Arizona Tribune - Iran upbeat after US talks but Vance says 'red lines' not met

The Omani-mediated talks were aimed at averting the possibility of US military intervention to curb Iran's nuclear programme, weeks after the cleric-run state killed thousands of people as it crushed mass demonstrations.

Iran's supreme leader had warned earlier in the day that the country had the ability to sink a US warship recently deployed to the region, after President Donald Trump alluded to "consequences" should the two sides fail to strike a deal.

"Ultimately, we were able to reach broad agreement on a set of guiding principles, based on which we will move forward and begin working on the text of a potential agreement," Foreign Minister Abbas Araghchi told state television after Tuesday's talks, which he described as "more constructive" than the previous round earlier this month.

He added that once both sides had come up with draft texts for an agreement, "the drafts would be exchanged and a date for a third round (of talks) would be set".

In Washington, Vance also appeared to indicate that the United States preferred diplomacy but painted a more mixed picture.

"In some ways, it went well; they agreed to meet afterwards," Vance said in a Fox News interview.

"But in other ways, it was very clear that the president has set some red lines that the Iranians are not yet willing to actually acknowledge and work through," Vance told "The Story with Martha MacCallum" program.

"We're going to keep on working it. But of course, the president reserves the ability to say when he thinks that diplomacy has reached its natural end," Vance said.

- Key gaps -

Araghchi also acknowledged that it "will take time to narrow" the gap between the countries after the talks with Trump's friend and roving envoy Steve Witkoff and the president's son-in-law Jared Kushner.

Iran for years has been seeking relief from sweeping sanctions imposed by the United States, including a US-imposed ban on other countries buying its oil.

Omani Foreign Minister Badr Albusaidi said the two sides had made "good progress", but likewise cautioned "much work is left to be done".

Washington has ordered two aircraft carriers to the region as it piles on pressure. The first -- the USS Abraham Lincoln, with nearly 80 aircraft -- was positioned about 700 kilometres (435 miles) from the Iranian coast as of Sunday, satellite images showed.

Its location puts at least a dozen US F‑35s and F‑18 fighter jets within striking distance. A second carrier was dispatched over the weekend.

"A warship is certainly a dangerous weapon, but even more dangerous is the weapon capable of sinking it," Khamenei said in a speech Tuesday.

Iran has insisted the talks be limited to the nuclear issue, though Washington has previously pushed for other topics to be discussed, including Tehran's ballistic missiles programme and support for armed groups in the region.

- War games -

Iran has also sought to display its military might, with its Islamic Revolutionary Guard Corps beginning a series of war games Monday in the Strait of Hormuz to prepare for "potential security and military threats", state television said.

Iranian politicians have repeatedly threatened to block the strait, a strategic route for oil and gas.

A previous attempt at diplomacy collapsed last year when Israel launched surprise strikes on Iran in June, beginning a 12-day war that Washington briefly joined to bomb Iranian nuclear sites.

The West fears Iran's nuclear programme is aimed at making a bomb, which Tehran denies.

Iranian President Masoud Pezeshkian reiterated in an interview published Tuesday that Tehran was "absolutely not seeking nuclear weapons".

"If anyone wants to verify this, we are open to such verification to take place," he said.

Ali Fathollah-Nejad, director of the Berlin-based Centre for Middle East and Global Order, said Iran was faced with an "existential dilemma".

"Giving in to US demands could bring sanctions relief that it would desperately need to stabilise the regime and fund its repressive apparatus," he told AFP.

"However, any significant concessions on the nuclear, ballistic missile and regional proxies issues would sensitively undermine its ideological and military standing."
