Since March 2026, Israel’s military aggression into Lebanese territory has become a manifestation of a far more ambitious shift in Tel Aviv’s security doctrine. The operation, which began following the assassination of Iran’s supreme leader in “Operation Epic Fury,” has developed into a large-scale ground invasion involving the mobilization of hundreds of thousands of personnel,  a figure that reflects Israel’s absolute priority to reorganize the regional map.

 

Under the command of the most right-wing cabinet in its history, Tel Aviv no longer hides behind narrow defensive rhetoric. The deployment of ground forces that began on March 16, 2026, openly targets control of territory up to the Litani River, which covers around 10 percent of Lebanon’s total land area. With the massive destruction of civilian infrastructure, including the demolition of five main bridges over the Litani River, Israel is effectively cutting off the geographic lifeline of southern Lebanon from the rest of the country.

 

The speed of Israeli troop movements on the ground in early 2026 shows highly mature logistical and intelligence preparation, far exceeding the efficiency of similar operations in previous years. The main focus of the military at present is to create new facts on the ground, or a fait accompli, that cannot be renegotiated through international diplomacy. This effort includes the mass expulsion of nearly one million Lebanese citizens, around 20 percent of the national population, who are now prohibited from returning to their villages in the south.

 

The ultimate goal of this campaign no longer appears to be merely a temporary ceasefire, but a long-term occupation wrapped in the term “security buffer zone.” However, behind the military calculation, in my view, there are shadows of old ideology that have now found renewed political momentum in the corridors of Israeli power. The big question now is no longer when this attack will end, but whether this is the initial step of the large “Greater Israel” project that has long been considered merely a fantasy of the extreme right wing.

 

Comparing the 2026 invasion with the “Operation Peace for Galilee” in 1982 shows a sharp contrast in the evolution of Israel’s strategy. In 1982, Israel’s main objective under Ariel Sharon was political in nature; Tel Aviv sought to engineer politics by installing a pro-Israel government in Beirut through an alliance with the Maronite Christian group led by Bashir Gemayel. The ambition at that time was a Lebanon that would become an official peace partner, although this strategy ultimately collapsed after Gemayel’s assassination and dragged Israel into an 18-year occupation.

 

In contrast, the 2026 war is no longer wrapped in a similar “political engineering” approach and has shifted fully to “physical and territorial domination.” Israel is no longer preoccupied with seeking local allies to manage Lebanon. Instead, Israel is applying what can be called the “Gaza Model” in southern Lebanon. This model involves the systematic destruction of all villages and infrastructure so that the area cannot be reinhabited by its original population. This is a spatial control tactic that is more brutal than what was seen in the 1980s, where the main objective is the permanent clearing of the area from potential threats.

 

This difference in methodology is also visible in the control of strategic points such as Mount Hermon and the Nabatieh area. If in the past territorial control was seen as a temporary bargaining position, now every inch of land occupied is accompanied by the construction of permanent fortifications and the destruction of civilian land registration records. Israel seems to have learned from the failure of 1982 that controlling Lebanese politics is impossible, so the choice now is to control its geography absolutely.

 

The scale of military deployment in 2026 is also much larger, with the involvement of reserve forces reaching 643,000 personnel to ensure control on multiple fronts simultaneously. Unmatched air dominance allows the Israeli military to destroy enemy communication and logistics centers with a high level of precision, minimizing risky ground contact as occurred in the past. This strategy reflects a new orientation: security is no longer achieved through peace agreements with weak neighbors, but through the creation of empty spaces under the control of weapons.

 

The core of global suspicion regarding Israel’s ambition lies in the concept of “The Greater Israel” or Eretz Yisrael HaShlema. Historically and religiously, this concept refers to the promised land in biblical texts, whose boundaries include southern Lebanon. The broad definition from Genesis 15:18, which mentions territory from the River of Egypt to the Euphrates River, automatically places all of Lebanon within the ideal map of Jewish expansionism. Even in the division of the ancient tribes of Israel, southern Lebanon was considered the inheritance of the tribes of Asher and Naphtali.

 

What was once considered a marginal aspiration of messianic groups has now transformed into a policy openly voiced by high-ranking government officials. Finance Minister Bezalel Smotrich has definitively stated that Israel’s new international boundary must be at the Litani River. This statement is not merely rhetoric for domestic political consumption, but an operational guideline being implemented on the ground. Smotrich views this boundary change as a “new reality” that must be accepted by the international community after the conflict.

 

Civil movements such as Uri Tzafon, which emerged in 2024, provide a practical dimension to this theological ambition. This group aggressively campaigns for the settlement of Jewish civilians in Lebanese territories successfully controlled by the military. The appearance of housing advertisements with views of snow-covered mountains in areas that are legally still part of Lebanese sovereignty indicates an effort to replicate the settlement model in the West Bank in southern Lebanon. For adherents of Greater Israel, the Litani River is not merely a military defensive line, but a religious boundary that must be restored.

 

What is shown by the Israeli military on the ground further strengthens the annexation thesis. The total destruction of villages and the prohibition on the return of Lebanese civilians create a demographic vacuum that becomes a prerequisite for the entry of new settlers. The use of the term “historical correction” by settlement activists to describe the occupation in southern Lebanon indicates that the motivation for this aggression goes far beyond merely weakening Hezbollah; it is an effort to redesign Israel’s national geography in accordance with their eschatological narrative.

 

The collapse of the Assad regime in Syria at the end of 2024 has created a power vacuum that Israel has utilized to strengthen its dominance. With the existence of a new security coordination mechanism between the Syrian transitional government, the United States, and Israel through the “Joint Fusion Mechanism,” Tel Aviv now has operational freedom on the northern front without significant disturbance from Damascus. This is the foundation of what is referred to as Pax Israelica, a regional order in which security is fully defined by Israeli military power.

 

Lebanon is currently on the verge of total state failure. With the burden of one million internally displaced persons and the postponement of parliamentary elections until 2028, the central authority in Beirut is losing control over its sovereign territory. This condition is highly ideal for Israel to establish de facto annexation in the south. The most likely projection is that Israel will maintain military control over the area south of the Litani for an indefinite period, while gradually building civilian infrastructure that will permanently change the status of the territory.

 

Diplomatic efforts to achieve a permanent ceasefire appear deadlocked because Israel proposes conditions that touch the core of Lebanese sovereignty, such as control over airports and ports to prevent rearmament. Without significant international pressure, especially from the United States under the Trump administration, which tends to give full freedom to Netanyahu’s strategy, the occupation of southern Lebanon will become a permanent feature on the new map of the Middle East. Lebanon is forced to enter this new regional order as a security protectorate state, or face the risk of further internal fragmentation that could trigger civil war.

 

In short, the attack on Lebanon in 2026 is the culmination of the convergence between modern security needs and ancient expansionist ambitions. The Litani River is no longer merely a geographic name, but a monument to the collapse of Lebanese sovereignty and the rise of Greater Israel ambition. Amid the silence of the world’s response, border lines in the Levant are being redrawn with fire and concrete, creating new historical wounds that will haunt regional stability for decades to come. Southern Lebanon, in the vision of Pax Israelica, appears to have been prepared to become a “new Northern Galilee,” completing the territorial mosaic of a nation that feels it has a divine right to continue expanding.
