How have long-standing and unconscious secular assumptions about religion shaped the post-9/11 climate and its wars? Stacey Gutkowski explores this little-examined, yet crucial, element of British perceptions of and policy towards Jihadism over the last decade, to draw critical conclusions about the relationship between war and the secular. She points to a surprisingly coherent body of secular beliefs that have fuelled policies in Iraq, Afghanistan and counter-terrorism, and that have had mixed results - responsible for both positive strategies and tragic errors. The theory Gutkowski develops on the impact of this secular approach to warfare holds a broader global significance, and cannot be viewed as just a British phenomenon. This book addresses ongoing and critical debates, such as the 'overreach' of Western liberal interventionism in the Middle East, and speaks to policy-makers, security analysts and students of IR, Foreign Policy and Security Studies.
