The U.S. is back in negotiations for a nuclear deal with Iran, years after former President Donald Trump withdrew the country from the Joint Comprehensive Plan of Action (JCPOA), which had been meant to curtail the Middle Eastern nation's nuclear ambitions. Former State Department senior advisor to the George W. Bush and Trump administrations, Christian Whiton, joined Cheddar News Wrap to discuss. “It appears to be very similar to the original JCPOA, which does put some constraints on Iran's nuclear program, but also has sunset provisions, including some that in the original plan were expected to take effect in 2025," he said. "And so, if we just reenter that plan, really it just buys perhaps a few years of slowing down, stopping, whatever you want to say, Iran's nuclear program."
