Hats off to Assistant U.S. Secretary of State Christopher Hill! It’s not exactly clear what he told (or promised) North Korean officials during his first-ever surprise visit to Pyongyang last week – or if the mere continuation of the long sought after one-on-one direct dialogue was sufficient – but Pyongyang has finally agreed to honor its commitment to begin the denuclearization process. As spelled out in the Feb. 13, 2007 Six-Party Talks “action for action” agreement, International Atomic Energy Agency (IAEA) officials are returning to Pyongyang to begin the process of shutting down and sealing the DPRK’s nuclear facilities at Yongbyon.
