Most studies of the use of conventional military force by the United States in the twentieth century tend to characterize the decision making process in terms of a unitary state and a unitary presidential decision maker. One alternative to this approach is the Bureaucratic Politics paradigm proposed by Graham Allison. To test the explanatory power of this decision making model in the post-Vietnam era, this thesis applies the specific propositions of Graham Allison's "Governmental Politics Model" concerning the use of military force, to selected case studies. In an attempt to determine the explanatory power of Allison's Governmental Politics model in the wake of Vietnam, this thesis draws on case studies ranging from the Dominican Republic intervention to the recent invasion of Panama. This thesis seeks to measure the theory to present reality. / Master of Arts
