US and Iran edge closer to nuclear deal with key terms still unresolved

Iran and the US are advancing discussions on a memorandum of understanding (MOU) regarding Iran's nuclear programme. The talks involve confidential proposals to outline implementation steps, verification measures, and timelines. Iran's lead negotiator has publicly defended the agreement's terms. Mohammad Bagher Ghalibaf stated that Iran would dilute, not surrender, its highly enriched uranium stockpile. He emphasised that the country’s nuclear activities, including civilian uranium enrichment, would continue under the MOU. According to him, the accord preserves Iran’s right to a peaceful nuclear programme under international law.

Some additional understandings have been documented, though Iran has not formally signed them. The most difficult issues—such as limits on Iran’s nuclear work and sanctions relief—still need further negotiation. Both sides acknowledge that the accord remains unfinished, with political and security risks unresolved. The proposals now include specific details on implementation and verification. Iran insists it has not relinquished any sovereign rights. The process continues as both parties work to address outstanding disagreements.
