This chapter examines the effectiveness of terrorism in delivering tactical returns. It shows how terrorism is largely ineffective in realising strategic goals. Political goals vary and include secession, overthrowing capitalism, and expelling an occupying force. Additionally, the tactical use of terrorism brings cohesion to a group's organization, ideology, goals, and constituencies. There is no consensus among scholars with regards to the political returns of terrorism. This is due to the methodological problems inherent in the controversy. The chapter then explores the advantages and disadvantages of using coercive intimidation to pursue political conclusions. It includes future studies that may be more inclusive, methodical, and productive.
