Disengagement is the process via which a member of a terror group, radical movement or gang ceases participation in acts of violence. While disengagement has been occurring widely within the mainstream JI community, it is also taking place in Poso among the former and current members of Tanah Runtuh, JI’s Poso affiliate. This begs the question of why. After the Densus 88 raids on the Tanah Runtuh compound in January 2007, the number of terror attacks steeply declined. One might then assume that the Densus raids caused Poso jihadis to realize that the costs of continued terror actions were too high. However, in detailed interviews with 15 former Tanah Runtuh and Kayamanya members, many of whom had been involved in major terror actions, this sort of cost-benefit reasoning was just one part of their disengagement narrative and often not the dominant one. Instead, for most of these individuals, their disengagement was a gradual reflective process, driven by a combination of relational, psychological and rational factors. Employing original fieldwork, this presentation will address the pathways and processes that are leading many Poso jihadis to disengage from violence and address the implications of that disengagement for stability in Poso.
