Using a qualitative approach with a case study method, this study applies the theory of Security Dilemma by Robert Jervis and the concept of Interdependence by Joseph Nye and Robert Keohane. The results of the study show that the placement of THAAD triggers political and security tensions, including informal economic sanctions from China that have an impact on South Korea's tourism, investment, and entertainment sectors. However, high economic interdependence prevented a complete disconnection, with normalization achieved through the Three No's Policy. This study confirms that a country's defense policy has far-reaching consequences for diplomatic relations and regional stability.</p> Ahmad Naufaldi Ali Musa Harahap Sofi Mubarok Rudi Candra Copyright (c) 2025 Ahmad Naufaldi, Ali Musa Harahap , Sofi Mubarok , Rudi Candra 2026-01-18 2026-01-18 8 2 https://ejournal.unida.gontor.ac.id/index.php/mediasi/article/view/14463 <p>This article discussed Indonesia's diplomatic strategy in voicing Palestinian independence between 2019 and 2024.
