Behind headlines, social media, and fear-mongering lies an ISIS threat not of ideology, but rather opportunity. ISIS is a maestro at maximizing political instability and discontent, parlaying them into new potential strongholds and followers. In this monograph, Namrata Goswami expertly unmasks this underground version of ISIS, and with it, uncovers vulnerabilities to previously untapped ISIS targets in Bangladesh, Burma, India, and Indonesia. This monograph provides a much needed fact-based perspective to explain the success of ISIS in both spreading its ideology and recruitment base. Drawing upon historical examples and parallels, the author describes a movement that is very strategic in its emphases. Even existing scholars in the region are apt to find new and invaluable insights on where sociological, cultural, and political variables of this region intersect with ISIS opportunity.
