About Article

While it is sensible that governments and academics endeavour to assess the effectiveness of counterterrorism policies, this article argues that it is almost impossible to measure arithmetically the outcome of counterterrorism efforts for a variety of reasons. How ever, this does not mean that the effect of governmental policy cannot and should not be assessed. This article argues that it is not necessarily the policy measures and their intended results as such, but much more the way in which they are presented and perceived, that determine the overall effect of the policy in question. The article intro duces the concept of ‘performativity’, which involves the extent to which a national government, by means of its official counterterrorism policy and corresponding discourse, is successful in selling its representation of events, its set of solutions to the terrorist problem, as well as being able to set the tone for the overall discourse on terrorism and counterterrorism. Due to the distinct relation between the performative power of coun terterrorism efforts and the arc of violence carried out by terrorist movements, analysing the level of performativity will provide an indication to the effectiveness of counterter rorism policies. It is argued that a low level of performative power generally has a more rapidly neutralising effect on radicalisation and political violence than large-scale, public counterterrorism efforts.
