Tillerson says Iran nuclear deal is same 'failed approach' that led to North Korea

Tillerson made the comments at the State Department Wednesday afternoon.

"An unchecked Iran has the potential to travel the same path as North Korea and take the world along with it," Tillerson said, later adding that the current nuclear agreement "only delays their goal of becoming a nuclear state."

"The Trump administration has no intention of passing the buck to a future administration on Iran," Tillerson said.

The Iran deal, formally known as the Joint Comprehensive Plan of Action or the JCPOA, "is another example of buying off a power who has nuclear ambitions," Tillerson said. "We buy them off for a short period of time and then someone has to deal with it later. We just don't see that as a credible way to be dealing with Iran."
