Nuclear Risk
Paragraphs

Under the sponsorship of Stanford University, we designed a massive open online course (MOOC) to raise public consciousness about the past, present, and future dangers of nuclear weapons. Most individuals—and many policymakers—remain blissfully unaware that risks such as nuclear terrorism, a regional nuclear war, or a nuclear conflict started by accident are higher today than during the Cold War. Our course, Living at the Nuclear Brink: Yesterday and Today, successfully appealed to a broad audience and increased discourse about this existential threat facing humankind. Consequently, we believe our experience lends insight into MOOCs in general, and demonstrates that they can be a powerful tool to create an informed citizenry.

Researchers urge Moon Jae-in to form a close working relationship with Donald Trump and to establish a new special envoy role for North Korea policy emulating the “Perry Process”

Researchers from the Shorenstein Asia-Pacific Research Center (APARC) said they are optimistic about the election of South Korean president Moon Jae-in who assumed office last week following waves of protest across the country.

Now that the vacancy left in the wake of former President Park Geun-hye’s impeachment has been filled, the South Korean government needs to work to strengthen bilateral relations with the United States amid escalating tensions in Northeast Asia, they said.

The Moon administration should immediately engage U.S. President Donald Trump and his senior staff at the White House and government agencies, said Kathleen Stephens, the William J. Perry Fellow at Shorenstein APARC.

“Moon would do well to establish a personal relationship with Trump,” said Stephens, who was U.S. ambassador to South Korea from 2008 to 2011. “The new administration must set up a meeting as early as possible and be ready to engage on a range of issues.”

“In a sense, Moon has to play catch-up,” said Shorenstein APARC Director Gi-Wook Shin, who noted that Trump already held in-person meetings with other Asian heads of state in the United States, including summits with Chinese President Xi Jinping and Japanese Prime Minister Shinzo Abe.

Shin added that a coherent U.S. strategy toward Asia and senior staff appointments in the State and Defense Departments would also aid in supporting the foundation upon which the South Korean and American governments work together on policy challenges, especially North Korea.

North Korea’s nuclear and missile capabilities have become more and more advanced over the past few months, and provocations have continued to ratchet up, including its firing of a ballistic missile that landed in the sea near Russia on Sunday and repeat threats to conduct a sixth nuclear test.

The Moon administration must focus on establishing trust and cooperation with the Trump administration because it is the only pathway to finding a resolution to North Korea’s program, said Siegfried Hecker, a senior fellow at the Center for International Security and Cooperation, an additional center in the Freeman Spogli Institute.

“Any solution must be compatible with the interests of Seoul, but it has to be done in concert with Washington to get Pyongyang’s attention,” said Hecker, who served as director of the Los Alamos National Laboratory and has traveled to North Korea seven times since 2004 to survey its nuclear facilities.

During the campaign, Moon repeatedly spoke of his proposals to reengage the North Korean regime, such as holding talks with its leader Kim Jong-un and re-opening Kaesong Industrial Complex, a joint economic zone on the North Korean side of the border.

Stephens and Shin said Moon’s proposals for North Korean engagement would be a step in the right direction if pursued in due time and led under the direction of a special envoy from South Korea emulating the American “Perry Process.”

The Perry Process, proposed by former U.S. Secretary of Defense William Perry and implemented in the late 1990s under the Clinton administration, entails the appointment of a senior-level, bipartisan representative to pursue a two-track approach of engagement through joint projects and of continued dialogue on denuclearization with North Korea.

Appointing one person in South Korea to lead North Korea policy would help centralize and streamline its organization, which currently requires coordination of activities across dozens of government agencies, the two researchers noted.

“We recognize that establishing such a position and filling the position would be far from easy,” said Shin, co-author of the study Tailored Engagement. “But the magnitude of the nuclear crisis requires restructuring the way in which the South Korean government deals with North Korea, achieving domestic consensus, and shoring up international support for its efforts.”

The United States, China, Japan and Russia are the key international countries concerned with the peace and stability of Northeast Asia, yet South Korea has both an acute need and the potential to assume greater leadership of North Korea policy, said Shorenstein APARC Fellow Thomas Fingar.

China, as North Korea’s largest trade partner, exercises influence over North Korea by maintaining a commercial relationship in the hope of avoiding a collapse of the regime. Yet, its leverage only goes so far, he added.

The Moon administration should consider the limits of Chinese influence before making policy decisions regarding North Korea, Fingar said, for example, whether to freeze or remove the U.S. anti-ballistic missile system, Thermal High Altitude Area Defense (THAAD), deployed last April in South Korea, which the Chinese government strongly opposed.

“There is little that Beijing can or will do that would persuade Pyongyang to be more receptive to initiatives from Seoul than it would otherwise be,” said Fingar, a China specialist who served as chairman of the U.S. National Intelligence Council. “Seoul should not ‘pay’ much to obtain Chinese assistance because China already supports reengagement and would not do more no matter what Seoul offered as an inducement.”

It is of vital importance the Moon administration seeks to strengthen trilateral cooperation between South Korea, Japan and the United States, and to consider holding a summit to address areas of collaboration, all of which would function alongside the China-Japan-South Korea trilateral structure toward creating stability in the region, according to Daniel Sneider, associate director for research at Shorenstein APARC.

“Such cooperation is essential to the security of the region – without it, the United States cannot fulfill its obligation to defend South Korea against the threat posed by North Korea,” said Sneider, who leads the Divided Memories and Reconciliation research project. “Moreover, it’s in the interest of all three countries to tighten such cooperation to balance the rise of China.”

The Moon administration should, above all else, take time to consider its first steps despite pressures to perform early, said Michael Armacost, a fellow at Shorenstein APARC who held a 24-year career in the U.S. government.

“Getting things right is more important than making a quick splash,” said Armacost, a former U.S. undersecretary of state for political affairs. “I would advise any new president to proceed at a deliberate pace, focusing particularly on the key personal issues first, and consulting widely before enunciating major policy departures.”

Shorenstein Asia-Pacific Research Center (APARC) Director Gi-Wook Shin spoke with Yonhap News about the situation on the Korean Peninsula, following a visit to U.S. Pacific Command with a delegation of scholars from the Freeman Spogli Institute for International Studies.

While there, U.S. officials conveyed that the United States has the capability to strike North Korea should the president make that call.

U.S. officials said that North Korea had already moved into the “red zone,” and that the Trump administration has the view that it cannot miss a window of opportunity to stop the nuclear and missile program before it advances further.

Shin also said he believed that the Trump administration holds a view that the policy of “strategic patience” failed under the Obama administration, and that growing tensions on the Peninsula have compelled the Trump administration to consider – with greater plausibility – the option of a preemptive military strike.

Regional tensions have risen in the midst of impending political shifts in South Korea, where a new president will assume office following a snap election this May, and in China, where the Party Congress will meet to appoint new senior leadership of the Chinese Communist Party this fall.

Whoever becomes president in South Korea should place relations with North Korea at the top of the agenda and consider sending an envoy early on to meet its leader Kim Jong-un in-person, Shin said.

The Yonhap interview can be viewed in Korean, and a shorter version, in English. A related analysis piece is also available on MK News (in Korean).

President Trump hosted Chinese President Xi Jinping last week at Mar-a-Lago for their first meeting which set out to address economic, trade and security challenges shared between the two countries. Shorenstein Asia-Pacific Research Center (APARC) experts offered analysis of the summit to various media outlets.

In advance of the summit, Donald K. Emmerson, an FSI senior fellow emeritus and director of the Southeast Asia Program, wrote a commentary piece urging the two leaders to prioritize the territorial disputes in the South China Sea in their discussions. He also suggested they consider the idea of additional “cooperative missions” among China, the United States and other countries in that maritime area.

“A consensus to discuss the idea at that summit may be unreachable,” Emmerson recognized in The Diplomat Magazine. “But merely proposing it should trigger some reactions, pro or con. The airing of the idea would at least incentivize attention to the need for joint activities based on international law and discourage complacency in the face of unilateral coercion in violation of international law.”

Kathleen Stephens, the William J. Perry Fellow in Shorenstein APARC’s Korea Program, spoke to the Boston Herald about U.S. policy toward North Korea and a potential role for China in pressuring North Korea to hold talks about denuclearization. She addressed the purported reports that the National Security Council is considering as options placing nuclear weapons in South Korea and forcibly removing North Korean leader Kim Jong-un from power.

“The two options have been on the long list of possible options for a long time and they have generally been found to have far too many downsides,” Stephens said in the interview.

Writing for Tokyo Business TodayDaniel Sneider, the associate director for research at Shorenstein APARC, offered an assessment of the summit. He argued that two events - the U.S. airstrike on an airbase in Syria following the regime's chemical weapons attack and the leaked reports about tensions between White House staff - shifted the summit agenda and sidelined, at least for now, talk of a trade war between China and the United States.

“Instead of a bang, the Mar-a-Lago summit ended with a whimper,” Sneider wrote in the analysis piece (available in English and Japanese). “On the economy, the summit conversation was remarkably business-as-usual, with President Trump calling for China to ‘level the playing field’ and a vague commitment to speed up the pace of trade talks. When it came to North Korea…the two leaders reiterated long-standing goals of denuclearization but ‘there was no kind of a package arrangement discussed to resolve this.”

Abstract: High-security organizations around the world face devastating threats from insiders—trusted employees with access to sensitive information, facilities, and materials. From Edward Snowden to the Fort Hood shooter to the theft of nuclear materials, the threat from insiders is on the front page and at the top of the policy agenda. Insider Threats offers detailed case studies of insider disasters across a range of different types of institutions, from biological research laboratories, to nuclear power plants, to the U.S. Army. Matthew Bunn and Scott D. Sagan outline cognitive and organizational biases that lead organizations to downplay the insider threat, and they synthesize "worst practices" from these past mistakes, offering lessons that will be valuable for any organization with high security and a lot to lose.

About the Speakers: Matthew Bunn is a Professor of Practice at Harvard University's John F. Kennedy School of Government. His research interests include nuclear theft and terrorism; nuclear proliferation and measures to control it; the future of nuclear energy and its fuel cycle; and policies to promote innovation in energy technologies. Before joining the Kennedy School in January 1997, he served for three years as an adviser to the Office of Science and Technology Policy, where he played a major role in U.S. policies related to the control and disposition of weapons-usable nuclear materials in the United States and the former Soviet Union, and directed a secret study for President Clinton on security for nuclear materials in Russia.

Scott S. Sagan is the Caroline S.G. Munro Professor of Political Science, the Mimi and Peter Haas University Fellow in Undergraduate Education, and Senior Fellow at the Center for International Security and Cooperation and the Freeman Spogli Institute at Stanford University. He also serves as Project Chair for the American Academy of Arts and Sciences’ Initiative on New Dilemmas in Ethics, Technology, and War.

Abstract: Under what conditions could the United States control escalation in a conventional conflict with a nuclear-armed adversary? The possibility that a dispute between the U.S. and a nuclear-armed opponent remains a contingency policy-makers and military planners should consider. There is growing work on the pathways to nuclear escalation during a conventional conflict, but less on how these armed disputes could end. This paper will explore some of the conditions that favor successful escalation management and the conditions that could make escalation control extremely difficult. The paper also assesses possible U.S. responses to nuclear use by an adversary.

Abstract: Throughout the Cold War, Japanese leaders and policymakers have generally been careful to reflect the public’s firm opposition to anti-nuclear sentiment. However, the turn of the 21st century has witnessed a remarkable shift in the political debate, with élites alluding to a nuclear option for Japan. This sudden proliferation of nuclear statements among Japanese élites in 2002 has been directly linked by Japan watchers to the breakout of the second North Korean nuclear crisis and the rapid buildup of China’s military capabilities. Is the Japanese perception of this double military threat in Northeast Asia really the main factor that triggered this shift in the nuclear debate? This paper argues that Japanese élites’ behavior rather indicates that the new threats in the regional strategic context is merely used as a pretext to solve a more deep-rooted and long-standing anxiety that stems from Japan’s own unsuccessful quest for a less reactive, and more proactive post-Cold War identity. 

About the speaker: Sayuri Romei is a Nuclear Security Predoctoral Fellow at CISAC for 2016-2017 and a doctoral candidate in international relations at Roma Tre University in Rome, Italy. Her dissertation focuses on the evolution of Japanese élites’ nuclear mentality in the postwar era, looking at its ambivalent nuclear history and exploring how the country’s nuclear latency was seen by the United States throughout the Cold War. She holds a BA in English Language and Literature from the University of Sorbonne Nouvelle Paris III, a BA in international relations from the University of Roma La Sapienza, and an MA in international relations from Roma Tre University. Her fellowship at CISAC is sponsored by the MacArthur Foundation.
