Lebanon After the Islamabad Understanding: Qatar’s Role and the Limits of the Transition from War Management to Settlement Management

The U.S.–Iranian understanding announced under Pakistani sponsorship has reopened the door to a new political phase in the Middle East. However, the Lebanese arena quickly emerged as the first practical test of this understanding’s ability to endure and translate into realities on the ground. While the agreement was expected to reduce tensions across the various fronts linked to the U.S.–Iran confrontation, Israeli military operations in southern Lebanon continued, revealing a gap between the political understanding on the one hand and the field reality on the other.

In this context, Qatar emerged as the regional actor most deeply involved in managing the transitional phase that followed the agreement. Its role is no longer limited to traditional mediation or the transmission of messages between parties. Rather, it has expanded to encompass efforts to connect three parallel tracks: the implementation of the U.S.–Iranian understanding, the Lebanese–Israeli negotiations, and the broader regional effort aimed at building a political, security, and economic framework capable of preventing the return of escalation to the Lebanese arena.

The main question facing the concerned parties today is not merely whether a ceasefire can be sustained, but whether this ceasefire can be transformed into an entry point for a broader settlement that includes an Israeli withdrawal, border security arrangements, the role of the Lebanese state, and the future of southern Lebanon in the years ahead.

First: How Did the Islamabad Understanding Change Lebanon’s Position in the Regional Equation?

For the first time in years, Lebanon is no longer being discussed in influential capitals as an isolated file or a border crisis detached from wider regional balances. The recent war, along with the direct confrontation between the United States and Iran that accompanied it, has integrated the Lebanese arena into the emerging regional negotiation framework.

In previous phases, the Lebanese file was largely managed through separate channels linked either to the Lebanese–Israeli conflict or to Lebanon’s internal political balances. Following the U.S.–Iranian understanding, however, Lebanon has become part of a broader negotiating framework encompassing regional security, the future of Iranian influence, and mechanisms for de-escalation across the Levant.

This transformation did not result from a declared political decision but rather from realities imposed by the war itself. The Lebanese front was one of the arenas most closely connected to the broader regional conflict, and any return to escalation there would be sufficient to reopen channels of confrontation between Washington and Tehran, either directly or indirectly. Consequently, Lebanon’s stability has become a shared interest among the parties involved in the understanding, even if their motivations and ultimate objectives differ.

Second: From Mediation to Managing Intersections – The Rise of Qatar’s Role

The significance of Qatar’s current role lies in the fact that it goes far beyond the traditional functions that Doha has assumed during previous crises. In earlier experiences, Qatar generally acted as a mediator between rival parties or as a sponsor of specific agreements. In the current phase, however, it is acting as an actor managing the intersection of multiple regional and international tracks simultaneously.

Qatar maintains effective working channels with the United States, Iran, Lebanon, and several key regional powers, foremost among them Türkiye and Saudi Arabia. It was also part of the political effort accompanying the U.S.–Iranian negotiations while simultaneously remaining engaged in the Lebanese file through multiple political, security, and economic channels.

As a result, Qatar’s role has become closely linked to preventing contradictions between the different tracks. Doha is working to prevent the Lebanese arena from becoming a factor that threatens the U.S.–Iranian understanding, while also seeking to prevent Lebanese–Israeli negotiations from evolving into a separate track capable of undermining broader regional understandings. Accordingly, Qatar is attempting to preserve the coherence of the negotiating landscape as a whole rather than merely managing one part of it.

Third: The Israeli Dilemma and the Attempt to Modify the Terms of Settlement

Despite Washington’s welcome of the understanding with Iran, there are no indications that Israel views the new phase through the same lens.

Available indicators suggest that the Israeli government believes that any long-term stabilization in southern Lebanon will inevitably lead to international pressure concerning withdrawal arrangements, border security mechanisms, and the future of Israel’s military presence in areas entered by its forces during the war.

From this perspective, much of the Israeli escalation that followed the announcement of the U.S.–Iranian understanding can be understood. The issue is not solely related to military considerations on the ground but also to an effort to improve Israel’s negotiating position before entering the political phase.

Tel Aviv understands that any final settlement will address sensitive issues, including withdrawal, the deployment of the Lebanese Armed Forces, and international monitoring mechanisms. It therefore seeks to enter these negotiations while holding the maximum possible number of military and operational leverage points.

Fourth: What Is Actually Being Negotiated?

Contrary to common perceptions, the current negotiations are not focused solely on a ceasefire.

The cessation of military operations is, in reality, merely the introduction to a more complex negotiating process concerning the future of southern Lebanon. Available information suggests that the ongoing discussions encompass an interconnected set of issues:

• Israeli withdrawal and its geographical and temporal mechanisms.
• The deployment of the Lebanese Armed Forces in areas vacated by Israeli forces.
• The role to be played by international monitoring forces and security oversight mechanisms.
• The future of weapons outside state institutions and how to address them within gradual long-term arrangements.
• Reconstruction and the economic and financial support necessary to ensure the stability of the new phase.

Accordingly, what is being negotiated today is, in essence, the shape of the political and security order that will govern southern Lebanon after the war, rather than a mere temporary ceasefire.

Fifth: Potential Scenarios in the Coming Months

1. The Gradual Stabilization Scenario

This scenario assumes that mediators succeed in consolidating the ceasefire, followed by phased Israeli withdrawals accompanied by broader deployment of the Lebanese Armed Forces and a strengthened role for international monitoring mechanisms. This remains the scenario most aligned with the interests of the United States, Qatar, and most regional actors.

2. The Israeli Obstruction Scenario

This scenario assumes that Israel continues attempting to impose additional conditions related to the border zone or freedom of military movement, resulting in slower negotiations and transforming the process into a prolonged and open-ended one.

3. The Collapse and Re-Escalation Scenario

Although this remains the least likely scenario at present, it cannot be ruled out if the parties fail to reach understandings regarding withdrawal and security arrangements, or if Israel or another actor decides to reuse the Lebanese arena as leverage in broader regional disputes.

Conclusion and Assessment

Current indicators suggest that Lebanon has entered a new phase distinct from those that followed previous wars. The issue is no longer confined to ending military operations or managing the consequences of war; rather, it has become part of a broader process of reshaping regional balances following the U.S.–Iranian understanding.

At the center of this process stands Qatar, serving as one of the most important mechanisms linking the various tracks. Yet the success of this role will remain dependent on its ability to transform the ceasefire from a temporary measure into a gateway for more sustainable understandings regarding withdrawal, security arrangements, and reconstruction.

Accordingly, the real challenge in the coming phase will not simply be maintaining calm, but building a political and security framework capable of preventing southern Lebanon from returning to its previous status as an open arena of confrontation within wider regional conflicts.
