Iran’s supreme leader has warned that the United States will face “unforgettable lessons” if its attacks on the country continue, accusing Washington of repeatedly violating last month’s memorandum of understanding (MoU) between the two sides, reports Al Jazeera.
A written statement attributed to Mojtaba Khamenei was read out on state television Saturday, declaring that US breaches of the accord proved President Donald Trump’s signature was “utterly worthless and invalid.”
“The repeated breach of agreements by the Great Satan vis-a-vis the accord has once again proven to all that the signature of the President of America is now utterly worthless and invalid, and that bullying, hegemonism and savagery are inseparable components of the American creed and doctrine,” the statement said.
It added, “Now that the American enemy is seeking to foment war and suffer heavier costs and further humiliation, it should know that the dear nation of Iran and the Resistance Front hold unforgettable lessons for it.”
The warning came as US forces escalated their campaign this week, striking civilian infrastructure in Iran, including bridges, railway lines, and water desalination plants. Tehran retaliated by hitting civilian facilities in Kuwait, prompting authorities there to urge electricity rationing.
The US‑Israeli war against Iran, which began in February, is viewed by Tehran’s leadership as existential. Despite mounting pressure from Washington, Iran has shown no sign of backing down, while regional states continue behind‑the‑scenes efforts to end the conflict.
Khamenei accused the US of exposing its “true face,” citing “deceitfulness, irrationality, unreliability and wickedness.” He urged Iranians to trust the leadership to safeguard the country and called on citizens to remain “vigilant” and “active” as fighting drags on.
Reports in recent days suggest the Houthis in Yemen may move to close the Bab al‑Mandeb strait, a key gateway to the Red Sea, in support of Iran. Such a move would further destabilize global energy markets, drive inflation, and increase pressure on Trump to halt attacks.
The war has become deeply unpopular in the United States, where it has inflicted economic damage.
The MoU, mediated by Qatar and Pakistan and signed last month, was intended to lay the groundwork for a permanent end to hostilities. However, both Tehran and Washington have since declared the agreement “over,” each accusing the other of violating its terms.
