As negotiations between Iran and the five permanent members of the U.N. Security Council plus Germany continue, the President's National Security Adviser Susan Rice tells Wolf Blitzer that the deal on the table is "a good one." Specifically, she says, it will roll back the Iranian nuclear program in key respects over a six-month period while increasing the transparency surrounding the program so that the Iranians "can't sneak out or break out." And while some question easing sanctions on Tehran, Rice says the "sanctions architecture" will remain in place so that the relief will be "limited, modest, temporary, and reversible" - less than $10 billion in total.
