This book begins with a general overview of what a president needs to understand about the Muslim world, then moves to specific exemplars, Saudi Arabia, Iran, and Turkey. It includes commissioned papers and summary points from a meeting of the Aspen Strategy Group, at which group members and invited guests came together to discuss the background and context, as well as the operational policy challenges of the U.S. government. This is the first of the Aspen Policy Books , a series of books devoted to topics of public policy prepared by the Aspen Strategy Group, the foreign and defense policy program of the Aspen Institute.
