In March, Pyongyang said it would suspend its nuclear and missile testing programs if the U.S. would sit down and discuss how to improve relations. President Donald Trump and North Korean leader Kim Jong Un did just that. At that time Pyongyang said it would completely give up its nuclear program if it were to get security guarantees. Skeptics found that hard to believe. But on this program, Ambassador Joe Detrani, a former U.S. official who has sat across the negotiating table from North Korean representatives, tells us that making a nuclear deal is going to be difficult, but it can be done.
