SEOUL -- The tensions that are ratcheting up on the Korean Peninsula are traceable to South Korean President Moon Jae-in's advice to North Korean leader Kim Jong Un at a meeting two years ago that left Kim underprepared for a summit with U.S. President Donald Trump.
After blowing up a joint liaison office with Seoul on June 16, Pyongyang then directed profanity at the South Korean president. In a piece carried in the June 17 edition of the Rodong Sinmun, the mouthpiece of the ruling Workers' Party of Korea, Kim Yo Jong, the younger sister of Kim Jong Un and first vice department director of the WPK's Central Committee, was full of indignation toward Moon.
