This conclusion presents an overview of the key concepts discussed in the preceding chapters of this book. The book details the causes of political violence. Through a careful analysis of the official language of counter-terrorism, it argues that the discursive strategies employed by the American and British administrations to construct the 'war on terrorism' were the same as those used by leaders and political entrepreneurs in these other conflicts. Importantly, the observation that large-scale political violence is a discursive construction is more than simply ontological; if a campaign of violence like the 'war on terrorism' can be socially and politically constructed, it can also be deconstructed. And, the discourse of counter-terrorism is vulnerable and full of instabilities; it contains contradictions, moral hypocrisies, deliberate deceptions, fabrications and misconceptions which can be exploited.
