Why Hezbollah is threatened by a stable Syria

As long as Syria remains secure and stable, the corridor from Tehran to Beirut will remain severed—an existential threat to Hezbollah’s strategic depth

Why Hezbollah is threatened by a stable Syria

A few days after Iranian officials rejected the Lebanese government’s decision to disarm Hezbollah, Ali Larijani, Secretary of Iran’s Supreme National Security Council, arrived in Beirut. During his visit, he publicly affirmed Iran’s respect for Lebanon’s sovereignty and the decisions of its national institutions. However, events on the ground soon told a different story.

Just hours after Larijani’s departure, Hezbollah’s Deputy Secretary-General, Naim Qassem, accused the Lebanese government of serving Israeli interests and threatened to launch a “Karbala-like battle” in opposition to the disarmament decision, declaring that “there can be no life in Lebanon if the government dares confront the party.”

Stark reminder

In an interview with Asharq Al-Awsat, Prime Minister Nawaf Salam responded to Qassem’s threats, reminding the public that Hezbollah and the Amal Movement had previously agreed—during their participation in Prime Minister Najib Mikati’s government—to a cessation of hostilities last November. That agreement stipulated that “no party or political faction is authorised to bear arms in Lebanon.”

It is worth recalling that Mikati had tweeted at the time— minutes after the agreement became public—that he had reviewed its terms only once they had already been endorsed by both Nabih Berri and Hezbollah. In his post dated 26 November 2024, Mikati wrote: “I reviewed this understanding, which outlines a roadmap for a ceasefire, only this evening.”

Hezbollah can declare war on Lebanon and accuse the government of treason; accusations and threats have long been its chief means of political engagement. It can also provoke civil strife or clash with the Lebanese state and its military institutions. But the pressing question remains: what comes next?

Today, Hezbollah, Iran, and, ironically, Israel find common cause in their shared desire to destabilise Syria

One option is to integrate Hezbollah into Lebanon's national framework, although this remains a formidable challenge. Despite its local support, Hezbollah has never been Lebanese in the sense that it remained subservient to Iran and its diktats. If its cause were genuinely national, it would not have monopolised resistance efforts or confined them to its own ranks and weaponry.

Common cause

Over the past two years, Israel has dealt Hezbollah a string of hefty blows, and the group today is now busy licking its wounds. Today, Hezbollah, Iran, and, ironically, Israel find common cause in their shared desire to destabilise Syria.

Many observers believe that a stable Syrian state is essential to blocking a renewed surge of Iranian influence in the region. So, clearly, Tehran seeks to undermine said state, instructing its regional proxies to do the same. However, Israel also doesn't want to see a stable and strong Syria and prefers it descend into chaos and weakness.

It is no accident that Larijani's plane avoided Syrian airspace on its way to Beirut. As long as Syria remains secure and stable, the corridor from Tehran to Beirut will remain severed—an existential threat to Hezbollah's strategic depth.
