When South Korea’s ousted President Yoon Suk Yeol stepped into the courtroom, the case against him had already taken on a distinct shape: not just power misused, but a chain of decisions meant to manufacture a crisis.
On Friday, the Seoul Central District Court sentenced Yoon to 30 years in prison in a case alleging he ordered drone flights over Pyongyang in 2024. The court said the purpose was to heighten tensions with North Korea and, in turn, justify Yoon’s martial law move at home.
The judges found Yoon and his former defense minister. Kim Yong Hyun. guilty of aiding an adversary and abusing their power. In the court’s account. they sought to provoke North Korea into launching armed attacks or other serious provocations against South Korea in order to “manufacture a national emergency.” The court added that their actions harmed South Korea’s military interests by exposing its capabilities. undermining its ability to conduct future operations. and prompting North Korea to strengthen its defense posture.
This wasn’t the first severe sentence tied to Yoon’s December 2024 attempt to seize control. The same court had earlier sentenced Yoon to life in prison for a rebellion conviction over his short-lived imposition of martial law in December 2024.
The drone case began with allegations from North Korea. Pyongyang accused Seoul of flying drones over Pyongyang to drop propaganda leaflets three times in October 2024. Kim Yong Hyun, then South Korea’s defense minister, issued a vague denial. After that, the Defense Ministry said it could neither confirm nor deny the allegations.
Tensions rose sharply after the accusations, but they did not lead to any military clashes.
Yoon’s legal team rejected the government’s framing. In arguing for a different interpretation. they said the drone flights were a response to North Korea flying thousands of trash-carrying balloons into South Korea earlier in 2024. They said a guilty verdict would undermine South Korea’s security interests. They did not immediately say whether they would appeal the 30-year sentence.
Behind the courtroom timeline sits a more combustible story about intent—one prosecutors described as both strategic and political.
Investigators led by special prosecutor Cho Eun-suk had sought a 30-year prison term for Yoon. They accused him of trying to create a warlike situation between the Koreas while plotting an authoritarian push to remove political opponents and “monopolize” power. For Kim Yong Hyun, prosecutors asked for a 25-year sentence. Kim was described as a key confidant of Yoon who helped plan and mobilize forces for Yoon’s martial law declaration.
That martial law episode is the broader backdrop the court linked to the drone allegations.
Yoon proceeded with the declaration late in the night of Dec. 3, 2024. In a televised address, he accused liberal lawmakers of being “anti-state” forces, portraying them as North Korea-sympathizing. He cited multiple grievances, but emphasized opposition impeachments of senior officials and cuts to his government’s budget bill.
Martial law lasted about six hours. Lawmakers broke through a blockade of soldiers and police at the National Assembly and voted to overturn it. forcing Yoon’s Cabinet to lift the measure. Within days, Yoon was suspended from office, impeached, and formally removed by the Constitutional Court. He was later arrested in July 2025, and several criminal trials are ongoing.
The most serious case—rebellion—has become its own long-running battle. The verdict has been appealed both by Yoon and prosecutors, who had sought a death sentence.
Now, with the drone ruling added on top of the earlier life sentence, the timeline in the court’s view sharpens into a single narrative: actions taken abroad to pressurize North Korea, and decisions inside South Korea to justify extraordinary power at home.
In the narrow window between October 2024 drone allegations and the December 2024 martial law push. the court said South Korea’s security posture was compromised—its capabilities exposed. its future operations disrupted. and North Korea’s defensive readiness strengthened. For Yoon’s lawyers. the opposite is true: the drones were retaliation for North Korea’s trash-carrying balloon campaign. not the opening move of a manufactured emergency.
For now, Yoon remains caught between two legal tracks—one already severe and one still contested—while South Koreans watch whether appeals will turn Friday’s ruling into a final chapter or another step in a prolonged fight over accountability and national security.
