War proved a seminal influence on the shape of the 20th century. This collection provides various essays addressing the phenomenon of war as viewed through the eyes of the fin de siecle. Leading scholars of war, international relations, and international law offer general or specific insights into war's consequences during the last one hundred years. Combined, the essays demonstrate the centrality of 20th century war to the development of the modern state system, international jurisprudence, and contemporary society. Donald Watt provides an overview of the use of the term war in its legal and practical sense. John Lynn addresses the transformation of military professional forces through the century. Donna Arzt explores the slow convergence of humanitarian law with human rights laws as witnessed in the latter half of the century. The contours of the national security state that emerged in many forms through the late century are detailed in contributions by Lawrence Aronsen, Geoffrey Smith, and Gary Hess. Finally, efforts to avert war through arms control, disarmament, arms reduction, and peace-keeping are examined in essays by Norman Hillmer and Erik Goldstein.

Grand strategy, strategy, and tactics--the three layers of policy and action inherent to all military efforts--are the focus of this historical analysis of the dynamics of the Vietnam War. The American theory of counterrevolutionary warfare is examined in light of American military practice, especially that of the Marine Corps, during the period of America's greatest involvement, 1965-1972, and at the site of the most intense combat, the five northern provinces known as I Corps. Drawing from two schools of thought that diverge over the appropriate strategy America should have pursued in South Vietnam, this inquiry indicates that both the number of troops and their tactical employment proved inadequate for redressing the threat within the parameters America set for itself. Specifically, this work demonstrates that the counterrevolutionary warfare strategy postulated for Vietnam was largely ignored in some quarters, and sowed the seeds of defeat in others.
