The globalisation of Countering Violent Extremism (CVE) policies is the most significant development in counterterrorism policy in the last decade. 1 What began as a rhetorical commitment from a handful of agencies has developed into a plethora of policies, deployed from Finland to the Philippines. 2 In 2016, even the singer Bono adopted the language of CVE, stating before the US Senate Committee on Appropriations that the US should deploy “a Marshall Plan to head off the rise of violent extremism in North Africa, the Middle East, and the Sahel.” 3 Today, the terms ‘radicalisation’,‘extremism’and ‘violent extremism’are bandied about with such frequency and abandon that they have become synonymous with terrorism itself, despite their quite different meanings, and the lack of clarity as to how these concepts relate to one another. 4
