South Korean President Yoon Suk-yeol’s declaration of martial law on December 3 has sparked national controversy and drawn criticism for reviving anti-communist rhetoric rooted in the country’s authoritarian past. Yoon justified the move as necessary to protect the nation from “pro-North Korea” and “anti-state forces,” though many observers see the rationale as baseless and politically motivated.

This rhetoric harks back to South Korea’s post-Korean War era, where anti-communism was used to legitimize authoritarian rule and suppress dissent. High-profile examples include the violent crackdown on pro-democracy protests during Chun Doo-hwan’s regime in the 1980s. Although the country transitioned to democracy in 1987, remnants of this discourse resurface during periods of intense political conflict.

Yoon’s rhetoric has revived these divisive narratives, targeting NGOs promoting peacebuilding with North Korea and cutting funding for inter-Korean reconciliation projects. Critics argue this undermines civil society and democratic progress, exacerbating political polarization. Analysts see Yoon’s actions as a political strategy to rally his conservative base amid declining popularity.

The legacy of anti-communism remains a significant fault line in South Korean politics, complicating democratic progress and inter-Korean relations. Overcoming these divisions is viewed as essential for protecting the democracy South Koreans have fought to build.
