The comparative assessment of public statements released by certain Islamist groups/leaders highlights the continuous process of tailoring the response to topics seen as an offence to Muslims as a whole, in order to boost the impact of allegations linked to the thesis of their oppression by the West and to justify terrorist actions. As far as propaganda is concerned, one can notice the change in the discoursive characteristics of the texts and the dissemination means depending on the chosen theme, intended objectives and aimed targets.
