ROK Military Massacres in Vietnam: Official Documentation and Testimonies

SUMMARY

Allegations have emerged since the 1990s from Vietnamese survivors and South Korean civil society concerning massacres committed by Republic of Korea (ROK) troops against civilians during the Vietnam War. These claims often cite specific incidents, with some supported by testimony from survivors and South Korean civil society organizations. While a 2014 People's Tribunal on War Crimes by South Korean Troops in Vietnam was organized by South Korean civil society groups to investigate these claims, official recognition and accountability from the South Korean government remain a central demand.

Conversely, an inquiry from the U.S. Military Assistance Command Vietnam (MACV) commander William Westmoreland to ROK Forces commander Chae Myung-shin concluded that reported casualties were caused by 'Viet Congs disguised in [ROK...' uniforms, a finding that contradicts survivor accounts. The presence of official ROK military archives or direct testimonies from former ROK soldiers corroborating the scale and nature of these alleged massacres remains a key area of investigation.

STRONGEST CASE FOR

The strongest case for ROK military massacres is built upon consistent testimonies from Vietnamese survivors and the investigations conducted by South Korean civil society groups. These efforts culminated in the People's Tribunal on War Crimes by South Korean Troops in the Vietnam War, which heard survivor accounts and aimed to establish a record of the alleged atrocities. The persistence of these claims, alongside calls for official recognition and reparations, suggests a significant body of evidence from the victim's perspective that necessitates further official inquiry and acknowledgment.

STRONGEST CASE AGAINST

The primary counter-argument against the widespread attribution of massacres to ROK troops stems from the official ROK military response at the time. When questioned by MACV commander William Westmoreland, then-commander of ROK Forces in Vietnam, Chae Myung-shin, attributed civilian casualties to 'Viet Congs disguised in [ROK...' uniforms. Furthermore, some accounts argue that ROK soldiers were highly disciplined and had lower rates of civilian casualties compared to other forces. Without direct, verifiable ROK military records or corroborating testimonies from former ROK soldiers admitting to these massacres, the claims remain contested by the official narrative of the time.
