Discourse since September 11, 2001 has constrained and shaped public discussion and debate surrounding terrorism worldwide. Social actors in the Americas, Europe, Asia, the Middle East and elsewhere employ the language of the "e;war on terror"e; to explain, react to, justify and understand a broad range of political, economic and social phenomena. Discourse, War and Terrorism explores the discursive production of identities, the shaping of ideologies, and the formation of collective understandings in response to 9/11 in the United States and around the world. At issue are how enemies are defined and identified, how political leaders and citizens react, and how members of societies understand their position in the world in relation to terrorism. Contributors to this volume represent diverse sub-fields involved in the critical study of language, including perspectives from sociocultural linguistics, communication, media, cultural and political studies.
