This book analyzes some of the commonly accepted causes of radicalization within the context of four organizations in eastern Africa. It identifies and discusses the facilitating agents needed to enable radicalization and recruitment, and answers one of the most fundamental questions the public and scholars alike are confronted with: Why are all people confronted with the same external circumstances not being radicalized? Practitioners and policymakers will realize that although one can learn from the experiences of others, developing and implementing effective counter-radicalization strategies should be shaped around the unique circumstances of the specific organization.
