TEVEN OMEROY An Untaken Road Titles in the Series The Other Space Race: Eisenhower and the Quest for Aerospace Security Transforming War —Paul J. Springer, editor To ensure success, the conduct of war requires rapid and effective adapta- tion to changing circumstances. While every conflict involves a degree of flexibility and innovation, there are certain changes that have occurred throughout history that stand out because they fundamentally altered the conduct of warfare. The most prominent of these changes have been labeled “Revolutions in Military Affairs” (RMAs). These so-called revolu- tions include technological innovations as well as entirely new approaches to strategy. Revolutionary ideas in military theory, doctrine, and opera- tions have also permanently changed the methods, means, and objectives of warfare. This series examines fundamental transformations that have occurred in warfare. It places particular emphasis upon RMAs to examine how the development of a new idea or device can alter not only the conduct of wars, but their effect upon participants, supporters, and uninvolved parties. The unifying concept of the series is not geographical or temporal; rather, it is the notion of change in conflict and its subsequent impact. This has allowed the incorporation of a wide variety of scholars, approaches, disciplines, and conclusions to be brought under the umbrella of the series. The works include biographies, examinations of transformative events, and analyses of key technological innovations that provide a greater understanding of how and why modern conflict is carried out, and how it may change the battlefields of the future.
