Israeli warplanes struck targets across eastern Lebanon's Bekaa Valley on Monday, marking the first bombardment of the region since a United States-brokered ceasefire took hold on 16 April and signalling a dangerous expansion of military operations that threatens to unravel the fragile truce entirely. The raids, which the Israel Defence Forces said targeted Hezbollah infrastructure, came hours after a drone attack inside Lebanon killed one Israeli soldier and wounded six others — the deadliest single incident since the cessation of hostilities was declared. Viewed from Jerusalem, the logic was unambiguous: Prime Minister Benjamin Netanyahu declared that Hezbollah's rockets and drones remained an intolerable threat demanding forceful action, while Defence Minister Israel Katz warned that the group's rejection of diplomatic overtures would bring catastrophic consequences for Lebanon.

The strikes landed as a bitter and increasingly public rift tore through Lebanon's political establishment. President Joseph Aoun, whose government has taken the historic step of holding direct ambassadorial-level talks with Israel in Washington, accused those who dragged the country into war of committing treason — an unmistakable barb aimed at Hezbollah. The Iran-backed movement's secretary-general, Naim Qassem, had earlier denounced the negotiations as a sin and insisted his forces would neither recognise their outcomes nor lay down their arms. For a Lebanese state long paralysed by the militia's veto power, Aoun's willingness to confront Hezbollah so openly reflects a calculation that the group's regional position has weakened sufficiently to permit a reassertion of sovereign authority. Analysts in London note, however, that the president commands no military force capable of imposing his will, and Hezbollah's rejection of any settlement that leaves it disarmed sets the stage for a constitutional crisis as much as a security one.

The ceasefire itself was always an imperfect instrument. Brokered during two rounds of talks between Lebanese and Israeli diplomats in the American capital and announced by President Donald Trump as a ten-day pause before being extended by a further three weeks, it never fully halted the exchange of fire. Israeli troops remain in occupation of a strip of southern Lebanon, demolishing structures the military describes as Hezbollah infrastructure, while the group has continued to claim attacks on Israeli positions. Miri Regev, a member of Israel's security cabinet, conceded the arrangement amounted to little more than a porous ceasefire. From the northern Israeli town of Kiryat Shmona, Mayor Avichai Stern voiced the frustration of frontline communities, accusing the government of treating residents as sitting ducks and demanding that decision-makers relocate their families north to witness the reality.

Regionally, the widening theatre of strikes carries ominous echoes. The Bekaa Valley, a Hezbollah stronghold deep inside Lebanese territory, had been spared since the truce began; its inclusion now suggests that Israel's military calculus no longer distinguishes meaningfully between southern border zones and the group's heartland. Viewed from Washington, the diplomatic track appears increasingly disconnected from battlefield dynamics, with the Trump administration's signature truce at risk of becoming a footnote in a longer cycle of escalation. Tehran, for its part, has watched its most capable proxy come under simultaneous military and political pressure without, as yet, committing to direct intervention. Whether the Lebanese state can convert this moment into a durable assertion of sovereignty — or whether the country slides back into a war that neither Hezbollah's patrons nor Israel's Western allies appear able to arrest — now depends on a diplomatic window that is closing with every airstrike.
