This book investigates whether traditional Just War theory remains applicable to the emerging and ambiguous domain of cyberwarfare. Fritz Allhoff, a philosopher specializing in applied ethics, utilizes the established framework of the Just War tradition to evaluate the moral and legal implications of digital conflict. The text argues that the unique characteristics of cyber-attacks necessitate a rigorous re-evaluation of how international law and ethical standards define acts of aggression and state responsibility.

Experts identify this work as a significant contribution to the intersection of technology and political philosophy. Readers frequently note the academic density of the prose, which is intended for those familiar with ethical frameworks and international relations theory.
