Trump's signature worthless, Great Satan US has repeatedly breached MoU: Mojtaba

Iran's Supreme Leader Mojtaba Khamenei on Saturday accused the US of repeatedly violating a Memorandum of Understanding (MoU). "The repeated violations...have once again proved to everyone the worthlessness and invalidity of [Trump's] signature," he said. Referring to US as the "Great Satan," he said the developments had exposed what he described as Washington's "true and unmasked face".
