Reporter but a weary secretary of state kerry, sharply rejecting the idea he got taken to the cleaners. Did iran win here . Not not no. Those people who criticize it like that, they dont have an alternative. This is the safest, best way to make the world safer by reducing the ability of iran to be able to have a nuclear weapon.
