Why the U.S.-Iran Ceasefire Is Poised to Collapse

On Saturday, a U.S. delegation headed by Vice President JD Vance will meet Iranian officials in Islamabad, a move brokered by Pakistan to salvage the fragile U.S.-Iran ceasefire. The pause, announced after days of escalating rhetoric, is already showing cracks.

U.S.-Iran ceasefire under siege

Israel’s renewed bombardment of Lebanon – ↓ 300 dead and ↓ 1,150 wounded on Wednesday alone – highlights the absence of any enforceable framework. Netanyahu’s insistence on continuing strikes, coupled with ambiguous language about whether Lebanon falls within the cease‑fire’s scope, turns the truce into a tactical lull rather than a durable settlement.

“A war paused without a political bargain is a conflict deferred,” a senior analyst told Reuters.

For Israel, the confrontation with Tehran is now entwined with Prime Minister Benjamin Netanyahu’s domestic calculus; his political survival hinges on projecting strength against a perceived Iranian menace. Even limited setbacks have not altered his calculus that a fully neutralised Iran would be the only acceptable outcome.

Iran, meanwhile, has survived the onslaught. Its missile arsenal, decentralized command, and proxy network remain functional, and sanctions relief discussions in Washington could soon restore economic breathing space. Should Tehran leverage the Strait of Hormuz or regional shipping lanes, it could re‑emerge with leverage that the United States and its Gulf allies find intolerable.

U.S. policy faces a paradox. While the Trump administration’s “maximum pressure” campaign aimed to cripple Tehran, a cease‑fire that leaves Iran’s strategic capabilities intact threatens bipartisan consensus in Washington and alarms Israel and Gulf partners. Senator Lindsey Graham’s call for congressional oversight of any settlement underscores the political volatility.

Within Tehran, hard‑liners cite the war as proof that the West cannot be trusted, while moderates – exemplified by former foreign minister Mohammad Javad Zarif – push for a calibrated re‑engagement to stave off economic collapse. The internal power struggle will determine whether the pause becomes a stepping stone to genuine reform or merely a brief intermission before renewed hostilities.

Ordinary Iranians bear the heaviest burden: destroyed infrastructure, internet blackouts, and a near‑collapsed economy. Their appetite for peace may be the most fragile variable of all, and arguably the least likely to translate into lasting stability.
