This book has been many years in the making, as the author explains in his Preface, though he wrote most of the actual text during his year as senior Research Fellow with the Center for Strategic Intelligence Research. The author was for many years Dean of the School of Intelligence Studies at the Joint Military Intelligence College. Even though it may appear that the book could have been written by any good historian or Southeast Asia regional specialist, this work is illuminated by the author's more than three decades of service within the national Intelligence Community. His regional expertise often has been applied to special assessments for the Community. With a knowledge of Islam unparalleled among his peers and an unquenchable thirst for determining how the goals of this religion might play out in areas far from the focus of most policymakers' current attention, the author has made the most of this opportunity to acquaint the Intelligence Community and a broader readership with a strategic appreciation of a region in the throes of reconciling secular and religious forces.
