South Lebanon
South Lebanon is a critical security theater bordering northern Israel, serving as the primary stronghold for Hezbollah's military infrastructure and a focal point of the direct kinetic confrontation between Israel and the Iranian regime.
South Lebanon has long functioned as the primary launchpad for aggression against Israel's northern communities. Dominated by Hezbollah's military presence, the region is characterized by a dense network of fortified villages, underground tunnel complexes, and rocket launch sites embedded within civilian infrastructure. Since early 2026, the theater has evolved from a zone of proxy friction into a direct battlefield involving the Islamic Revolutionary Guard Corps (IRGC). Recent developments have seen Iran attempt to establish a new 'deterrent equation,' claiming that any Israeli strike on Lebanese soil will trigger direct Iranian missile fire at Israel. In response, the IDF has intensified its operations to dismantle Hezbollah's regional units—specifically the Aziz, Nasser, and Bader units—and neutralize weapons production facilities. The strategic importance of South Lebanon lies in its proximity to the Galilee, making its demilitarization a core requirement for the safe return of displaced residents. While Israel recently paused direct strikes on Iranian territory at the request of the Trump administration, senior officials have emphasized that operations in South Lebanon will continue at full force. The IDF continues to target high-value infrastructure in areas such as Tyre, Zifta, and Saksakiya to prevent the re-establishment of Hezbollah's offensive capabilities near the border. Despite reports of a partial truce or ceasefire involving Iran, Hezbollah has continued to carry out drone and missile attacks against IDF positions, such as near Naqoura, highlighting the fragile and volatile nature of the current security arrangements in the sector.
