International terrorism as a force of homogenization? A constructivist approach to understanding cross-national threat perceptions and responses

Abstract

Has the emergence of international jihadist terrorism led to common threat perceptions and responses in Europe? The article argues that the homogenization thesis is based around a misguided functionalist notion of a single ‘optimal response’ to an alleged new and potentially catastrophic kind of threat with uniform consequences for all ‘Western’ countries. Drawing on insights from different bodies of literature, the article elaborates a theoretical framework to understand variations in threat perceptions vis-à-vis international terrorism and enrich the socio-linguistic securitization approach of Barry Buzan, Ole Wæver and Jaap de Wilde (Security: a new framework for analysis, London: Lynne Reinner, 1998). The article then empirically examines the rise and fall of threat perceptions among selected European publics between 2000 and 2008. Threat perceptions did converge in the aftermath of the 9/11 attacks, but soon afterward started diverging. The article considers the reasons for this finding as well as the implication for the evolution of counter-terrorist policies in the European Union.
