The Council on Foreign Relations (CFR) recently published a report about a grave, worsening global threat - the North Korean nuclear and missile programs. The bottom line: North Korea is rapidly becoming an existential threat to the U.S., and leaders can no longer wait for North Korea to meet conditions of sanctions designed to stop their nuclear program. On this episode of Target USA, former Georgia Sen. Sam Nunn, former Joint Chiefs of Staff Chairman Mike Mullen, CFR Project Director Adam Mount and former U.S. North Korea Mission manager Joseph DeTrani outline in detail the gravity of situation that worsens with each month.
