Many have seen the establishment of civilian and democratic control over the military as a necessary, although not sufficient, condition for the consolidation of a nascent democracy. The establishment of civilian and democratic control over the military in South Korea was a long and, some would argue, uncompleted process. A coup in 1961 led by Park Chung-hee, a major-general, led to the establishment of an authoritarian regime that, while going civilian, was based on the control of the military and the intelligence services. Park was assassinated by the head of the Korean Central Intelligence Agency in October 1979; however, the hopes of moving in the direction of democracy were soon squashed when Chun Doo-hwan, and his comrades in arms from the secret Hanahoe (One Mind) club of Korean Military Academy graduates, first took power over the military through an internal coup, and then took control over the government. Under significant internal, and external, pressure Chun Doo-hwan agreed to step down from the presidency in 1987 and allow the writing of a new constitution that led to free elections to the presidency in December 1987. The opposition lost the 1987 election due to its inability to agree upon a united candidate. The winner was Roh Tae-woo, a participant in the 1979–1990 coup, who would during his presidency take important steps when it came to establishing civilian control over the military. However, it was first with the inauguration of the Kim Young-sam in 1993 that the establishment of firm civilian control was achieved. He engaged in a significant reorganization of, and moved against the power of the secret societies within, the army. He also promoted the idea of a politically neutral military. This most likely played a significant role when Kim Dae-jung, the first opposition candidate, won the presidency in December 1997, as the military remained neutral and accepted the outcome of the electoral process. There has since been a strengthening of civilian control over the military in South Korea. However, there are a number of important issues that need to be dealt with in order to ensure full democratic control over the military and the intelligence services. While the military, as an institution, has stayed neutral in politics, military and intelligence resources have been used in attempts at influencing public opinion in the lead-up to elections. In addition, comprehensive oversight by the legislature continues to be weak and the National Security Law remains on the books.
