The primary focus of attention in this handbook is the Israeli and American experience of terrorism, although Northern Ireland, France, Spain, Bali are also discussed. There is a tendency to conflate 9/11 with the Israeli experience, blurring the line between ‘tactical’ and ‘strategic’ terrorism (Picco, pp. 71–8). Indeed, it is at the point of definition in the first few articles that this collection is most problematic. Tactical terrorism is something Hezbollah or Hamas practice, it has an objective. Strategic terrorism, as practised by Al Qaeda, attempts to provoke a clash of civilizations. Pico’s argument is that tactical terrorism seeks negotiations while strategic terrorism does not.
