As Trump Pressures South Korea, His Ambassador Feels the Heat William Gallo As U.S. president, Donald Trump is compiling a growing list of statements that have made many South Koreans uneasy. But as diplomatic tension increases between the United States and South Korea, it is Trump's ambassador to Seoul who is at the center of the storm. Ambassador Harry Harris, a retired Navy admiral, is tasked with trying to sustain U.S.-South Korea relations even while helping push Trump's demand that Seoul drastically increase how much it contributes toward the cost of the U.S. military presence on the peninsula. Perhaps predictably, it's been a bumpy ride. For a second consecutive year, negotiators failed to reach an agreement before the military cost-sharing deal expired on December 31. At one point during this year's negotiations, the U.S. side stormed out, accusing South Korea of being "unresponsive" to U.S. requests. The two sides haven't been able to resolve their differences during six rounds of talks. If they can't reach a deal soon, local Korean workers at U.S. military bases could be furloughed. .
