Lebanon on the Brink of Internal Collapse
Jerusalem Africa Desk ·
Lebanon has long been a country with deep-seated sectarian divisions, and the current situation is a culmination of years of political and economic instability. The country has been without a functioning government for months, and the economy is on the verge of collapse. The internal power struggle has been exacerbated by the presence of Hezbollah, a Shia militant group backed by Iran, which has significant influence over the country's politics and military.
Lebanon’s Internal Stability Under Pressure as Hezbollah Standoff and Displacement Deepen Divisions
Lebanon is not in institutional collapse, but a convergence of mass displacement, renewed economic contraction, unresolved fighting in the south and a stalled effort to bring Hezbollah’s weapons under state control is placing exceptional pressure on the country’s political and social order.
Lebanon is confronting one of the most consequential tests of its internal stability since the end of its civil war.
The immediate threat is not simply another period of political paralysis. The country now faces several crises simultaneously: hundreds of thousands of people remain displaced, Israeli forces retain positions in parts of southern Lebanon, Hezbollah continues to resist full disarmament while Israeli troops remain on Lebanese territory, and the economy has returned to contraction after showing signs of recovery in 2025.
These pressures are interacting with Lebanon’s long-standing sectarian and political divisions.
That does not mean renewed civil war is inevitable. But it does mean that the mechanisms that traditionally contained disputes between Lebanon’s communities are being tested at the same time that the state is attempting to redefine the balance of military power between itself and Hezbollah.
Lebanon Has a Government — but State Authority Remains Contested
One important distinction from previous periods of Lebanese crisis is that the country is no longer operating without functioning national institutions.
President Joseph Aoun took office in January 2025, and the government led by Prime Minister Nawaf Salam subsequently won a parliamentary confidence vote with the support of 95 members of Lebanon’s 128-seat legislature.
The government committed itself to financial reforms, negotiations with the International Monetary Fund and a stronger role for state institutions.
The core institutional problem is therefore different.
Lebanon has a government. What remains unresolved is whether that government can establish an effective monopoly over national security policy and armed force.
That question centres overwhelmingly on Hezbollah.
The Iran-backed armed movement has for decades combined political representation with an independent military structure. The renewed war with Israel in 2026 sharply intensified the domestic debate over whether that arrangement can continue.
Earlier this year, the Aoun-Salam administration banned Hezbollah’s military wing and sought to move the country toward negotiations intended to reduce hostilities with Israel. Hezbollah rejected key elements of that approach.

Hezbollah’s Weapons Have Become the Central Political Fault Line
The disagreement over Hezbollah’s arsenal is no longer an abstract constitutional debate.
Under a U.S.-brokered framework agreed by Israel and Lebanon, Israeli forces are supposed to withdraw progressively as Lebanese authorities disarm Hezbollah and deploy state forces across the south.
By September, implementation had stalled.
Hezbollah has refused full disarmament while Israeli forces remain on Lebanese territory, while Israel has said its withdrawal is conditional on Hezbollah being disarmed.
This creates a circular security problem.
Hezbollah cites Israel’s military presence as a reason to retain its weapons. Israel cites Hezbollah’s weapons as a reason to maintain its forces.
The Lebanese government, meanwhile, is under domestic and international pressure to extend state authority without triggering armed confrontation with an organization that remains deeply embedded in parts of Lebanese society and politics.
The Lebanese Armed Forces therefore face a task that is political as much as military.
A forced confrontation with Hezbollah would carry serious internal risks. But indefinite failure to implement the disarmament framework could also weaken confidence in the state and complicate any Israeli withdrawal.
This is the central internal-security equation confronting Lebanon.
Displacement Is Placing Pressure on Lebanon’s Communal Balance
The social consequences of the conflict are equally important.
At the height of the renewed war earlier in 2026, more than one million people were displaced, many from predominantly Shi’ite communities in southern Lebanon and Beirut’s southern suburbs.
Their movement into Christian, Druze and other areas generated episodes of communal tension, including disputes over accommodation, local screening procedures and fears that displaced residents could themselves become targets of Israeli strikes.
The situation has improved substantially from the peak of the fighting, but displacement remains large.
As of 15 September, the International Organization for Migration recorded 341,228 internally displaced people in Lebanon.
At the same time, 864,680 people who had previously been displaced had begun returning to their communities.
Those numbers reveal two trends simultaneously.
Large-scale return is under way, which reduces some of the pressure on host communities. But hundreds of thousands of Lebanese remain unable or unwilling to return permanently, meaning displacement continues to affect housing, employment, municipal services and relations between communities.
This is why the earlier claim of a broad “demographic shift” needs qualification.
Lebanon is experiencing major wartime population movement, but the available data does not establish that the country’s permanent sectarian demographic structure has already been fundamentally transformed.
Sectarian Tensions Are Real — but Civil War Should Not Be Treated as a Forecast
The risk of communal violence cannot be dismissed.
During the spring of 2026, Lebanese politicians, former combatants and civil-society figures described rising distrust between Hezbollah’s largely Shi’ite constituency and communities that blamed the organization for drawing Lebanon into the wider regional war.
Reports documented physical confrontations, inflammatory political rhetoric and heightened suspicion toward displaced residents.
For Lebanese who lived through the 1975–1990 civil war, these developments have produced uncomfortable historical parallels.
But parallels are not predictions.
Lebanon today does not simply reproduce the political and military environment of 1975.
State institutions continue to function, the Lebanese Armed Forces remain nationally deployed, and political factions have strong incentives to avoid a conflict whose costs would be enormous.
The more defensible assessment is therefore that the risk environment for localized communal violence has increased, particularly if displacement becomes prolonged or if the dispute over Hezbollah’s weapons shifts from political negotiation to coercion.
That is a materially different conclusion from saying Lebanon is inevitably moving toward another civil war.
The Economic Crisis Has Returned to the Centre of the Security Equation
Lebanon’s internal stability cannot be separated from its economy.
The country had begun showing signs of recovery in 2025, with the World Bank estimating real GDP growth of 4.2%.
That momentum was reversed by renewed fighting in 2026.
The World Bank now projects the Lebanese economy to contract by 6.4% in 2026, citing destruction, displacement, disruption to supply chains and damage to tourism and domestic demand.
This setback comes on top of a financial collapse that began in 2019.
Lebanese banks restricted depositors’ access to savings, the currency lost more than 90% of its value, and the country eventually defaulted on its sovereign debt.
In August 2026, the International Monetary Fund welcomed amendments to Lebanon’s bank-resolution legislation as an important reform step, while warning that implementation and additional financial reforms remain necessary.
That distinction matters when assessing the possibility of “collapse.”
Lebanon is not starting from a healthy economic base.
The country entered the latest war with financial institutions already severely weakened. A prolonged reconstruction burden combined with persistent displacement and political instability could therefore have disproportionate effects on public services, employment and state capacity.
Southern Lebanon Faces Another Institutional Transition
A further source of uncertainty is the future of the United Nations Interim Force in Lebanon.
UNIFIL is scheduled to begin withdrawing at the end of 2026 after nearly five decades in southern Lebanon.
Its departure raises questions over who will perform some of its monitoring, liaison, humanitarian-access and stabilization functions in areas affected by the conflict.
European and Arab military officials met in Paris in September to examine Lebanon’s defence requirements and possible arrangements following UNIFIL’s departure.
Discussions have included additional international support for the Lebanese Armed Forces in training, equipment, intelligence and institutional capacity.
This transition could become one of the most important security developments of 2027.
If Lebanese forces are able to expand their presence while Israeli troops withdraw and Hezbollah’s military infrastructure is reduced through an agreed mechanism, the state could emerge stronger.
If those processes stall simultaneously, southern Lebanon could instead face a security vacuum in which several armed actors retain competing claims to authority.
Iran Remains Important, but Lebanon’s Crisis Is Not Simply an Iranian Proxy Issue
Iran remains a central external actor because of its long-standing relationship with Hezbollah.
But reducing Lebanon’s internal crisis solely to Iranian influence would obscure the domestic factors driving instability.
The dispute over Hezbollah is also a Lebanese dispute over sovereignty, deterrence, representation and the balance of power between communities.
Shi’ite support for Hezbollah cannot be assumed to be uniform, just as opposition to the organization spans several political and sectarian constituencies with different motivations.
External actors — including Iran, Israel, the United States, France and Arab governments — influence the environment in which these debates occur.
They do not eliminate Lebanon’s own political agency.

Strategic Assessment: The Test Is Whether the State Can Expand Without Triggering Confrontation
Lebanon’s immediate danger is not that state institutions will disappear overnight.
The more significant risk is progressive fragmentation of authority if three unresolved problems reinforce one another: prolonged displacement, failure to resolve Hezbollah’s armed status and continued territorial confrontation in the south.
At the same time, there are stabilizing indicators that should not be ignored.
Lebanon has a functioning presidency and government, parliament has moved forward on important banking reforms, hundreds of thousands of displaced people have returned, and international actors are discussing how to strengthen the Lebanese Armed Forces.
For Jerusalem Africa, the indicators worth watching are concrete rather than rhetorical:
The pace of displaced-person returns.
Implementation of the Hezbollah disarmament framework.
Deployment of Lebanese forces in southern Lebanon.
The timetable for Israeli withdrawal.
The transition following UNIFIL’s departure.
Progress on banking and reconstruction reforms.
Lebanon is under severe pressure, but “collapse” is not yet the analytical conclusion. The decisive question is whether the state can convert the current crisis into greater institutional authority — or whether unresolved military and sectarian competition will continue to erode it.
