This paper analyzed the origins of North Korean nuclear policy through the concept of ''Nuclear potential strategy''. Previous studies have remained in the phenomenal analysis that in 1962 North Korea suddenly switched to strengthening its military force in order to respond to the changes in international situation. This paper sought to clarify that North Korea''s nuclear policy is not a fragmentary policy pursuing only nuclear weapons or nuclear energy, but a strategy for securing nuclear potential.
The strategy of securing the nuclear potential is based on the hypothesis that any country can strategically devote its nuclear policy to the military at any time. Countries pursuing nuclear development strategies will continue to pursue advanced nuclear technologies that can achieve both economic and military objectives.
The results of the analysis on North Korean nuclear policy are as follows. First, North Korea''s nuclear policy was promoted for economic and military dual purposes by analyzing the policies and development process of nuclear energy in 1950'' s. Nuclear policy in the 1950s was a policy of peaceful use of nuclear energy, and North Korea pursued nuclear policy as a socialist industrialized nation, that is, economic growth strategy. The second is the analysis result of the change of the international environment in the 1960s, the policy decision factors, the response strategy of Kim Il Sung, and the changes of nuclear policy. North Korea has been pursuing a strategy to combine peaceful use of nuclear energy and military use by 1966 and 1966. Then, in 1967, Nuclear Military Exclusivity to the full-scale. The decisive factors are the US-China Cold War system, the Northeast Asian regional system in which the Korea-US-Japan Triangular Military Alliance and the North Korea-China-the Soviet Union Triangular Military Alliances collide, the nuclear threat of the United States, Small conflicts, the emergence of Park Chung-hee''s military, and changes in international affairs, such as the Vietnam War and the nuclear development of China.
Third, it is the analysis result of the correlation between the translation line and the nuclear policy. The translation route was Kim Il Sung''s national strategy to secure ''deterrence of war''. In 1966, the "strengthening of the defense force" was a transition of nuclear policy in a practical sense. The ''Defense Construction'' route can be said to be the transfer of nuclear power to the military. In other words, the translating route was a secret military-only policy that was pursued by the secret police. The translational route was adopted internally and secretly in 1962. This period was promoted from 1962 to 1966 with the aim of ‘Economy Construction’ at the first stage. During that time, North Korea, with its ambition for the "nuclear energy revolution", focused on securing nuclear technology centered on the nuclear power industry.
The second - stage translation line has been in full swing since 1967 with the aim of constructing a national defense. ''Defense construction'' was a long-term nuclear development strategy based on nuclear policy. The approach was to replicate nuclear and missile technology and to secure nuclear deterrence. Fourth, the results of analysis of the contents of the continuation and change of nuclear policy in 1950 ~ 1960s. The translating route was a strategy of securing the nuclear potential that dreams of ''nuclear future'' and ''nuclear energy revolution'' at the same time. Nuclear Potential Strategy is a strategy to reinforce nuclear technology until it establishes a nuclear power system that is militarily meaningful in nuclear technology acquired through the peaceful use policy of nuclear energy. From 1957 to 1966, North Korea pursued the ''10-year plan for science development''.
As a result, it has acquired a rudimentary nuclear technology. The 10-year plan for science development is a science and technology development strategy implemented since 1957. It is noteworthy that at the end of the 10-year plan of science development, in 1966, North Korea formulated the translation line as a strategic route. This suggests that the ''10-year plan for science development'' was a policy to pursue ''Nuclear potential strategy''. On the other hand, it demonstrates that North Korea has made ''defense construction'' in earnest based on the achievements of nuclear science and technology accumulated over 10 years. Therefore, the strategy of securing the potential of nuclear weapons is an important keyword that clarifies the correlation between the translation route and the nuclear policy. The strategy for securing the nuclear potential was tied to the "Declaration of Completion of Nuclear Armed Forces" on November 29, 2017, 50 years after the ''Defense Construction'' in 1967. Although peaceful use of nuclear energy has been reserved for 50 years, ''defense construction'' has yielded a successful outcome of nuclear deterrence.
In interpreting the translational route in terms of securing the potential for nuclear weapons, the declaration of the completion of nuclear armed forces on November 29, 2017 achieved the "defense construction". At the same time, we have reached a condition where we can switch to a peaceful utilization strategy of nuclear energy, which is another part of our strategy to secure our nuclear potential. This means that North Korea''s nuclear policy will return to its peaceful use of nuclear energy in 50 years after its transition to a nuclear development strategy in 1967. Kim Il-sung has pursued a strategy to secure nuclear potential under weak conditions of nuclear technology and as a ''long-term idea for the future''. On the other hand, Kim Jung-eun is a qualitatively different condition that secures the deterrence of the US and the high level of nuclear technology. In addition, it is the stage of consolidation of the national strategy of 60 years or the realization phase.
Kim Jung Eun''s ''New Era Industrial Revolution'' is bound to translating routes. The ''New Era Industrial Revolution'' is an economic revolution strategy through nuclear energy. As North Korea expresses, it is ''the completion of the economic construction and nuclear armed construction transfer line''. The ''New Era Industrial Revolution'' declared by Kim Jong Eun is to open the era of commercialization of nuclear energy, the era of nuclear energy revolution that Kim Il Sung dreamed of in the 1950s. Kim Jong Eun''s "Economy and Nuclear Translation line" confirms that Kim Il-sung''s translational route was a strategic route for implementing the nuclear potential strategy. This is supported by the dual logic of the economy and defense, the realization of defense construction completed by building a nuclear power system, and the declaration of commercialization of nuclear energy.
