The volume considers Clausewitz's timeless On War against the background of actual armed conflict. With scholars from a range of disciplines and countries, it throws new light on a classic text and contemporary issues. A closer reading of Clausewitz gives rise to the following implications for warfare in the 21st century. First, the war on terror, as with all wars, is irreversibly political in nature, and requires a decidedly political approach. (...) Second, globalization intensifies the role of politics, and indeed reduces reaction time within all three elements of Clausewitz's wondrous trinity, which is quite different from so called trinitarian war and which is Clausewitz's true legacy. Third, policys subordinating influence over warfare suggests that the overarching political goal for grand strategy in the 21st century should be the containment of violence, with the intent to diminish armed conflict as precondition for establishing democracies.
