Trump Gone, But Tensions Still Loom in US-South Korea Alliance William Gallo SEOUL, SOUTH KOREA - After U.S. President Joe Biden took office last week, perhaps no world leader breathed a bigger public sigh of relief than South Korean President MoonJae-in. "America is back," Moon declared in a congratulatory message marking Biden's inauguration. The statement didn't directly mention outgoing President Donald Trump, but the intent was clear. .[1]@JoeBiden, congratulations on your inauguration. America is back. America's new beginning will make democracy even greater. Together with the Korean people, I stand by your journey toward 'America United'.

Much to Moon's relief, the military cost-sharing friction will likely subside under Biden, who recently[6]calledfor an end to "extorting" Seoul over the issue. But some analysts warn another major alliance disagreement could soon emerge over how to handle North Korea. Improving relations with North Korea is a legacy-defining issue for the left-leaning Moon, a former human rights activist whose parents fled the North as war-time refugees. But Moon, whose five-year presidential term ends next May, is running out of time to achieve inter-Korean peace. Although he has vowed a final push to renew talks, progress will be difficult without the support of Biden, who is consumed with the coronavirus pandemic that has killedmore than420,000 Americans and devastated the U.S. economy. Different approaches It's not just an issue of Biden being distracted. At times, Biden and Moon appear to have important differences about whether and how to engage North Korea at all. As vice president, Biden helped oversee former President Barack Obama's policy of "strategic patience," which attempted to gradually apply economic and military pressure until Pyongyang was ready to negotiate. During his presidential campaign, Biden repeatedly referred to North Korean leader Kim Jong Un as a "thug," "tyrant," and "dictator." Biden has suggested he wouldn't meet Kim without progress on North Korea's denuclearization. Although the Biden administration hasn't yet decided on a North Korea strategy, AntonyBlinken, who is set to become secretary of state, says the UnitedStateswould consider using both diplomacy and increased pressure to convince North Korea to return to negotiations.
