The October 7, 2023, and the subsequent war in Gaza have constituted not merely a military arena, but a battlefield of competing discourses over meaning, legitimacy, and the future of Palestine's political geography. This research aims to conduct a geopolitical analysis of the rivalry between Israeli security discourse and Palestinian sovereignty discourse in the post-October 7 order. The data consist of two landmark articles from the Carnegie Endowment for International Peace, representing the two dominant discourses, selected through purposive sampling. Employing a combined theoretical framework of Laclau and Mouffe's discourse analysis and critical geopolitics, the data have been analyzed.

The October 7 event ruptured the central signifier of "Israeli security," weakening deterrence, intelligence superiority, and conflict management. Conversely, Palestinian sovereignty discourse forges a new chain of equivalence around "Palestinian national sovereignty" by foregrounding ending occupation, territorial integrity, and political legitimacy. This confrontation is a hegemonic struggle over fundamental political ontology- "security" versus "the right to life and sovereignty"- a struggle over defining "life" and "political space." This study illuminates discourse's role in consolidating structural violence and foreclosing peace in Middle Eastern conflicts.
