Iran Warns US of ‘Unforgettable Lessons’ as MoU Collapse Deepens Regional Crisis
Tehran declares the memorandum of understanding “over” following mutual accusations of violations, while reports suggest Houthi forces may disrupt Red Sea shipping lanes in support of Iranian operations.

Iran’s Supreme Leader, Mojtaba Khamenei, has issued a stark warning to the United States, stating that American forces will face “unforgettable lessons” if attacks on Iranian territory persist. In a written statement read on state television, Khamenei accused Washington of repeatedly violating a memorandum of understanding (MoU) mediated by Qatar and Pakistan, describing the accord as effectively terminated due to mutual breaches.
The statement characterised US foreign policy as driven by “bullying, hegemonism and savagery,” and explicitly dismissed the validity of President Donald Trump’s signature on the agreement as “utterly worthless and invalid.” Khamenei asserted that the United States had “revealed its true face,” exposing what he described as deceitfulness and unreliability, while calling on the Iranian public to remain vigilant and trust the leadership to protect the nation from what Tehran views as an existential threat.
The diplomatic breakdown follows a significant escalation in military operations. The United States has intensified strikes against Iranian civilian infrastructure, including bridges, railway lines, and water desalination plants. In retaliation, Iranian forces have successfully targeted civilian infrastructure in Kuwait, prompting Kuwaiti authorities to urge citizens to ration electricity as the conflict expands beyond bilateral borders.
Both Tehran and Washington have formally declared the recent MoU “over” following these mutual accusations of violations. The US-Israeli war on Iran, which commenced in February, has seen no signs of de-escalation from the Trump administration, despite behind-the-scenes efforts by regional countries to broker an end to the hostilities. The conflict has become increasingly unpopular within the United States, with reports indicating it is inflicting tangible economic harm on American citizens.
Compounding the regional instability, reports suggest that the Houthis in Yemen may close the Bab al-Mandeb gateway to the Red Sea in support of Iran. Such a move would further destabilise global energy markets, potentially driving up inflation and applying additional pressure on the US administration to halt its military campaign.
