Hezbollah's 2023 War Choice Reshaped Lebanon Forever

The attack on Israel on October 7, 2023, did more than ignite a bloody conflict in Gaza. It reshaped the political reality of Lebanon forever. Just one day later, Hezbollah chose to enter the war as a supporter of Palestinian causes. Analysts say this single move altered the balance of power inside the country and set off a chain reaction that no one could stop.

Experts believe the group misread how deep Israel's intelligence reach had become before the fighting started. That miscalculation led directly to the devastating pager explosions in September 2024, which killed many Hezbollah members. It also ended with the assassination of Secretary-General Hassan Nasrallah and much of the leadership team. Nicholas Blanford, a senior fellow at the Atlantic Council, told Al Jazeera that Hezbollah got caught in a vortex. That trap resulted in the loss of their top commanders and an invasion of southern Lebanon. The blow to their popularity was severe enough to galvanize Joseph Aoun into becoming president and helped form a new government that took a much harder line against the group.

Hezbollah has never recovered its former political strength. While some critics claim defeat is not on the table, analysts agree the group is no longer the military or political hegemon it once was inside Lebanon. Before October 7, Hezbollah stood as the strongest actor in the country. It represented the large Shia community and counted Iran among its backers. Its influence stretched far beyond Lebanon's borders. The group helped the al-Assad regime retake territory in Syria from anti-government forces. It also maintained strong ties with allies in Iraq and Yemen.

Inside Lebanon, Hezbollah held key electoral power. It could elect governments or bring them down at will. In 2019, the group used its supporters to beat back protesters calling for reform of the sectarian system. That move cemented its role as a central player since the civil war ended in 1990. Months before October 2023, confidence within Hezbollah was obvious. Blanford pointed to a military parade in south Lebanon and tents erected on the Shebaa Farms, which Lebanon claims Israel occupies. At that time, Israel faced protests at home. Hassan Nasrallah gave speeches predicting Israel's imminent fall. Then came October 8, when Hezbollah joined the fight in what became known as the War of Support.

Jad Dilati, a political analyst from Nabatieh in southern Lebanon, told Al Jazeera that October 7 set in motion events Lebanon was not ready to handle. Hezbollah opened its support front on October 8 without any cabinet decision or governmental consensus. The group ignored the positions of residents in the south who were most affected and still suffer today. Dilati said Hezbollah moved from a position of strength it genuinely believed it held. But that belief blinded them to the risks ahead. They underestimated how deeply embedded Israel's intelligence operations had become. The result was a loss of control over their own borders and a fractured political landscape that continues to this day.

Most Southerners thought Hezbollah stood strong. They had spent years perfecting precision missiles and digging an elaborate tunnel network. Those missiles were claimed to be able to strike every building in Tel Aviv.

For the next 11 months, Israel and Hezbollah traded attacks. Israel hit Lebanon more than five times for every single attack from Hezbollah. Tens of thousands fled their homes in southern Lebanon and northern Israel.

But September 2024 changed everything. Israel unilaterally intensified its strikes. The carnage arrived quickly and heavily. Nearly 500 people died on September 23 alone. When Nasrallah seemed willing to accept a ceasefire, Lebanese officials told media reports that Israel ordered his assassination and the evacuation of Beirut's southern suburbs.

"When Nasrallah was amenable to a ceasefire, Israel was on the offensive and wasn't going to return to the previous status quo," Blanford said.

Israel invaded southern Lebanon in October 2024. It stayed inside Lebanese territory for more than two months after a ceasefire was agreed in November. Even with that agreement in place, Israel kept destroying homes and infrastructure in the south. The army refused to pull out of five locations on Lebanese soil. Next door in Syria, the fall of the al-Assad regime in December 2024 dealt another blow. Land routes for weapons and funding from Iran were disrupted.

Over the next 14 months, Israel violated the ceasefire more than 10,000 times. Then March 2026 brought a new escalation. Israel reintensified its war on Lebanon. Attacks followed after Hezbollah fired rockets at Israel for the first time in over a year. This was a response to ceasefire violations and the assassination of Iran's Supreme Leader Ayatollah Ali Khamenei, whom Hezbollah viewed as a religious and political leader.

Israel invaded Lebanon again and launched widespread attacks on the country. It has killed more than 9,000 people since 2024. More than 1.2 million people have been displaced. Entire regions of the country are now empty.

Hezbollah faces a legitimacy crisis unlike any before. Israel occupies large swathes of Lebanese territory. Some points stretch up to 10 kilometres from the border. Dozens of villages, once filled with agriculture and people, are now uninhabited piles of dust and rubble. Hundreds of thousands remain displaced.

This has devastated Lebanon. The World Bank says the economy contracted by more than 6 percent in 2026. After the 2024 conflict, the bank said Lebanon needed around $11bn for recovery and reconstruction. That figure is likely much higher now.

In past wars against Israel, such as in 2006, Hezbollah supported much of its community and supporters. Providing social welfare was key to maintaining popularity and belief among constituents. But since 2024, the Lebanese state, along with much of the international community, has worked to expand its own services. The state openly claims it is working to disarm Hezbollah despite group objections. This happens as part of a framework agreement with Israel.

"Hezbollah is in a legitimacy crisis that it has not faced before," Dilati said.

One veteran analyst offered a sober assessment of the shifting mood in southern Lebanon. He stated clearly that there is no total political rupture or complete realignment yet. Instead, many communities which supported the group for decades now feel abandoned. They believe Iran fought wars on their soil to serve foreign interests, not local needs. Consequently, these residents simply do not want more conflict.

Grumbles against Hezbollah are growing louder among the general population. Yet analysts note a stark reality that critics often ignore. The organization remains the most popular representative for Lebanon's Shia Muslims. Blanford explained this dynamic directly. He noted that Hezbollah provides essential services by and large. There is currently no political alternative available to the Shia community.

Several hundred thousand Shias were forced from their homes years ago. They now live in non-Shia areas where they often feel unwelcome. This situation breeds a deep sense of vulnerability. Naturally, this drives them toward Hezbollah as a form of communal protection. Whether that choice is right or wrong remains a matter of debate.

The group still maintains significant fighting capacity today. Critics sometimes call it a spent force, but foreign diplomats disagree. They argue that the organization's weakness has been greatly overstated by outside observers. Its future depends heavily on regional events, especially any US-Israeli war against Iran. However, the current status quo poses serious risks. The state negotiates with Israel while trying to extend its influence across Lebanese territory. Hezbollah must adapt to waning domestic support under these conditions. This environment could work directly against the group's long-term survival.

Blanford warned about a potential scenario of long occupation. People who lost their homes and villages face a difficult choice. Those displaced also lost orchards, banana plantations, tobacco fields, and everything else they owned. They may start to believe life was better before. This realization could cause them to turn against Hezbollah in the coming years.
