The article deals with the process of formation of morality that justifies terrorism. The author analyzes the conditions which lead to the employment of terrorism as a method of reaction by an agent in an environment. Finally, the author considers the “bottom-up strategy of inclusive counterterrorism”, which implies the marginalization of terrorism among the local population through interaction with the most oppressed groups. The role of non-state actors, in particular NGOs, in the implementation of the “bottom-up strategy of countering terrorism” is assessed.
