NK estimated to have ability to produce 7 nuclear bombs a year

By Kim Jae-kyoung

A world-renowned nuclear scientist said that U.S. President Donald Trump must to talk to North Korean leader Kim Jong-un by sending an envoy to Pyongyang to avoid a nuclear catastrophe.

"I believe the first talks should be bilateral and informal by a presidential envoy talking directly to Kim Jong-un," said Siegfried S. Hecker, a senior fellow at the Center for International Security and Cooperation (CISAC) at Stanford University, in an interview.

"I believe both Seoul and Beijing would support such talks. These talks may then also help to build the foundation for renewed multilateral negotiations, which, first and foremost must involve South Korea, as well as China," he added.

Hecker, the co-director of CISAC from 2007 to 2012, has visited North Korea several times to assess the plutonium program at the Yongbyon Nuclear Scientific Research Center since 2004.

He stressed that it is most important to convey the message that nuclear weapons cannot be used under any circumstances.

"There is no such thing as a limited nuclear war. Any explosion of a nuclear device on the Korean Peninsula is a catastrophe of indescribable proportions," he said.

The internationally recognized expert in plutonium science, global threat reduction and nuclear security said that the Trump administration and the new South Korean government face the challenge of avoiding a nuclear detonation on the Korean Peninsula.

He believes that such an incident could result from a miscalculation or overconfidence by the Kim Jong-un regime as well as an accident with the nuclear weapons in the North.

"A conventional confrontation may turn nuclear with an inexperienced leader in charge," he said. "Or, in the case of instability in the North, who will control the nuclear weapons? These are serious concerns that must be addressed now," he added.

Hecker, who served as the director of the Los Alamos weapons laboratory in New Mexico, the birthplace of the atomic bomb, from 1986 to 1997, estimated that North Korea, although he is uncertain, may have sufficient material for 20 to 25 nuclear weapons.

NK's nuclear capabilities evolving 

He explained that the size of its nuclear arsenal depends primarily on how much plutonium and highly enriched uranium North Korea has produced.

"The sophistication of the arsenal depends primarily on nuclear testing. With five nuclear tests conducted over 10 years, North Korea is likely able to produce nuclear devices small enough to fit on missiles that can reach all of South Korea and Japan," he said.

He also estimated that the totalitarian country can produce sufficient plutonium and highly enriched uranium for six to seven bombs per year.

"However, all estimates are uncertain because we know little about the North's capacity to produce highly enriched uranium since it is not possible to monitor such facilities from afar," he said.

In his view, the world does not have to accept the reclusive country as a "nuclear weapons state," but it must be treated as a country with a nuclear arsenal.

"Whether we like it or not, North Korea is a country with nuclear weapons," he said. "The final aim is to have a denuclearized Korean Peninsula, but that will take time. It will have to be done in sequence of halt, roll back and then eliminate."

However, Hecker dismissed North Korea's claim that it has the capability to fire an intercontinental ballistic missile (ICBM) all the way to the U.S. mainland.

"I do not believe North Korea is capable of reaching the U.S. mainland with a nuclear-tipped missile today. It is working on developing such a capability, but it will likely take another five years or so," he said.

Hecker explained that it has not demonstrated all the aspects of necessary rocket technology or the ability to make a nuclear warhead small enough to be able to survive atmospheric reentry.

"Besides, to actually launch a nuclear warhead on an ICBM you must have complete confidence that it will not blow up on the launch pad," he added. "They cannot have such confidence based on their missile launch history."

When one thinks of the casualties of war, it is easy to imagine severed limbs, bullet holes, shrapnel, perhaps even sarin gas or Agent Orange. But in a recent Daedalus essay, Paul Wise argues that the most damaging health impacts of war are often indirect. Losing access to food supplies, medication and electricity can kill more people than battle itself. In this video by the American Academy of Arts and Sciences, Wise, a professor of pediatrics and Stanford Health Policy core faculty member, explains how fatal the indirect costs of war can be.

While the United States has no peers in conventional military power, it is especially vulnerable – as a free and democratic society – to cyber misinformation campaigns, a Stanford scholar says.

Herbert Lin, a senior research scholar for cyberpolicy and security at Stanford’s Center for International Security and Cooperation (CISAC), is the co-author of a new draft working paper that spells out the perilous risks facing democratic, wired-up countries around the world.

America’s adversaries are seeking “asymmetric” methods for social disruption, rather than direct military conflict, Lin said.

“Cyber warfare is one asymmetric counter to Western (and especially U.S.) military advantages that depend on the use of cyberspace,” wrote Lin and his co-author Jackie Kerr, a research fellow at the Lawrence Livermore National Laboratory.

This new type of cyber aggression is aimed at winning – and confusing – hearts and minds, the very control centers of human existence, Lin said.

As a result, “information/influence warfare and manipulation,” or IIWAM as Lin describes it, poses profound implications for Western democracies, even though much of it may not be illegal under international law. This approach is based on the deliberate use of information by one party on an adversary to confuse, mislead, and ultimately to influence the choices and decisions that the adversary makes.

A recent example in point would be the 2016 Russian hacking of the U.S. presidential election and the surge of so-called “fake news.”

Lin points out that while misinformation campaigns are not new, the technology to spread it far and wide globally is. He noted that the patron saint of distorting reality for war-like purposes is Sun Tzu, who wrote that, “The supreme art of war is to subdue the enemy without fighting.”

While traditional cyber attacks typically hit hard targets like computer systems, cyber “influence” campaigns are conducted over longer periods of time and rely on soft power – propaganda, persuasion, culture, social forces, confusion and deception, Lin said. 

Words and images

How does it work? Lin explains:

“Victory is achieved by A when A succeeds changing B’s political goals so that they are aligned with those of A.  But such alignment is not the result of B’s 'capitulation' or B’s loss of the ability to resist – on the contrary, B (the losing side) is openly willing.”  That is, such victory shares the focus on subverting the opponent’s will, though not on destroying his military forces.

The ammunition in these cyberspace battles are “words and images,” the kind that persuade, inform, mislead, and deceive so that the adversary cannot respond militarily. In the example of a “fake news” story, they often take place below legal thresholds of “use of force” or “armed attack,” and at least in an international legal sense, do not trigger a military response.

The target is the “adversary’s perceptions,” which reside in the “cognitive dimension of the information environment.” In other words, such cyber warfare focuses on “damaging knowledge, truth, and confidence, rather than physical or digital artifacts,” according to Lin. It is the “brain-space.”

Additionally, IIWAM injects fear, anger, anxiety, uncertainty, and doubt into the adversary’s decision making processes, he added.  Success is defined as altering such perceptions so the target makes choices favoring the aggressor.

“Sowing chaos and confusion is thus essentially operational preparation of the information battlefield – shaping actions that make the information environment more favorable for actual operations should they become necessary,” the researchers wrote.

These cyber manipulations often prey upon cognitive and emotional biases present in the psychological and mental makeup of human beings, Lin said. 

For example, media channels such as Fox News play to “confirmation bias” for individuals with a right-of-center orientation, and similarly for MSNBC for those with a left-of-center, orientation, he wrote. Confirmation bias is the tendency to interpret new evidence as confirmation of one's existing beliefs or theories.

Countering misinformation

“Naming and shaming” is probably ineffective against many nation states conducting cyber disinformation campaigns, Lin said. And the idea that a government like the U.S. can quickly respond to misinformation created in the private sphere is unlikely to be effective as well.

What, then, might work? Lin suggests new tactics are needed, as no existing approach seems adequate. For example, Facebook is deploying a new protocol for its users to flag questionable news sites.  Google has banned fake news web sites from using its online advertising service. Twitter, YouTube, and Facebook shut down accounts that they determine are promoting terrorist content.  He noted that a recent Facebook letter from CEO Mark Zuckerberg states that, “Our approach will focus less on banning misinformation and more on surfacing additional perspectives and information, including that fact checkers dispute an item's accuracy.”

But such measures are unlikely to stem the “rising tide of misinformation conveyed” through cyber warfare, Lin said, because they mostly require users to do additional mental work.  

Wired world riskier

Today’s Internet-driven Western world offers countless opportunities for cyber influence mischief, Lin wrote.

“Democracy has rested on an underlying foundation of an enlightened, informed populace engaging in rational debate and argument to sort out truth from fiction and half-truth in an attempt to produce the best possible policy and political outcomes,” Lin wrote.

Cyber manipulators have exploited an arguable gap between ideals and reality in democratic systems – “rendered it much more questionable” – through the tremendous reach and speed of misinformation, he said. Many countries cannot deal with the onslaught of such focused efforts. This serves to make the democratic process look weak and unstable in the eyes of its citizens. The same dynamic does not apply equally around the world.

“Cyber weapons pose a greater threat to nations that are more advanced users of information technology than to less-developed nations,” Lin wrote.

He said that less developed or authoritarian countries do not have much Internet infrastructure or that wield control over expression – North Korea is an example.

Anna Péczeli, a Stanton Nuclear Security Fellow at CISAC, wrote the following op-ed for the Bulletin of the Atomic Scientists:

What does the future hold for the US nuclear posture under President Trump? The last Nuclear Posture Review occurred in April 2009, when a 12-month review process was conducted to translate President Obama’s vision into a comprehensive nuclear strategy for the next five to 10 years. The review addressed several major areas: the role of nuclear forces, policy requirements, and objectives to maintain a safe, reliable, and credible deterrence posture; the relationship between deterrence policy, targeting strategy, and arms control objectives; the role of missile defense and conventional forces in determining the role and size of the nuclear arsenal; the size and composition of delivery capabilities; the nuclear weapons complex; and finally the necessary number of active and inactive nuclear weapons stockpiles to meet the requirements of national and military strategies.

Clearly, changes are afoot. On January 27, 2017, President Trump issued a presidential memorandum that mandated “a new Nuclear Posture Review to ensure that the United States nuclear deterrent is modern, robust, flexible, resilient, ready, and appropriately tailored to deter 21st-century threats and reassure our allies.” 

Looking ahead, the new administration should conduct this review through a broad, inter-agency process, involving the State and Energy departments, and allies as well. This approach offers several valuable benefits by broadening the focus from deterrence to non-proliferation, reassurance, and nuclear security.

The main role of the Nuclear Posture Review, or NPR, is to assess the threat environment, outline nuclear deterrence policy and strategy for the next 5 to 10 years, and align the country’s nuclear forces accordingly. Since the end of the Cold War, each administration has conducted its own NPR, but the process and the scope of the reviews were different in all three cases. 

The first NPR was conducted by the Clinton administration in 1994, and even though important senior positions have still not been appointed by the Trump White House, Trump's mandate suggests that their review might use it as a template for 2017. It was a bottom-up review, initiated by the Department of Defense, mostly focusing on a set of force structure decisions—such as the right size and composition of US nuclear forces, including the size of the reserve or so-called “ hedge” force. That review lasted for 10 months, and the Pentagon was in charge of the entire process, mainly focusing on deterrence requirements. 

In contrast, the 2001 NPR of the Bush administration was mandated by Congress, and it addressed a broader set of issues, including all components of the deterrence mix—nuclear and non-nuclear offensive strike systems, active and passive defenses, and the defense infrastructure. The Defense Department took the lead in this case just as before, but this time the Energy Department and the White House were also engaged in the process. As a result, the Bush NPR’s force structure requirements—how to size and sustain the country’s forces—were driven by four factors: assuring allies, deterring aggressors, dissuading competitors, and defeating enemies. 

The Obama administration’s 2010 NPR was also mandated by Congress, but the Defense Department was specifically tasked to conduct an inter-agency review. Besides the unprecedented level of such cooperation, a bipartisan Congressional commission also laid out a number of recommendations for the review process, many of which became part of the final text of the Obama review. Officials from State, Energy, and the Joint Chiefs of Staff were involved, as well as US allies who were regularly briefed during the different stages of the review. 

In the final phase of the 2010 NPR, the White House leadership made the decisions on the actual content of the nuclear posture. While the Clinton and the Bush reviews were largely conducted behind the scenes and only short briefing materials were published on the outcome, the Obama administration released an unprecedentedly long report on its nuclear posture review. 

These cases offer two models for a review process: It can be conducted by a small group of people in the most highly classified manner, or it can be a larger, relatively transparent inter-agency process. In the former approach, the final decisions are typically presented to the secretary of defense, the president, Congress, and allies. The problem is that this tends to be a one-sided approach, putting the main focus on deterrence and modernizations. 

Though it is effective and fast, the implementation of a Nuclear Posture Review requires all stakeholders to be on board with the new strategy. One of the most painful lessons of the Bush review was that because the White House and Defense failed to explain their new approach to the public, the military, and Congress, there was effectively a loss of leadership—which made procurement extremely difficult and caused major problems in the implementation of their strategy. 

On the other hand, involving all stakeholders and providing a balanced approach to nuclear strategy would support the goals of not just deterrence, but those of reassurance, non-proliferation, and nuclear security as well. Due to the involvement of the State Department, the 2010 NPR, for example, emphasized a number of policies which supported non-proliferation objectives and strengthened US negotiating positions at global arms control forums. One of these policies was the “negative security assurance,” which stated that the United States would not use or threaten to use nuclear weapons against non-nuclear weapon states that are party to the NPT and in compliance with their nuclear nonproliferation obligations. 

The other policy that was advocated by senior State Department officials was the so called sole-purpose posture—which means that nuclear weapons only serve to deter or respond to a nuclear attack, and they no longer play a role in non-nuclear scenarios. Although the sole purpose posture was eventually dropped and it was set only as a long-term objective, the Obama administration still reduced the role of nuclear weapons with the new negative security assurance, and it signaled its intent to continue this process with the promise of sole purpose. These steps supported US leadership at the 2010 Nuclear Non-Proliferation Treaty Review Conference and they contributed to the adoption of a consensual final document at the conference. 

This broader scope strengthens inter-agency cooperation, and ensures that all the departments that are affected by the NPR are on board with the strategy, which eases the implementation of the decisions. Besides, it also strengthens alliance relations by regular consultations. The Trump administration’s mandate did not include a specific timeline or format; consequently it will be mainly the responsibility of Defense Secretary James Mattis to decide on the framework. Though the presidential memorandum did not require an inter-agency process, it would be wise to conduct one.

Compared to 2010, the security environment has dramatically deteriorated: renewed tensions between NATO and Russia since the annexation of Crimea, China’s building of military bases in what had previously been international waters, significant military modernization efforts by both these states, and North Korea’s increasingly bellicose nuclear threats. All of these developments have created a serious deterrence and security challenge for the United States and its allies. Only a broader approach can address all relevant threats and create the necessary internal consensus for the funding and creation of a modern, robust, flexible, resilient, ready, and appropriately tailored nuclear arsenal.

Siegfried S. Hecker wrote the following essay for the U.S. News & World Report in an online discussion among seven experts regarding North Korea's nuclear situation:

The North Korean nuclear crisis continues to dominate the news, but it has been remarkably devoid of analysis. To resolve the crisis it is crucial to understand what nuclear capabilities North Korea has, how it acquired them, when and why.

What? A nuclear weapons arsenal requires bomb fuel, the ability to weaponize and the ability to deliver the bomb. Bomb fuel, namely plutonium or highly enriched uranium, is typically the most difficult to acquire. Plutonium is produced in reactors and uranium is enriched in centrifuges. The rate of production of bomb fuel constrains the size of the arsenal.

Uncertainty about U.S. intentions in Northeast Asia has increased fear that events could spin out of control in the region due to American disengagement. That engagement cannot be taken for granted, Shorenstein Fellow Thomas Fingar writes on the Stanford University Press blog, and it remains to be seen just how well regional political leaders adjust to the Trump administration’s evolving foreign policy.

The blog post highlights themes from his book Uneasy Partnerships: China’s Engagement with Japan, the Koreas, and Russia in the Era of Reform (Stanford, April 2017).
