Abstract The presentation attempts to demonstrate that jihadism is not monolithic. In addition, it aims to obliterate generalizing assumption that entire Indonesian jihadists support ISIS.  In the Jemaah Islamiyah body—the biggest militant network in Southeast Asia—for instance, subdivision of its sympathizers is becoming more evident. The dispute is strikingly public after fierce debates over support for the Islamic State of Iraq and Syria (ISIS).  Majelis Mujahidin Indonesia (MMI) and Jemaah Anshar al-Tauhid (JAT)—the splinter cells of the Jemaah Islamiyah—hold contrasting perspectives on the Islamic State. The former refuses to pledge allegiances with ISIS, arguing that the caliphate is invalid, while the latter sees it as legitimate, requiring all its members to render support for the Islamic State. This dispute evidently indicates fragmentation in the Jemaah Islamiyah body in ideology, strategy and political goal.  This presentation will explore such disintegration and its effects to Indonesian Jihadists’ future political struggle.
