This paper explains how South Korea's democracy has controlled the military since 1993. It reveals why the overpowered military has not faded even after the eradication of Hanahoe and the consolidation of democracy in South Korea in its aftermath. The democratic control over the military is examined focusing on: (1) budget, personnel, organization; (2) the judicial system; (3) security and defense policy; (4) personnel affairs, roles, and responsibilities; and an explanation based on laws and institutions, the strategy of key actors, and historical conditions of military confrontation. Under South Korea's democracy, the military budget, personnel, and organization are only partially controlled, leaving military commanders with jurisdiction over the military's judicial system. This is a result of legal and institutional limitations, as well as resistance from the Ministry of National Defense (MND) and the military. In matters of security and defense policy, the president has taken the initiative to revitalize obsolete systems through political compromise with the military. The primary means for the president to control the military has been the personnel management of the MND and the military. The military is likely to pledge its allegiance to the regime instead of citizens because the former has control over personnel affairs, which has frequently led to unofficial private groups of military officers and their political interference. This case in South Korea shows that the way society controls the military sows the very seeds of risk and allows us to rethink the challenges in controlling the military in a democracy.
