Talking While Fighting: Inside the Pentagon's Unprecedented Israeli-Lebanese Military Talks — and Why They May Not Work

On the morning of May 29, 2026, military delegations from Israel and Lebanon sat across from each other inside the Pentagon for the first time in the history of the two nations' adversarial relationship. Under Secretary of War for Policy Elbridge Colby hosted what the Department of Defense described as "productive, military-to-military talks focused on building practical frameworks for regional security and stability" [1]. The meeting launched a security coordination track running parallel to State Department-led political negotiations scheduled for June 2-3 [2].

The talks represent a significant escalation of U.S. diplomatic involvement in a conflict that has defied resolution for decades. But they also unfold under conditions that test the limits of the format: Israeli troops were pushing deeper into southern Lebanon on the same day the delegations met in Washington [2], the ceasefire between the two sides has been violated repeatedly since its April 16 inception [3], and the central question — whether Lebanon can realistically disarm Hezbollah without fracturing its own state — remains unanswered.

What Happened at the Pentagon

The Pentagon readout was deliberately sparse. Colby's office confirmed that both delegations "engaged in productive" discussions on ceasefire enforcement, border stability, the timeline for Israeli withdrawal from southern Lebanon, and the role of the Lebanese Armed Forces (LAF) in containing Hezbollah [1]. No specific commitments were announced. The progress from these talks, according to the Pentagon statement, would "directly inform the Department of State-led political track" resuming the following week [1].

This framing — military talks as inputs to political negotiations, rather than as ends in themselves — mirrors the structure of prior U.S.-brokered regional agreements. The distinction matters because it signals that Washington views the security track as a confidence-building mechanism, not a standalone peace process [2].

The 45-day ceasefire extension agreed on May 15 provides the immediate diplomatic deadline. Both sides must demonstrate progress before the arrangement expires in late June [3]. Israeli officials have stated that their forces will remain inside southern Lebanon during the truce, conditioning withdrawal on the elimination of Hezbollah's threat to northern Israeli communities [3]. Hezbollah, for its part, has vowed to continue resistance until Israeli airstrikes stop and troops leave Lebanese territory [4].

The Lebanese Armed Forces: Caught Between Mandates

The LAF sits at the center of every proposal for stabilizing southern Lebanon, yet its capacity to fulfill that role has been contested for two decades.

Under UN Security Council Resolution 1701, adopted after the 2006 war, the area south of the Litani River was to be cleared of all armed actors other than the LAF and UNIFIL [5]. That mandate was never fully implemented. As the UN's own reporting acknowledges, "Lebanon has not extended effective control over southern Lebanon, as the UN Security Council called upon it to do in 1978, 2002, 2003, and 2006" [5].

The LAF's total active personnel number approximately 60,000 [6]. Following the November 2024 ceasefire, the army began deploying south of the Litani for the first time in years. By June 2025, 7,522 LAF personnel were stationed across 116 positions in the south, according to UN Secretary-General reporting [7]. That number has since risen to an estimated 8,500 [7].

In January 2026, the LAF commander declared the completion of "phase one" of a plan to bring all non-state weaponry under state control between the Litani and the Israeli border [8]. A second phase, extending state authority farther north, was outlined but has proceeded slowly amid continued Israeli operations and political resistance.

The question of whether the LAF operates independently of Hezbollah, or coexists with it in a carefully managed arrangement, remains one of the most sensitive in Lebanese politics. The two forces have historically maintained separate chains of command, but the practical reality on the ground — particularly before 2024 — involved what analysts have described as a pattern of "non-interference" in which the LAF did not actively challenge Hezbollah's military infrastructure south of the Litani [5].

$3 Billion in U.S. Aid: What Has It Bought?

Since 2006, the United States has invested more than $3 billion in military assistance to the LAF, part of a broader $5.5 billion foreign assistance package to Lebanon [9]. The aid has included equipment, training programs, and direct budget support.

Key allocations include a $120 million close air support package announced in 2017, $216 million in combined State and Defense Department grants in fiscal year 2020, $72 million rerouted to cover soldier and police wages as Lebanon's economic crisis deepened, and $95 million in Foreign Military Financing unfrozen in March 2025 [9][10][11]. The U.S. government has also facilitated $1.9 billion in active Foreign Military Sales cases with Lebanon [9].

Critics from multiple perspectives question the return on this investment. The Quincy Institute for Responsible Statecraft has noted that the United States effectively arms both sides of the Lebanon conflict — providing weapons to Israel for operations against Hezbollah while simultaneously funding the Lebanese military that has coexisted with the armed group [12]. Congressional skeptics, particularly those aligned with pro-Israel positions, have questioned whether U.S. aid strengthens the Lebanese state or effectively subsidizes a military that has not confronted Hezbollah [13].

Defenders of the aid program argue that the LAF represents the only viable institution capable of extending state authority in southern Lebanon and that cutting assistance would accelerate state collapse — an outcome that would benefit Hezbollah more than any alternative [9].

Hezbollah After Nasrallah: Diminished but Not Defeated

The military context for these talks is shaped by the most consequential period of Israeli operations against Hezbollah since 2006. In September 2024, Israel assassinated Hezbollah's secretary-general Hassan Nasrallah in a massive bombing that destroyed the group's main headquarters in Beirut [14]. His deputy, Hashem Safieddine, was also killed [14].

Israeli operations through the fall of 2024 led to the destruction of significant portions of Hezbollah's missile stockpile and military infrastructure in southern Lebanon. Sources familiar with the group's operations estimated that Hezbollah lost approximately 4,000 members during the conflict — more than ten times its losses during the 2006 war [14].

A ceasefire was signed on November 27, 2024, mandating a 60-day halt to hostilities, Israeli withdrawal from the south, and Hezbollah's retreat north of the Litani [15]. But the group has not accepted permanent disarmament. Naim Qassem, who succeeded Nasrallah as secretary-general, has stated plainly: "We will never abandon our weapons, nor will we relinquish them" [16].

UNIFIL and the LAF have discovered a rising number of weapons caches south of the Litani since the ceasefire — more than 100 by January 2025, over 225 by May 2025, and more than 360 by late 2025 [17][18]. These discoveries confirm the scale of Hezbollah's pre-war military infrastructure in the south.

Separately, reports from April 2026 indicate that Hezbollah has been acquiring weapons through Syria's black market, with warehouses in Damascus containing hundreds of Grad, Scud, and Katyusha rockets [19]. Syria's new administration under Ahmed al-Sharaa has reported thwarting multiple weapons trafficking schemes, including stockpiled IEDs, drones, and explosively formed penetrators [20].

UNIFIL's commander, however, has stated that the force has found "no evidence" of Hezbollah rearming south of the Litani specifically — drawing a geographic distinction between smuggling north of the river and the situation in the immediate border zone [21].

The Sovereignty Dilemma: Critics' Case Against the Talks

Lebanese Parliament Speaker Nabih Berri, who leads the Amal Movement — Hezbollah's closest parliamentary ally and the dominant political force among Lebanon's Shia community — has rejected direct negotiations with Israel [22]. Berri has argued that indirect mediation proved effective in previous cases, including the 2022 maritime border demarcation and the 2024 ceasefire agreement, and that direct talks "require balance and clear negotiating papers" that do not currently exist [22].

The Amal Movement's position has been more nuanced than outright opposition, however. In late February 2026, Berri issued a rare rebuke of Hezbollah and did not block Lebanon's decision to ban Hezbollah's military arm [23]. In December 2025, Berri reportedly sent Tehran three demands including full Lebanese neutrality in any Iran-Israel clash and a religious ruling permitting Hezbollah to surrender precision weapons as part of a U.S.-backed deal; Iran agreed only to continued funding [23].

Foreign Policy described Amal as "trying to walk on the edge of the cliff" — balancing its identity as both a Shia political force and a moderate alternative the West can negotiate with [23].

Broader critics argue that the talks are structurally counterproductive. A Lebanese military source told the Washington Post that Israeli evacuation orders extending 40 kilometers from the border represent an effort "to isolate an entire region of the country and strip it of any effective Lebanese state presence, leaving the state unable to reassert its authority there except on Israeli terms" [2]. From this perspective, U.S.-brokered military coordination with Israel — conducted while Israeli troops occupy Lebanese territory — delegitimizes both the Lebanese state and the LAF domestically, potentially driving recruitment to Hezbollah rather than weakening it.

Realist foreign policy scholars echo this concern from a different angle. The Arab Center Washington DC has argued that "in light of Israeli military excess without any reasonable constraints by the United States, Lebanon is unlikely to preserve its territorial integrity and sovereignty even after taking on the task of disarming Hezbollah" [24].

Proponents counter that the alternative — no direct security channel between the two militaries — leaves enforcement of the ceasefire and future agreements entirely dependent on UNIFIL's limited capabilities and U.S. shuttle diplomacy, neither of which have produced durable results over the past two decades [1].

Historical Precedents: A Mixed Record

The Pentagon talks follow a long tradition of U.S.-brokered security negotiations between regional adversaries, with outcomes that range from transformative to inconsequential.

The Camp David Accords of 1978, brokered by President Jimmy Carter between Israel and Egypt, produced a formal peace treaty in March 1979 that has held for nearly five decades — the most successful example of the format [25]. The treaty ended the state of war between the two countries and fundamentally reoriented Egypt's strategic posture. Within five years, Israel had completed its withdrawal from the Sinai Peninsula.

The Israel-Jordan peace treaty of 1994 similarly produced a durable formal agreement. Security cooperation between the two countries has remained solid for thirty years, though the broader political relationship has been described as a "cold peace" — functional at the military and intelligence level but lacking popular legitimacy in Jordan [26].

The Wye River Memorandum of 1998, brokered between Israel and the Palestinian Authority, illustrates the format's limitations. The agreement outlined phased Israeli withdrawals and mechanisms for combating terrorism, but both parties accused each other of failing to meet their obligations, and implementation was never completed [27].

The Lebanon case differs from all three precedents in a critical respect: neither Israel nor Lebanon is negotiating as a unified sovereign actor. Israel is conducting active military operations in Lebanon while simultaneously negotiating at the Pentagon. Lebanon's delegation represents a state whose government does not exercise a monopoly on force within its own borders. These conditions have no direct parallel in the Camp David, Wadi Araba, or Wye River frameworks.

Tripwires and Timelines

Several factors could collapse the diplomatic track before it produces results.

Ongoing Israeli operations. On the same day the Pentagon talks opened, Israeli troops clashed with Hezbollah along a strategic river in southern Lebanon, pushing farther north [2]. Prime Minister Benjamin Netanyahu has vowed to expand operations. Each military escalation undermines the premise that both sides are negotiating in good faith.

Hezbollah's rearming. While UNIFIL has found no evidence of rearming south of the Litani specifically, the flow of weapons through Syria presents a longer-term challenge to any agreement premised on Hezbollah's disarmament [19][21].

Lebanese political deadlock. The sectarian power-sharing structure that governs Lebanon means that no major security decision can proceed without buy-in from all major communities. With Berri and Amal skeptical of direct negotiations, and Hezbollah outright opposed, the LAF's ability to implement commitments made at the Pentagon depends on political conditions that do not currently exist [22][23].

The ceasefire clock. The 45-day extension expires in late June. U.S. officials have indicated that the June 2-3 political talks and the Pentagon security track are meant to build toward a follow-on agreement, but no specific timeline has been publicly cited [3]. The gap between diplomatic aspiration and ground-level reality — where Israeli forces continue expanding operations and Hezbollah refuses to disarm — remains the central obstacle.

What Comes Next

The Pentagon talks represent a genuine institutional innovation: the first direct military-to-military channel between Israel and Lebanon. Whether that channel produces results depends on variables largely outside the Pentagon's control — Israeli willingness to withdraw, Hezbollah's strategic calculus, Lebanese political cohesion, and the durability of U.S. engagement under an administration whose defense leadership has been described as skeptical of Middle Eastern entanglements [28].

The history of U.S.-brokered regional agreements suggests that the format can work when both parties face sufficient pressure to compromise and when the United States is willing to apply leverage on all sides. At Camp David, Carter pressured both Begin and Sadat [25]. In Lebanon today, the United States has provided $3 billion to the LAF and billions more in military aid to Israel — but has shown limited willingness to condition either relationship on compliance with ceasefire terms [12][24].

The next concrete milestone is the June 2-3 political negotiations at the State Department, where the military discussions from May 29 are expected to inform the diplomatic agenda. The ceasefire extension's late-June expiration provides the most immediate deadline. Beyond that, the trajectory depends on whether both sides — and their U.S. host — treat these talks as the beginning of a genuine security framework or as a diplomatic holding action while the situation on the ground continues to deteriorate.
