A shadowy terror group smuggles a crude nuclear bomb into the United States, then detonates it right in the heart of Washington D.C., setting off a 15 kiloton explosion.

Eighty thousand Americans are killed instantly, including the president, vice president and most of the members of Congress, and more than a hundred thousand more are seriously wounded.

News outlets are soon broadcasting a message they’ve all received from a group claiming responsibility.

It says there are five more bombs hidden in five different cities across the America, and one bomb will be set off each week for the next five weeks unless all American troops based overseas are ordered to immediately return to the U.S. homeland.

The nation is thrown into chaos, as millions scramble to flee the cities, clogging roads and choking telecommunications systems.

The stock market crashes, before trading is halted altogether.

Martial law is declared, amid widespread looting and violence.

That was just one of the nightmare scenarios for a potential nuclear disaster that former U.S. Secretary of Defense William J. Perry vividly described as he delivered the Center for International Security and Cooperation’s annual Drell Lecture on Wednesday.

“My bottom line is that the likelihood of a nuclear catastrophe today is greater than it was during the Cold War,” Perry said.

Most people were “blissfully unaware” of the danger that simmering conflicts in geopolitical flash points around the globe – including Russia, China, North Korea, Iran and Pakistan – could easily turn nuclear, Perry told the Stanford audience.

A new nuclear arms race with Russia

Perry said he had tried to foster closer cooperation between the U.S. and Russia when he headed the Pentagon during the mid ‘90s and helped oversee the joint dismantling of four thousand nuclear weapons.

“When I left the Pentagon, I believed we were well on the way to ending forever that Cold War enmity, but that was not to be,” he said.

William J. Perry shares a video depicting the threat of nuclear terrorism with a Stanford audience.

Since then, relations between the West and Russia have soured badly, prompting Russia to modernize its nuclear arsenal and assume a more aggressive nuclear posture.

“They’re well advanced in rebuilding their Cold War nuclear arsenal, and it is Putin’s stated first priority,” Perry said.

“And they have dropped their former policy of no first use of nuclear weapons, and replaced it with a policy that says nuclear weapons will be their weapon of choice if they are threatened.”

While Perry said he believed Russian president Vladimir Putin did not want to engage in a military conflict with NATO forces, he said he was concerned about the possibility of Russia making a strategic miscalculation and stumbling into a conflict where they might resort to the use of tactical nuclear weapons.

“If they did that there’s no way of predicting or controlling the escalation that would follow thereafter,” Perry said.

Chinese economic problems increasing tensions

In Asia, a slowing Chinese economy could exacerbate domestic political tensions over issues such as wealth inequality and pollution, and encourage Chinese leaders to divert attention from problems at home by focusing on enemies abroad.

“China has had more than 10 percent growth now for almost three decades, but I think there’s trouble ahead,” Perry said.

“The time-proven safety valve for any government that’s in trouble is ultra-nationalism, which in the case of China translates into anti-Americanism and anti-Japanese.”

China has seen a major growth in military expenditures over the last decade, and it has used that investment to build a blue water navy and develop effective anti-ship missiles designed to drive the U.S. Navy hundreds of miles back from the Chinese coastline.

One potential flash point for a conflict between China and the U.S. are the artificial islands that China has been building in the disputed waters of the South China Sea.

“In a sense, China is regarding the South China Sea as a domestic lake, and we regard it and most other countries regard it as international waters, so their actions have been challenged by the U.S. Navy and will continue to be challenged,” Perry said.

North Korea’s growing nuclear threat

Meanwhile, China’s neighbor North Korea has continued to defy the international community and conducted another nuclear test in January.

“North Korea is today building a nuclear arsenal, and I would say clearly it’s of the highest priority in their government, and they have adopted outrageous rhetoric about how they might use those nuclear weapons,” Perry said.

William J. Perry delivers the Drell Lecture in an address entitled "A National Security Walk Around the World."

“These missiles today have only conventional warheads that are of no significant concern, but they are developing nuclear warheads,” Perry said.

“They already have developed a nuclear bomb, and the latest test, as well as tests to come, will be designed to perfect a bomb small enough and compact enough and durable enough to fit into a warhead. If they succeed in doing that, then the bluster will become a real threat.”

Perry said he hoped China and the United States could combine forces and adopt a “carrot and stick” diplomatic approach to force North Korea to abandon its nuclear weapons program – with the United States offering aid and international recognition, and China threatening to cut off supplies of food and aid.

He said he expected to see “more acting out” from the North Korean regime in the coming months, in the form of further nuclear and rocket tests.

Like it or not, the Iran deal is the only deal we’ll get

The landmark deal reached last year, where Iran agree to curtail its nuclear program in exchange for the lifting of economic sanctions, was a better resolution than Perry had expected to the negotiations, but it has met with significant resistance from groups he described as “strange bedfellows.”

“The opposition in Israel and the United States opposed the deal because they fear it will allow Iran to get a bomb,” Perry said.

“Whereas the opposition in Iran opposed the deal because they fear it will prevent Iran from getting a bomb. Both cannot be right.”

Many Republican presidential hopefuls have publicly stated on the campaign trail that they would withdraw from the deal if they got elected to the White House, but Perry said that would be a strategic mistake.

“The opposition in the United States has a simple formula – we should withdraw from the deal, we should reinstate sanctions, and we should renegotiate a better deal,” Perry said.

“Let me be as blunt as I can, this is a pure fantasy. There is not the remotest possibility that the sanction could be reapplied if the United States withdraws from this deal, because the day we withdraw from the deal, our allies are gone, the sanctions are gone, there will be no renegotiations without sanctions, so this deal, like it or not, is the only deal we will ever get.”

Another “Mumbai” attack could spark regional nuclear war

Nuclear rivals India and Pakistan have more than a hundred nuclear weapons on each side, as well as the missiles to deliver them, and a conventional military conflict between them could quickly escalate into a regional nuclear war, Perry said.

Another large-scale terror attack, like the coordinated assault in Mumbai that killed more than 163 people in 2008, could lead India to retaliate militarily against Pakistan (which India blames for encouraging the terror groups operating in Pakistani territory).

Perry said he was concerned that Pakistan would then use tactical nuclear weapons against invading Indian troops, and that India might then respond with a nuclear attack of its own on Pakistan.

“So this is the nightmare scenario of how a regional nuclear war could start,” Perry said.

“A nightmare that would involve literally tens of millions of deaths, along with the possibility of stimulating a nuclear winter that would cause widespread tragedies all over the planet.”

A ray of hope

Despite all the potential for nuclear disaster in the current geopolitical environment, Perry said he was still hopeful that nuclear catastrophe could be avoided.

"While much of my talk today has a doomsday ring to it, that truly is not who I am,” Perry said.

“I’m basically an optimist. When I see a cloud, I look for a ray to shine through that cloud.”

One important step toward reducing the nuclear threat would be improving relations between the U.S. and Russia, he said.

“My ray of sunshine, my hope, is I believe we can still reverse the slide in U.S. Russia relations, he said.

“We must begin that by restoring civil dialog. We must restore cooperation between the United States and Russia in areas where we have mutual interest…If we succeed in doing that, then we can work to stop and reverse the drift to a greater and greater dependence on nuclear weapons.”

Perry ended his speech by urging the audience to keep striving to rid the world of the threat of nuclear weapons.

“We must pursue our ideals in order to keep alive our hope – hope for a safer world for our children and for our grandchildren,” he said.

The rise of China as a global and regional power has created areas where the interests of China and the United States overlap in competition, the senior U.S. military commander in the Pacific told a Stanford audience. But Admiral Samuel Locklear III, the commander of U.S. Pacific Command (USPACOM), rejected the traditional realpolitik argument, which predicts inevitable confrontation between the United States, a status quo power, and China, a rising power.

“Historians will say this will lead to conflict,” Locklear said, during an address at the Walter H. Shorenstein Asia-Pacific Research Center last Friday. “I don’t believe it has to.”

The United States and China have a “mutual skepticism of each other,” the Pacific Commander acknowledged, but he characterized the relationship as “collaborative, generally.”

He said the dangers of direct military confrontation between the two powers is low, but warned against Chinese tendencies to perceive the United States as engaged in an effort to ‘contain’ the expansion of China’s influence. Instead, Locklear urged China to work with the United States to build new security and economic structures in the region.

Economic interdependence between the countries makes it impossible for the two countries to avoid working together, he told the seminar, co-sponsored by the Center for International Security and Cooperation and the Freeman Spogli Institute for International Studies at Stanford University.

He said that China has also benefited from the security environment that the United States has helped shape and maintain in the region.

Locklear reminded the audience of the central importance of the vast area under his command, which stretches from the Indian subcontinent across the vast Pacific Ocean. More than nine out of 10 of the largest ports in the world are in the Asia-Pacific region, and over 70 percent of global trade passes through its waters. The U.S. rebalance to Asia, a policy pursued by the Obama administration as early as year 2009, largely happened because of the economic and political importance of that area.

The mutual interest in economic prosperity depends, however, on a stable security environment. Washington has an interest in maintaining the structure of security that has ensured peace for the last few decades. Beijing seeks to change the status quo, to build a regional system that reflects its growth as a power.

Locklear called on China to work with the United States and other nations in the region, such as Japan and Australia, as well as the countries of Southeast Asia, to take the current “patchwork quilt” of bilateral and multilateral alliances and build a basis to maintain economic interdependence and security. He pointed to the U.S.-led effort to form a Trans-Pacific Partnership as a 12-nation economic structure, which could eventually include China.

“We want China to be a net security contributor,” he said, “And my sense is that both the United States and the nations on the periphery of China are willing to allow China to do that – but with circumstances.” He said conditions for the United States included open access to shared domains in sea, air, space and cyberspace.

The Pacific Commander cautioned against the danger, however, of unintended conflict, fueled by territorial disputes and Chinese assertiveness that worries its neighbors. Locklear stressed the need for more dialogue, including among the militaries in the region, an effort that the U.S. Pacific Command is currently carrying out.

“There’s a trust deficit in Asia among the nations, as it relates in particular to China,” he said.

Relations have been so icy that the top political leaders of Japan and China didn’t meet for nearly two years, only breaking the divide for a 20-minute meeting at the Asia-Pacific Economic Summit (APEC) in Beijing last month.

Refusing to engage at the highest level has made it difficult for countries to work on solutions to shared problems. The region now sees a confluence of old and new challenges that could threaten global stability if ill-managed, said Locklear, who has led the U.S. military command in the Pacific since 2012.                 

For decades, China and Japan have been at odds about sovereignty claims over islands in the East China Sea. In the past, during the time of Deng Xiaoping’s rule in China, the two countries agreed to, as Deng reportedly put it, ‘kick the issue into the tall grass’ for future generations to deal with it. These disputes have resurfaced in recent years, threatening to trigger armed conflict between the air and naval forces of the two countries.

Locklear said he believed that China and Japan would avoid inadvertent escalation, thanks to improved communications and tight command and control over their forces. But he also warned  that at least seven nations have conflicting claims in the South China Sea, which could easily escalate into direct conflict.

These situations, paired with an upsurge in Chinese military spending and the growing belief that the United States is a declining power, raise doubts about China’s intentions in the region. China’s Asian neighbors increasingly question the intensions of the world’s most populous nation, and second largest economy.

“Is it a return to the old days where you had basic tributary states? Is that the model that China is looking for? Or is it a 21^st century model?”

Locklear said China and other nations in the Asia-Pacific, as well as the United States, need to work harder to form shared views and consensus, particularly among those who “own the guns.”

Dialogue and interactions among the militaries are crucial, especially those who are called upon to make quick decisions during a possible flashpoint, for instance an accidental clash of boats or planes.

“Trust really does fall in many ways to military leaders to get it right and to lead, to some degree, the politicians and the diplomats,” he said. Locklear spoke of a tangible example of collaboration in the Rim of the Pacific Exercise, also known as RIMPAC, hosted by USPACOM. Twenty-two countries participate in the world’s largest maritime warfare exercise in Hawaii, which this year included naval forces from China.

“Does it fix those friction points? No, it doesn’t.” But, Locklear concluded, “We hope that this kind of thing opens the door for future interaction.”

Perception can often trump facts in politics, and the topic of security in East Asia isn’t exempt from this reality, exemplified by the dominance of China’s “rise” and Japan’s  “ramped up” defense posture in current policy debates. Yet, those dynamics create a need as well as an opportunity for increased multilateral engagement, says Thomas Fingar, the Oksenberg-Rohlen Distinguished Fellow at the Freeman Spogli Institute for International Studies.

“Developments in China and Japan should be viewed as creating new opportunities and imperatives to deepen multilateral co-operation,” Fingar writes in a Global Asia essay.

“It would be a mistake to view them only as the cause of eroding confidence in the co-operative mechanisms that remain critical to peace and prosperity in the region.”

China’s rise has actually been a result of policies supported by the United States and other countries, despite prevailing commentary that they are intended to “contain” China, he says. In fact, Beijing’s rise was achieved by working within the rules-based international system, not outside of it.

China’s actions and growing power, especially military power, are compelling other regional actors, notably Japan, to reconsider their strategic situation. The reinterpretation of defense policy guidelines proposed by the Abe government is a long-delayed response to China’s military buildup, not an effort to remilitarize as a popular narrative holds. Fingar says the proposed relaxation of self-imposed policy constraints on Japan’s military forces could help pave the way for a future collective security arrangement in Northeast Asia.

So, where does this leave the U.S.-South Korea relationship?

He says the two countries can maintain their bilateral commitments while also deepening partnerships with, and between China and Japan. Both the United States and South Korea can help push for improved ties on trade and regional security issues. 

“We need continued bilateral – and increased multilateral – co-operation,” he says, particularly, “to mange the challenges of a nuclear-armed North Korea.”

Karl Eikenberry, a William J. Perry Fellow in International Security at CISAC and Shorenstein APARC Distinguished Fellow in the Freeman Spogli Institute, says we mustn’t assume that tensions between China, a rising power, and the United States, a status quo power, will lead to conflict, in American Review.

He says the Thucydides Trap, a term derived from the Athens-Sparta dynamic which eventually lead to conflict more than 2,400 years ago, would be largely misapplied if used to describe the current context of U.S.-China relations.

“While it is generally true that struggles between rising and status quo powers historically have led to war, the various cases of the past – and Athens-Sparta in particular – are quite different from each other and certainly from today’s rivalry between the United States and China,” Eikenberry writes.

While the future of U.S.-China relations is uncertain, and if mismanaged, could lead to conflict, analysts in both countries would be unwise to assume a re-enactment of the Peloponnesian War.

CISAC Co-Director Amy Zegart writes in The American Interest that a strong and rising China, as well as a weak an unstable one, should concern the United States. But perhaps most troubling is the uncertainty about which scenario will eventually play out, and Washington’s strategic orientation toward Europe and the Middle East.

CISAC Co-Director Amy Zegart writes in The American Interest that the United States should be concerned about both a strong and rising China, as well as a weak and unstable one. But perhaps most troubling of all, she writes, is the uncertainty about which scenario will eventually play out – and Washington’s strategic orientation toward Europe and the Middle East.

“Today opinions range between nervous hope that everything will turn out all right to outright fear that things will be worse than we can possibly imagine,” she says. “Part of the fear stems from the fact that that the U.S. and China are both literally and figuratively worlds apart, with vastly different political and cultural histories.”

Regardless of these vast differences and uncertainties in China, Zegart argues, Asia will be the most important strategic region for American national security in the 21^st century.
