The wars in Afghanistan and Iraq resulted in both military and civilian casualties. Hundreds of thousands of Afghan and Iraqi civilians died, which was often described by Allied forces led by the Americans and British using the unfortunate term “collateral damage”. This colossal death toll had consequences ranging from negative attitudes towards the American and British governments and their combat troops to the rise of radicalisation and the recruitment of militants from the West to join terrorist organisations such as Daesh. This chapter contains data from the first survey of its kind on Muslim perceptions of British combat troops and offers important insights into the political determinants of division.
