Vance says "ball is in the Iranian court"

Vice President JD Vance told Fox News in an interview Monday that the U.S. made its red lines clear in talks with Iran, and that it's now up to Tehran to take action. 

"I really think the ball is in the Iranian court, because we put a lot on the table. We actually made very clear what our red lines were," Vance said. 

Vance said the U.S. is willing to be accommodating, but Iran cannot have the ability to enrich uranium and that the "nuclear dust" needs to be removed from Iran, preferably by the U.S. Another red line is nuclear weapons, the vice president said.

"It's one thing for the Iranians to say that they're not going to have a nuclear weapon. It's another thing for us to put in place the mechanism to ensure that's not going to happen," Vance said.

On the Strait of Hormuz, Vance said there's been an "uptick in traffic coming through the strait," but that it hasn't been fully reopened. The vice president added that if the Iranians don't make progress on the vital waterway, it will "change the negotiation." 

Vance also said Iran "tried to move the goalposts" on the strait during the talks in Pakistan. He said the U.S. now has the cards, militarily and economically, in the Strait of Hormuz, and it's up to the Iranians to decide how they're going to move forward.
