Christie won't pledge to undo Obama's Iran deal as president

“I’m not one of those guys who’s going to say to you, ‘on Day One I will abrogate the agreement,’” Christie said, noting that the American president could not just act alone when China, Russia, Germany, France and the United Kingdom are also parties to the deal, should one emerge. “On Day One, I will look into it and try to decide, depending upon where we are at that moment.”

As Christie was speaking, American and international negotiators were continuing talks in Vienna to complete the deal before this week’s deadline. Christie said he would have long since walked away from the table, arguing that Iran cannot be trusted to implement the agreement.

“If I was negotiating this deal right now, I would be gone,” he said. “I would be away from the table. I would be going back to our allies and saying these are not reliable negotiators on the other side—not the people we can count on to keep their word. They haven’t shown us that.”
