Mojtaba Khamenei brands US 'Great Satan', slams Trump deal as 'worthless' in furious rant
TEHRAN, IRAN: Mojtaba Khamenei on Saturday, July 18, launched a furious attack on the United States, branding Washington the “Great Satan” and declaring that Donald Trump’s signature is “worthless” after Iran accused the US of repeatedly violating a deal between the two countries.
In a sharply worded message, Iran's new supreme leader accused the Trump administration of coercion, brutality, and dishonesty, claiming the latest US actions had exposed the “true face” of America.
His remarks came as the fragile understanding between Washington and Tehran appeared to unravel amid a fresh wave of US strikes and Iranian retaliation.
The repeated breaches of the agreement by the Great Satan [the US] regarding the MOU signed by the Presidents of Iran and the US have once again laid bare a fundamental truth: the signature of the US President is utterly worthless and devoid of credibility.

Mojtaba Khamenei unleashes attack on Trump
In a lengthy post on X, Mojtaba Khamenei said the latest escalation had exposed what he described as the “true, unmasked face” of the "Great Satan" United States.
Referring to what he called repeated breaches of an agreement between Iran and the US, Mojtaba Khamenei wrote that the “signature of the US President is utterly worthless and devoid of credibility.”
He went on to accuse Washington of following a doctrine built on “coercion, totalitarianism, and brutality,” describing the latest developments as another example of American “dishonesty, irrationality, unreliability, and malicious nature.”

Khamenei said the alleged breaches had once again demonstrated that the United States could not be trusted, while praising what he described as the “valor of the Islamic fighters” and the courage of people in Iran's southern regions.
He also urged Iranians to remain “vigilant and active” to protect the interests of what he called “Islamic Iran.”
The post came as the US-Iran conflict continues to escalate and Washington maintains its military campaign against Iran.
Today, the Great Satan has once again revealed its true, unmasked face, so that this dark episode of criminality and broken promises serves as yet another indisputable testament to the US’s dishonesty, irrationality, unreliability, and malicious nature.
