The interim understanding between the US and Iran has moved the Middle East away from immediate war, but its first serious test has arrived almost as quickly as the ink on the text reached Washington. The White House has sent the agreement to Congress, a 60-day negotiating clock has begun, and the Strait of Hormuz, sanctions relief, frozen funds, nuclear assurances and regional security are now part of a compressed diplomatic timetable. Yet the future of this entire arrangement may be decided first in Lebanon, where Israel and Hezbollah are said to have agreed to a ceasefire that remains burdened by mistrust, competing interpretations and the continued presence of Israeli forces in parts of the south.
This is the fragility at the heart of the moment. A ceasefire brokered through American and Qatari channels with Iranian assistance can lower the temperature, but it cannot by itself resolve the question that brought the talks under strain: whether Lebanon will be treated as a side theatre or as a core condition of any wider US-Iran settlement. Tehran has made clear that Israeli military activity in Lebanon undermines the spirit of the interim arrangement. Israel, for its part, continues to frame its actions through the language of security and deterrence and between these positions lies the space in which diplomacy can still fail.
The equation is particularly difficult for Israeli Prime Minister Benjamin Netanyahu, whose entire political career has long rested on the claim that he understands Washington, can contain Iran and can guarantee Israel’s security through a zero-sum game. The new diplomatic track challenges each of those claims. If he accepts the process, he risks angering a hard-right coalition that wants military pressure on Iran and Hezbollah sustained. Similarly, if he seeks to preserve freedom of action in Lebanon, he risks appearing to undermine a deal that President Trump now wants to present as a regional breakthrough.
This is why the next stage will require more than signatures and statements. The language of reconstruction funds, sanctions sequencing and maritime access will matter, but so will the more immediate questions of who stops firing, who withdraws, who verifies compliance and who pays the political cost of restraint.
As rightfully acknowledged by Prime Minister Shehbaz Sharif in the National Assembly, Pakistan’s role in the last three-and-a-half months has placed Islamabad in a position of unusual diplomatic visibility. “Many nations spend centuries seeking such honour, but fail to achieve it. Today, Pakistan’s name is being mentioned around the world with respect and dignity,” he said, while crediting the country’s civil and military leadership for keeping the process alive when the ceasefire effort seemed close to collapse. This rare diplomatic opening, however, also brings great responsibility. Mediation cannot end with the announcement of a memorandum, and henceforth, its value will be judged by how it helps sustain the difficult, technical work that follows. *
