ALBAWABA — Iran’s Supreme Leader Mojtaba Khamenei wrote a detailed letter to the nation on Saturday, harshly criticising U.S. President Donald Trump for allegedly violating a bilateral memorandum of understanding previously signed with Iranian President Masoud Pezeshkian.

The statement, carried by Iran’s official state news agency IRNA, comes as regional tensions are high and the country is in mourning after the death of a senior leadership figure, dubbed by the Supreme Leader as the “Martyred Sayyid of Iran.” 

Khamenei Warns ‘Great Satan’ Not Credible 

Khamenei said in his speech that the accord’s failure was a predictable display of American diplomatic inconstancy. “The repeated breach of commitments by the Great Satan… has once again proved this truth to everyone: the worthlessness of the U.S. President’s signature and his lack of credibility,” Khamenei said, adding that “arrogance and brutality” are still the main features of Washington’s foreign policy.

The Supreme Leader cautioned the United States against continuing to escalate tensions in the region, warning of harsh retribution from Iranian forces and their regional allies. He cited recent actions of the "Axis of Resistance" and regional fighters in the south as a first warning to Washington. 

Domestic Unity Demands Amid Public Outcry 

A significant portion of the statement was devoted to internal stability, with Khamenei calling on the political factions and the general public to present a united front. He warned that the internal political struggles and social fragmentation would only give strength to foreign enemies.

Khamenei admitted some citizens and political commentators have offered “sincere criticisms” of the performance of state officials in all three branches of government amid growing domestic friction. He noted that such concerns were a sign of care for the state, but warned critics to be careful that their criticism is not targeted at innocent people, which he said could cost the nation divine blessings and that constructive criticism does not erode wider social cohesion or national unity. 

With thanks to Mourners and Allies 

Khamenei ended his speech by thanking the millions of Iranians who took to the streets during the recent mass funeral processions in Tehran, Qom and Mashhad. He also expressed formal gratitude to the state military and civil institutions, leading Islamic scholars and visiting delegations of various regional proxy movements who were present at the state ceremonies.
