The key to any successful strategic campaign begins with an analysis of both the friendly and threat strategic center of gravity. This analysis drives the development of the campaign plan by familiarizing planners with an understanding of how both belligerents organize, fight, and make decisions. Consequently, the improper identification or miscalculation of the center of gravity will lead to the misapplication of the elements of national power and ultimately to a campaign plan that will not meet the stated strategic objectives. While Joint and service doctrine/manuals generally agree on a common definition of center of gravity, considerable discrepancies still exist regarding the specific nature of center of gravity and its relationship to critical vulnerabilities. Dr. Joe Strange, a professor at the Marine Corps University, makes a recommendation for defining this relationship. He has developed a model that bridges the gap between the center of gravity and critical vulnerabilities by identifying critical capabilities and critical requirements. Dr. Strange posits that it is necessary to understand the center of gravity, critical capability, critical requirement, and critical vulnerability relationship in order to grasp fully the environment in which this campaign will take place. This model will be used for this analysis. The purpose of this paper is three-fold: first, to determine a workable definition of terrorism and how this definition applies to the new religiously based terrorism the world witnessed on 11 September; second, to conduct a comprehensive strategic level center of gravity analysis that will identify the relative strength and weaknesses of the U.S. led coalition and the al Qaeda terrorist network and; third, to present potential friendly and enemy response strategies.
