<p>This study examines how U.S. and European media framed the Trump and Zelenskyy Oval Office meeting through Hallin’s spheres of discourse: consensus, legitimate controversy, and deviance. Using Latent Dirichlet Allocation (LDA) and Contrastive LDA (cLDA), the study identifies shared and divergent narratives in transatlantic media coverage. Findings indicate that both media ecosystems placed diplomatic engagement and security concerns within the Sphere of Consensus, framing Zelenskyy’s visit as a critical diplomatic moment. However, framing differed: European media emphasized NATO cohesion, multilateral diplomacy, and critiques of U.S. geopolitical influence, while U.S. coverage internalized the issue within domestic political debates, highlighting partisan divisions and financial concerns. Linguistic analysis shows that European media used more supportive language, reinforcing Ukraine’s role as a key ally, while U.S. media introduced skepticism, positioning continued aid as a subject of political contention. This study offers a systematic, empirical extension of Hallin’s spheres of discourse by applying Latent Dirichlet Allocation (LDA), Contrastive LDA (cLDA), and linguistic framing analysis to a cross regional corpus. It identifies not only thematic alignments and divergences but also operationalizes Hallin’s concepts with quantifiable thresholds. Findings also reveal that both U.S. and European media largely portray the Trump and Zelenskyy Oval Office meeting as diplomatically significant, yet differ in their framing of geopolitical agency and political legitimacy. This study advances comparative media theory by demonstrating the empirical detectability of Hallin’s spheres in international framing and highlight how national media ecosystems filter global events through regionally situated ideological lenses.</p>
