North Korean leader Kim Jong Un has vowed to implement the toughest anti-U.S. policy, just weeks before Donald Trump takes office as U.S. president. Experts believe that a quick resumption of Kim-Trump summitry is unlikely as Trump would first focus on conflicts in Ukraine and the Middle East. Kim called the U.S. 'the most reactionary state' and criticized the U.S.-South Korea-Japan security partnership. He set forth tasks to bolster military capability and improve the mental toughness of North Korean soldiers. Efforts to get North Korea to rid itself of nuclear weapons are further complicated by its deepening military cooperation with Russia.
