Iran on Monday formally rejected a US-mediated 45-day ceasefire proposal and countered with comprehensive demands including a permanent end to the five-week conflict, guarantees against future attacks, and reconstruction assistance. The rejection came hours before President Trump's extended deadline for reopening the Strait of Hormuz reaches its critical Tuesday 8 PM EDT expiration point.
Tehran's counter-proposal, comprising 10 clauses, escalates beyond temporary de-escalation by demanding an end to regional conflicts, a protocol for safe Strait passage, lifting of sanctions, and infrastructure reconstruction support. The rejection occurred as Pakistan, Turkey, and Egypt intensify urgent mediation efforts to prevent US strikes on Iranian energy infrastructure when Trump's ultimatum expires.
Escalating demands amid conflict
Iran's Revolutionary Guards stated the Strait of Hormuz "will never return to its former state," according to sources familiar with Iranian positions. This declaration directly contradicts Trump's core demand for unconditional reopening of the waterway that carries approximately one-fifth of global oil and natural gas supply. The US-mediated proposal called for a 45-day initial ceasefire followed by negotiations addressing Iran's uranium stockpile and permanent Strait reopening.
Trump threatened to "rain hell on Tehran" if Iran fails to reopen the Strait by Tuesday's deadline. The President has previously warned of strikes targeting power plants, bridges, and civilian infrastructure—threats that the International Committee of the Red Cross and former US National Security Council legal advisors warned could constitute war crimes under international humanitarian law.

Critical 24 hours ahead
The Strait of Hormuz has been effectively closed since early March, disrupting global energy markets and driving oil prices sharply higher. Iran has maintained the waterway remains open except to "enemy" vessels while implementing transit fees, a formulation that falls short of Trump's demand for full unconditional reopening to commercial shipping.
The Tuesday deadline represents the third extension of Trump's original threat, creating a critical test of whether coercive diplomacy can compel Iranian compliance or whether the pattern of postponements signals both sides are managing perceptions while preparing for resumed military operations. The conflict began February 28, 2026, with US and Israeli airstrikes on Iran's nuclear program and has expanded to include attacks on energy infrastructure, maritime facilities, and civilian areas across the region.
