White House Deputy Chief of Staff Stephen Miller has warned Iran of possible military action on an unprecedented scale if Tehran does not agree to a deal acceptable to the United States.

Speaking to Fox News, Miller said Iran’s current leadership faces a clear choice as negotiations remain stalled.

“This new team in Iran has a choice to make,” Miller said.

“They can either agree to a piece of paper that is satisfactory to the United States, or they can face a punishment from our military, the likes of which has not been seen in modern history. That’s the choice that they face,” he said, reports Al Jazeera.
