Could 2013 be the year we get to "yes" with Iran?

Within a couple of weeks, President Obama will have a new national security team in place. The Senate has confirmed John Kerry as secretary of state. The Senate also is likely to confirm Chuck Hagel as secretary of defense, despite a biased and unfounded smear campaign. Jack Lew will soon be considered by Congress for treasury secretary, and John Brennan for CIA director.

One of the biggest national security challenges the president and his new team will face over the next few years is the threat that Iran may build a nuclear weapon. Iran's leader, Ayatollah Ali Khamenei, has not yet made the decision to pursue nuclear weapons, according to U.S., European and Israeli intelligence agencies. So what are the chances the president's new team will be able to help Obama arrive at a diplomatic agreement with Iran before Khamenei decides to build a nuclear bomb?
