Cognitive Warfare in the Age of Unpeace: Strategies, Defenses, and the New Battlefield of the Mind is a definitive examination of the emergent arena of cognitive warfare-a battlefield where consciousness and cognition are under siege. Rooted in the historical lineage of warfare, this seminal tome charts a course from the stratagems of yesteryear's influence operations to the digital subversions that define our current epoch. The book is structured to provide a layered understanding of the subject. Part I lays the foundation, explaining how the age of unpeace has given rise to a new form of warfare that exists between peace and war, where the battle for influence is paramount. Part II describes the modern tools at the disposal of state and non-state actors, including AI and neurotechnological advancements, and the ways in which these tools can manipulate and coerce on a mass scale. Through real-world case studies, Part III illustrates the practical application of cognitive strategies and the impact of such warfare on democracies, highlighting the need for robust countermeasures. In Part IV, the focus shifts to strategic insights, examining both offensive strategies for influence and subversion and the defensive strategies necessary to maintain cognitive sovereignty. The latter sections, Parts V and VI, provide a forward-looking perspective on building societal and governmental defenses against cognitive attacks. These include fostering societal resilience through public education, developing policy and governance frameworks, and addressing the ethical dimensions of cognitive defense. The final chapters speculate on the future trajectory of cognitive warfare, emphasizing the importance of international cooperation and the establishment of 'cognitive peace'. With its conclusion and appendices providing a roadmap and additional resources, this book stands as an essential guide for policymakers, security experts, academics and citizens alike in understanding and countering the sophisticated threat of cognitive warfare in our increasingly interconnected world.
