The Kill Chain: Defending America in the Future of High-Tech Warfare

Christian Brose, a former senior advisor to Senator John McCain, examines how emerging technologies are affecting American military superiority. For decades, the United States has maintained uncontested dominance in military capability and weapons systems. This advantage is now eroding as new technologies develop and rivals like China expand their military strength, putting America at risk in future conflicts. Brose argues that artificial intelligence, autonomous systems, and other emerging technologies are reshaping global industries and will fundamentally alter American defense strategy. The book addresses existential risks ahead and proposes how the military can adapt through new thinking and technology. According to Brose, America must develop a battle network—called "the kill chain"—that allows rapid threat assessment, decision-making, and military action. The book examines threats from China, Russia, and other sources, while offering perspectives on how advanced technologies can be applied to prevent war, deter aggression, and maintain peace.
