Chapter 2 has established that terrorism is inextricably linked to communication. There are, however, two major obstacles to understanding the role of communication. On the one hand is the lack of solid explanatory frameworks in the field of terrorism studies within which to “place” the exchange, sharing, and processing of information. On the other hand is the existence of assumptions shaped by the way terrorism has been studied over decades. They do not even allow us to register communication as relevant to the study of terrorism — what has been called in the previous chapter the “terrorism paradigm.” The combination of these aspects is an hindrance to understanding the role of communication technologies, media organisations, and the effects that messages carried by the media can have, for instance, in the individual development of radical views, mobilisation of terrorist groups across borders, or the weaving of a terrorist plot.
