BURGENSTOCK, Switzerland -- What was supposed to be the first face-to-face technical engagement between the US and Iran after their surprise memorandum of understanding (MOU) has instead become an early test of whether the fragile diplomatic opening can survive the pressures of a wider regional war.The talks, expected to take place at Switzerland’s Burgenstock resort with Qatar and Pakistan helping facilitate, were abruptly postponed on June 19, just hours after senior officials had begun signaling to reporters that the meeting was expected to go ahead.Then the plans unraveled.
Vice President JD Vance, who had been expected to lead the US delegation, delayed his trip.Switzerland’s Foreign Ministry confirmed the talks were off -- at least for now.And Iran declared there was “no urgency” for immediate engagement, arguing the initial memorandum had already been digitally signed and that the next phase would depend on the implementation of agreed terms.The message from all sides was deliberate: This is a delay, not a collapse.“Postponement is the critical word here, rather than cancellation,” Dr. Gorana Grgic, head of the Global Security Team at Zurich’s Center for Security Studies, told RFE/RL.Swiss officials appear to share that view. The Foreign Ministry said preparatory work at Burgenstock is continuing, suggesting all sides still intend to return to the table.That matters because Switzerland has long played a unique role in US-Iran diplomacy. Since formal ties were severed after the 1979 Iranian Revolution, Bern has served as Washington’s protecting power in Tehran and as a key channel for communication.Grgic said Switzerland’s role is often misunderstood.Diplomatic Backchannels“Switzerland is acting as a hub for negotiation,” she said, stressing that Bern functions less as a direct mediator and more as a facilitator -- hosting talks, maintaining channels, and enabling backchannel contacts.Those backchannels remain central. “There are a lot of back channels that lead both to Washington and Tehran,” Grgic said. “And they have been active all throughout this process.”
