How and Why Do Terrorist Campaigns End?
In order to assess terrorist groups within a broad historical and strategic framework, it is vital to assess how and why terrorist campaigns end. Moreover, if effective counter-terrorism is to be developed, then serious reflection is required regarding what happens during the final phase of terrorist campaigns, and why. This chapter therefore: first, analyses four classic strategies of terrorism and considers why Western democracies have particular difficulty responding to them; second, it reviews six historical patterns of endings for terrorist organisations that have emerged from scholarly research on hundreds of groups; third, it assesses (in light of these six patterns) which counter-terrorism policies have hastened al-Qaida’s demise and which have not, while also reflecting upon the rise of ISIS and its potential future significance.
