The same logic that kept a nuclear war from breaking out between the United States and former Soviet Union is the best strategy to now pursue with North Korea, several scholars said Tuesday at Stanford.

The panel, convened at Stanford’s Center for International Security and Cooperation (CISAC), included political scientist Scott D. Sagan of CISAC; political scientist Mira Rapp-Hooper of Yale University; and political scientist Vipin Narang of MIT. The moderator was James D. Fearon, a political scientist at the Freeman Spogli Institute for International Studies. The event was titled “Can the U.S. Deter a Nuclear North Korea” and held in the William J. Perry Conference Room in Encina Hall.

Nuclear decision-making

The discussion revolved around whether North Korea will have the ability to strike the U.S. with nuclear warheads, and can the U.S. depend on a deterrence strategy like it did during the Cold War?

Deterrence theory holds that nuclear weapons are intended to deter other states from attacking with their nuclear weapons, through the promise of retaliation and possibly mutually assured destruction 

Sagan, who recently wrote an essay in Foreign Affairs magazine on the North Korea nuclear crisis, said he has come to decide deterrence is the best approach to the issue.

“I am not one who gladly listens to the siren song of nuclear deterrence,” he said, noting that while he is a self-described dove on disarmament issues, he is more hawkish on allowing countries to obtain nuclear weapons, which deterrence implies. “I accept deterrence reluctantly.”

In North Korea, he said, no military alternatives exist to solve the problem. For example, even if a decapitation strike were successful – and several U.S. attempts have failed in the past with regard to Saddam Hussein and Muammar Gaddafi – there’s no way to know if North Korean leader Kim Jong-un has already given his generals the green light to unleash nuclear or powerful conventional attacks in the case of his demise.

For Sagan, deterrence is a more complicated issue today than during the Cold War when the U.S. and U.S.S.R. were rational actors with thousands of nuclear weapons. He is especially concerned with the rhetoric and the preventive war suggestions emanating from the Trump Administration.

Senior U.S. military leaders, Sagan said, have a duty not to follow “impaired-decision making” that might come from the president. He invoked the prospect of using the Cabinet and the 25th Amendment to halt such an order and remove the president from office. Currently, he belives the nuclear decision process is problematic, as the president alone can directly order the Strategic Air Command to launch nuclear weapons.

Sagan advises that a revised nuclear chain of command should include both the U.S. Secretary of Defense and the U.S. Attorney General. A U.S. Senate hearing, led by Sen. Bob Corker, is actually studying the nuclear authorization process due to concerns with Trump's rhetoric and escalation of the North Korean issue.

“We need more checks on how we decide to use nuclear weapons,” said Sagan, who studies nuclear strategy, ethics and war, public opinion about the use of force, and nuclear non-proliferation and arms control.

He noted that U.S. National Security Advisor H.R McMaster recently criticized his predecessor, Susan Rice, for saying the U.S. could "tolerate" nuclear weapons in North Korea the same way we tolerated nuclear weapons in the Soviet Union​.

He quoted McMaster: “'A regime that poses a continuous threat to the its neighbors in the region and now may pose a threat, direct threat, to the United States with weapons of mass destruction? A regime that imprisons and murders anyone who seems to oppose that regime, including members of his own family, using sarin nerve gas in a public airport?'”

But Sagan said we have long tolerated such authoritarian regimes that have nuclear weapons. 

Stumbling accidentally into war with North Korea also seems like a rising risk. On Sept. 27, several U.S. service members and their families received a fraudulent “noncombatant evacuation operation” order via text and social media, he said. The fake notices were quickly reported up the chain of command and the U.S. issued a statement denouncing their validity – the perpetrators have not been found. But Sagan says it illustrates how easy it is to create a situation where North Korea felt a U.S. invasion and attack is imminent – and as a result, could choose to unleash a nuclear first strike.

‘Western fantasy’

Narang, who was once a CISAC visiting assistant professor, studies nuclear proliferation and strategy, South Asian security, and general security studies.

“Deterrence is your friend,” he said in explaining why it can work with North Korea. If the U.S. believes North Korea seeks to preserve its regime – a status quo intention – then deterrence theory works much like it did with the former Soviet Union.

On the other hand, if the U.S. believes North Korea has darker motives, such as reunifying the Korean peninsula through an invasion, then that perspective could lead to a U.S. first strike. Also, the existing U.S. demand of rolling back North Korea’s nuclear program – “denuclearization” – is a “Western fantasy.” They will not give up nuclear weapons, he said.

He said the U.S. does not like to be deterred from making a first strike – as in preventive war – but that is what it must accept if it decides to follow the deterrence course. North Korea, once it possesses an ICBM capable of hitting the U.S. mainland, would pose such a deterrence in the balance of power between the two countries.

“The good news is that deterrence can work, coupled with coercive diplomacy,” Narang said. “We know how to play this game.”

He believes Jong-un is a rational actor, though a cruel dictator. “There’s nothing to suggest he’s crazy.” Ultimately, he said, an effective deterrence policy depends on clarity, consistency, coherence and communications.

U.S. nuclear shield, alliances

An expert on security in the Asia-Pacific region and alliance politics, Rapp-Hooper talked about the U.S. relationships, especially with Japan and South Korea, and the “nuclear shield” over these countries that those agreements offer. As a result, neither country has developed nuclear weapons.

This dynamic, however, could change if a North Korean missile could reach the U.S., said Rapp-Hooper, who earned a bachelor’s degree in history at Stanford.

“North Korea is eroding U.S. security guarantees over time,” she said, adding that once those missiles are capable of hitting a U.S. city, would the U.S. government still protect Seoul from attack and let an American city be hit?

The Korean situation, Rapp-Hooper said, is much different than Europe in the Cold War, when such an American nuclear shield existed against a Soviet invasion. Many different U.S. agreements exist now than during that time; no U.S. nuclear weapons are forwardly deployed in northeast Asia, like in Europe then; and the unilateral threats coming from the Trump Administration are unprecedented in nuclear diplomacy.

On the latter point, she called it the “Trump multiplier” effect. “That’s the most exacerbating thing of all,” she said, noting that elements of the White staff are pushing a “better-use-it-now” or preventive attack approach, whereas Secretary of Defense James Mattis and Secretary of State Rex Tillerson see North Korea as more concerned with preserving its regime.

Sagan also pointed out how President Trump’s speech at the United Nations in September led to a realization among the North Koreans that they had no choice but to continue to develop nuclear weapons.

That’s when the president said, “’Rocket Man is on a suicide mission for himself and for his regime,’” Sagan noted.

​He then recalled Kim Jong Un’s response to Trump’s speech, quoting the North Korean leader: “’His remarks which described the U.S. option through straightforward expression of his will have convinced me, rather than frightening or stopping me, that the path I chose is correct and that it is the one I have to follow to the last.’”​

CISAC's Siegfried Hecker this week won the Dwight D. Eisenhower award from the American Nuclear Society. He received the honor, along with former Senator Richard Lugar (R-IN) and former Senator Sam Nunn (D-GA), for his "historic achievements in the advancement of nuclear nonproliferation, arms control, and peaceful uses of nuclear energy." The annoucement from the American Nuclear Society noted:

"Dr. Siegfried Hecker, an international expert in plutonium metallurgy, is being recognized for his nuclear non–proliferation efforts during and following his tenure as the Director of the Los Alamos National Laboratory. Dr. Hecker was part of a historic visit by a U.S. delegation to Sarov, Russia, known as Arazamas-16 during the Cold War.  This was the first visit to the closed city by the U.S., and it laid the foundation for a series of programs aimed at securing nuclear materials in Russia and all of its former republics. Dr. Hecker’s current research at Stanford University’s Center for International Security and Cooperation is focused on reducing the risks of nuclear terrorism worldwide, the nuclear challenges in India, North Korea, Pakistan, and the nuclear aspirations of Iran."

CISAC co-director Amy Zegart wrote the following essay in the Oct. 25 online edition of The Atlantic:

Pity the professionals. In the past month, President Trump has sideswiped certification of the Iran nuclear deal, sandbagged his own secretary of state’s diplomatic efforts with North Korea, and even provoked the ever-careful Senate Foreign Relations Committee Chairman, Bob Corker, to uncork his deepest fears in a series of bombshell interviews. “The volatility, is you know, to anyone who has been around, is to a degree alarming,” Corker told the Times earlier this month, revealing that many in the administration were working overtime to keep the president from “the path to World War III.” He doubled down on those comments a few weeks later, declaring that Trump, among other things, was “taking us on a path to combat” with North Korea and should “leave it to the professionals for a while.”

The professionals sure have their hands full. So far, the Trump Doctrine in foreign policy appears to consist of three elements: baiting adversaries, rattling allies, and scaring the crap out of Congress. The administration has injected strategic instability into world politics, undermining alliances and institutions, hastening bad trends, and igniting festering crises across the globe. “America first” looks increasingly like “America alone.” The indispensable nation is becoming the unreliable one. Even without a nuclear disaster, the damage inflicted by the Trump presidency won’t be undone for years, if ever.

But it’s also important to understand that today’s foreign-policy challenges— whether it’s Iran’s hegemonic ambitions in the Middle East, North Korea’s breakneck nuclear breakout, China’s rise, Russia’s nihilism, Europe’s populism and fragmentation, Syria’s civil war, or transnational terrorism and cyber threats—did not start with Trump. This is the most challenging foreign-policy environment any White House has confronted in modern history.

Three swirling complexities explain why.

Threat complexity

Take a look at any of the annual threat assessments issued by the Director of National Intelligence over the past few years. They will make your head spin. They are filled with rising states, declining states, weak states, rogue states, terrorists, hackers, and more. Bad actors don’t just threaten physical space these days. Adversaries are working on ways to cripple America in cyberspace and even outer space—by compromising all those satellite systems on which its digital society depends. In this threat landscape, the number, identity, magnitude, and velocity of dangers facing America are all wildly uncertain. Exactly how many principal adversaries does the United States have? Who are they and what do they want? What could they do to us? How are these threats changing and how can we keep up without spending ourselves into oblivion or leaving ourselves vulnerable to other nasty surprises? These are fundamental questions. There are no consensus answers. Uncertainty is what fuels America’s foreign-policy anxieties today.

The Cold War was different. Then, certainty was what fueled American foreign-policy anxieties. It was clear to all that the U.S. faced a single principal adversary. The Soviet Union had territory on a map and soldiers in uniforms. Thanks to U.S. intelligence, Soviet intentions and capabilities were fairly well understood. The threat landscape was deadly but slower-moving: Communists never met a five-year plan they didn’t like. And while superpower nuclear dangers were terrifying, they were also constraining in a helpful but insane sort of way. In 1961, President Kennedy invoked the specter of a “nuclear sword of Damocles, hanging by the slenderest of threads” over the earth. Every American foreign-policy decision had to consider the question: What would Moscow think of that? Today, the nuclear sword of Damocles is still hanging—indeed, China, India, Pakistan, and North Korea have all successfully tested nuclear devices since 1961—but no singular threat guides U.S. foreign policy as the Soviet Union once did.

Organizational complexity

As threats have grown more complex, organizational arrangements to deal with them have, too. Coordinating Soviet policy was one thing. Developing coherent U.S. foreign policy in the face of so much uncertainty across so many issues is quite another. Little wonder special advisers, envoys, commissions, boards, initiatives, czars, and new agencies have been growing like mushrooms. This may not sound so bad. But it is. Every new agency or czar or special arrangement says, “the regular process here ain’t working.” The crux of the problem is that bureaucracies are notoriously hard to kill or change. Ronald Reagan famously quipped that bureaucracy is the closest thing to immortal life on earth. Whenever a crisis hits, the natural response is to add a new organization and stir. But if today’s chief challenge is developing coherent, coordinated policy in the face of complexity, creating more organizations to coordinate doesn’t get you very far. Over time, the whole bureaucratic universe just keeps growing bigger, filled with obsolete organizations alongside new organizations; fragmented jurisdictions, overlapping jurisdictions, and unclear jurisdictions; and silos so specialized that nobody can see across all the key issues easily.

Cognitive complexity

Humans are not superhuman. Research finds that most people can remember at most seven items at a time, fewer as they grow older. Even the biggest brains have limits. In 2001, Peter Pronovost of Johns Hopkins noticed that highly trained medical teams at the university’s medical center were screwing up insertions of central line catheters, causing infections in critically ill patients at alarming rates. Why? Because they often forgot one of just five simple steps (like washing their hands) before starting the procedure. (Pronovost instituted a checklist that has since become widely used and is credited with saving thousands of lives.)

In foreign policy, too, the stakes are high and humans are frequently overloaded by complexity, resulting in catastrophic errors that nobody ever intended. One of the chief findings of the 9/11 Commission, for example, was that many inside the FBI simply didn’t know or couldn’t remember all the legal requirements and rules for sharing intelligence and law-enforcement information. Even the Bureau’s own 1995 guidelines were “almost immediately misunderstood and misapplied,” the commission concluded. As a result, clues to the terror plot emerged weeks before 9/11 but were marooned in different parts of the bureaucracy.

In 1935, an advanced bomber nicknamed “the Flying Fortress” crashed during a test flight. The Army Air Corps investigation found that the machine worked fine. The problem was the human. The airplane was so sophisticated, flying required the pilot to remember too many things, and he forgot one of them: unlocking the rudder and elevator controls during takeoff. It was “too much airplane for one man to fly,” one reporter later wrote. That crash sparked the invention of pilot checklists which have been used for nearly a century, transforming global aviation.

U.S. foreign policy is becoming too much airplane for one person to fly. “The professionals” surrounding Trump—Secretaries James Mattis and Rex Tillerson, Chief of Staff John Kelly, National-Security Adviser H.R. McMaster, and others—are trying to keep the whole thing from crashing with a pilot who has never flown before. Let’s hope they can.

America’s approach to the world is a complicated mess, for reasons that predate the current president.

If the U.S. abandoned the Iran nuclear deal, it would harm America’s credibility on nonproliferation issues and make it more difficult to solve the North Korean crisis, Stanford scholars say.

The Trump administration is soon expected to “decertify” or send the Iran nuclear agreement to Congress for reconsideration. Signed in 2015, the nuclear deal framework is between Iran and what is known as the “P5+1” group of world powers: the United States, United Kingdom, France, China, Russia and Germany.

Advocates of the deal say it helped avert a possible war with Iran and a Middle Eastern nuclear arms race. Critics say it will only delay Iran’s march toward a nuclear bomb. The agreement aims to limit Iran’s ability to create nuclear weapons; in return, Iran received relief from economic penalties and sanctions.

The Stanford News Service spoke with two experts about the deal.

• Siegfried Hecker is a top nuclear security expert, former Los Alamos National Laboratory director and senior fellow at the Center for International Security and Cooperation.
• Abbas Milani is the Hamid and Christina Moghadam Director of Iranian Studiesand affiliate at FSI’s Center on Democracy Development and the Rule of Law.

If the U.S. cancels the Iran nuclear deal, could Iran follow a similar path that North Korea has taken? 

Hecker: An important lesson the Trump administration should learn is from what happened in October 2002 when the Bush administration couldn’t wait to walk away from the Clinton administration’s “Agreed Framework” deal with Pyongyang. That led to North Korea withdrawing from the Nuclear Nonproliferation Treaty, expelling the international inspectors and building a nuclear bomb. Walking away from the Iran deal now could similarly open the doors for Tehran to build a nuclear bomb.

How might this change our relationships with other countries and nuclear powers?

Hecker: The other parties that signed the Iran deal are all strongly in favor of keeping the deal, so it will leave the U.S. even more isolated than it has already become. It is not clear what the effect would be in Israel where Prime Minister Benjamin Netanyahu opposes the deal, but where many voices favor it.

Are the inspection standards in this deal rigorous? 

Hecker: The deal has more stringent inspection regimes and rights than previous nuclear agreements. Some in the U.S. call for even more intrusive inspections, such as to defense sites, that essentially no country is willing to have inspected. I think the agreement was able to get more than I ever thought possible.

How is the deal perceived in Iran?

Milani: I think the critical point to know is that there is not one voice or view that reflects the hopes and aspirations of Iran. The radical conservatives among the clergy and the Islamic Revolutionary Guard Corps were critical of the deal. They condemned it as the most “shameful” agreement in modern Iranian history. They lambasted Foreign Minister Mohammad Javad Zarif and President Hassan Rouhani for having made far too many concessions. Ali Khamenei, the Supreme Leader, tried to keep a safe distance from the deal – lest he antagonize his badly needed and shrinking radical conservative base – and yet, at every major turn, endorsed it.

For the regime, faced with calamitous economic challenges, having the deal and ending the sanctions was an existential must. For the same reason, the vast majority of Iranians, facing the drudgeries of a dying economy, favored the deal. They also hoped that the deal would usher in new relations with the world and the U.S. – a possible harbinger for a more free Iran.

How would Iran likely react to a strict enforcement approach often urged by the Trump administration?

Milani: It is not clear what the Trump administration means by a more “strict enforcement.” The agreement has placed fairly rigorous limits on Iran’s nuclear activity given the unique abilities of the International Atomic Energy Agency (IAEA) to monitor the program. Might Iran cheat? It might, but no “strict” enforcement can eliminate such a possibility.

There are, moreover, areas that have by all accounts been consciously left ambiguous in the deal. Is, for example, Iran required to curtail its missile program or contain its regional activities? Iran is adamant that these provisions were never part of the deal. Finally, the Trump administration’s notion that Iran is not abiding by the “spirit” of the deal is hard to enforce. One side’s perceived spirit might be deemed by the other side as nothing but wishful thinking.

Are there ways the deal could be strengthened and Iran’s regional ambitions checked?

Milani: There surely are ways to strengthen any deal.  The first step is, by clear indication, that all sides will abide by it. The U.S. is now the only country in the agreement that has indicated its desire to abrogate the deal. You can’t strengthen a deal you no longer are a part of.

It will be a bonanza for the radical conservatives if the U.S. unilaterally walks away from the deal. Khamenei’s mantra that the U.S. can never be trusted will be confirmed, Iran will harvest the economic benefits of the end of sanctions and radical conservatives will be able to blame their own failed management on U.S. sanctions.
