Three Years Later, Lebanon Is Where Peace Could Emerge

Three years ago this fall, Hamas’ massacre in southern Israel exposed how far Israeli deterrence had eroded. Only months before the attack, Hezbollah pitched military tents on the Israeli side of the border near Mount Dov. Israel’s own national security adviser called the move “childish,” yet for weeks the tents stood. Removing them risked a wider war Israel wasn’t ready to fight, so Jerusalem absorbed the provocation instead. That restraint, understandable at the time, was itself a symptom of the problem: Iran and its proxies had learned that Israel could be provoked and would not always respond.

Compare that to what happened in Lebanon this month. Israeli forces located, besieged and destroyed Hezbollah’s main underground command complex beneath the Ali al-Taher ridge in the south, a fortress the organization had spent years building. Iran, which fought a direct war against Israel just months earlier and still possesses the arsenal to make good on threats, warned Washington over the strike and then did nothing. No missiles. No proxy escalation. A regime that went to war with Israel this year chose to swallow the loss of one of Hezbollah’s most important assets rather than reopen a front it has already tested.

That is not a small data point. It is the clearest evidence yet that the balance of fear in the north has flipped. Hezbollah’s own leadership has acknowledged that the group temporarily lost its arms-resupply route through Syria after Assad’s fall, and independent analysts across the region now describe Iran’s axis in Lebanon as badly shaken, its command structure gutted, its weapons pipeline in doubt. No serious observer should call the axis finished; Iran has surprised the region with its patience before. But “badly shaken” is itself a strategic opening Israel and the United States have not had in decades, and it will not stay open indefinitely.

The good news is that Israel and Lebanon are not waiting to find out. For the first time in decades, the two countries are engaged in direct diplomatic talks, brokered by Washington, with multiple rounds of trilateral meetings this year producing joint statements on next steps. This is a different kind of process than the periodic, unofficial arrangements that have governed the border since 2000: the 2006 ceasefire that ended in violation, the maritime deal that resolved one dispute while leaving the land border a live wound. A direct table, with both governments’ names on the communique, is the first realistic chance in a generation to turn a ceasefire line into an actual, negotiated border.

It would be a mistake to let this moment pass the way Israel and the United States let earlier ones pass. After the 2006 war, international attention lasted only months before Hezbollah quietly rearmed under UNIFIL’s nose. After the maritime deal in 2022, momentum for a land settlement never materialized. Lebanon’s own state is now weaker and more dependent on outside support than it has been in years, precisely because Hezbollah’s grip on its south has been broken by force rather than by Lebanese institutions. That is uncomfortable, but it is also an opportunity: a Lebanese government that wants to reclaim sovereignty over its own territory needs an American security guarantee and reconstruction investment that make disarmament and border demarcation survivable at home. Washington has both to offer, and Beirut has shown, by coming to the table at all, that it is willing to take the deal.

For Israel, dismantling Hezbollah’s military infrastructure was tactically necessary. It cannot be the strategic finish line. A Lebanon at the table today could easily be a Lebanon back at the mercy of a rebuilt Hezbollah in five years if the diplomatic track stalls while attention moves elsewhere; that is exactly the sequence the 2006 war left in its wake, and there is no reason it could not repeat. The difference this time is that Israel finally holds the leverage that comes from having disrupted the axis at its source, and Lebanon finally has a government willing to negotiate directly rather than through Hezbollah as an intermediary.

Three years after October 7 exposed how badly deterrence had failed, the north offers the first real evidence that it has been rebuilt. Turning a battlefield advantage into a signed, enforceable agreement with a sovereign Lebanese state, before the current alignment of interests fades, is the single most consequential thing American diplomacy can do in the region right now. It took a war neither side wanted to get here. It would be a strategic failure of historic proportions to let the opportunity slip away for lack of sustained attention.
