Iran-US Talks: Strait of Hormuz Tensions Fail to Derail Constructive Geneva Nuclear Session

Even as Iran announced military exercises near the strategically vital Strait of Hormuz and its Supreme Leader issued threatening remarks toward US warships, nuclear diplomacy between the two countries continued to move forward on Tuesday. The second round of indirect talks in Geneva ended with agreement on guiding principles and a commitment to hold a further session within two weeks.
Iran’s Foreign Minister Araghchi offered a measured but genuinely positive assessment of the talks, which lasted roughly three and a half hours and were facilitated by Omani intermediaries. He said the atmosphere had improved significantly compared to the first round and that both sides had made real progress, while acknowledging that bridging their remaining differences would take time.
The substance of the talks revolved around Iran’s nuclear activities — its enrichment programme, its stockpile of near-weapons-grade uranium, and the terms under which IAEA inspectors could return to full operation at damaged nuclear sites. Iran offered to dilute its 60% enriched uranium and expand IAEA cooperation, presenting these steps as significant gestures of goodwill.
The central unresolved issue was the US demand that Iran halt all domestic uranium enrichment — a demand Tehran has consistently rejected as an infringement on its sovereign rights. Iran similarly refused to include its ballistic missiles or its regional relationships in the scope of any nuclear agreement, limiting the potential deal to nuclear programme constraints and verification mechanisms.
The regional military context remained volatile throughout. The US naval buildup in Gulf waters continued, and Iran’s announcement of live-fire exercises in the Strait of Hormuz raised concerns in shipping markets worldwide. Domestically, Iran remained roiled by the aftermath of recent protests, with over 10,000 demonstrators facing prosecution and the government managing the political fallout from acknowledged civilian deaths.
