This foreign policy analysis textbook is written especially for students studying to become national security professionals. It translates academic knowledge about the complex influences on American foreign policymaking into an intuitive, cohesive, and practical set of analytic tools. The focus here is not theory for the sake of theory, but rather to translate theory into practice. Classic paradigms are adapted to fit the changing realities of the contemporary national security environment. For example, the growing centrality of the White House is seen in the ‘palace politics’ of the president’s inner circle, and the growth of the national security apparatus introduces new dimensions to organizational processes and subordinate levels of bureaucratic politics. Real-world case studies are used throughout to allow students to apply theory. These comprise recent events that draw impartially across partisan lines and encompass a variety of diplomatic, military, and economic and trade issues.
