Research objective: This article continues the scholarly tradition of uncovering the rhetorical practices that influence audiences’ perceptions, beliefs, and behaviours towards nuclear actors and issues and examines how the Romanian mass media reports on nuclear threats against the backdrop of the Russian invasion of Ukraine. THE RESEARCH PROBLEM AND METHODS: This article conducts a detailed examination of how media coverage of nuclear-related topics influences public perceptions, generating a feeling of urgency and potentially leading to mass panic and hysteria. The study employed a quantitative methodology, conducting content analysis on a selection of 190 online news articles from the primary Romanian press agencies (Mediafax and Agerpress) published between February 24, 2022, and February 24, 2023. Employing an inductive approach, our analysis was guided by frames identified during the examination of the sample material. THE PROCESS OF ARGUMENTATION: Nuclear threats and other related issues were frequently reported in the media in the post-World War 2 period. Given the history of media coverage of this topic, it is perhaps not surprising that a return to reporting nuclear threats has dominated the media discourse since the beginning of the Russian invasion of Ukraine in February 2022. RESEARCH RESULTS: The results of our study reveal two main frames used to report issues related to nuclear threats during the war in Ukraine: a historical reference frame and a forward-looking frame. CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: This study introduces a fresh research direction for potential investigations into the origins and progression of nuclear threats as a unique area of focus in the analysis of Eastern European media reporting during times of conflict.
