The 9/11 vents have left an American people riddled with pain and trauma with deep wounds, both physical and psychic. The days following this attack were marked by a situation of permanent psychosis, marked by fear and uncertainty, because it was an almost apocalyptic situation. The reaction of George Walker Bush’s administration was, first, to consider this attack as an act of war against the United States of America by inventing a motive for war, casus belli, and finally by equipping itself with discursive, political, propagandist means to forge an ultimate conviction of a war case with the full support of the American people. Fear is a form of intrinsic motivation, and, above all, it can be produced by a number of endogenous as well as exogenous factors. Neoconservatives have understood the manifestation of this natural phenomenon and know how to use it to legitimize imperialist agendas. This study aims to revisit this context of production and promotion “Apocalyptic” Discourse to Provoke National Adhesion to a Controversial Conflict.
