President Trump flatly rejected Iran's formal response to a U.S. ceasefire proposal on Sunday, calling it "TOTALLY UNACCEPTABLE" and accusing Tehran's negotiators of playing games while American naval forces maintain a blockade of Iranian ports and tensions around the Strait of Hormuz show no sign of easing.
The dismissal came hours after Iran's state-run Islamic Republic News Agency confirmed that negotiators in Tehran had submitted their counter-proposal through Pakistani intermediaries. Pakistani Prime Minister Shehbaz Sharif said his government received the response, capping weeks of shuttle diplomacy involving Sharif, Pakistani army chief Asim Munir, and Pakistani Foreign Minister Ishaq Dar.
Trump made his position clear on Truth Social, as The Hill reported:
"I have just read the response from Iran's so-called 'Representatives.' I don't like it, TOTALLY UNACCEPTABLE!"
The president also accused Tehran of "playing games" with the United States. "They will be laughing no longer!" he wrote, AP News reported.
The Trump administration's reported proposal would have required Iran to agree to a moratorium on uranium enrichment in exchange for the United States dropping sanctions. Both sides would also lift restrictions on shipping through the Strait of Hormuz, the narrow waterway through which a significant share of global oil transits.
Axios reported Wednesday that the administration submitted a memo to Tehran outlining a 30-day timeline for reaching terms. The New York Post reported that Trump said Friday he expected a letter from Iran that night. "I'm getting a letter supposedly tonight. So we'll see how that goes," Trump told reporters. Secretary of State Marco Rubio added, "We should know something today."
What arrived Sunday fell far short of Washington's terms. The Wall Street Journal reported that Iran's response does not adhere to the administration's demands on uranium enrichment. Instead, Tehran's counter-proposal centers on a permanent end to fighting and a gradual, not immediate, reopening of the Strait of Hormuz.
Iran also proposed having some of its enriched uranium diluted, with the remainder transferred to a third country. But there was a catch: the uranium would be returned to Iran if negotiations fail or if the United States exits any future agreement. That reversibility clause alone should raise flags for anyone who watched Iran's behavior under the Obama-era nuclear deal.
Iranian state media went further, characterizing the U.S. proposal as tantamount to surrender. Tehran reportedly demanded war reparations, full sovereignty over the Strait of Hormuz, an end to sanctions, and the release of seized assets, Newsmax reported.
None of this happened in a diplomatic vacuum. The U.S. and Israel launched military operations against Iran on February 28. Since then, the Iranian military has threatened non-allied countries from transiting the Strait of Hormuz and laid mines in the waterway, actions that disrupted global shipping lanes and rattled energy markets.
The U.S. Navy responded with a blockade of Iranian ports beginning April 13, a pressure campaign designed to force Tehran back to the table. The Senate recently rejected a Democratic effort to restrict Trump's Iran war powers, giving the administration a freer hand to maintain that posture.
Iranian Foreign Minister Abbas Araghchi, who has led negotiations alongside Parliament Speaker Mohammad Bagher Qalibaf, struck a combative tone even before Trump's rejection landed. On Friday, Araghchi posted on X that Iran will "never bow to pressure" and that the Iranian military retains "1,000%" readiness to "defend our people" amid the discussions.
That is not the language of a government preparing to make concessions. It is the language of a regime posturing for a domestic audience while slow-walking diplomacy abroad.
Iran's counter-proposal follows a familiar playbook. Demand everything. Concede nothing of substance. Attach reversibility clauses to any nuclear commitment. Insist on reparations. Wrap it all in sovereignty language designed to make any compromise politically impossible for the other side.
The enriched uranium proposal is a case study. Diluting some material while shipping the rest to a third country sounds like progress, until you read the fine print. If the deal collapses or the U.S. withdraws, the uranium comes home. Tehran gets a free option: cooperate when convenient, reclaim fissile material when it isn't.
Trump has made clear he sees through the maneuver. He has reiterated threats to resume full-scale bombing if Iran does not accept terms to reopen the Strait of Hormuz and roll back its nuclear program. Fox News covered Trump's hard line on its "Big Weekend Show" segment Saturday, framing the standoff as a test of whether diplomacy has any remaining runway.
The administration's earlier declaration that Iran hostilities were "terminated" as the War Powers clock hit 60 days added a layer of legal and strategic complexity. That move bought time. Whether it bought enough depends on what comes next.
Pakistan's involvement as mediator is itself notable. Prime Minister Sharif, army chief Munir, and Foreign Minister Dar have shuttled between Tehran and Washington in an effort to broker terms. Sharif confirmed Sunday that his government received Iran's response, positioning Islamabad as a credible go-between.
But mediation only works when both parties want a deal. Iran's maximalist counter-proposal, reparations, full sovereignty over the strait, sanctions relief, asset release, reads less like a negotiating position and more like a wish list designed to be rejected. If Tehran's goal is to run out the clock while maintaining the appearance of engagement, Pakistan's diplomats are carrying water for a process that may already be hollow.
The Hill reached out to the White House for comment on Trump's statement. No response was reported.
Meanwhile, the broader Washington landscape remains charged. Trump has simultaneously been managing political confrontations on the domestic front, including clashes with congressional Democrats, while navigating legal challenges to his trade agenda. The Iran standoff adds a volatile foreign-policy dimension to an already crowded plate.
Just The News reported that Iran wants any talks focused on a permanent end to the wider regional conflict, not the narrower terms Washington put forward. That gap, between a limited ceasefire framework and a sweeping regional settlement, may prove unbridgeable under current conditions.
The 30-day timeline Axios reported is already ticking. The naval blockade continues. Mines remain in the Strait of Hormuz. And Iran's foreign minister is publicly boasting about military readiness while his negotiators submit proposals the president of the United States won't even entertain.
The open questions are significant. What specific terms in Iran's response triggered Trump's rejection? Will Tehran submit a revised proposal, or was this response designed to fail? And if diplomacy stalls, does the administration follow through on its threat to resume bombing?
For now, the facts point in one direction. Iran responded to an American offer with demands for reparations, reversible nuclear commitments, and full sovereignty over a waterway it has been mining for months. Trump called it unacceptable. On that point, the evidence is on his side.
When a regime lays mines in an international shipping lane and then demands sovereignty over that same lane as a condition of peace, it is not negotiating. It is stalling. And stalling, in the Middle East, has a cost that rarely falls on the people doing it.
