ERBIL, Kurdistan Region of Iraq – President Donald Trump said on Saturday that the United States still needs to deal with one or two sites in Iran despite having taken out much of its military, noting that negotiations with the Islamic republic are “not very reliable.” 

"We've knocked out their nuclear. We still have to take care of, I would say one or two sites, but we can do that in 10 minutes," Trump told reporters at his Florida residence.

He asserted that negotiations with the Islamic republic “were going fine, but you know they’re not very reliable.” 

His remarks come as Iranian Supreme Leader Mojtaba Khamenei has warned that Iran's military that any missteps by the US or Israel will be met with a response that is "geographically unrestricted," with Armed Forces Chief of Staff Ali Abdollahi affirming that his forces are "constantly updating our target database" in preparation.

On their list of targets, Trump listed Pickaxe Mountain, south of the Natanz nuclear complex, where nuclear material is believed to be stored. 

"You probably could look at Pickaxe Mountain, and you have to take care of that. We can do that all very quickly,” he said. 

On Saturday, Secretary of Iran’s Supreme National Security Council Mohsen Rezai on Saturday said that the "tone" of a letter he received from US Vice President JD Vance "has completely changed" compared to earlier diplomatic overtures.

"Their tone has completely changed, which is a good sign indicating that the Iranian nation has solidified its victory and power," Rezaei said. "Since they have not mentioned anything [details] from the letter, I will not say anything for now."

Trump has repeatedly claimed that February's US-Israeli war on Iran was instrumental in hampering Iranian ambitions to produce a nuclear weapon, despite Tehran's insistance that its proliferation efforts were for entirely civilian purposes.
