This document analyzes the UK's counterterrorism policy and whether it sufficiently accounts for non-Islamic terrorist groups. It finds that while Islamic groups tend to be more deadly, they make up less than a third of terrorist organizations globally. In the UK in 2014, none of the 103 terrorism incidents were committed by Islamic groups. The document recommends further research on the effectiveness of current policy and consideration of either implementing new policies focused on non-Islamic terrorism, updating current policies to be more inclusive, or making no changes if research finds Islamic terrorism remains the primary threat. The author's preferred option is a combination of the first two - updating some policies and creating new ones where groups differ in how they respond to counterterrorism measures
