This study aims to elucidate the representational mechanisms employed by Iran International television network in covering the Iran-Israel hostility known as the "Twelve-Day War," and the nexus between news discourse and macro-level power structures. Within the qualitative paradigm, this research applies Critical Discourse Analysis (CDA) based on Fairclough's three-dimensional model, examining the textual corpus across three levels: description (formal and lexical analysis), interpretation (processes of text production and consumption), and explanation (socio-ideological context analysis). Quantitative content analysis extracts message frequency, thematic distribution, and patterns of news sourcing. At the descriptive level, data analysis reveals that the network, by deploying lexical mechanisms such as "labeling" and "evaluative naming," alongside grammatical structures including passivization and nominalization, has attributed agency for the initiation and escalation of the crisis to Iran's political structure. Furthermore, through the use of conceptual metaphors and intensifying adverbs, it has created an asymmetry in the representation of the concepts of aggression and defense. At the interpretive level, findings demonstrate that news texts have been produced on the basis of specific ideological presuppositions. By employing intertextual techniques, chains of semantic equivalence, and preferred readings, the network has guided audiences toward accepting its desired narrative while foreclosing alternative interpretations. At the explanatory level, results indicate that media's representational pattern constitutes a hegemonic mechanism aimed at "delegitimizing" Iran's defense doctrine and consolidating an "othering" discourse. Concurrently, through the "naturalization" of foreign aggression and the "de-securitization" of the threat, the central signifier of its narrative has been anchored in domestic blame attribution.
