In The Kill Chain, former staff director of the Senate Armed Services Committee Christian Brose argues that the United States' military strategy and technology must evolve to keep pace with the changing nature of modern warfare. Brose contends that America's traditional military approach, focused on large, expensive weapons systems and a reliance on industrial-age thinking, is ill-suited to address the growing threats posed by high-tech adversaries such as China and Russia. Instead, he advocates for a new strategy that emphasizes speed, agility, and innovation, leveraging advances in technology such as artificial intelligence, robotics, and cyber capabilities. The book provides a sobering assessment of the current state of America's military capabilities, and offers a compelling vision for how the country can prepare for the future of warfare.
