Bringing together the disciplines of International Relations and Science-Technology-Society (STS) on common ground, this work analyzes contemporary security paradigms across a wide axis extending from nuclear deterrence to cyberspace, and autonomous weapons to astropolitics. Positioned by Assoc. Dr. Aslı Çalkıvik not merely as a tool but as a "sociotechnical system" that shapes political and social structures, technology’s transformative impact on military organizations, risk perceptions, and human mobility is demonstrated through concrete examples. Dissecting the changing security architecture of the 21st century and hybrid warfare technologies from an interdisciplinary perspective, the book offers critical awareness at the intersection of technology and politics for both social scientists and engineering professionals alike, serving as a reference source that invites the reader to rethink the modern world through the concept of "technological somnambulism."
