Military Strategy in the 21st Century explores military strategy and the new challenges facing Western democracies in the twenty- first century, including strategy in cyber operations and peacekeeping, challenges for civil-military relations, and the strategic choices of great powers and small states.

The volume contributes to a better understanding of military strategy in the twenty- first century, through exploring strategy from three perspectives: first, the study of strategy, and how our understanding of strategy has changed over time; second, new areas for strategic theory, such as peacekeeping and cyberspace; and third, the makers of strategy, and why states choose suboptimal strategies.

With the increasing number of threats challenging strategy makers, such as great power rivalry, terrorism, intrastate wars, and transnational criminal organisations, Military Strategy in the 21st Century will be of great value to scholars of IR, Security Studies, Strategic Studies, and War Studies as well as policymakers and practitioners working with military strategy in particular and international security and war in general. The chapters were originally published as a special issue of the Journal of Strategic Studies.
