Philippine President Rodrigo Duterte said on Sunday North Korean leader Kim Jong Un, whom he had previously called a “fool”, is now the “hero of everybody”. Duterte has more than once criticized Kim over his nuclear ambitions. Last year he questioned his sanity and urged the United States to show restraint and not be baited by a man who “wants to end the world”. The leaders of North and South Korea agreed on a common goal of a “nuclear free” peninsula during a summit on Friday. Meeting at the Demilitarized Zone that has divided the Koreas for more than six decades, Kim and Moon announced they would work with the United States and China this year to declare an official end to the 1950s Korean War.
