U.S. sees signs Iran reconstituting nuclear sites, strikes failed to end threat

“The principle is very simple: Iran cannot have a nuclear weapon,” Vance tells reporters, a day ahead of talks in Geneva between US and Iranian delegations. “If they try to rebuild a nuclear weapon, that causes problems for us. In fact, we’ve seen evidence that they have tried to do exactly that.”

Vance notes that US President Donald Trump’s envoys Steve Witkoff and Jared Kushner are due to attend the negotiations with Iran on Thursday, adding that Trump wants to address the Iranian nuclear program “diplomatically, but of course the president has other options as well.”
