The UN seeks a replacement for the UNIFIL mission in Lebanon
UN Secretary-General António Guterres presented the Security Council with three options for the future international presence in Lebanon after the UNIFIL mandate ends. This concerns an area that remains one of the most sensitive security points for Israel: southern Lebanon, the ‘Blue Line’, Hezbollah’s armed infrastructure, and the risk of a new major war on the northern border.
According to Reuters and AP, Guterres’ letter was sent to UN Security Council members in early June 2026. It proposes not just winding down the old mission, but determining what format of international monitoring might remain after December 31, 2026, when the current UNIFIL mandate is set to end.
For Israel, this is not a technical detail.
If the international presence disappears completely, Hezbollah could quickly fill the vacuum in southern Lebanon. However, if the UN maintains at least a limited monitoring format, the international community will retain a tool for pressure, monitoring, and recording violations. The problem is that Israel has long considered UNIFIL a weak mission that failed to prevent Hezbollah’s strengthening along the border.
Three scenarios: from minimal observation to a broader mission
Guterres’ proposals describe three possible models. The first is a light presence with limited capabilities. The second is a more stable format with expanded monitoring and de-escalation support. The third is a large and more complex structure capable of observing the situation more broadly and assisting the political process.
The size of such a presence, according to Reuters and AP, could range from approximately 1,980 to 5,525 people. This is less than the current UNIFIL, which now has about 7,500 military personnel.
The main task of the new format is to maintain military monitoring along the ‘Blue Line’, support the Lebanese Armed Forces, and help achieve the implementation of UN Security Council Resolution 1701, adopted after the 2006 Israel-Hezbollah war. This resolution requires the cessation of hostilities, strengthening the control of the Lebanese army in the south of the country, and the absence of armed groups in the zone where the state should be the only legal force.
On paper, everything looks logical.
In practice, this is where the main conflict of interests begins. Israel demands the real disarmament of Hezbollah and security guarantees for northern communities. Lebanon speaks of sovereignty and the need for the withdrawal of Israeli forces from disputed areas. The UN tries to maintain at least a working mechanism between the parties, but its capabilities depend on Security Council decisions, funding, and the willingness of states to send troops to a dangerous zone.
Why this issue is important for Israel
For Israelis, southern Lebanon is not an abstract map in UN documents. It is the direction from which rockets, attacks, threats, and constant tension have come for decades for the residents of northern Israel. After October 7, the issue of the northern border became even more painful: Israeli society perceives any security promises differently if they are not backed by real control.
That is why Israel is cautious about the new UN plans.
On one hand, international presence can deter escalation, record violations, and help the return of residents to border areas. On the other hand, if the new mission is weak, poorly armed, or politically constrained, it may repeat the fate of UNIFIL: being present but not stopping the actual strengthening of Hezbollah.
UNIFIL’s mandate does not end immediately
The UN Security Council extended UNIFIL’s mandate for the last time in August 2025 — until December 31, 2026. After this date, a phased withdrawal of the mission should begin during 2027. This decision was a compromise after pressure from the US and Israel, which have long criticized the operation’s effectiveness.
This is an important date because it is not about the immediate departure of peacekeepers.
The UN has time to prepare a transitional format. Israel, Lebanon, the US, France, and other participants in the diplomatic process have time to agree on what the new balance in southern Lebanon will be. But time is not abundant, considering the speed at which the situation in the Middle East is changing.
For readers of NANews — Israel News | Nikk.Agency, this story is also important because it shows the overall crisis of international security mechanisms. Israel faces the fact that formal resolutions do not always translate into citizen protection. Ukraine experiences a similar problem in a different geography: international law exists, but the aggressor and terrorist allies often test its strength by force.
What is behind Guterres’ new plan
The UN Secretary-General’s proposals appear against the backdrop of a dangerous period for the entire region. Hezbollah remains a key armed force in Lebanon and part of the Iranian axis of influence. Israel, in turn, is not ready to tolerate a threat on its northern border, especially after the experience of war with Hamas and constant pressure from Iran-backed groups.
The UN is trying to maintain an intermediate line: not to leave southern Lebanon without observation, but also not to continue UNIFIL in its previous form if the Security Council has already decided to end its mandate.
AP separately notes that the new options should help political efforts to implement Resolution 1701, support the Lebanese army, and de-escalate along the ‘Blue Line’. In recent months, the situation has remained dangerous, and the death of peacekeepers has only intensified the question of who and under what conditions is ready to work in this zone.
The main question is not the mission’s name, but its strength
Israel’s interest here is very simple: to ensure that southern Lebanon does not become a convenient platform for a new war. The name of the future mission is secondary. Much more important is whether it will have a real mandate, access to violation sites, Security Council support, and the ability not only to observe but also to achieve consequences for those who turn border areas into military infrastructure.
For Lebanon, the issue is also painful. The state must prove that its army is capable of being the only legitimate force throughout the country’s territory. Without this, any international format will be a temporary support, not a solution.
In the coming months, the UN Security Council will have to choose which of the three options will form the basis for further negotiations. For Israel, this will not be a diplomatic formality, but one of the security factors for the northern border.
That is why the new discussion around UNIFIL is important not only for New York, Beirut, or the UN headquarters. It directly concerns Kiryat Shmona, Metula, Nahariya, Haifa, and all Israelis who understand: if the north ignites again, the cost of weak international decisions will be measured not in resolutions, but in human lives.
