The study of United States foreign policy has recently been invigorated by the introduction of Graham Allison's bureaucratic politics model (BPM). The basic unit of analysis of the BPM is governmental action viewed as political resultant. In Allison's words, the actions of governments are ‘resultants in the sense that what happens is not chosen as a solution to a problem but rather results from compromise, conflict, and confusion of officials with diverse interests and unequal influence…’. The BPM assumes that different players will have different perspectives toward similar problems, that is, they will each see different ‘faces’ of the same issue. The basic assumption of the BPM as it is applied to United States foreign policy toward Latin America by scholars such as Abraham Lowenthal is that United States decision-makes, who share power in both the formulation and implementation of policy, have differing points of view because of their differing organizational and personal perspectives.
