In a major speech on Thursday, Iran’s supreme leader, Ayatollah Ali Khamenei, issued what amounted to a warning of things to come. He called the U.S. account of Iranian obligations under the nuclear framework agreement “faulty, incorrect and contrary to the substance of the negotiations,” effectively stating that Tehran offered exactly zero concessions at Lausanne. “Nothing has happened yet,” he said. Adding insult to injury, he noted that any “unconventional inspection or monitoring which would make Iran into a special case would not be acceptable” in a final deal.
