Supreme Leader Ayatollah Ali Khamenei approved a memorandum of understanding with the U.S. on June 18, 2026 [1].
The move signals a significant shift in Tehran's diplomatic posture, as the Supreme Leader has historically maintained a deep skepticism of agreements with Washington.
In a message addressed to the Iranian people, Khamenei said that engaging in negotiations does not mean accepting the view of the enemy [2]. He said that his approval of the memorandum followed specific assurances from President Masoud Beshkin. According to the message, Beshkin pledged that the agreement would safeguard the rights of the Iranian people, and the "resistance front" [2], [3].
Khamenei said that he was not initially satisfied with the agreement but agreed to it after the pledges from Beshkin [4]. The Supreme Leader said the U.S. approach to the deal was a result of weakness, stating that Donald Trump used every available tool from a position of deficiency to reach the memorandum [5].
The announcement was disseminated through Iranian state media and picked up by several regional news outlets [2]. The memorandum aims to establish a framework for cooperation or conflict mitigation, though the specific terms of the agreement remain under discussion among regional observers [2], [3].
Khamenei said that the approval was contingent on the protection of Iranian sovereignty. He said the guarantees provided by the presidency were the deciding factor in his decision to move forward with the document [3], [6].
“"I was not satisfied with the agreement, but I agreed to it after pledges from Beshkin"”
This development suggests a pragmatic pivot by the Iranian leadership to alleviate pressure through a formal agreement, while simultaneously maintaining a narrative of strength. By framing the U.S. as acting from a 'position of deficiency,' Khamenei attempts to preserve his ideological standing with hardliners while granting the presidency the diplomatic space to negotiate.
