Iran’s chief negotiator, Mohammad Bagher Ghalibaf, issued a stark ultimatum on Tuesday, insisting that the United States must accept Tehran’s 14-point peace proposal or face repeated failure. Writing on X, Ghalibaf declared there was “no alternative” to recognising the rights of the Iranian people as outlined in the document, and warned that the longer Washington delayed, the higher the cost would be for American taxpayers. The ultimatum came just hours after President Donald Trump had dismissed the Iranian counteroffer as “total garbage”, describing the ceasefire in place since 8 April as surviving on “life support”. The war, triggered more than two months ago by US-Israeli strikes against Iran, has since convulsed the Middle East and disrupted global energy markets, yet neither side appears willing to step back from the brink.

Viewed from Tehran, the 14-point plan represents a maximalist negotiating position that enshrines Iran’s right to continue enriching uranium and to retain its existing stockpile. Senior Iranian officials have made clear that any permanent halt to enrichment or a requirement to hand over enriched material to the United States is a non-starter. This red line cuts directly against Washington’s long-standing demand for a verifiable end to Iran’s nuclear activities, a position that has been reinforced by Israel and by Gulf Arab states wary of Iranian dominance. Analysts in London note that the deadlock mirrors the pattern of past nuclear talks: a cycle of brinkmanship in which each side tests the other’s resolve before eventual retreat or escalation.

Pakistan has been mediating the negotiations, but the process remains stalled after an initial round last month failed to yield a breakthrough. Both capitals continue to issue public threats while privately signalling reluctance to resume full-scale hostilities. The economic toll is already severe: oil prices have oscillated wildly, and global shipping lanes remain under strain. For the Trump administration, the political calculus is complicated by the approach of midterm elections, making a costly new war domestically unpalatable, yet a humiliating diplomatic climb-down equally unattractive.

Looking ahead, the standoff may be unsustainable. The ultimatum leaves little room for face-saving compromise, and the coming days will test whether the Pakistani mediation can craft a formula that allows each side to claim victory without triggering renewed conflict. Foreign ministries across Europe are quietly urging restraint, but with both Washington and Tehran having painted themselves into rhetorical corners, the most likely near-term outcome is a further war of attrition through proxies and economic pressure, punctuated by periodic crises that keep the world on edge.
