Donald Trump’s vow to renegotiate a deal with Iran is at a standstill

President Donald Trump has not renegotiated a deal with Iran after withdrawing the United States from an Obama-era nuclear pact.

The two countries are at loggerheads following Trump's exit in May from the international agreement to curb Iran's nuclear ambitions in exchange for lifting sanctions on the Islamic regime, though Trump has held the door open to future talks.

"I do believe that they will probably end up wanting to meet, and I'm ready to meet any time they want to," Trump said in a July press conference at the White House. "If we could work something out that's meaningful, not the waste of paper that the other deal was, I would certainly be willing to meet."

The president added that he would convene a meeting "anytime they want" — and without preconditions.

But hours later, Trump's secretary of state said the United States would engage in talks only under certain conditions.

"If the Iranians demonstrate a commitment to making fundamental changes in how they treat their own people, reduce their malign behavior, agree that it's worthwhile to enter into a nuclear agreement that actually prevents proliferation, then the president said he's prepared to sit down and have the conversation with them," Secretary of State Mike Pompeo told CNBC, alluding to a list of 12 criteria he previously outlined in May.

Iran's Supreme Leader Ayatollah Ali Khamenei rebuffed Trump's offer to meet, and accused the United States of having a history of negotiating in bad faith.

"Even if we ever — impossible as it is — negotiated with the U.S., it would never ever be with the current U.S. administration," Khamenei said.

Since then, tensions between the two countries have only escalated.

The Trump administration reimposed a second round of sanctions against Tehran in November, which Iranian President Hassan Rouhani said his country would "proudly break." A previous set of sanctions went into effect in August.

A new deal could eventually emerge. Given the current state of play, we rate this promise Stalled.
