This book clarifies Khomeini’s views on nationalism, sectarianism, and peace and war by putting the Iran-Iraq war at center of understanding of Khomeini’s ideology. Moreover, by making comparisons between Khomeini’s thoughts before and after the revolution with his words during the Iran-Iraq war, this book helps us see how his discourse during the conflict was shaped by such thoughts. Also, such a comparison helps us understand the complexities of Khomeini’s doctrines and their evolvements. Additionally, by offering a unique set of methodological tools, this book introduces a new way to study political leaders in Iran and other parts of the Middle East.
