The development of North Korea's nuclear weapons has worsened to the sixth nuclear test in 2017, and despite the sanctions of the international community including our government, we have not been able to offer clear solutions and alternatives, and the current measures are not enough in case of North Korea is using nuclear weapons. This study suggests how we should be prepared against the use of nuclear weapons under the premise that North Korea will never give up development of nuclear weapons under any circumstances. The first chapter outlines the current status of our preparedness if North Korea makes a nuclear attack. The second chapter analyzes and evaluates the power of nuclear weapons and North Korea's nuclear weapons threat. In the third chapter, we analyze North Korea nuclear attack and analyze the wartime emergency situation and civil defense posture. Finally, in order to implement the solutions presented in the text, we will identify priorities and summarize further developments.

Due to a more favorable climate in the recent relationship between U.S. and North Korea, North Korea nuclear issue is expected to enter the new phase of nuclear verification. From now on, our government should make preparation for taking the appropriate steps against the situation developed after the declaration by North Korea. Therefore, this paper is to identify the problems that may be occurred in the process of verifying and dismantling North Korea's nuclear program and to suggest the policy considerations that should be incorporated in establishing the action plan for verifying and dismantling her nuclear program, based on the analysis of experiences to verify and dismantle the WMDs in the former Soviet Union and in Iraq, respectively.

This study explores the potential for tritium production in North Korea's 5MWe graphite-moderated reactor, a facility primarily associated with nuclear weapons material production. While existing research on these reactors has largely centered on plutonium, our focus shifts to tritium, a crucial element in boosted fission bombs. Utilizing the MCNP6 code for simulations, the results estimate that North Korea can possibly produce approximately 7-12 g of tritium annually. This translates to the potential production of 1-3 boosted fission bombs each year. By incorporating tritium production into assessments of North Korea's nuclear capabilities, our methodology provides insights into the dynamics of the country's nuclear force, revealing a more diversified and complex composition than previously assumed. The findings significantly aid policymakers, regulatory bodies, and researchers in comprehending potential proliferation risks associated with graphite-moderated reactors and in developing strategies to address the nuclear threat emanating from North Korea.

North Korea had recently conducted the fourth nuclear test and ICBM tests, dared nuclear provocation targeting the Korea and the international community. It is determined based on experiments of nuclear and missile in progress in North Korea that the technical level of nuclear force reached the completion stage of standardization, lightweight, and variation. It is expected to become reality that North Korea executes the nuclear provocation targeting the Korea and the international community in the near future. Nuclear bomb is an absolute weapon that the logic of counterattack after allowing the first strike of the other party cannot be applied due to its tremendous destructive power. Therefore, as the opponent to North Korea that it decided to hold the nuclear, the exercise of anticipatory self-defense in order to guarantee a minimum of right to life is not a choice, but the only essential correspondence concept. At the moment that the North Korean nuclear provocation is expected in the near future, it shall be provided with competence to strike the origin region of provocation by forming a national consensus of preemptive strike enforcement. Also, in preparation for the fifth nuclear test of North Korea, which is anticipated, the national competence must be mobilize to be able to ensure the 'Nuclear Option' from the international community.

The international community recognizes North Korea's nuclear and missile provocation as a real threat. This is due to the analysis and evaluation that has developed nuclear electro magnetic pulse of domestic and overseas North Korea experts, intelligence agencies related to electro magnetic pulse. Electro magnetic pulse experts are concerned about North Korea's nuclear electro magnetic pulse in the following aspects. First, industrial, military, medical, and living facilities in modern society are constructed with electrical and electronic systems. So, All electrical and electronic appliances will become neutralization if North Korea's nuclear electro magnetic pulse was set off over the world(i.e. Korean Peninsula, United States etc). Second, North Korea will judge that possibility of criticism by the international community is low from the point of view of an attacker. Because nuclear electro magnetic pulse aim to destroy only the electronic equipment of the opposite nation and cause damage rather than taking life. Finally, nuclear electro magnetic pulse is more threatening than weapons like mass destruction because it does not need to hit targets accurately and can strike a wide area with nuclear weapon of the low technology levels. In this respect, we will analyze and evaluate nuclear and missile development and make a prospects about nuclear electro magnetic pulse developed by North Korea.

The point of Bush administraion’s foreign policy is to support the promotion and stability of Democracy in Iraq and counter terrorism and spread of WMD with his strong propulsive force caused by his reelection. In such an environment, there are his leadership, his team, himself, Kim Jung Il, and a new understanding of North Korea after September 11 as the effective factors of Bush administration’s policy toward Pyongyang. Bush administration’s foreign policy of North Korea also shows the process of North Korea’s nuclear weapon program and the future scenario of the Korean Peninsula with "the persistence of solving North Korea’s nuclear weapon program such as the method having done in Lybia", "the holding unconditional talks with Pyongyang, and "the continual concerns with human rights in North Korea." The purpose of Bush administration’s foreign policy of North Korea is to make North Korea do not support terrorism rather than remove the nuclear weapon in North Korea. The process of outlining South Korea’s policy toward North Korea must be considered for "national interest" with reasonable analyses not just hopes For this, South Korea must access systematically human rights of North Korea, prepare projects for a daring approach on North Korea, and strengthen South Korea’s defense ability toward North Korea with deep alliance with U.S and systematize the mutual understanding channel between U.S and South Korea. In conclusion, South Korea must try to get specific methods and practices about Bush administration’s foreign policy of North Korea with national wisdom

In the year 2018, South Korea faces a crucial decision with regard to reunification. Starting from inter-Korean and US-North summits held from April through June, A rough journey for North Korea's "Complete, verifiable and irreversible dismantlement" began. Although South Korea insists that North Korea's Nuclear 'CVID' is the only minimum condition in the process of peaceful reunification, North Korea and other countries who support North Korea, including China and Russia, will possibly claim that North Korea's Nuclear 'CVID' will minimize their political and military positions internationally. Despite representatives from each country agreeing to North Korea's denuclearization, it is inevitable that many challenges still need to be resolved during the process. From the perspective of the Chinese government, North Korea is not a country that stimulates international conflicts. Instead, China can utilize North Korea as their political and tactical leverage against the US in order to compete for hegemonic power in Asia. In order to reject the emerging supremacy of China and resolve uncertainties in the denuclearization agreement and implementation process, I suggest the necessity of 'Korea-Japan Security Cooperation' as a 'second alternative' to achieve the North Korea's Nuclear 'CVID'.

The balance of power in conventional forces between the two Koreas works in favor of the South Korea in the Korea peninsula. But, the balancing mechanism between the two Koreas in asymmetric forces like nuclear and missile forces works absolutely in favor of the North Korea. That's why it should be timely for the ROK military to review existing strategy and revise a new counter strategy against the threat posed by the North Korea's nuclear and missile forces. The ROK military is now developing 4D, KAMD, KILL Chain strategies as means to cope with the North Korea's nuclear and missile threats. Considering efforts and resources invested now, the strategies are expected to be in place in next five or more years. However, approaches to those strategies seem to be rather fragmentary and conceptual than comprehensive and pragmatic. The types of strategies against the North Korea's military threats need to be a deterrence in peace time and a fighting and winning in war time in the Korean theater. But, the most important element in the deterrence strategy is the credibility. This study concludes with an new strategic concept titled "ADAD(Assured Defense, Assured Destruction)" as an alternative to existing strategies to deal with the North Korea's nuclear and missile threats.

The North Korean regime, Kim Jungun's foreign policy is changed frequently. And their military policy has no gravity. North Korea has developed nuclear weapons and long range missile. Now they have Inter-Continental Ballistic Missile. These activities redound a great threat in Korean peninsula. There are a no possibilities to give up its nuclear weapons and missile development. For the peace in Korean peninsula, we should make North Korea to abandon its nuclear himself through effective sanctions. Now China should effort to control North Korea. To reduce the threat we should coordinate the strategic interests of China and US. This study is to predict the North Korea military activities to analyze "military policies."

This paper analyzes the contents and the effects of the UNSC 2270, and its implications to South Korea's defense strategy and navy. The UN Security Council passed strong sanctions against North Korea which punish North Korea's 4^th nuclear test. The sanctions compared to the previous ones require international society to take practical actions such as comprehensive trade bans as well as diplomatic isolation which will put significant pains on North Korea. Especially, these measures would greatly hamper economic development policy of Kim Joung-un regime. Because Kim Jung-un regime has inherent legitimacy problems which stems from the third family succession of the power, economic difficulties may play an important cause on the regime instability in the long term. In fact, the United States sees this possibility as an option to coerce North Korea in which North Korea choose denuclearization for its regime survival. Nevertheless, the prospects of the UN sanctions are not so optimistic. Considering North Korea's willingness for nuclear development and its level of nuclear technology, North Korea will try to play a gambit with the US and South Korea by exploiting its strategic advantages. North Korea's response will have three following strategies. First, it would actively pursue political and economic survival strategy by using China's support for the regime, strengthening its power grip in the name of countering US hostile policy, and enhancing peace propaganda. Second, North Korea will accelerate efforts to position its status as a nuclear de facto state. For this purpose, it could create nuclear crisis on the peninsula. Third, it would exploit local provocations as an exit strategy to get over the current situation. In order to counter North Korea's actions and punish North Korea's behavior strongly, South Korea needs following strategies and efforts. It should first make all the efforts to implement the UN sanctions. Strong and practical nuclear deterrence strategy and capability with the U.S. should be developed. Effective strategy and capabilities for the prevention and deterrence of North Korea's provocation should be prepared. For this purpose, North Korea's provocation strategy should be thoroughly reviewed. Active international cooperation is needed to punish and coerce North Korea's behavior. Finally, South Korea should prepare for the possible occurrence of North Korea's contingency and make use of the situation as an opportunity to achieve unification. All these strategies and efforts demand the more active roles and missions of South Korea's navy and thus, nullify North Korea's intention militarily.
