The best analysis of Mr. Khamenei’s demands comes from Yigal Carmon and Ayelet Savyon of the Middle East Media Research Institute. Demand One: The U.S. and Europe must completely lift, rather than temporarily suspend, their economic sanctions, putting an end to any possibility that penalties could “snap back” in the event of Iran’s noncompliance. Demand Two: Sanctions against Iran for its support of terrorism and its human-rights abuses must also go, never mind the Obama administration’s insistence that it will continue to punish Iran for its behavior.

Next Mr. Khamenei changes the timetable for Iran to ship out its enriched uranium and modify its plutonium reactor in Arak until the International Atomic Energy Agency gives Iran a pass on all “past and future issues (including the so-called Possible Military Dimensions or PMD of Iran’s nuclear program).” So much for the U.N. nuclear watchdog even pretending to monitor Iran’s compliance with the deal. He also reiterates his call for a huge R&D effort so that Iran will have at least 190,000 centrifuges when the nuclear deal expires.

“The set of conditions laid out by Khamenei,” Mr. Carmon and Ms. Savyon note in their analysis, “creates a situation in which not only does the Iranian side refrain from approving the JCPOA, but, with nearly every point, creates a separate obstacle, such that executing the agreement is not possible.”
