A senior adviser to Iran’s supreme leader Mojtaba Khamenei has claimed that Tehran has the legal right to manage the Strait of Hormuz, one of the world’s most strategically important oil shipping routes, as nuclear talks between Iran and the United States enter a critical phase.Mohsen Rezaei, the former head of Iran’s Islamic Revolutionary Guard Corps (IRGC) and an adviser to supreme leader Ali Khamenei, said on Sunday that Iranian control of the strait would “ensure national security” and end what he described as “50 years of insecurity in the Gulf”, according to Iran’s Tasnim news agency.Rezaei also indicated that Tehran is simultaneously conducting military preparations and diplomacy amid the current tensions.“Today our fighters have their hands on the trigger and our negotiators are working to secure the rights of the Iranian people,” he said. “The war is being managed on both fronts.”The comments come as US-Iran talks appear to be approaching a crucial stage. US President Donald Trump said via Truth Social on Saturday that “the final aspects and details of the deal are still under discussion, and will be announced soon.”According to multiple US and Iranian media reports, negotiators are working on a proposed memorandum that could create a framework to end months of conflict, reopen the Strait of Hormuz and potentially ease restrictions on Iranian shipping.Reports suggest that the issue of Iran’s highly enriched uranium stockpile will be addressed separately within a period of 30 to 60 days.US Secretary of State Marco Rubio, speaking during his visit to India, indicated that further progress in the talks could emerge by Sunday.The Strait of Hormuz remains one of the world’s most important maritime chokepoints, where a significant portion of global oil and gas shipments pass through the narrow waterway linking the Persian Gulf to international markets.
