Crisis in Seoul: Yoon Suk Yeol's Misjudgment on Martial Law Triggers Political Upheaval
A groundbreaking action by South Korea's president prompts concerns about the fragility of democracy during a time of political and security tensions.
South Korea, often hailed as a democratic stronghold in Asia, is currently facing one of its most serious crises. President Yoon Suk Yeol’s brief martial law declaration, citing threats from North Korea and so-called "anti-state elements," has led to an impeachment motion threatening to cut his presidency short, only two years into his term.
Announced on the night of December 3, the controversial decree involved military deployment, restricting civil liberties, and accusing the opposition-dominated parliament of subverting the nation’s democratic essence. By morning, the National Assembly had held an emergency session to nullify the decree, compelling Yoon to reverse his decision amid intense domestic and international pressure.
Leadership Fault Lines
This incident highlights not only weaknesses in President Yoon's leadership but also issues within South Korea's governance structure. Yoon, a former prosecutor known for clashing with opposition lawmakers, defended martial law as a necessary action against a worsening security environment. However, critics claim the decision was more about consolidating power amid falling approval ratings, now alarmingly low at nineteen percent.
With a strong majority, the Democratic Party quickly moved to impeach Yoon, labeling his martial law order "an egregious violation of constitutional principles." If successful, Yoon would become the second South Korean president impeached since the country’s shift to democracy in the 1980s, joining Park Geun-hye, whom he once prosecuted.
Democracy on the Line
Though South Korea has experienced political upheavals before, the current situation is particularly precarious. The last martial law declaration in the country was over forty years ago under military dictatorship. Yoon’s move has evoked comparisons to that era, fueling fears of democratic regression. Public reaction has been strong: mass protests, union strikes, and candlelight vigils similar to those that removed Park in 2017.
International reactions have also been telling. The United States, South Korea’s key ally, voiced “deep concern” and indefinitely postponed high-level defense talks planned for the week. Meanwhile, China and Japan issued cautious statements, mindful of the geopolitical impacts of instability in Seoul.
A Lesson to Learn
What can be learned from this episode? It highlights the fragility of democracies dependent on charismatic yet divisive leaders. Yoon’s rhetoric—citing external threats and demonizing domestic opposition—might have energized his base but distanced moderates, exacerbating the partisan divide.
Additionally, the crisis underscores how democratic systems, however robust, can be susceptible to the misuse of emergency powers. Yoon’s error, aggravated by insufficient evidence to support his actions, has endangered his political future and cast doubt over South Korea’s democratic institutions.
Future Prospects
As the Constitutional Court prepares to rule on the impeachment motion, the stakes are immense. South Korea’s reputation as a regional democratic exemplar is at risk. Whether Yoon’s actions are perceived as an anomaly or indicative of deeper systemic problems will depend on the response of the country’s institutions in the coming weeks.
This episode should serve as a cautionary lesson—not only for South Korea but for democracies worldwide dealing with political polarization and security challenges. As Alexis de Tocqueville noted, “The health of a democratic society may be measured by the quality of functions performed by private citizens.” In Seoul, as citizens rally to protect their freedoms, this measurement is undergoing an unprecedented test.
