The Presidential Difference and Iran’s Foreign Policy Under Khatami from 1997 to 2005 explores the paradigm shift, one that involved a change from confrontation to peaceful relations. The main reason for this alteration rests on Muhammad Khatami’s belief system, whose discourse of “Dialogue Among Civilizations” aiming at coexistence and cooperation assured the international community that Iran would not pursue revolutionary aspirations, but rather seek constructive and meaningful relations based on equality, mutual respect and understanding. Azadeh Momeni argues that the cornerstone of this sea change in foreign policy rests on Khatam’s intellectual thoughts which is characterized by his belief system. What sets this book apart is its unique approach, employing Operational Code Analysis to analyze Khatami’s belief system. Operational Code Analysis is a quantitative method used in political psychology and international relations to understand the decision-making processes and beliefs of political leaders.
