On Asia Trip, Trump Met by Protests Calling on U.S. to Open Diplomatic Relations with North Korea

President Donald Trump continued his five-nation tour of Asia, landing in Vietnam today for the Asia-Pacific Economic Cooperation summit. This comes as Trump said on Thursday that he wants Russia's help in getting North Korea to give up its nuclear weapons. In Korea, he attempted to visit the Demilitarized Zone, but his fleet of helicopters was turned back due to bad weather. We speak with Professor Bruce Cumings, who just returned from Seoul, South Korea, where Trump was met with protests. He is professor of history at the University of Chicago and the author of several books on Korea, including "Korea's Place in the Sun: A Modern History."
