[Kim Jong Un is] controlling the clock. There was a momentum toward a [U.S.] military option, but what the Olympics thaw or propaganda or pageantry did was it slowed time down. The more there’s inter-Korean engagement, the more wind is taken out of the sails of preemptive or preventive strikes on North Korea. [Kim wants to convey] his mastery of the situation. [But he is unlikely to release his nuclear arsenal.] It’s in Kim Jong Un’s DNA to pursue nuclear weapons. His grandfather wanted it. His father wanted it.
