North Korean leader Kim Jong Un deployed a new weapon at the Olympics to fight back against the Trump administration’s sanctions and threats of a preemptive strike against his nuclear program: His sister.
Kim Yo Jong shook hands with South Korean President Moon Jae-in, cheered enthusiastically for a unified Korean team, and displayed a sense of humor in weekend meetings. She also delivered a letter inviting Moon to a summit with her brother in Pyongyang, and asked him to play a “leading role” in reuniting the two Koreas after nearly seven decades.
