South Korean President Lee Jae-myung has long pushed for stronger homegrown defences. However, US President Donald Trump's decision to cut joint military exercises has sparked alarm in some quarters in Seoul. This was reported by Qazaqyia.kz citing The Guardian.
At their first summit in the Oval Office in August last year, Lee Jae-myung told Trump: "If you, Mr President, become the peacemaker, then I will assist you as the pacemaker." The remark captured the thrust of Lee's approach to the North: dial down the military posturing and make repeated peace overtures to revive dialogue, even if they have been consistently rejected by Pyongyang largely over Seoul's insistence on denuclearisation.
Fast forward to this week, and Trump's move to cut joint military exercises with South Korea echoes what Lee had pledged to achieve during his term in office, as a possible tool for reviving dialogue with Pyongyang. Lee's broader message is that South Korea should take more responsibility for its own defence and reduce its reliance on others. On Tuesday, he used the moment to renew calls for wartime operational control of the military and progress on his country's nuclear submarine programme.
Trump has delivered on the drills, albeit in the blunt, discourteous fashion typical of the president: via social media, hours before the drills were to begin. Yet the move has inverted South Korea's usual political lines, where the left-right divide is shaped more by attitudes toward North Korea – hawks versus doves, confrontation versus engagement – than by economic or social values.
Reducing joint drills has long been advocated by some on the Korean left. A rightwing US president imposing the policy on his centre-left South Korean counterpart lands awkwardly for both sides. While some see the reduction as potentially useful for diplomacy, the louder concern in Seoul is that Trump is weakening a key pillar of deterrence – and leaving South Korea with little say over decisions that directly affect its security. That may strain an alliance that has been the bedrock of security on the peninsula since the Korean war.
The opposition conservative People Power party has called the decision a "security disaster" and warned of a return to "Korea passing", a term used when Seoul feels sidelined in matters directly affecting it. Conservative newspapers have been almost unanimous in calling the cut reckless. The influential Chosun Ilbo has gone further, blaming Lee's government directly for inviting it.
The left has not shared that sense of alarm. Hankyoreh, one of the country's main progressive papers, raised no objection to the substance of Trump's decision, only to how it was delivered: unilaterally and disrespectfully on social media, calling it "regrettable". Kyunghyang Shinmun took a more positive view, saying the cut could help create an atmosphere for dialogue with North Korea, so long as deterrence held.
Reducing tensions with North Korea and creating space for dialogue are central to Lee's agenda. The ruling party has been quiet on the move, but openly welcoming Trump's decision could put it at odds with a base that has generally viewed Trump with suspicion, if not hostility.
Aside from the domestic politics, the episode is likely to deepen doubts about Washington's commitment to its allies, doubts that have been building for years since Trump's first term, said Prof Jaechun Kim, who teaches international relations at Sogang University in Seoul. Trust, he argued, was the foundation of any alliance, and remarks like Trump's reinforce the impression that America's obligations are increasingly viewed "through a highly transactional lens", one that could shape how South Koreans judge US reliability long after Trump has left office.
Then there is the issue of the nuclear deterrent. South Korea enjoys protection under the US nuclear umbrella, but public support for an independent deterrent among South Koreans and their neighbours has hovered around or over 70% in recent surveys. The latest news may push that support higher still.
Prof Kim expects Pyongyang to welcome any sign of friction within the alliance but doubts that it views improving relations with Washington as a priority, given the stronger backing it now enjoys from both China and Russia compared with during Trump's first term. "The irony," he said, "is that [US] policies intended to reduce American burdens may ultimately strengthen calls for independent nuclear deterrents among US allies".
