U.S. and Iranian negotiators have reached a tentative agreement to extend the ceasefire by 60 days and start talks on Iran’s nuclear program. Speaking on the condition of anonymity, a U.S. official says President Donald Trump still needs to approve the memorandum of understanding. Trump and his team said from the start of the conflict and throughout the 3-month-old war that one of the prime reasons they undertook it was to ensure that Iran can never have a nuclear weapon. But Vance, touting what he said the war had accomplished, told reporters that, “We’re in a position where we could substantially set back their nuclear program, not just during the term of this president but over the long term.”
