Based on Laclau and Mouffe's Discourse Theory, this study provides semantic systems of JCPOA-related discourse in the form of "Official / state" and "Conservative" discourse and their discursive battles, while Foregrounding / Backgrounding in field of language and media discourses through Dichotomous Paradigms. Contents of six media outlets were assessed in Persian calendar 1394 till 14th Aban1397. The field of research is divided to Micro and Macro levels. In Macro, Discourses are analyzed on base of Laclau and Moufeh's Discourse Theory. In Micro, Text Analysis is held on base of Dichotomy as Seperated semiosis system. Seven dichotomous were recognized. The articulation of both discourses in media content engross of dichotomized representation of "foregrounding self" and "backgrounding the Other". Official/State discourse takes "sanction lift" moment along with "good deal / bad deal" and also Foregrounding of "Transparency / Rent". This discourse tries to articulate its meaning system through Empty Signifiers. Conservative discourse defines Ideological discursive moments and focus its Nodal Points on Antagonistic relations in order to break its competitor's hegemonic domination of "Constructive interaction" and "Interaction / Confrontation. Both discourse employ signifier in rival's Field of Discursivity, for creating dichotomy, as well as employing floating signifiers after threat of JCPOA.
