President Barack Obama's national security adviser says the door remains open for Iran to work with other countries on its nuclear program. But James Jones also says the "picture is not a good one."
Jones says the clock is ticking toward the end of the year. That's when Obama has said it would be clear whether Iran was ready to work with the United States, other U.N. Security Council members and Germany to assure the world it was not trying to build a nuclear weapon.
So far, Iran has rejected calls to enter negotiations, and Obama is believed preparing to seek harsher international penalties against Iran. Jones said "the door remains open" for Iran to change course.
Iran says its nuclear program is peaceful and it has a right to enrich uranium to produce fuel for nuclear reactors to generate electricity.
Jones appeared on CNN's "State of the Union."
