Israel and Hezbollah agree to renewed ceasefire, saving fragile US-Iran peace deal

Israel and Hezbollah have agreed to a renewed ceasefire in Lebanon, halting a deadly 24-hour military flare-up that threatened to unravel the newly signed peace agreement between the United States and Iran.[1][4]

The truce, brokered urgently by U.S. and Qatari mediators, took effect at 4 p.m. local time on Friday. It follows a fierce exchange of fire that saw Israel strike more than 80 Hezbollah targets, while the Iranian-backed militant group launched retaliatory attacks.[3][5][6]

The overnight violence exacted a heavy toll, killing at least 47 people in Lebanon and four Israeli soldiers, including a battalion commander whose tank was struck in the village of Kfar Tebnit.[1][6]

More broadly, the sudden escalation in the Levant posed the first existential test for the U.S.-Iran memorandum of understanding, signed earlier this week to end a devastating three-and-a-half-month war.[2][3]

The immediate diplomatic casualty of the Lebanon clashes was a planned meeting in Switzerland. U.S. and Iranian officials were forced to postpone Friday's technical negotiations, and Vice President JD Vance delayed a trip to lead the American delegation.[1][3][4]

However, rapid intervention by regional mediators managed to pull the warring parties back from the brink. By Friday afternoon, a Gulf diplomat confirmed that hostilities had ceased, allowing the broader Washington-Tehran peace framework to survive its fragile first week.[3][5]

The global stakes for the U.S.-Iran deal are massive. The conflict, which erupted on February 28 following U.S.-Israeli strikes, effectively closed the Strait of Hormuz, choking off a critical artery for global energy supplies and rattling international markets.[2][7]

In an interview with Axios, President Donald Trump defended the agreement as an "unconditional surrender" by Tehran. He argued that finalizing the deal was an absolute necessity to prevent the maritime blockade from triggering a worldwide economic depression.[2][7]

The economic relief is already materializing. On Thursday, U.S. Central Command officially lifted all blockade enforcement on maritime traffic entering and exiting Iranian coastal areas.[2][7]

Within hours, the Strait of Hormuz saw its highest traffic since mid-April, with at least 25 commercial vessels and oil tankers successfully transiting the newly reopened waterway.[3]

Despite the resumption of global trade, the peace deal has exposed a severe and highly public rift between the Trump administration and the Israeli government.[1][4]

Israeli Prime Minister Benjamin Netanyahu's cabinet has expressed deep reservations about the U.S.-Iran pact, arguing that it leaves Tehran's nuclear infrastructure intact and fails to neutralize its regional proxy network.[1][4]

Prior to Friday's ceasefire, Netanyahu vowed to exact a "very heavy price" from Hezbollah and insisted that the Israel Defense Forces would maintain a security buffer zone in southern Lebanon "for as long as required."[1][3]

The White House has pushed back forcefully against Israeli criticism. Vice President Vance issued a stark public warning to hardline Israeli ministers, including Itamar Ben-Gvir and Bezalel Smotrich, urging them to stop attacking the U.S.-Iran agreement.[4][6]

"If I was in the cabinet of the Israeli government, I might not be attacking the only powerful ally that I have anywhere left in the entire world," Vance told reporters, bluntly reminding Israel that two-thirds of its defense weapons are funded and built by Americans.[4]

On the Iranian side, the political dynamics are equally complex. Newly installed Supreme Leader Ayatollah Mojtaba Khamenei, who succeeded his father following the February strikes, approved the accord while publicly noting he held a "different view."[3]

Tehran's foreign ministry spokesperson Esmaeil Baghaei explicitly blamed the United States for the Israeli strikes in Lebanon, citing the first clause of the U.S.-Iran memorandum which calls for the immediate termination of military operations on all fronts.[4]

Iranian negotiators have warned that their finger remains "on the trigger" if Israel continues its military campaigns, even as they prepare to negotiate the release of billions in frozen assets.[3]

With the Lebanon front temporarily quieted, U.S. and Iranian diplomats are now working to reschedule their Swiss talks. The upcoming negotiations will focus on the mechanics of sanctions relief, nuclear downblending, and long-term regional security.[1][3]

The coming weeks will determine whether this battlefield pause can translate into a permanent geopolitical settlement, or if the deeply entrenched proxy conflicts in the Middle East will inevitably drag Washington and Tehran back into direct confrontation.[2][5]
