Examines the impact of new technologies on twenty-first-century crisis management and armed conflict, as well as the unprecedented number and types of actors involved in current and potential flash-points. The book's basic thesis is that new technologies are changing how wars are fought and providing a broadening range of escalation options. Coalition Management and Escalation Control in a Multinuclear World examines the impact of new technologies on twenty-first-century crisis management and armed conflict, as well as the unprecedented number and types of actors involved in current and potential flash-points. The book's basic thesis is that new technologies are changing how wars are fought and providing a broadening range of escalation options. Cyber weapons and artificial intelligence, as well as social media, blur traditional escalation thresholds with important consequences for deterrence. Nuclear weapons possessors, especially nations and powers new to their use, may have differing strategies concerning how, when, why, or where such weapons should be used either for purposes of deterrence or as actual warfighting instruments. Today's global map differs drastically from all previous eras, not only in the types and numbers of actors but also in the level of lethality, as well as the range and accuracy of weapons available with which to threaten or actually conduct battle. A world of Great Power competition, together with non-state armed groups contains risks for miscalculation including the possibility of catalytic warfare.
