aspects of conflict—such as cyberwar and nation building—that add to the complexities of the modern threat environment. The volume ends with recommendations for practitioners on best approaches while offering sobering conclusions about the challenges of assessing war without politicization or self-delusion.

Covering conflicts from the eighteenth century to today, Assessing War blends focused advice and a uniquely broad set of case studies to ponder vital questions about warfare's past—and its future. The book includes a foreword by Gen. George W. Casey Jr. (USA, Ret.), former chief of staff of the US Army and former commander, Multi-National Force–Iraq.

The optimism that arrived at the end of the cold war and marked the turn of the Millennium was shattered by September 11. In the aftermath of that event it is not unwarranted pessimism that lines the pages of Grave New World, it is unavoidable reality. Terrorism is but one aspect of many other wider concerns for national and international security, and the contributors to this volume not only warn us, but reward us as well with the clarity of their views into—and possible solutions for—a difficult, complicated future. They speak convincingly of the numerous military and non-military challenges that create security problems—whether those are interstate, intrastate, or transnational—many of which are being dangerously overlooked in public policy debates.

The challenges and complexities might seem insurmountable but the first step in solving problems is recognizing that they exist. Grave New World provides an eye-opening assessment of the prospects for peace and security in the 21st century.

Michael E. Brown frames these issues in his Introduction, "Security Challenges in the 21st Century;" and in his summation, "Security Problems and Security Policy in a Grave New World."

Cyber weapons and the possibility of cyber conflict—including interference in foreign political campaigns, industrial sabotage, attacks on infrastructure, and combined military campaigns—require policymakers, scholars, and citizens to rethink twenty-first-century warfare. Yet because cyber capabilities are so new and continually developing, there is little agreement about how they will be deployed, how effective they can be, and how they can be managed.

Written by leading scholars, the fourteen case studies in this volume will help policymakers, scholars, and students make sense of contemporary cyber conflict through historical analogies to past military-technological problems. The chapters are divided into three groups. The first—What Are Cyber Weapons Like?—examines the characteristics of cyber capabilities and how their use for intelligence gathering, signaling, and precision striking compares with earlier technologies for such missions. The second section—What Might Cyber Wars Be Like?—explores how lessons from several wars since the early nineteenth century, including the World Wars, could apply—or not—to cyber conflict in the twenty-first century. The final section—What Is Preventing and/or Managing Cyber Conflict Like?—offers lessons from past cases of managing threatening actors and technologies.
