Trump’s Signature Is Worthless’: Iran’s Supreme Leader Condemns US Over Broken Deal

Iran’s Supreme Leader, Mojtaba Khamenei, has sharply criticized the United States, declaring that repeated American violations of a recently signed agreement demonstrate that President Donald Trump’s signature is “worthless” and cannot be trusted, as tensions between Tehran and Washington continue to escalate.

In a written statement released on Saturday, Khamenei accused the United States of failing to honor commitments made under a memorandum of understanding reached last month, saying the agreement had effectively been rendered meaningless by continued U.S. military operations against Iran. He argued that Washington’s actions proved any promises made by the Trump administration lacked credibility.

The remarks come amid a dramatic deterioration in relations between the two countries following the collapse of a fragile ceasefire. Over the past week, the United States has carried out successive rounds of airstrikes targeting Iranian military infrastructure, while Iran has responded with missile and drone attacks against U.S. and allied facilities across the Middle East, raising fears of a wider regional conflict.

Khamenei warned that Iran and what he described as the “resistance front” would ensure the United States remembered the consequences of its actions. While he did not outline specific retaliatory measures, his statement suggested Tehran would continue resisting what it considers American aggression rather than return to negotiations under the current circumstances.

The memorandum of understanding, brokered in June with international mediation, had been intended to halt hostilities, reopen the Strait of Hormuz to commercial shipping and create a framework for broader peace negotiations. However, disagreements over maritime security, military activity and mutual accusations of violations quickly undermined the agreement, leading to renewed fighting.

Iranian officials have repeatedly argued that the United States breached both the spirit and the terms of the agreement by continuing military operations and issuing threats against Tehran. Washington, meanwhile, has maintained that its strikes were a response to Iranian attacks on commercial shipping and U.S. interests in the Gulf, insisting that the operations are aimed at protecting international navigation and regional security.

The renewed confrontation has also heightened concerns over global energy markets. The Strait of Hormuz, through which roughly one-fifth of the world’s seaborne oil passes, remains a focal point of the dispute. Continued military activity in and around the strategic waterway has disrupted shipping and contributed to volatility in global oil prices.

Diplomatic efforts to restore dialogue have so far made little progress. Several regional governments have urged both Tehran and Washington to return to negotiations, warning that continued escalation could destabilize the wider Middle East and further disrupt international trade and energy supplies.

Analysts say Khamenei’s latest statement reflects deepening mistrust between the two adversaries and underscores the increasingly hostile rhetoric accompanying the ongoing military confrontation. With both sides continuing to exchange strikes and accusations, prospects for reviving the collapsed agreement appear increasingly uncertain, raising the risk of a prolonged and broader regional conflict.
