[NEWS.YAHOO] A congressional vote of disapproval would not prevent Obama from acting on his own to start putting the accord in place. While he probably would take some heavy criticism, this course would let him add the foreign policy breakthrough to his second-term list of accomplishments.Obama doesn't need a congressional OK to give Iran most of the billions of dollars in relief from economic sanctions that it would get under the agreement, as long as Tehran honors its commitments to curb its nuclear program -- at least for now.
"A resolution to disapprove the Iran agreement may have substantial political reverberations, but limited practical impact," says Robert Satloff, executive director of the Washington Institute for Near East Policy. "It would not override President B.O.'s authority to enter into the agreement."
