The US-Israeli hybrid warfare against Iran during the "Ramadan War" (February 28 – April 9, 2026) – characterized by the unprecedented martyrdom of the Supreme Leader and senior military commanders – raised a fundamental question for political sociology: what are the discursive processes and mechanisms through which Iranian social cohesion was reconstructed in the face of this war? and how does the official discourse redefine collective identity in the absence of charismatic leadership? The present study employed a qualitative approach and Norman Fairclough's critical discourse analysis (CDA) at three levels – description (formal features of the text), interpretation (situational context of discourse production and consumption), and explanation (linkage with ideology and power) – through a case study of the Ramadan War, including speeches of high-ranking officials, statements of governance institutions, and the slogans and posters of nightly marches. The key findings reveal that the official discourse, through strategies such as "Islamization of the external threat," "sacralization of resistance," and the representation of "us" (the risen nation, the resistant ummah, the front of truth) against "them" (the United States and Israel as the murderers of the martyred leader), combined with the role of domestic media in neutralizing the cognitive war, was able to transform the external threat into a temporary "political-identity capital" and effectively reconstruct cohesion. Consequently, in the era of hybrid warfare, social cohesion is not a static, structural state but a discursive, constructed, and crisis-reproduced process that is heavily dependent on the power of representation, framing, and meaning-making.
