Things don't seem so great in the U.S.-North Korea dynamic — which puts South Korea in a bind. With Pyongyang ominously hinting it might scrap next month's much-anticipated summit between North Korean leader Kim Jong Un and U.S. President Donald Trump, South Korean President Moon Jae In's second visit to the United States has shifted its focus from last-minute summit coordination to something more like damage control. But Seoul has been here before — more than once. From Crisis to Hope When Moon first visited the United States last June, he was facing two issues that looked as if they were about to get out of hand. The Trump administration was threatening to re-evaluate the U.S. trade relationship with South Korea as part of its "make in America" push.
