Speaking at an event in Budapest during his trip to Hungary, Vance said a deal ​was possible if Iran negotiated sincerely, but cautioned that ​while some parts of the Iranian system were approaching ⁠the talks constructively, others were not. He described the ​situation as a “fragile truce.”

“The President of the United States has told ​me, and he’s told the entire negotiating team, Secretary of State, the special envoy Steve Witkoff, he said, go and work in good faith ​to come to an agreement,” Vance said.

“He’s impatient. He’s impatient ​to make progress. He has told us to negotiate in good faith, and ‌I ⁠think if they negotiate in good faith, we will be able to find a deal. But that’s a big if, and ultimately, it’s up to the Iranians how they negotiate. I ​hope they make ​the right ⁠decision,” Vance said.

The United States and Iran have agreed to a two-week ceasefire brokered by Pakistan, potentially ​halting a six-week-old war that has killed thousands, ​spread across ⁠the Middle East and caused unprecedented disruption to the world’s energy supplies.

Trump announced the agreement late on Tuesday, just two hours ⁠before ​a deadline he had set for Iran ​to open the blockaded Strait of Hormuz or face the destruction of its “whole ​civilisation”.
