The North Korean government told Swedish officials earlier this month that it wanted to expel King, the official said, and the U.S. government and Pyongyang communicated afterward via the Swedes about how to facilitate the process. There was no immediate clarity about why the North Koreans had decided not to keep King in custody, but the official said that the Biden administration had made no concessions to win King’s release.
Apparently the North Koreans turned him over to the Swedes, who took him across the border into China and handed him over to the US. He'll probably be court-martialed, thrown in Leavenworth for awhile, and dishonorably discharged.
Imagine being so useless and annoying that even the North Koreans can't be bothered to keep you around, even for a negotiating ploy. He must have provided them absolutely no intelligence whatsoever. Maybe they decided he wasn't worth the hassle and resources, or they were trying to show a side of rationality after overplaying things with Otto Warmbier. Or both, or neither.
