Is Kim Jong Un's little sister Kim Yo Jong running North Korea?
That's what the Global Post's Geoffrey Cain wants to know as rumors swirl around the question of the Supreme Leader's health.
Kim has not made a public appearance since Sept. 3, when he attended a concert with his wife. Before that, he was seen walking with a limp.
Late last month, the state-run Korean Central News Agency said the enigmatic 31-year-old dictator had been suffering from "discomfort," but would not elaborate.
That has led to speculation that Kim's younger sister, Kim Yo Jong, may be managing North Korea's affairs in her brother's stead.
