Kerry on Iran: 'It's not based on trust'

Secretary of State John Kerry says the Iranian nuclear deal is based on verification, not trust with Iran.

“Everybody has a right to be skeptical because there are indications that there are people in Iran who have wanted to pursue a weapons program, Kerry said in an interview aired Sunday on CBS’s "Face the Nation." “That's why we don't take anything at face value. That's why you don't take it for granted.”

Asked if he were skeptical whether Iran would actually comply with the signed deal, Kerry said trust wasn’t necessary, and no one was expecting Iran to “turn over a new leaf.”

“There's nothing built on trust,” Kerry said. “You don't have to trust the people you're dealing with, you have to have a mechanism put in place whereby you know exactly what you're getting and you know exactly what they're doing."

Kerry compared the negotiations to dealing with the Soviet Union in terms of a lack of trust between negotiators.

"We've done arms control agreements in other parts of the world," Kerry said. "You don't trust. It's not based on trust. It's based on verification."
