Strategy in this book covers all military activity. The broad purpose is to show how strategy works, using air power and special operations as substantial case studies, but also addressing sea power, nuclear deterrence and information warfare. Although the book comments on the future of air power, the reliability of non-nuclear deterrence, the character of joint warfare, the utility of special warriors, and the limitations of excellence in information warfare, the primary intention is to deepen the understanding of the nature and working of strategy and strategic effect.
