Talks between the United States and North Korea are on hold once again. North Korea has been launching ballistic missiles. And officials are warning the U.S. government to “change” its way of negotiating by the end of the year. In the United States, President Donald Trump continues to praise his relationship with North Korean leader Kim Jong Un. But a leading candidate seeking to replace Trump as president is threatening to take action against Kim if elected. The government of South Korean President Moon Jae-in helped bring about the U.S.-North Korea nuclear talks in 2018. But Moon now finds he can do little to move the negotiations forward.
