The present study dissects the internal logic of U.S. President Donald Trump's psychological-media operations on the Truth Social platform during the critical "40-Day War" period and immediate post-ceasefire days (February 28 to April 23, 2026). The primary objective of this study is to extract the strategic pattern and media behavioral model of the actor in confronting this military and media system crisis. The methodology is based on a mixed-methods design (quantitative-qualitative content analysis), strategic coding, framing, and time-series analysis of a corpus comprising 996 posts (including 730 textual posts, 161 of which are directly Iran-related). Quantitative findings indicate that despite representing 22.1% of textual posts, Iran-related messages contained 29.45% of total linguistic tokens, demonstrating higher semantic compression and lexical density compared to the overall corpus average. At the linguistic level, the decisive 4.29:1 dominance of goal-oriented over result-oriented language regarding Iran indicates a "future-selling" strategy and an attempt to "adjust the mental reference point" of the audience. Temporal analysis formulated Trump's activism into four distinct phases: "Blitzkrieg and power vacuum," "Shifting the front from foreign to domestic," "Coercive diplomacy and nuclear shock," and "Final siege and victory consolidation." The data led to the design of a final "mediatized psychological operations" model categorized under six components: "power display," "inducing gaps," "maintaining pressure while keeping the deal open," "future-selling," "controlled saturation and dispersion of narrative," and "capturing the final narrative." The findings confirm that during this period, Truth Social served not merely as a news outlet, but as a narrative infrastructure and a "magic circle" in the service of cognitive warfare architecture and perception management against the national will of Iran.
