South Korea’s main opposition party is likely to announce its antagonism to the deployment of the U.S. Terminal High Altitude Area Defense (THAAD) anti-missile system in the country, following the election of legislator Choo Mi-ae to the party’s top post. Choo won the Minjoo Party’s leadership battle Saturday, the Korea Times reports, replacing interim chairman Kim Jong-in, who had maintained a neutral stance on THAAD.
