Last Card is Rarely Lucky: Lebanon’s Next War of Survival

But deterrence depends not only on capability; it depends on credibility, cost to adversaries and the element of surprise. In 2006, Hezbollah shocked Israel by striking a naval vessel few believed it could target. In previous years, it externalized certain reprisals to attacks outside of Lebanon without claiming them outright, cultivating ambiguity. This time, its response was calibrated to satisfy pride but not to alter the balance. It neither deterred nor de-escalated. It simply triggered.

That miscalculation has domestic consequences more severe than the military ones. Hezbollah’s social base in the south and the Beqaa Valley has long endured devastation in exchange for the promise of protection and dignity. This time, what they received instead was renewed displacement without tangible strategic gain. The implicit social contract—sacrifice for security—has snapped for Hezbollah’s support base.

Power Recalculates

The most telling development is political. Amal, Hezbollah’s longtime partner in what was dubbed the “Shia duo,” has backed an unprecedented government move to deem the party’s weapons illegal. That would have been unthinkable weeks ago. While not necessarily indicative of a wholesale split, that hedging by an entrenched ally signals a shifting cost-benefit analysis, that Hezbollah’s hand appears short on cards to play.

But a weakened Hezbollah does not mean a stronger state. On the contrary, the manner in which disarmament has unfolded—with parallel efforts from the state and Israel. While Israel’s consistent violations of the ceasefire fed into Hezbollah’s resistance narrative, the Lebanese state’s gradual efforts were bearing fruit while managing fragile social tensions alongside it.

Yet, while the Lebanese state began collecting weapons from Hezbollah, it was unable to articulate a credible national defence strategy that reassured the south it would not be abandoned. Arms were surrendered when discovered, not as part of a negotiated, face-saving transition to state monopoly. And what has emerged from the disarmament process has produced the worst of both worlds: a humiliated militia and an army unprepared or unwilling to defend its borders.

Here lies the structural dilemma. Hezbollah’s arms distorted Lebanese sovereignty and subjected Lebanon to the political interests of Iran. But they also functioned—however problematically—as a form of deterrence against ground incursions. Lebanon’s army itself has now retreated from the border areas. While this move may be tactical, its flies in the face of an October edict by the President who directed the Army to deter any Israeli incursion. Today, Israel has widened its territorial gains in the South and looks set to expand its ‘buffer zone’ once again.  As Hezbollah’s deterrent evaporates without being replaced by a capable, politically empowered national army, Lebanon becomes an open field and Israel currently holds escalation dominance.

A buffer zone on Lebanese soil, reminiscent of the 1980s and 1990s, is almost undoubtedly what will follow. Occupation, history reminds us, is what gave birth to Hezbollah in the first place. Movements forged in resistance rarely disappear; they mutate. And if the state confronts Hezbollah militarily without the capacity to defend the border, internal strife could resurrect the very legitimacy the party is losing.

Compounding the problem is external constraint. The Lebanese Armed Forces are heavily reliant on U.S. support. Washington’s assistance has been calibrated to strengthen the army as an institution while limiting its ability to parry Israeli aggression. Indeed, ensuring Israel’s qualitative military advantage is enshrined in U.S. law. It is thus impossible for the Lebanese army to simultaneously disarm Hezbollah and deter Israeli incursions without political space and matériel it does not currently possess.

No Clean Exit

Lebanon now faces a narrow corridor. Full surrender—political and strategic—invites fragmentation. Total confrontation with Hezbollah risks civil conflict. Nostalgia for militia-led deterrence is equally untenable.

The only viable path is procedural, not theatrical. Disarmament must be embedded in a transparent national process and defence doctrine endorsed across sectarian lines. The army must visibly assume responsibility for the south, with some form of international guarantees that Israeli forces will not exploit the transition to alter facts on the ground. Confidence-building measures—mutual withdrawals, clear demarcations, robust monitoring—are not concessions; they are prerequisites for internal consolidation and will require diplomatic heft.

Hezbollah, for its part, must confront a reality it long denied. It cannot claim to defend Lebanon while subordinating Lebanese stability to regional calculations,  Its political legitimacy, if it is to survive, must be decoupled from autonomous arms and re-rooted in civilian competition.

Israel, meanwhile, should recall that maximalist security doctrines often produce their opposite. Expanding territorial control may yield short-term tactical depth, but it historically generates decentralized resistance. One need not romanticize Hezbollah to recognize that humiliation and vacuum are fertile soil for militancy.

The tragedy is that Lebanon’s choices are constrained precisely because Hezbollah overplayed its hand. By acting in a way that neither deterred nor defended Lebanon, the party exposed the fiction that it could calibrate regional confrontation without imposing existential costs on its own society. It has left the state scrambling to assert sovereignty amid bombardment, rather than consolidating it in calm.

Weakness Is Not Destiny

But as Lebanon negotiates from weakness, we should recall that weakness is not destiny. States are rebuilt not through grand gestures but through institutions that command cross-sectarian consent. That requires painful trade-offs: Hezbollah relinquishing its arms in a structured process; the army reforming itself and stepping into a genuinely national role; and international relations geared towards guarantees that exercising sovereignty will not be punished.

In this context, peace is a far-flung illusion. But relative stability, if it comes, will not be the product of surrender or swagger. It will emerge from a process that replaces militia deterrence with state legitimacy and replaces episodic ceasefires with enforceable arrangements. Without that architecture, disarm one group and others will rise. Chase one militia and several more will proliferate.

So today Lebanon holds its last card, and they are nearly blank. What it writes on them—procedure or pride, institutions or improvisation—will determine whether this war becomes an inflection point or merely a prelude. The cost of getting it wrong is no longer theoretical. It is measured in the homes already lost and the ones that will not be rebuilt if fragmentation, not peace, becomes the final inheritance.
