Our diplomacy is at work with respect to Iran, where, for the first time in a decade, we’ve halted the progress of its nuclear program and reduced its stockpile of nuclear material. Between now and this spring, we have a chance to negotiate a comprehensive agreement that prevents a nuclear-armed Iran, secures America and our allies -- including Israel, while avoiding yet another Middle East conflict. There are no guarantees that negotiations will succeed, and I keep all options on the table to prevent a nuclear Iran.
