Political scientists have long determined that a president¿s relationships with his advisors is crucial in determining an administration¿s policies. Over the last several decades, scholars of the presidency have paid particular attention to the advisory structures and processes involved in foreign policy decision-making. Their work has contributed to the development and refinement of three presidential management models to help frame the analysis of foreign policy-making: (1) formalistic model, (2) collegial model, and (3) competitive model. This book analyzes the management models employed by presidents George W. Bush, Barack Obama, and Donald Trump throughout their presidencies by employing a structured-focus comparison method that is framed on a set of general and standardized questions used to analyze a series of case studies involving their Middle East policies. The book offers the first systematic comparative analysis of presidents Bush, Obama, and Trump¿s management of foreign policy crises.
