Israel targets Lebanon's roads, bridges to isolate south for buffer zone: analysts

Since last Wednesday, the Israeli army has continued targeting the network of roads and bridges that link Lebanon to its south. In addition to pressuring the Lebanese government to make concessions, the Israeli army claimed that targeting the Qasmiyeh bridge and other bridges is intended to prevent the transfer of military supplies to southern Lebanon. However, military experts questioned this justification, noting that Israeli aircraft maintain intense air dominance over the routes leading to the south, which undermines the credibility of this claim. Sources believe that targeting infrastructure, especially bridges and roads, aims to isolate the southern region in preparation for occupying it and turning it into a "buffer zone." Return to buffer zone doctrine After the 1982 invasion, Israel maintained a buffer zone in southern Lebanon for 15 years. It was meant to prevent attacks but instead created local resistance and required constant military presence, ending with a unilateral Israeli withdrawal in 2000. In the 2006 Lebanon War, Israel avoided re-occupying Lebanon, relying instead on air power and UN peacekeepers. Now, in 2026, Israel is returning to buffer zone thinking. Current discussions of a 10-15 km buffer zone show that Israel is returning to a doctrine it once abandoned as distancing itself from its enemy is more important than before. Ground combat challenges On the southern front, the Israeli army has been facing major difficulties in advancing and consolidating its positions since March 2. Hezbollah in Lebanon targeted Israeli troops at dozens of locations, carrying out strikes against concentrations of soldiers and vehicles in different border villages using rockets and artillery shells. Operations extended beyond the border line, where Hezbollah support units targeted military positions and fixed barracks, as well as newly established sites. Strikes repeatedly hit the Avivim barracks, as well as Ramot Naftali, Branit, Hounin, Nahal Gershom base, and the Meron Air Surveillance Base. Tactical developments A notable development was the use of explosive drones similar to tactics used in Ukraine. On Friday, armed drones were used to strike a rear-area position on the Israeli side. This was considered the second major tactical surprise to enter the battlefield after the previous confrontation in 2024 during the "66-day battle." Both Hezbollah and the Israeli army also carried out psychological and media operations associated with the ground maneuver, including threats, intimidation, low-altitude aircraft flights, and air raids conducted at night or at dawn. Linked fronts Israeli attacks on Iran and the entry of Iranian missiles targeting Israeli troop concentrations and fortifications around the town of Khiam suggest that the linkage of fronts—from southern Lebanon to Iraq and Iran—indicates that the Khatam al-Anbiya headquarters in Iran is directing a confrontation against Israeli destabilization and US military presence across a theater stretching from the eastern Mediterranean to the Gulf. Overall assessment The ongoing confrontation since March 2 reveals a gap between Israeli rhetoric and action. Despite statements about deploying three full military divisions, these forces rely heavily on air strikes to flush out Hezbollah fighters positioned inside villages and in the surrounding wooded terrain. The conflict shows no signs of abating as Israel's ground operation faces stiff resistance and the broader regional war with Iran continues.
