Kang Yeonsak

Born in North Korea, Kang's father was executed when he was young. His mother and him eventually were able to defect to the South but at the cost of her life, as she was killed by an American landmine. Kang settles into South Korea entering the government as an assistant to the South Korean Prime Minister. When arriving at the White House, Yeonsak seemed pleasant and kind but has a master plan. His plan unfolded when North Koreans bombed the White House and suicide bombers destroyed the front gates. He holds the President and some other politicians hostage and slowly kills each one in an attempt to get access to Cerberus, nuclear weapons that will destroy the United States into a nuclear wasteland. At the same time, Mike Banning, a former US Army Ranger is trying to get to Yeonsak and the President. Yeonsak eventually kills the Vice President on camera and tries to escape the White House. Outside the White House, he attempts to kill the Secretary of Defense but Banning intervenes and saves her life. After shooting the President and wounding him, Yeonsak fights Banning one on one but is eventually stabbed in the head, killing him.
