JD Vance has canceled his trip to Switzerland which was meant to lead a new round of talks with Iran about its nuclear program.

The White House said in a statement that plans for the technical talks have not been finalized, and said the US delegation has been prepared to depart at the first available opportunity. 

'As the Vice President said at his press conference, the plans for the upcoming technical talks have not been finalized, and the US delegation has been prepared to depart at the first available opportunity,' they said. 

'But the logistics of these negotiations have never been simple or predictable. As of now the Vice President is not departing tonight. We will let you know as soon as we have a concrete update about next steps.' 

It comes as Donald Trump has been touting the prospects of his deal to end the Iran War, which he claimed forced Tehran into an 'unconditional surrender' Thursday.

Vance was set to spend Friday through Sunday at the luxurious Burgenstock Resort in the Swiss Alps with Middle East envoy Steve Witkoff and Presidential son-in-law Jared Kushner for the talks.

They were supposed to be set intensive negotiations with Iranian delegates and mediators from Pakistan and Qatar.

The Iranian delegation was slated to include the Speaker of the Parliament Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, both key figures in the move toward a broader settlement.

The administration has positioned Vance as the primary lead of these negotiations since April, when he led the US team during preliminary talks in Islamabad.

Yet, as the delegation prepares for the technical phase of the agreement, the rhetoric has reached a fever pitch.

At the last day of the G7 summit in Evian-les-Bains, France, President Trump offered a blunt, characteristic assessment of his Vice President's role in the peace process.

'If it works out, I'm going to take the credit. If it doesn't work out, I'm blaming JD,' Trump joked to reporters. 'You better be careful, JD. He's going to turn his plane around and get the hell out of here.'

While the initial plan had earmarked Friday for a formal, in-person signing ceremony, the timeline was abruptly accelerated.

Trump signed the memorandum of understanding during a candlelit dinner outside Paris late Wednesday, while Iranian President Masoud Pezeshkian finalized the document remotely.

With the President's lighthearted threat hanging in the air, the Vice President is expected to deliver results - or face the consequences of the administration's most intense diplomatic gamble. 

This is a developing story.
