Around the world, our allies are worried. Here in South Korea, President-elect Donald Trump’s unexpected election victory has fueled a deep sense of uncertainty about the future of American leadership in Asia and the world. Government officials and foreign policy experts are scrutinizing every Trump utterance about South Korea, trade and security made during the campaign, and they don’t like what they find. As I have been asked repeatedly during my stay here, does he really believe that the U.S.-Korea Free Trade Agreement kills American jobs, that South Korea does not contribute substantially to the costs of basing our soldiers here, or that South Korea and Japan should defend themselves against the “maniac of North Korea,” including by acquiring their own nuclear weapons?
