Kim Yo Jong, the North Korean leader’s famous sister, appeared to fall from grace when she was abruptly demoted from the country’s powerful Political Bureau over the weekend. But only a few days later, she hurled insults at Seoul in scathing state media remarks, calling South Koreans “top-class idiots” and leading some experts to believe that she’s actually emerging as an up-and-coming figure.

On Wednesday, Kim reportedly complained about how the South Korean military said it was “closely monitoring” a potential North Korean military parade. In her view, it’s none of Seoul’s business: “South Koreans are truly a bunch of weirdos” with “nothing better to do” than watch the DPRK, she said.
