Vice President Joe Biden earlier refused to confirm to CNN that the George W. Bush-era plan was being shelved.

But he did explain the logic of doing so, saying Iran — a key concern for the United States — was not a threat.

“I think we are fully capable and secure dealing with any present or future potential Iranian threat,” he told CNN’s Chris Lawrence in Baghdad, where he is on a brief trip.

“The whole purpose of this exercise we are undertaking is to diminish the prospect of the Iranians destabilizing that region in the world. I am less concerned — much less concerned — about the Iranian potential. They have no potential at this moment, they have no capacity to launch a missile at the United States of America,” he said.
