This chapter is a contribution to the debate on information resilience and national security from the perspective of countering violent Islamist extremism in the arc of instability. The narratives crafted by various violent Islamist extremists are a form of information resilience, but in this case, they act as counterforces, hindering state efforts to prepare for and withstand the onslaughts of terror groups. This challenge is particularly pronounced in weak and fragile states within the arc of instability. The aims of the chapter are threefold: to explore the information resilience of terrorist groups vying for power in the arc of instability; to examine the reactions and responses that extremism has produced in the commercial media; and, finally, to discuss the key challenges that governments are grappling with in controlling media content that is seen as having the potential to destabilise the already fragile security situation.
