It sheds light on the different ways ISIS exploits social media communications to affect the American security. After the application of Relative deprivation, Framing and Violence concepts which are part of social movement theory, in addition to Hypodermic Effects, a concept from Media Effects Theory, the findings revealed that ISIS increases individuals’ sense of deprivation and frames its message according to what fits those individuals to make them involve in jihad. Thus, those recruits may pose a threat to their homeland by radicalizing others, carrying out lone wolf attacks or raising funds to support the advancement of the terrorist group.otherexaminers for accepting to read and to examineThesis
