The announcement of an interim peace agreement between Washington and Tehran, brokered with Pakistani mediation and set for formal signing in Geneva on 19 June, has collided immediately with fierce Israeli opposition. Prime Minister Benjamin Netanyahu, in a telephone conversation with President Donald Trump, made clear that Israel does not consider itself bound by any clause restricting its military operations against Hezbollah in Lebanon. Israeli media reported that Netanyahu received unanimous backing from his cabinet for this stance, and that he is seeking an urgent meeting with Trump to clarify Israel's red lines. The deal, which Tehran and Islamabad say mandates an immediate and final cessation of hostilities on all fronts, including Lebanon, has thus been met with a blunt rejection from Jerusalem before the ink is even dry.

Defence Minister Israel Katz articulated the government's policy in unvarnished terms: the Israel Defence Forces will remain indefinitely in what he termed "security zones" in Lebanon, Syria, and Gaza. Katz described the seizure of these territories as one of the military's greatest achievements and said the areas would be "cleared of local residents" and all infrastructure, including homes in border villages, destroyed. National Security Minister Itamar Ben Gvir went further, declaring on social media that "Trump's agreement does not bind us" and that Israel is "not a banana republic" subordinated to the United States. Energy Minister Eli Cohen added that Israel is prepared to confront Iran alone if necessary. The common thread across these statements is an insistence that nothing short of the full dismantling of Hezbollah is acceptable, and that no territory captured by Israeli soldiers will be surrendered.

Viewed from Washington, the interim deal represents a diplomatic breakthrough aimed at winding down a conflict that began with US-Israeli strikes on Iran in February and drew in Hezbollah after the assassination of Iran's supreme leader. From Tehran's perspective, the inclusion of Lebanon is a non-negotiable element, linking the nuclear file to a broader regional de-escalation. Yet in Jerusalem, the agreement is seen as a strategic threat that would freeze Israel's military gains and leave Hezbollah's infrastructure intact. The dissonance was underscored by a massive Israeli assault on Lebanon on Sunday, hours before the deal's announcement, which critics described as a violation of the spirit of the emerging truce.

The Israeli reaction reflects deep domestic political pressures. Netanyahu's coalition depends on far-right partners like Ben Gvir and Finance Minister Bezalel Smotrich, who have threatened to collapse the government if operations against Hezbollah are curtailed. Former prime minister Naftali Bennett, a leading opposition contender, seized on the moment to accuse Netanyahu of failing to convert tactical victories into lasting security, arguing that the country has been drawn into endless wars of attrition. Analysts in European capitals note that Israel's defiance places Trump in a difficult position, balancing a signature foreign-policy achievement against the risk of a close ally acting as a spoiler.

With the Geneva signing days away, the central question is whether the Lebanon clause can survive Israel's outright rejection. Katz has warned that if Iran attacks Israel over developments in Lebanon, Israel will retaliate with "great force." The Israeli military has extended the state of emergency on the home front until 30 June, citing uncertainty over both Lebanon and Iran. The interim deal may yet hold if Washington can persuade Jerusalem to accept a separate, parallel understanding on Lebanon, but the current rhetoric suggests Israel is prepared to continue its campaign unilaterally, potentially unravelling the broader peace framework before it takes shape.
