Counterterrorism is both a reaction to and an anticipation of the activities of those who wield terror for political purposes. Counterterrorism pits itself against terrorism, aimed at ending or at least limiting its operations, spread, and damage. As Richard English has acknowledged, non-state terrorism has much less impact on the world than the counterterrorism it elicits. The vast powers at the disposal of states and their reactive tendency to military methods, such as after 9/11, make this entirely predictable. Fiona de Londras’ examination of transnational counterterrorism ably documents how states acting in concert have reshaped the world, particularly in the post 9/11 era. Guendalina Simoncini’s book on Tunisia clearly illustrates how counterterrorism can be used to enable the establishment of an authoritarian regime in Tunisia and the resultant disastrous consequences for that society.
