Yonhapnews Agency on the new PACOM Commander pulling no punches about the unpredictability of North Korea (emphasis added):

On March 26, 2010, the 1,200-ton naval corvette sank in the Yellow Sea, killing 46 South Koreans. An international investigation found that Pyongyang had torpedoed the ship, though the belligerent regime has denied responsibility. The hull of the vessel is on display at the fleet’s headquarters.

I believe North Korea is dangerous, it’s unpredictable, and it’s led by the leader (Kim Jong-un) who is arrogant. I consider North Korea a rogue nation discredited by the entire world,” Harris said, pointing out that Pyongyang has expressed its “willingness to use military provocations to achieve its national goals.”

In a saber-rattling move against South Korea and the U.S., the North has continued to build up its asymmetric capabilities and launch provocative actions. Last month alone, the North carried out live-fire drills twice near the Northern Limit Line, the de facto inter-Korean maritime border in the Yellow Sea.

“So I have to tell you that the U.S. remains vigil in the face of North Korea’s continued provocations and steadfast in our alliance’s commitment to the ROK. It is no accident that the first country that I visited as the Pacific Command commander in the bilateral sense was Korea,” he added, referring to South Korea by its official name, the Republic of Korea.
