"It's a political victory that our country has never seen before, nothing like this. I want to thank the American people for the extraordinary honor of being elected your 47th President and your 45th President," Trump said, declaring his "magnificent" victory in the election.
Trump's return to the White House would have significant ramifications for South Korea, particularly in the realms of foreign policy and regional security. Here are some key areas where his political comeback will impact South Korea.
Defense and security
During his presidency, Trump often called for South Korea to contribute more to the costs of U.S. military presence on the Korean Peninsula, which could be a point of contention again if he returns. Trump could push for renegotiations on defense spending and troop deployments, which could affect South Korea's defense strategy and military readiness.
During his first presidency in 2017, Trump demanded that Seoul pay $5 billion for the upkeep of U.S. Forces Korea (USFK) on the Korean Peninsula, five times the amount Seoul was paying at the time.
Despite the current agreement having nearly two years left until its expiry, similar concerns led the two countries to expedite negotiations and sign a defense cost-sharing deal, known as the Special Measures Agreement (SMA) on Monday, just a day before the U.S. presidential election.
Nevertheless, Trump could still attempt to break the deal and demand a renegotiation, possibly pushing for an astronomical hike for the upkeep.
South Korea has "a money machine. We protect them (South Korea) from North Korea and other people. North Korea is very nuclear, I got along with him (North Korean leader Kim Jong-un) very well," he said in his recent remarks, claiming that South Korea does not pay "anything." He also argued that he made South Korea agree to raise the costs, but "Biden then cut it back, and it's a shame."
Relations with North Korea
Trump's engagement with North Korea marked a significant departure from traditional American diplomatic approaches, culminating in photo ops with Kim at their first summit in Singapore in 2018. However, inter-Korean relations soon became strained when their follow-up summit in Hanoi the following year ended in failure.
But Trump's return again raises expectations for improved relations with North Korea, as he could push to restart direct talks with Kim, potentially providing opportunities for South Korea to engage in dialogue and make progress in inter-Korean relations amid a prolonged stalemate. Yet challenges remain, as his approach remains erratic and unpredictable.
Seoul would need to carefully balance its own engagement with North Korea and its security interests, especially if Trump resorts to his signature "America First" approach or resumes harsh rhetoric toward Pyongyang.
Due to Trump's inconsistency and unpredictability in his political stances and policies, South Korea would face various challenges in inter-Korean relations. Trump once boasted that his "love letters" with Kim avoided conflict with North Korea. "I got along with him, and we stopped the missile launches from North Korea. Now, North Korea is acting up again, but when we get back, I get along with him," he said during his campaign trail in July. "He'd like to see me back too. I think he misses me..... It's nice to get along with somebody who has a lot of nuclear weapons."
When Harris vowed not to "cozy up to" tyrants and dictators like Kim, Trump countered that "getting along" with him is a "good thing," suggesting that he would engage with North Korea if reelected.
Trump's "America First" approach could also impact multilateral diplomacy, potentially reducing American engagement in global affairs. He has consistently criticized multilateral commitments, saying, "We have long been taken advantage of by other countries. And think of it. Oftentimes, these other countries are considered so-called allies."
For this reason, South Korea would have difficulties coordinating with the international community and gaining multilateral backing without U.S. support in maintaining regional peace and stability. This would be critical, especially given the deepening military ties between North Korea and Russia, which led to Pyongyang's recent troop deployment to Moscow to support its war in Ukraine.
With potential shifts in U.S. foreign policy priorities, South Korea's efforts toward North Korea's denuclearization could also falter, requiring Seoul to come up with new diplomatic strategies amid the potential weakening of collective global coordination.
Under the previous Trump administration, the U.S. withdrew from several international agreements, such as the Paris Climate Agreement, the Trans-Pacific Partnership, and UNESCO, although he may engage in selective, cost-effective alliances, as long as they align with U.S. interests.
Trump's return presents both opportunities and challenges. South Korea will need to thoroughly prepare for potential shifts in key policies including political and economic agendas, while maintaining its strong alliance with the U.S.
Meanwhile, South Korean President Yoon Suk Yeol sent a congratulatory message to the U.S. president-elect, who is poised to begin a second term and will become the first since Grover Cleveland in 1892 to return to the White House for a non-consecutive term.
"Under your strong leadership, the future of [South Korea]-U.S. alliance and America will shine brighter. Look forward to working closely with you," Yoon wrote on X.
