Ambassador Clovis Maksoud's writing, teaching, and diplomatic practice are a deep wellspring of knowledge. I believe he is around 90, still busy at American University and as a journalist for several media outlets. From him I have learned a lot about the meaning of diversity in the Middle East. He has witnessed so much of the last century's suffering, only occasionally seasoned with diplomatic success by Middle Eastern, U.S. and other governments. Maksoud always keeps the local citizen at the center of his analysis. See this current example: http://www.al-monitor.com/pulse/originals/2013/03/a-painful-sight-of-a-majority-of.html .
