The next round of Lebanon-Israel talks in Tampa, Florida, is shaping up as more than a technical military meeting, with a proposed system of “experimental zones” emerging as one of the most sensitive issues on the agenda.

The meeting, tentatively scheduled for Oct. 20-22 at the headquarters of the U.S. Central Command, is expected to focus primarily on military and technical matters. But the issues under discussion go directly to Lebanese sovereignty, Israel’s military presence in southern Lebanon, the role of the Lebanese army and the future of Hezbollah’s weapons.

At the heart of the talks is a gradual mechanism under which a limited area would serve as a test case for a broader security arrangement.

Under the concept being discussed, Israel would withdraw from a designated area, the Lebanese army would deploy there and a verification mechanism would then assess whether state authority had been fully restored and whether unauthorized weapons or armed activity remained.

If the first test were deemed successful, the same model could be extended to other areas, turning a broad political formula into a series of concrete territorial steps.

The approach could provide a pathway toward a gradual Israeli withdrawal. But its outcome will depend heavily on how the first zone is defined and what obligations are imposed on each side.

If the first experiment clearly involves transferring territory from Israeli military control to the exclusive authority of the Lebanese army, it could become the starting point for a wider withdrawal. If, instead, Lebanon is required to fulfill a series of security obligations in areas where Israel is not physically deployed while its withdrawal from occupied territory is postponed, the mechanism would take on a very different character.

It could effectively become a system of security conditions imposed inside Lebanese territory.

Who Will Lead the Lebanese Delegation?

The Lebanese delegation could be headed by Simon Karam, with Ambassador Nada Hamada Moawad also participating.

The composition itself reflects a disagreement over the nature of the talks. Beirut has sought to broaden the discussions and give them a diplomatic dimension, while Israel has so far favored keeping the meeting within a military framework.

If Israel sends a strictly military delegation and the talks produce no political progress, Beirut may question the value of involving senior diplomats in the process.

What Are the “Experimental Zones”?

The term may sound abstract, but the concept is essentially a controlled test of how a future security arrangement would work on the ground.

The mechanism would involve four basic stages: an Israeli withdrawal, deployment of the Lebanese army in the evacuated area, verification that no armed presence outside state control remains, and confirmation that military and security authority has effectively passed to the Lebanese state.

Once that sequence is completed, another area could be selected.

The intention, in principle, is not to establish a series of disconnected enclaves, but to test a model that can be progressively expanded. That makes the first zone particularly important: if the mechanism works, it could become the template for subsequent stages.

The more difficult question is what exactly the verification process would entail.

Would it be enough to confirm that the Lebanese army controls roads and military positions? Would suspected Hezbollah facilities have to be inspected? Could homes be searched? Who would determine whether an area complies with the agreement? Could Israel request inspections based on intelligence it provides? And who would settle a dispute if Israel says a violation exists and Lebanon denies it?

Preparatory documents reportedly include the search of homes among the issues that could be discussed in Tampa, underscoring that the talks could address the exercise of state authority inside Lebanese villages, rather than simply the demarcation of military lines.

Tallet Ali Al-Taher Complicates the Equation

The area around Tallet Ali Al-Taher illustrates the challenge.

The area has been discussed as a possible candidate for an experimental zone, but military conditions have evolved. Israel is now described as reluctant to relinquish the hill and surrounding territory, in part because the position could serve as a strategic foothold for a deployment toward the Rihane area.

That could alter the original concept.

A territory initially considered suitable for testing an Israeli withdrawal could instead become an area Israel seeks to retain for operational reasons. One possibility would then be to expand the first experimental zone to include additional sectors rather than establish a second zone around Tallet Ali Al-Taher.

The geography of southern Lebanon is central to the negotiations. A hill, road or village is not simply a piece of territory. Elevation, visibility, access and proximity to other military positions determine its strategic importance.

Giving up high ground is therefore not equivalent to leaving an area with little strategic depth. Similarly, transferring control of a village to the Lebanese army would not necessarily resolve the security issue if surrounding heights remained under Israeli control.

The choice of each zone could therefore predetermine part of the eventual outcome.

For Lebanon, that makes the zones more than technical military details. They will determine the sequence in which sovereignty can be restored and the areas in which that process could be delayed.

Nabatieh Al-Fawqa and Iqlim Al-Tuffah

Another potentially significant shift concerns the types of territory that could be included.

The zones may not be limited to areas currently occupied by Israel. Areas that are not physically occupied but remain exposed to Israeli firepower could also be considered. Nabatieh Al-Fawqa and positions in Iqlim Al-Tuffah have been cited in this context.

That distinction is crucial.

In an occupied area, the logical first step is an Israeli withdrawal followed by a Lebanese army deployment. In an area where Israeli troops are not physically present, however, the process could begin with obligations imposed directly on the Lebanese army.

Those could include entering Hezbollah positions, inspecting infrastructure and preventing armed personnel from remaining in or returning to certain areas.

That would reverse the sequence originally envisaged.

An Israeli withdrawal would no longer necessarily be the first move. Lebanese action against Hezbollah's military infrastructure could instead become a condition for securing an Israeli withdrawal later.

That is particularly sensitive for Beirut. Lebanon has repeatedly affirmed its objective of establishing a state monopoly on weapons, but it does not want that process to become an arrangement under which Israel dictates, locality by locality, what operations the Lebanese army must carry out.

State sovereignty also means that Lebanon determines how its own armed forces are organized and deployed.

The Lebanese army has therefore rejected outside interference in the composition of its units or its operational methods. Coordination aimed at preventing accidental clashes is one thing; coordination that allows Israel to influence the missions of the Lebanese army is another.

The Central Question: Who Will Verify?

Even if the two sides agree on the geographic boundaries of an experimental zone, the question of verification could remain the biggest obstacle.

Lebanon does not want verification to be conducted exclusively by Israel, arguing that this would give one party to the dispute the unilateral power to determine whether the other is complying.

A simple scenario illustrates the problem.

If Israel says it has intelligence indicating that a house contains weapons and the Lebanese army searches the property but finds nothing, who decides whether the inspection was sufficient? Can Israel demand another search? Can it insist on a further operation? Should an international representative be present? And what authority would such an observer have to enter private property in Lebanon?

An international third party could help resolve some of those disputes by observing operations and providing an independent record of what happened. It could also reduce the risk that a technical disagreement immediately becomes grounds for another Israeli strike.

But establishing such a mechanism presents its own challenges.

Italy has been mentioned as one possible participant. It is reportedly proceeding cautiously, however, with an Italian intelligence official who recently returned from Lebanon said to have found that adequate guarantees had not yet been secured for the safety of personnel or the conditions needed to carry out the proposed missions.

Any international observers deployed to an area where strikes remain possible would require clear rules of engagement, security guarantees and a precise definition of their authority.

The political space is also narrow.

Israel is wary of an international presence that could constrain its freedom of military action in southern Lebanon. Hezbollah, meanwhile, rejects an international presence operating outside the U.N. framework and a mandate clearly linked to Security Council Resolution 1701.

That leaves little room for designing a mechanism acceptable to all sides.

UNIFIL Remains at the Center

The verification question is inseparable from the future of the United Nations Interim Force in Lebanon, or UNIFIL.

For decades, the U.N. force has provided the international framework in southern Lebanon. Even when its role has been criticized as insufficient, it has had an established mandate, chain of command, identifiable contingents and legitimacy from the Security Council.

Its departure could create a vacuum at precisely the moment when a future withdrawal mechanism needs an accepted third party to monitor events on the ground.

That explains efforts to preserve UNIFIL or develop an international mechanism to replace it.

Four broad options are being considered: maintaining UNIFIL in something close to its current form; establishing a new international force under a U.N. mandate; creating a European or multinational mission to assist the Lebanese army; or relying primarily on strengthening the Lebanese army without deploying a comparable international force.

Those models are not equivalent.

An assistance mission could train, equip and finance the Lebanese army without having authority to determine whether a violation has occurred. An international force could monitor compliance without necessarily having inspection powers. A European mechanism could be acceptable to some parties but rejected by others if it operates outside U.N. authority.

The future of UNIFIL is therefore directly connected to the Tampa talks.

If an area is transferred from Israeli control to Lebanese control, someone will have to establish that the withdrawal has taken place, that Lebanese troops have deployed and that the agreed commitments have been fulfilled.

Without a third party accepted by both sides, every incident could produce competing accounts that neither side recognizes.

Israel's Election Adds Another Constraint

The timing of the meeting is another complication.

Israel's Knesset election is scheduled for Oct. 27, only days after the period being considered for the Tampa talks. Prime Minister Benjamin Netanyahu will therefore be entering the final days of his campaign at the same time his government could potentially be asked to withdraw from some military positions.

That makes a major Israeli concession politically difficult.

Netanyahu's opponents could portray a withdrawal as a retreat, while the prime minister is seeking to project strength and control over security issues. Electoral considerations do not necessarily dictate military decisions, but they can narrow the space for compromise before the vote.

Washington appears to be factoring that timeline into its approach.

The U.S. objective may not be to secure a comprehensive agreement before Oct. 27, but rather to keep the negotiating channel open through the election and the subsequent formation of a government.

A military meeting that produces limited progress could nevertheless keep the process alive.

That also helps explain Israeli resistance to giving the Tampa meeting a broader diplomatic character. Discussions centered on maps, troop movements and technical procedures are politically less costly than an openly declared negotiation over Israeli withdrawal and Lebanese sovereignty.

For Lebanon, however, waiting also carries risks.

A pause until after the Israeli election may be logical if no significant concession is possible before the vote. But each additional week could give Israel more time to strengthen its positions on the ground.

Diplomatic and military timelines are therefore moving in opposite directions.

Hezbollah's Weapons at the Center of the Dispute

The Tampa talks are also expected to confront Beirut with demands directly related to Hezbollah's weapons.

The discussions could include specific timelines and operational commitments for removing weapons, meaning that the issue would move beyond the general principle of a state monopoly on arms and toward the practical steps needed to enforce it.

Israeli officials have also claimed that Hezbollah is redeploying some of its capabilities farther north, including toward Iqlim Al-Tuffah, Jabal Al-Rihane and Jabal Safi.

Those claims come from the Israeli side and do not by themselves constitute independent confirmation. But they serve a clear purpose in the negotiations: reinforcing Israel's argument that a limited withdrawal from the border area would not be sufficient to remove what it considers a security threat.

For Lebanon, the concern is that the scope of the process could gradually expand.

If every alleged Hezbollah redeployment leads to a new verification area farther north, a mechanism originally designed to organize an Israeli withdrawal could become a means of imposing security conditions over an expanding part of Lebanese territory.

That is why the geographic boundaries of each zone need to be tied to a clear timetable.

A test zone can only work if its consequences are defined in advance. If the first area is declared compliant, the next should follow under an agreed procedure. Otherwise, each stage could become an opportunity to reopen the entire negotiation.

The Most Sensitive Issue: Searching Homes

Among the technical issues, searches of private homes could prove the most explosive.

The issue involves not only security but also property rights, residents' trust and the legitimacy of the Lebanese army.

In southern villages, asking the army to inspect homes based on intelligence supplied by another country is not a neutral act. The parties would have to establish what level of evidence is required, who can authorize a search and what legal procedures apply.

Without clear rules, the mechanism could create tensions between the army and the communities it is meant to protect.

There is also a serious operational risk.

If Israel claims that a home contains weapons and the Lebanese army finds no evidence of them, Israel could later argue that the mechanism had failed and use that as a justification for another strike.

But if every piece of Israeli intelligence automatically triggers a Lebanese army search, Israel would effectively acquire an indirect means of directing security operations inside Lebanon.

An international observer would not necessarily resolve that contradiction. It could provide an additional witness, but the fundamental question would remain: who has the final authority on Lebanese territory?

The Test Must Lead to the Next Step

The greatest risk is that the experimental zones cease to be temporary tests and instead become permanent arrangements.

One area could be evacuated and stabilized without the next following. The result could be a patchwork of territories with different statuses: some under Lebanese army control, others still occupied by Israel and others subject to continuing international or security monitoring.

Avoiding that outcome would require at least three elements in any roadmap: a clearly defined territorial sequence, deadlines and a mechanism for resolving disputes.

The parties would need to know which area comes next, how long each stage lasts and what happens when one side claims the other has failed to meet its commitments.

Without those guarantees, Lebanon could fulfill its obligations in one area without automatically securing an Israeli withdrawal from the next. New conditions could emerge at every stage, turning the process into an open-ended negotiation.

But rejecting a gradual approach altogether also carries risks.

Without a withdrawal mechanism, Israeli positions could become increasingly entrenched. Military installations could be reinforced, access roads improved and a presence initially described as temporary could gradually become a long-term deployment.

That leaves the Tampa talks facing two competing dangers.

One is accepting a mechanism that could indefinitely condition Israel's withdrawal on Lebanese security measures. The other is allowing the absence of an agreement to turn a temporary occupation into a lasting reality.

The key question, therefore, is not simply whether Lebanon and Israel agree to the concept of “experimental zones.” It is what those two words actually mean on the ground: where the first zone begins, who controls it after an Israeli withdrawal, who verifies compliance, what powers the verifier has, how long the process lasts and which area follows next.
