Statement on the Research Center for Nuclear Weapons Abolition, Nagasaki University (RECNA) Welcomes German Foreign Minister’s Visit to Nagasaki

Research Center for the Nuclear Weapons Abolition, Nagasaki University (RECNA)
July 8, 2022

H.E. Ms. Annalena Baerbock, Federal Minister for Foreign Affairs of Germany, will visit Nagasaki on July 10, the Prefecture and the City of Nagasaki announced. The visit precedes her meeting with Foreign Minister Yoshimasa Hayashi in Tokyo. In Nagasaki, her visit to the Nagasaki Atomic Bomb Museum, offering flowers at the Nagasaki National Peace Memorial Hall for the Atomic Bomb Victims, and meeting with a hibakusha, an Atomic Bomb survivor, have been scheduled. As the crisis in Ukraine raises concerns about the use of nuclear weapons, it has become increasingly important to focus attention on such weapons’ inhumanity. As an academic center in the A-bombed city, RECNA sincerely welcomes her visit.

Germany attended the First Meeting of States Parties to the Treaty on the Prohibition of Nuclear Weapons (TPNW), held in Vienna from June 21 to June 23, as an observer country. Together with the Netherlands, Norway, and Belgium, Germany was one of the few member states of the North Atlantic Treaty Organization (NATO), which is a self-declared “nuclear alliance,” to participate the meeting as an observer.

In his statement issued at the meeting1, the German ambassador noted the importance of the “humanitarian perspective” and reiterated his country’s commitment to “engaging in constructive dialogue and exploring opportunities for practical cooperation.” He also stressed that “broader attention and engagement” should be given to the issue of “victim assistance and environmental remediation” stipulated in Articles 6 and 7 of the TPNW. As the “Vienna Action Plan” adopted by the States Parties of the TPNW calls for greater dialogue and cooperation with states outside of the treaty, Germany’s positive stance gives hope for new developments in the future. We hope that Germany will be a leader in drawing the nuclear armed states and countries under the nuclear umbrella, including Japan, to “constructive dialogue.”

Germany, together with Japan, as core states of the “Non-Proliferation and Disarmament Initiative (NPDI)” and the “Stockholm Initiative for Nuclear Disarmament,” have an important role to play in determining the success of the NPT Review Conference to be held from August 1 to August 26. We look forward to further initiatives and actions by Germany to advance nuclear disarmament. Next year, Japan takes over the G7 Presidency and the summit will be held in Hiroshima. We hope that Germany, which holds this year’s Presidency, will strengthen its cooperation with Japan so that the G7 Heads of State and Government can demonstrate their strong will to realize a “world without nuclear weapons” at the Hiroshima summit. As part of this effort, we strongly request that the Meeting of the G7 Foreign Ministers be held in Nagasaki as an opportunity to further expand awareness of the inhumanity of nuclear weapons.

Statement on the “Japan-U.S.” and “ROK-U.S.” Joint Leaders’ Statements:
From the Perspectives of Denuclearization of Northeast Asia and Nuclear Disarmament

Research Center for the Nuclear Weapons Abolition, Nagasaki University (RECNA)
May 25, 2022

The Republic of Korea (ROK)-United States Joint Statement1 and the Japan-U.S. Joint Statement2 were issued on May 21 and 23, 2022, respectively. They were both comprehensive statements covering a wide range of topics, including not only security and alliance relations, most notably related to the Ukraine crisis, but also economic security, climate change, and pandemics. The following are RECNA’s views on some of the most noteworthy points of these statements from the perspective of the denuclearization and security of Northeast Asia, as well as nuclear disarmament and non-proliferation.

1. Denuclearization of the Korean Peninsula: Needs for confidence-building and a new security framework for the entire region

Both the ROK-U.S. and Japan-U.S. Joint Statements confirmed their commitments to the “denuclearization of the Korean Peninsula.” How to move it forward will be even more important from now on, and RECNA believes that it is essential to strengthen diplomacy toward stability and peace on the Korean Peninsula, carrying on the spirit of the U.S.-Democratic Republic of Korea (DPRK) Joint Statement issued at the Singapore Summit3. To this end, it is necessary to continue efforts for confidence-building and dialogue throughout Northeast Asia, including with China and Russia, and to propose a new security framework. Establishing a framework for disarmament and arms control is also indispensable, because security and disarmament/arms control are deemed to be paired and inextricably linked. In addition, diplomatic efforts should be made to ease tensions beyond “confrontation,” including humanitarian assistance to the DPRK, which is now facing a pandemic crisis. The DPRK should acknowledge that its very best policy is to exercise restraint in its nuclear and missile tests and embark on the path of dialogue.

The joint statements included strengthening extended deterrence and response capabilities to respond to the threats posed by the DPRK, China, and Russia, but, contrary to the intention, placing too much emphasis on this direction is fraught with the risk of further increasing tensions in the region. Thus, we demand the relevant countries constantly recognize the need for communication and dialogue at the leadership level, as indicated by the joint statements, and reconsider diplomatic strategy for averting a crisis.

2. Nuclear disarmament and non-proliferation: Strengthening the norm of “non-use of nuclear weapons

Although not included in the ROK-U.S. Joint Statement, the Japan-U.S. Joint Statement is commendable in that it confirms the intent toward a “world without nuclear weapons” and clearly states the strengthening of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the increase of transparency, and nuclear risk reduction, the latter of which has been recognized as more of a reality due to the Ukrainian crisis. However, compliance with NPT Article VI was not included. In preparation for the NPT Review Conference to be held in August this year, we would like to reiterate our appeal to the nuclear weapon states to strengthen the norm of “non-use of nuclear weapons” in accordance with the joint statement of the leaders of the five nuclear weapon states released on January 3, 20224, which affirmed that “a nuclear war must never be fought.”

3. Holding the G7 Summit in Hiroshima: Starting a new trend of nuclear disarmament from the A-bombed city

As an academic body in an A-bombed city, we greatly welcome the announcement at the joint press conference5 that the decision had been made that the G7 summit would be held in Hiroshima in 2023. This will be an excellent opportunity to stem the tide of the nuclear arms race and create a new trend toward nuclear disarmament. From the A-bombed city of Hiroshima, it is hoped that the leaders of the G7 nations will make appeals to the world about the “inhumanity” of nuclear weapons and the reality of the atomic bombings, and show their renewed determination toward a “world without nuclear weapons.”

Policy Proposal for Support to Radiation Victims in accordance with the Treaty on the Prohibition of Nuclear Weapons  [JPN]

Policy Proposal 2022.4

Introduction

Nagasaki University and humanitarian disarmament

 The Treaty on the Prohibition of Nuclear Weapons (TPNW) legally entered into force in January 2021. In contrast to traditional arms control treaties that merely reduce or prohibit the use of weapons to address national security concerns, the TPNW views these issues from a humanitarian perspective. As such, its ultimate goals are to achieve a total ban of nuclear weapons as inhumane weapons, and to provide support to people who have been exposed to radiation through the use and/or development of those weapons. With these aims, the TPNW is rooted in the concept known as humanitarian disarmament.

 However, we are still far from attaining a world in which all nuclear weapons are outlawed, as countries possessing these weapons, as well as their allies, seem to have turned their backs on the TPNW. Meanwhile, health hazards and anxieties persist due to radiation exposure,including that which occurs from nuclear testing and radioactive fallout. These unabated problems require urgent support from the humanitarian perspective. To demonstrate concrete effectiveness in the early stages of a humanitarian disarmament treaty such as the TPNW, it is essential to devise a system that can provide both physical and psychological support to individuals with radiation exposure, regardless of whether any harmful effects are currently apparent.

 Our institution, under the new educational system introduced through the National School Establishment Law in 1949, employs its educational philosophies and research abilities to actively work toward the creation of a world in which there is unity and peace. This was precipitated by the enormous damage wrought by the atomic bombing of Nagasaki in August 1945. A survey conducted by the A-bomb Material Preservation Committee of Nagasaki showed a devastating human toll, with 73,884 casualties and 74,909 wounded (as of December 1945)¹. Among these victims were nearly 1,000 students and faculty members from the Nagasaki Medical College (the predecessor to Nagasaki University, which included both the Specialized School of Medicine and the Specialized School of Pharmaceutics), Nagasaki Normal School, and Nagasaki Higher Commercial School². In view of this historical background of our institution and the central purpose of humanitarian disarmament framed by the TPNW, the Atomic Bomb Disease Institute at Nagasaki University and the Research Center for Nuclear Weapons Abolition, Nagasaki University jointly drafted a proposal to support radiation victims, especially those who have potentially incurred damage from radiation exposure following nuclear testing.

 It would be greatly appreciated if this proposal provided practical reference and was developed to make a significant contribution to advancing the cause of supporting radiation victims at the first Meeting of States Parties to the TPNW, scheduled to take place in Vienna in 2022.

Research Center for Nuclear Weapons Abolition, Nagasaki University (RECNA) issued Statement on the Russian Invasion of Ukraine and Nuclear Risk on February 25, 2022.


 

Statement on the Russian Invasion of Ukraine and Nuclear Risk

Research Center for the Nuclear Weapons Abolition, Nagasaki University (RECNA)
February 25, 2022

On February 21, 2022, Russia recognized the independence declarations of the pro-Russian separatists-controlled areas in eastern Ukraine, and on February 24, launched attacks on military facilities and major cities in Ukraine. On February 24, UN Secretary-General António Guterres criticized this move, saying it is inconsistent with the principles of the UN Charter, while the United States, European Union (EU), and Japanese governments decided to impose urgent sanctions. We, RECNA, strongly criticize Russia’s military invasion and express our deepest concern about the serious harm to the nuclear disarmament and non-proliferation regime and the increasing nuclear risk. We also affirm the risks posed by nuclear weapons and demand that nuclear disarmament is an imperative.

1. The risk of nuclear weapons use
It was reported that President Lukashenko of Belarus said on February 20 that Belarus was ready to host Russian nuclear weapons1 and, on February 24, President Putin made remarks that appeared to threaten nuclear strikes2. Even if they emphasized that their intentions are only for “deterrence” or “threat,” if the military confrontation is aggravated, the risk that nuclear weapons will be used may increase. Such nuclear threats pose the danger of fundamentally overthrowing international order and stability. In order to prevent confrontations among states from escalating to nuclear war, immediate suspension of military operations and dialogue among the countries concerned are urgently needed.

2. Risk of accidents at nuclear facilities in Ukraine
On February 24, it was reported that Russian troops had seized control of the Chernobyl nuclear power plant site in Ukraine3. Ukraine is said to have 15 nuclear power plants in operation at four sites, and nuclear power accounts for more than 50% of the total electricity generated. There are six nuclear power plants near the northern Belarusian border and nine near the southern Crimea region. Although a direct attack on these nuclear power plants is unlikely to occur, partly due to the fact that the Protocol Additional to the Geneva Conventions of 12 August 1949, and the Protection of Victims of International Armed Conflicts (Protocol I), 8 June 1977, prohibit attacks on nuclear power plants (also ratified by Russia), the safety of nuclear power plants may not be ensured in wartime4. There is also the danger of contingencies such as large-scale power outages caused by battles, or accidents due to the resistance or escape of nuclear power plant operators. In this context, too, the earliest possible cessation of military operations is imperative.

3. Risk of degrading the nuclear disarmament and non-proliferation regime
Immediately after the Cold War, with the collapse of the former Soviet Union, approximately 4,000 nuclear weapons were left in Ukraine5. These were not owned by the Ukrainian government, but in 1994, Ukraine asked for a security assurance as a condition for the return of all its nuclear weapons, leading to the Budapest Memorandum (1994)6, agreed by the United States, United Kingdom, and Russia. However, now that it has become clear that the promise was broken, the Ukrainian government must feel betrayed7. There are concerns that the fear of other countries facing security threats, including nuclear threats, may lead to nuclear proliferation. The damage to diplomatic efforts for the North Korean denuclearization and the restoring of the Iran nuclear deal will be immeasurable.

The Russian military invasion of Ukraine has deepened the gulf between the United States and Russia, and the future of disarmament among the nuclear superpowers has become even more uncertain. Military actions that do not even hesitate to threaten the use of nuclear weapons and shun opportunities for disarmament are acts in violation of the obligation to pursue negotiations in good faith for nuclear disarmament, as set forth in Article VI of the Nuclear Non-proliferation Treaty (NPT). Together with its betrayal of Ukraine, which has denuclearized and joined the NPT, Russia bears an extremely heavy responsibility. It is in Russia’s interest to prevent the increased risk of nuclear proliferation and the growing distrust of the NPT, and it should immediately stop military action and decide to restore Ukraine to its original state.

Abstract

This paper argues that there is no monolithic “United States perspective” when it comes to theories of nuclear stability, either structurally or during a crisis. Instead, the propensity of American policymakers to use or invest in nuclear weapons is heavily conditioned by their political and ideological orientation. There has always been a rough ideological divide between nuclear hawks (those tending to favor military coercion) and doves (those generally opposing signaling threats of force) in the United States, but the past several decades have seen more diversity in the types of views and preferences expressed in policy circles about strategic stability and the (dis)utility of nuclear weapons. This paper categorizes the various US perspectives on nuclear weapons as “arms-controllers,” who seek to reduce risks to strategic stability and view advanced conventional weapons as heightening the risks of nuclear use, “nuclear traditionalists,” who accept the logic of mutually assured destruction, “nuclear primacists,” who believe stability derives from nuclear superiority, escalation dominance, and the willingness to launch damage-limiting nuclear first-strikes, and “future-of-war” strategists, who de-center the role of nuclear weapons in US strategy in favor of a focus on precision-guided conventional munitions and delivery systems. These categorical distinctions, and which group holds the attention of policymakers, matters. The scope for US nuclear weapons use—and the propensity to engage in actions that trigger adversary nuclear considerations—narrows and widens depending on whose logic and preferences prevail both over time and in moments of crisis or shock.

POTENTIAL USE OF LOW-YIELD NUCLEAR WEAPONS
IN A KOREAN CONTEXT

Abstract

This report explores the potential uses of low-yield nuclear weapons in the context of a possible conflict on the Korean Peninsula. It starts with a definition of low-yield weapons—typically, weapons with yields of ten kilotons or less that are designed to be nonstrategic or “tactical” weapons used with shorter-range delivery systems, prepared for the purpose of attacking troops or battlefield infrastructure. The paper then reviews the history of United States legislation regarding low-yield weapons and describes three generic scenarios in which foes possessing low-yield weapons might choose, or not choose, to use them during a military conflict. Examples of radioactive fallout maps are provided based on HYSPLIT modeling for explosions of 0, 3 and 10 kilotons at a location in the Korean demilitarized zone at different times of the year. The arsenals of low-yield weapons in the states possessing nuclear weapons in Northeast Asia, as well as the United States, are compared, and seven possible “use cases” for low-yield nuclear weapons involving the Korean Peninsula are put forward.

Keywords:
Korean Peninsula, Nuclear Issue, DPRK, Denuclearization, Balance of Power
