Iran’s Supreme Leader says U.S. breaches show Trump’s signature is ‘worthless’

Iran’s Supreme Leader ​Mojtaba Khamenei said ‌in a written ​statement on ⁠Saturday (July 18, 2026) that repeated U.S. breaches of a ‌memorandum of understanding ‌signed by ‌the Presidents ⁠of Iran ⁠and the United States had shown ​that President Donald ‌Trump’s signature was “utterly worthless and devoid of credibility.”

Washington ‌and Tehran have ​exchanged strikes after a ceasefire ⁠agreement fell apart last week, ‌raising fears of a return to all-out war.

Khamenei said the United ‌States should know ​that the Iranian nation and the “resistance ⁠front” had “unforgettable lessons” for ⁠it.
