South Korean president faces setback in elections

South Korean president faces setback in elections

Yoon Suk-yeol's foreign policy agenda is likely on ice as the opposition party wins control of parliament

Analysis | QiOSK

Today, South Korea held its quadrennial parliamentary election, which ended in the opposition liberal party’s landslide victory. The liberal camp, combining the main opposition liberal party and its two sister parties, won enough seats (180 or more) to unilaterally fast-track bills and end filibusters. The ruling conservative party’s defeat comes as no surprise since many South Koreans entered the election highly dissatisfied with the Yoon Suk-yeol administration and determined to keep the government in check.

What does this mean for South Korea’s foreign policy for the remaining three years of the Yoon administration? Traditionally, parliamentary elections have tended to have little effect on the incumbent government’s foreign policy. However, today’s election may create legitimate domestic constraints on the Yoon administration’s foreign policy primarily by shrinking Yoon’s political capital and legitimacy to implement his foreign policy agenda.

For example, in pursuing a trilateral security partnership with the United States and Japan to deter North Korea and counterbalance China, Yoon has had to endure strong public backlash against his decision to accommodate Japan’s position on the issue of compensating Korean victims of Japanese forced labor during World War II. The Yoon administration’s indirect provision of munitions to Ukraine against Russia and its critical stance on China regarding the Taiwan issue have also seemingly been at odds with public sentiments — with polls reflecting that many South Koreans are worried about being too involved in Taiwan and Ukraine issues.

There are bolder steps Yoon might take in advancing his so-called “value-based” foreign policy agenda, like directly arming Ukraine against Russia; further aligning with the United States against China, such as by endorsing U.S. semiconductor restrictions against China and pursuing closer ties with Taiwan; and upgrading military ties and coordination with Japan. Again, such initiatives would defy domestic opposition to increasing tensions with China and Russia, reject calls to maintain stable economic ties with China, and ignore public wariness about moving too fast in normalizing military relations with Japan without addressing the thorny historical issues.

A ruling party victory would have provided Yoon with the political capital he needs to pursue his foreign policy agenda. But its massive defeat will likely put Yoon on course to become a lame duck. Keeping Yoon as the party's face could also lead to another failure in the 2027 presidential election, so the ruling party will be inclined to keep him at a distance and tread more carefully about aligning Yoon with controversial issues. This could mean that the ruling party may abandon Yoon on some of his more controversial foreign policy initiatives. Whereas Yoon may now want to prioritize his foreign policy agenda, the ruling party may want to emphasize pragmatism that appeals more to the large coalition of non-partisan voter base in South Korea.

The opposition liberal party will also have greater legislative freedom to unilaterally pass politically contentious bills, such as a bill ordering a special investigation into the first lady’s corruption scandal, that Yoon would likely veto. Repeated direct interventions in the legislative process will likely consume a good deal of Yoon’s political capital that could otherwise be used to advance his foreign policy initiatives.

The election result may not necessarily mean Yoon’s foreign policy initiatives face an imminent threat of deadlock or reversal. He appears to have a strong personal commitment to his “value-based” foreign policy and has expressed a firm willingness to pursue his agenda regardless of domestic pressure. Nevertheless, with shrunken political capital and legitimacy, it seems clear that he is now in a more difficult place to exercise the kind of personal influence he has had on South Korea’s foreign policy thus far.

Middle East

The blitzkrieg offensive which ousted Syrian dictator Bashar al-Assad in December 2024 has sparked an explosive political and military reaction across the country.

Al-Qaeda offshoot Hayat Tahrir al-Sham (HTS) seized Damascus, Israel extended its occupation in southern Syria, and Turkey launched fresh military operations targeting the secular, multi-ethnic, Kurdish-led federation in North and East Syria (NES), where the U.S. has long maintained a military presence with boots on the ground, justified by its anti-ISIS mission.

Ukraine and Europe can't afford to refuse Trump's peace plan

Europe

Most of the peace plan for Ukraine now sketched out by the Trump administration is not new, is based on common sense, and has indeed already been tacitly accepted by Kyiv.

Ukrainian officials have acknowledged that its army has no chance in the foreseeable future of reconquering the territories now occupied by Russia. Vice President J.D. Vance’s statement that the U.S. plan would “freeze the territorial lines…close to where they are today” simply acknowledges an obvious fact.

Could a Blobby enclave be sowing chaos at DoD?

UPDATE 4/24, 5:15 PM: The Defense Policy Board website has been scrubbed, as reported by The Intercept. The list of DPB members can still be viewed on an archived version of the website.


Discussing alleged Pentagon leaks with Tucker Carlson on Monday, recently ousted DoD official and Iraq war veteran Dan Caldwell charged that there are a number of career staff in the Pentagon who oppose the current administration’s policies. He then took particular aim at the the Defense Policy Board as a potential source of ongoing leaks to the press.
