An ultimatum to Iran from the United Nations Security Council: stop uranium enrichment within 30 days, or we will consider further action. The statement was the product of three weeks of arduous negotiations and compromises to win the approval of all 15 nations on the body.Diplomats say it sends a clear signal to Tehran. US ambassador John Bolton said: “There’s no ambiguity about what we’re waiting for. We’re waiting for the Iranians to do what they themselves said they were going to do and violated, and the obligations they undertook by being a member of the IAEA. What will the Iranians do in the next 30 days ? I certainly don’t know.” However the document made significant concessions to Russia and China. Theywanted to avoid language that could later be used to justify sanctions or a military strike. The IAEA, the UN’s nuclear watchdog, is to report back on Iran’s compliance with the Security Council’s demand.
