South Korea's police launched an investigation on Thursday into whether Pres. Yoon Suk Yeol committed treason and insurrection following two complaints over his short-lived martial law declaration this week.
The probe extends to other top officials, including army chief of staff Gen. Park An-su, Interior Minister Lee Sang-min,and the resigning Defense Minister Kim Yong-hyun. According to Yonhap, a travel ban has been issued on the latter.
Yoon clearly violated constitutional and legal requirements with acts that amount to insurrection and treason, such as deploying special forces to occupy the National Assembly and arrest opposition leaders. He failed to point to any constitutionally approved grounds for martial law, bypassed cabinet review, and failed to notify to the National Assembly, undermining democratic checks and balances in South Korea.
While Pres. Yoon’s martial law declaration was a grave mistake, the deeper issue lies in South Korea’s polarized politics. The clash between an overpowered opposition and a fragile presidency reflects systemic flaws, including outdated electoral rules and power centralization. Without reform, such divisions will continue to destabilize the nation, regardless of who is in office.
