Lebanon’s war through a systems thinking lens

Lebanon is not simply caught in a war. It is operating within a system that makes escalation difficult to avoid and even harder to contain.

To understand Lebanon’s current volatility, it is necessary to move beyond isolated explanations and instead view the country as a complex system, where multiple forces interact to produce outcomes far more volatile than the sum of their parts. In moments of conflict, these interactions do not disappear; they intensify.

A “systems thinking” perspective, one which emphasizes interdependence, feedback loops, and emergent outcomes, helps clarify this complexity.

Prominent systems thinker Robert Jervis argues that a system exists when two conditions are met: its elements are linked such that a change to any one component reverberates across the whole, and the system exhibits characteristics distinct from those of its individual parts (emergent properties).

Under emergent properties, a system may be symmetric even if its elements are asymmetric, or unstable even when each component is stable. This non-linear relationship produces a core systems principle: outcomes cannot be predicted from separate actions, as interacting elements generate effects that cannot be understood in isolation. This principle undercuts any attempt to explain Lebanon’s past and present political trajectory through one variable alone.

A systems framework in Lebanon

Viewed through this lens, Lebanon’s political landscape appears less a collection of discrete problems than an interlocking set of dynamics that reinforce and reshape one another.

Consider the interaction between two foundational elements of Lebanon’s political structure: the post-Taif confessional system (element A) and the country’s dense network of external patronage relationships (element B).

 On its own, element A—a power-sharing formula that assigns top state positions and parliamentary seats by sect—can slow decision-making or encourage elite bargaining. Yet such systems are not inherently destabilizing. In other contexts, such as Northern Ireland, they have provided mechanisms for managing division. 

Element B, however—the long-standing ties between Lebanese parties and foreign powers such as France, the United States, Saudi Arabia, and Iran—introduces an additional layer of constraint.  When the two interact, these constraints reinforce existing frictions and a new systems dynamic emerges: periods of state paralysis. 

Domestic politics become entangled with regional bargaining, as internal decisions depend not only on agreement among Lebanese actors, but also on the alignment of external patrons whose interests must be accommodated. Under normal conditions, this results in delays and periods of governmental deadlock.

Under wartime conditions, it becomes more consequential: the Lebanese state faces growing difficulty in coordinating or advancing a unified response. As Israel continues its military operations in the south and strikes expand into central Beirut and across the country, the absence of a clear central coordinating authority can limit Lebanon’s ability to shape how the conflict evolves. Paralysis, in this context, is not merely political. It is operational.

The logic of strategic interdependence

This constraint on state decision-making highlights another systemic property central to Jervis’s framework: strategies depend on the strategies of others. No actor can choose a strategy based solely on its own preference, as the strategy’s success is determined by how other actors respond.

Lebanon’s domestic “strategy” is therefore shaped by those of Israel, the United States, and Iran. Nearly every key Lebanese actor is tied, either ideologically or materially, to an external patron. Hezbollah’s trajectory offers a clear example. Its current engagement in sustained exchanges with Israel, including large-scale rocket and drone fire into northern Israeli territory, reflects not only local calculations but its role within Iran’s broader regional posture. As Iran’s own confrontation with Israel intensifies, the Islamic Revolutionary Guard Corps (IRGC) elements embedded within Hezbollah’s command center have pushed for sustained escalation along the Lebanese front.

In this context, Hezbollah operates less as an isolated actor and more as a forward-operating node within a wider regional system. As Iran’s strategic environment shifts, Hezbollah’s behavior adjusts accordingly, tying Lebanon’s internal stability directly to the evolving dynamics of the war beyond its borders.

This pattern reflects another principle of systems thinking: the most important determinant shaping relations between two states often lies in each state’s relationships with third parties.  

Lebanon’s relationship with Syria has historically been filtered through each country’s alignment with Iran, with cross-border networks linking Hezbollah, Syria, and Iran facilitating Iranian support to Hezbollah as part of a broader “Shia crescent.”

The fall of the Assad regime, however, altered this configuration. Under the new leadership in Damascus under President al-Sharaa, Syria’s external alignment has shifted, with the United States emerging as a more prominent third-party influence shaping Syrian-Lebanese dynamics. This reorientation is reinforced by Washington’s growing engagement with the new Syrian leadership and its longstanding security ties to the Lebanese state.

Yet this transition remains incomplete. Hezbollah continues to operate within its established relationship with Iran, even as the Syrian state reorients. The result is not a clean realignment, but an overlapping system in which competing external linkages, U.S. and Iranian, simultaneously shape interactions between Lebanon and Syria.

Asymmetric dependencies and limited options

Asymmetric dependencies amplify these imbalances. A state’s bargaining power increases when it can turn to alternative partners, something Lebanon rarely has. 

This dynamic is particularly evident in its relationships with the United States and Saudi Arabia. The United States possesses a wide range of regional alternatives. It does not rely on Lebanon for strategic access (with bases in the Gulf, Jordan, Israel, and Cyprus), intelligence (with other regional hubs), or force projection (supported by the 5th Fleet and CENTCOM’s established presence). Saudi Arabia can likewise redirect financial and political support to other Arab states, such as Jordan, Egypt, and Iraq, or toward domestic priorities under Vision 2030. These asymmetries are further compounded under current wartime conditions.

 At present, the United States’ strategic focus is directed toward its confrontation with Iran. Saudi Arabia, similarly, is preoccupied with its own security concerns, including threats linked to regional escalation.

Lebanon, however, cannot replace either patron. Its banking system depends on U.S. dollar access, the Lebanese Armed Forces relies almost entirely on U.S. support, the economy depends heavily on Gulf remittances, and tourism often hinges on Gulf visitors. 

Unlike many small states, Lebanon lacks alternative anchors in the current war. Russia remains heavily engaged in Ukraine, China has little appetite to intervene in an active conflict, and Iran, though central, is itself directly involved and constrained by economic sanctions. European states, meanwhile, lack the cohesion and capacity to serve as effective substitutes.

 Lebanon therefore faces a moment of heightened need for external support, yet with few viable alternatives. As Israeli strikes expand and displacement accelerates, reliance on external actors deepens, even as those actors remain focused on their own strategic priorities. This imbalance narrows Lebanon’s room for maneuver at precisely the moment it is most exposed.

Threat-based unity and its limits

These constraints highlight another systems dynamic: the strongest force for temporary cohesion is a common enemy.

The 2006 war between Israel and Hezbollah offers a striking example. Before July 2006, Lebanon was deeply polarized, with sectarian tensions sharpening between the March 8 and March 14 camps as the country struggled to recalibrate after Syria’s 2005 withdrawal. With the onset of cross-border strikes and Israel’s ground offensive, Lebanese factions long critical of Hezbollah moved into temporary alignment and condemned Israel’s attacks. This was not an ideological unity. It was a threat-driven convergence. Once the war ended, unity collapsed. While powerful, a common enemy is never lasting. It stabilizes the system briefly but fails to alter its underlying structure.

The current war points to a more complex variation of this dynamic. Rather than producing broad alignment around a single narrative, it has generated competing interpretations of the threat itself. Although Israel’s aggressive military campaign has rendered it the immediate and most visible threat, many nevertheless still view Hezbollah’s actions as having drawn the country into a broader regional war.

In this context, the logic of threat-based unity could take on a different form: potential coordination among actors outside Hezbollah around the reassertion of state authority and a demand to disarm non-state armed groups.

The dynamics of system stability

A second layer of systems thinking, drawn from Donella Meadows’s Thinking in Systems, helps explain why Lebanon’s system often proves resistant to stabilization. Meadows identifies three core characteristics of effective systems: resilience, hierarchy, and self-organization. Lebanon exhibits imbalances across all three.

Resilience, a system’s ability to endure volatility, stems from the presence of feedback loops that restore a system following disturbances. A positive feedback loop amplifies change; a negative feedback loop stabilizes it.

Lebanon, however, is dominated by unchecked positive feedback loops. In the 2019 economic crisis, as the lira lost value and trust in the banking sector evaporated, people rushed to convert their savings to dollars. The spike in dollar demand further devalued the lira, which deepened panic and accelerated the collapse. Because Lebanon lacked a transparent banking sector, credible central bank reserves, and effective political decision-making, there were no balancing mechanisms to slow the spiral. The result was a catastrophic collapse—98% currency loss, triple-digit inflation, and widespread poverty.

The current war illustrates this dynamic in real time. Hezbollah’s initial strikes into northern Israel prompted a forceful Israeli response, which in turn triggered further escalation by Hezbollah. This cycle has intensified as Israel expanded its operations, moving from border exchanges to a broader campaign that includes ground activity in the south and sustained strikes on Dahiyeh and central Beirut. Each round of action reinforces the next, expanding both the geographic scope and intensity of the conflict.

Hierarchy and fragility

Meadows’s second pillar, hierarchy, points to another structural imbalance. Effective systems require multi-level structures: the overarching system coordinates its subsystems, which regulate themselves and serve the needs of the whole. Hierarchies fail when the larger system overcontrols (centralization) or a subsystem optimizes its own goals at the expense of overall performance (suboptimization).

Lebanon, however, has experienced extreme centralization since the early 1990s. Reconstruction concentrated investments, political power, and financial institutions in Beirut, leaving other regions with limited infrastructure and diminishing economic prospects. This concentration of power weakened Lebanon’s subsystems, causing them to stall rather than evolve. 

Hyper-centralization also creates systemic fragility: when one “node” fails, the entire system collapses. When the banking sector imploded in 2019, the entire country collapsed, because the hierarchy had over-optimized around a single node (Beirut). 

Lebanon therefore suffers from both suboptimization, Beirut growing at the country’s expense, and overcentralization, which leaves the entire system vulnerable to the failures of a single hub.

Self-organization and state erosion

Lebanon does, however, demonstrate strong self-organization, Meadows’ final systems property, which reflects a system’s ability to generate new structures, learn, and grow more complex.

As the state’s capacity for coordination is strained during the current war, humanitarian organizations and local community groups continue to build parallel networks for healthcare, shelter, and basic services.

These structures reflect high adaptive capacity but also perpetuate the state’s weakness. Hezbollah itself represents a form of highly developed self-organization: a non-state actor capable of exercising military authority independent of the Lebanese state. 

For Lebanon to strengthen its sovereignty, especially in matters of security, the state must build its capacity to deliver essential services during war and assert a monopoly over the use of force. Otherwise, the state’s ability to shape decisions over conflict and escalation will remain limited.

A system in war

Taken together, the systems frameworks offered by Jervis and Meadows help explain not only Lebanon’s persistent instability, but its behavior under active conflict. The current war does not represent a rupture in the system. It reveals its underlying dynamics under extreme stress.

The interaction between confessional structures, regional entanglements, and powerful self-organizing networks produces a political order defined by reinforcing loops rather than stabilizing ones. These loops do not simply intensify during war; they generate conflict and drive its escalation.

Without shifts in the underlying system—rebalancing political structures, rebuilding state capacity, and strengthening sovereignty—these patterns of volatility and paralysis are likely to persist, in war as in peace.
