The threat posed by radicalism and terrorism is not new. However, with the end of the Cold War, while terrorism and extremism anywhere and associated with any religion is a major concern, what has come to dominate the security radar screen of Southeast Asian countries (and elsewhere) is the extremism and
terrorism associated with Islam. This is particularly of concern in countries such as Indonesia, Malaysia, Singapore, Thailand and the Philippines. While agent inspired and induced radicalisation has long dominated the phenomenon, a relatively new concern is what is described as ‘self-radicalisation’. This is brought about by self-learning, mainly of published materials and of increasingly growing
importance, through the Internet. This study will examine the following issues: What is self-radicalisation, why is it increasingly important, the Singapore narrative and more important, what to do.
