This book examines current American military doctrine as it relates to antiterrorism, the prevention of terrorist activities directed at U.S. military personnel, equipment, and resources. The study uses a doctrinal analysis model based upon the work of one of the foremost airpower doctrine proponents of the last twenty years. By a rigorous analysis of the fundamental, environmental, and organizational aspects of current antiterrorism doctrine overlaid with the strategic, operational, and tactical aspects, the doctrine in force is shown to have some shortcomings. When the results of the analysis are superimposed on selected case studies, the deficiencies are validated. Recommendations for reforms are then proposed to address the inadequacies. The result is a more robust method of defeating the terrorist threat.
