Former deputy national security advisor Victoria Coates discusses Iran's response to President Donald Trump's bid for nuclear talks on 'Sunday Morning Futures.' Trump has sent an ultimatum-style letter to Iran's Supreme Leader Ali Khamenei, seeking a diplomatic settlement to prevent Iran from becoming a nuclear state. However, Khamenei rejected the letter and warned that the U.S. would raise new demands, including restrictions on defense capabilities and international influence. Russia's strategy for helping the U.S. negotiate with Iran seems to be allowing a U.S.-Israel strike to destroy Iran's nuclear facilities, easing international pressure. Russia's influence over Iran is undeniable, and if the regime survives and sanctions ease, Iran could access $100 billion annually to rebuild even stronger.
