Space is more important than ever for the security of the United States, but it’s almost like the Wild West in terms of behavior, a top general said today.

Air Force Gen. John Hyten, commander of the U.S. Strategic Command, spoke Jan. 24 at Stanford’s Center for International Security and Cooperation. His talk was titled, “U.S. Strategic Command Perspectives on Deterrence and Assurance.”

Hyten said, “Space is fundamental to every single military operation that occurs on the planet today.” He added that “there is no such thing as a war in space,” because it would affect all realms of human existence, due to the satellite systems. Hyten advocates “strategic deterrence” and “norms of behavior” across space as well as land, water and cyberspace.

Otherwise, rivals like China and Russia will only threaten U.S. interests in space and wreak havoc for humanity below, he said. Most of contemporary life depends on systems connected to space.

Hyten also addressed other topics, including recent proposals by some to upgrade the country’s missile defense systems.

“You just don’t snap your fingers and build a state-of-the-art anything overnight,” Hyten said, adding that he has not yet spoken to Trump administration officials about the issue. “We need a powerful military,” but a severe budget crunch makes “reasonable solutions” more likely than expensive and unrealistic ones.

On the upgrade front, Hyten said he favors a long-range strike missile system to replace existing cruise missiles; a better air-to-air missile for the Air Force; and an improved missile defense ground base interceptor.

‘Critically dependent’

From satellites to global-positioning systems (GPS), space has transformed human life – and the military – in the 21st century, Hyten said. In terms of defining "space," the U.S. designates people who travel above an altitude of 50 miles as astronauts.

As the commander of the U.S. Strategic Command, Hyten oversees the control of U.S. strategic forces, providing options for the president and secretary of defense. In particular, this command is charged with space operations (such as military satellites), information operations (such as information warfare), missile defense, global command and control, intelligence, surveillance, and reconnaissance, global strike and strategic deterrence (the U.S. nuclear arsenal), and combating weapons of mass destruction.

Hyten explained that every drone, fighter jet, bomber, ship and soldier is “critically dependent” on space to conduct their own operations. All cell phones use space, and the GPS command systems overall are managed at Strategic Command, he said.

“No soldier has to worry about what’s over the next hill,” he said, describing GPS capabilities, which have fundamentally transformed humanity’s way of life.

Space needs to be available for exploration, he said.

“I watch what goes on in space, and I worry about us destroying that environment for future generations.” He said that too many drifting objects and debris exist – about 22,000 right now. A recent Chinese satellite interception created a couple thousand more debris objects that now circle about the Earth at various altitudes and pose the risk of striking satellites.

“We track every object in space” now, Hyten said, urging “international norms of behavior in space.”

He added, “We have to deter bad behavior on space. We have to deter war in space. It’s bad for everybody. We could trash that forever.”

But now rivals like China and Russia are building weapons to deploy in the lower levels of space. “How do we prevent this? It’s bigger than a space problem,” he said.

Deterring conflict in the cyber, nuclear and space realms is the strategic deterrence goal of the 21st century, Hyten said.

“The best way to prevent war is to be prepared for war,” he said.

Hyten believes the U.S. needs a fundamentally different debate about deterrence. And it all starts with nuclear weapons.

“In my deepest heart, I wish I didn’t have to worry about nuclear weapons,” he said. Hyten described his job as “pretty sobering, it’s not easy.”

But he also noted the mass violence of the world prior to 1945 when the first atomic bomb was used. Roughly 80 million people died from 1939 to 1945 during World War II. Consider that in the 10-plus years of the Vietnam War, 58,000 Americans were killed. That’s equivalent to two days of deaths in WWII, he said.

In a world without nuclear weapons, a rise in conventional warfare would produce great numbers of mass casualties, Hyten said. About war, he said, “Once you see it up close, no human will ever want to experience it.”

Though America has “crazy enemies” right now, in many ways the world is more safe than during WWII, Hyten said. The irony is that nuclear weapons deterrence has kept us from the type of mass killings known in events like WWII. But the U.S. must know how to use its nuclear deterrence effectively.

Looking ahead, Hyten said the U.S. needs to think about space as a potential war environment. An attack in space might not mean a response in space, but on the Earth.

Hyten describes space as the domain that people look up at it and still dream about. “I love to look at the stars,” but said he wants to make sure he’s not looking up at junk orbiting in the atmosphere.

‘Space geek’

Hyten has served in the Air Force for 35 years. He originally wanted to be an astronaut, but his eyesight was too bad. He got a waiver, and graduated Harvard in 1981 with an engineering degree on a ROTC scholarship. He entered the Air Force thinking he would only do four years. But then he had a close-up view of what a young Air Force officer could find in the last frontier of space as satellites and military space science were booming.

“God, I love space,” he said.

In introducing Hyten, Amy Zegart, co-director of CISAC, described him as a person of unwavering dedication and profound insights who understands the gravity of situations. “A self-described space geek,” she said.

Hyten lauded CISAC for its research and educational work on national security, and said he enjoyed being around people willing to test out new ideas and discuss potential solutions for vexing problems.

Earlier in the day on campus, Hyten met with William J. Perry, a former U.S. Secretary of Defense and senior fellow at CISAC; George Shultz, a former U.S. Secretary of Defense and senior fellow at the Hoover Institution; and Condoleezza Rice, a senior fellow at the Freeman Spogli Institute for International Studies and Hoover Institution.

General Hyten was nominated for reassignment to head the U.S. Strategic Command on Sept. 8, 2016. He commanded Air Force Space Command from 2014 to 2016.

The Trump administration’s reinstatement of a policy that bans U.S. foreign aid to agencies that provide abortion counseling abroad was a predictable move that could have unintended consequences, Stanford researchers say.

The move freezes funding to nongovernmental organizations that provide abortion services or discuss abortions as a legitimate  family-planning option. It revives what is known as the “Mexico City Policy,” so called because it was announced by President Regan in 1984 during a U.N. population conference in Mexico City. It’s a highly partisan policy, which has been implemented under Republican administrations and suspended by Democratic presidents.

From that standpoint, the move to revive the policy was no surprise, said Grant Miller, PhD, an associate professor of medicine at Stanford and core faculty member at Stanford Health Policy. But Miller’s research has shown that the policy actually appears to have the unintended effect of increasing, not decreasing, abortions in the developing world.

“The bottom line is that it doesn’t matter what you think about abortion and the morality and ethics of it,” Miller told me. “I don’t think either side of the disagreement would think a good policy is one that leads to an increase in abortions. Neither side wants to see more abortions.”

In 2011, Miller published a study with Eran Bendavid, MD, on the impact of the policy between 1994 and 2008 in sub-Saharan Africa, a region in which family planning services are heavily financed by U.S. foreign aid. Family planning agencies provide a range of family planning services, including contraception, so when their funding is cut, the availability of contraception declines, said Bendavid, the study’s lead author and another faculty member at Stanford Health Policy. This results in declining use of safe contraception and an increase in abortion rates, the researchers found.

“Sure enough, where you see this relative decline in use of contraception is where you see this uptick in abortion,” said Bendavid, an assistant professor of medicine. “Our theory of what is underlying this is this notion that when women have more restricted access to modern contraception, they rely on abortion. If the intention was to curb abortion, then what we observe is that cutting support to family planning organizations led to the  opposite effect.”

Miller followed that up with another study published in 2016 that focused on Nepal during the period when the government legalized abortion, making it more widely available. The policy change gave him the opportunity to test the idea of abortion and contraception as substitutes — i.e. that use of one method to limit family size reduces use of the other. In fact, as the number of abortions rose, use of contraception declined, he found.

“What is remarkable is that this is clear evidence on this interchangeable use that women make in use of contraceptives and abortion services,” Miller said.

In other words, women are trying to control the number of children they have and will use one or the other, depending in part upon what is most available. “If contraception is available, they won’t have to resort to abortion,” Bendavid said.

He said these results have subsequently been corroborated in other studies in sub-Saharan Africa.

"One mistake was to discount Russia’s importance in international affairs. The U.S. became engrossed in wars in Iraq and Afghanistan, thinking that Russia was weak, and generally unimportant. Under President George W. Bush, the U.S. assumed that the world was unipolar after the Cold War, and that it would always be so," writes Kathryn Stoner, a senior fellow at the Freeman Spogli Institute for International Studies and faculty director of the Ford Dorsey Program on International Policy Studies at Stanford for the New York Times "Room for Debate".

Why is terrorism such a vexing problem for policy makers to solve?

The details – and not sloganeering – are important in grappling with the terrorist threat against the U.S. and West, a Stanford scholar suggests. One reason is that the study of terrorism is often confused and contentious, and the study of counterterrorism can be even more frustrating, says Martha Crenshaw, a Stanford terrorism expert and senior fellow at the Center for International Security and Cooperation.

“The conceptual and empirical requirements of defining, classifying, explaining, and responding to terrorist attacks are more complex than is usually acknowledged by politicians and academics, which complicates the task of crafting effective counterterrorism policy,” wrote Crenshaw in a new book, Countering Terrorism, with her co-author Gary LaFree, a criminal justice professor at the University of Maryland.

The researchers examined about 157,000 terrorist attacks that have occurred around the world since 1970. These are catalogued in the Global Terrorism Database at the University of Maryland. Crenshaw founded the Mapping Militant Organizations project at Stanford to identify militant organizations globally and trace how they arise, their root causes and their connections. Understanding the nature of terrorism, the diverse groups and ever-changing aspect of how they adapt is a key theme in her research.

Crenshaw said the stakes in fighting terrorism today are especially high since the consequences of missteps and miscalculations can be catastrophic. While research in what is now known as terrorism studies has made significant strides, more progress is needed on the analytical and academic fronts.

“Terrorist attacks are rare, yet they encourage immediate and far-reaching responses that are not easily rolled back. Most attempts actually fail or are foiled, so that examining only successful terrorist attacks gives an incomplete picture,” the scholars wrote.

Obstacles and hindrances

After 9/11, the U.S. reshaped its policies and institutions to deal with terrorism. Fifteen years later, Crenshaw and LaFree analyzed the lessons learned from 9/11 and how governments responded. Both authors are participating in a Jan. 25 panel discussion at Stanford on the subject of their book. Crenshaw and Lafree suggest three key principles emerge from their research. Countries like the U.S. should prepare for change, disruption, and surprise from terrorist groups.

Second, countries should resist the temptation to magnify the image of the destructive power of terrorism as well as the vulnerability of its targets. Finally, the U.S. needs to accept limits to its ability to totally manage and control the jihadist threat. As Crenshaw and LaFree noted, “Even superpowers cannot completely control their environments. Terrorist threats are constantly evolving, never static.”

A realistic understanding of the actual extent of terrorist capacity to harm national security interests is the best approach, she said. “Governments, especially the American government, should avoid both overreacting and promising or threatening overreaction, which means entertaining modest expectations about what can be accomplished in an extremely complex and uncertain threat environment that requires constant adaptation and adjustment,” they wrote.

Counterterrorism policy should be reasonable, practical, and balanced – in a word, sensible, Crenshaw said.

“There is no perfect solution,” she and LaFree said.

The top priority of the U.S. government is to prevent attacks on American soil, she said. While this is a clear goal, no one in political leadership can guarantee the public absolute security. “If the goal is set as the complete absence of terrorist attacks, then policymakers become so anxious that a terrorist will slip through the preventive security net that they risk panic or overreaction. Fear of being blamed in the aftermath of an attack starts to take precedence over all other considerations,” they wrote.

Policy paradoxes

Crenshaw and Lafree’s research revealed some policy paradoxes. One involved counterterrorism: policymakers tend to set overly ambitious policies to eradicate terrorism completely, rather than risk being called “reactive” rather than “proactive.” But Crenshaw said such goals lack clarity and realism, and can lead to unwise and unattainable objectives. For example, in the wake of 9/11, the U.S. government believed that overthrowing authoritarian regimes in countries like Afghanistan, Iraq, Syria, Libya and Yemen in favor of “democratic change” would serve as the antidote to terrorism.

However, the change did not take place, and the U.S. has since had to intervene militarily to restore or establish security and stability for weak and embattled allies facing terrorism. One aim for American policy should be greater precision about the strategic goals of military action abroad and that connection to security at home, said Crenshaw and LaFree.

“If the contradictions behind the paradox cannot be resolved, policymakers must find a middle ground between the tactical and strategic,” they wrote.

Another problem is measuring progress against terrorism, Crenshaw and LaFree said. Significant skepticism exists about what the metrics mean in regard to drone strikes, bombs dropped, targets struck, arrests made and cases prosecuted, convictions secured, territory seized or regained, plots foiled, websites taken down, Facebook postings and Twitter accounts deleted, and so on.

“Are these measures of success against terrorism or measures of the extent of the government’s efforts? These metrics calculate what government has done, not necessarily the effect of its actions on adversaries’ calculations and capabilities,” the researchers said, adding that government measures may be taken before a specific adversary exists.

Finally, the real agents behind terrorism are extremely difficult to identify, Crenshaw and LaFree said, because there is no standard “terrorist organization,” and groups evolve, mutate and adapt. Meanwhile, governments and researchers often struggle to establish responsibility for specific attacks.

This paper investigates the impact of human barriers on international trade using data on common ancestry. Using data on 172 countries covering the near universe of international trade, our analysis documents that country pairs with a large ancestral distance are less likely to trade with each other (extensive margin) and, if they do trade, they trade fewer goods (intensive margin). The results are robust to including a vast array of micro-geographic and political control variables. We explore the role of several proximate determinants that lead to this negative relationship, including differences in values, preferences, technology, as well as migration patterns. Our findings offer a partial explanation to the distance puzzle, the observation that estimates of geographic distance have remained persistently high despite substantial decreases in transportation costs in recent years.

Abstract:

In Revolution and Rebellion in the Early Modern World, I showed that turning points in global population trends have been driving waves of political stability or crisis for at least the last 500 years. We are currently seeing a new turning point, as rich countries enter a period of workforce decline and emerging markets divide into those with falling fertility vs. stable and still-high fertility. Drawing on experience from previous centuries in Europe and Asia, we can forecast political trends; these include a new wave of revolutions in Africa and the Middle East and a surge in populist and protectionist politics in Europe and the U.S., but also eventual peaceful transitions to democracy in Russia and China.

Temperature data are commonly used to estimate the sensitivity of many societally relevant outcomes, including crop yields, mortality, and economic output, to ongoing climate changes. In many tropical regions, however, temperature measures are often very sparse and unreliable, limiting our ability to understand climate change impacts. Here we evaluate satellite measures of near-surface temperature (Ts) as an alternative to traditional air temperatures (Ta) from weather stations, and in particular their ability to replace Ta in econometric estimation of climate response functions. We show that for maize yields in Africa and the United States, and for economic output in the United States, regressions that use Ts produce very similar results to those using Ta, despite the fact that daily correlation between the two temperature measures is often low. Moreover, for regions such as Africa with poor station coverage, we find that models with Ts outperform models with Ta, as measured by both R 2 values and out-of-sample prediction error. The results indicate that Ts can be used to study climate impacts in areas with limited station data, and should enable faster progress in assessing risks and adaptation needs in these regions.

Improving the U.S.-China relationship is a focus at the Center for International Security and Cooperation.

CISAC continued this tradition in co-sponsoring the 8th Sino-U.S. Security Relations and Cooperation Conference in Beijing from Dec. 14-15, 2016. The conference was hosted and co-sponsored by the Foreign Ministry's China Institute of International Studies (CIIS).

Ambassador Su Ge, president of CIIS, attended the conference and delivered an opening remark. FSI’s Thomas Fingar and Teng Jianqun from CIIS chaired the conference.

Fingar said, “Although held at a time of uncertainty about the future of U.S.-China relations, the conference included constructive exchanges on strategic stability, obstacles to cooperation in space, and other sensitive topics.”

He added, “The exchanges were frank and constructive because they built on the foundation of understanding and trust developed through years-long exchanges between CISAC and CIIS. In the next phase, small teams of American and Chinese experts will develop joint blueprints to enhance understanding of issues critical for nuclear stability and space cooperation.”

CISAC co-founder John W. Lewis has been active for many years encouraging and supporting better ties between the U.S. and China. He is an expert on Chinese politics, U.S.-China relations, China's nuclear weapons program, U.S. policy toward Korea and health security issues in northeast Asia.

During this most recent Beijing conference, scholars and security experts from both the U.S. and China held in-depth discussions on topics including cybersecurity, outer space cooperation, maritime dispute management, missile defense, grey zone cooperation, and China-U.S. nuclear issues.

The American attendees included scholars from CISAC (Fingar, Brad Roberts, and Joseph Torigian); Brad Roberts, director, Center for Global Security Research, Lawrence Livermore National Laboratory; Major General Roger W. Burg, former commander, 20th Air Force; Vice Admiral Michael Connor (retired), U.S. Navy; Lieutenant General Susan J. Helms (retired), U.S. Air Force general and former NASA astronaut; Lieutenant General James M. Kowalski (retired), U.S. Air Force general; Steven M. Benner,chief, Strategy and Campaign Division, U.S. Strategic Command, among others.

The Chinese experts came from a variety of institutions – CIIS, China Academy of Engineering Physics, the People’s Liberation Army (PLA) Rocket Force, Rocket Force College, China Defense Science and Technology Information Center, PLA Navy Academy of Military Science, PLA South Command, Chinese Academy of Social Science, Renmin University of China, National Defense University, Tsinghua University, etc.

Siegfried Hecker wrote the following op-ed for the Jan. 12 edition of The New York Times:

Since my first visit to North Korea’s Yongbyon nuclear complex in 2004, I have witnessed the country’s nuclear weapons program grow from a handful of primitive bombs to a formidable nuclear arsenal that represents one of America’s greatest security threats. After decades of broken policies toward Pyongyang, talking to the North Koreans is the best option for the Trump administration at this late date to limit the growing threat.

North Korea broke out to build the bomb because President George W. Bush was determined to kill President Bill Clinton’s 1994 “Agreed Framework,” a bilateral agreement with the North to freeze and eventually dismantle the North’s nuclear program. Hard-liners in the Bush administration viewed it as appeasement. Mr. Bush labeled the North, along with Iran and Iraq, part of an “axis of evil” in January 2002.

At the first bilateral meeting with Kim Jong-il’s regime in Pyongyang in October 2002, Bush administration officials accused North Korea of violating the Clinton pact by clandestinely pursuing the uranium path to the bomb. Washington had already detected this effort in the late 1990s, but it was deemed an insufficient threat not worthy of jeopardizing the gains made by the plutonium freeze.

For the Bush administration, the clandestine uranium effort was all it needed to walk away from the Agreed Framework. Yet Mr. Bush’s team proved unprepared for the consequences and stood by as North Korea resumed its plutonium program and built the bomb.

During six visits between 2004 and 2009, I watched the North continue to try to engage Washington, while the Bush administration preferred the six-party talks led by China, believing that the North would have greater difficulty cheating in the context of multilateral diplomacy. In a 2004 visit, I was even allowed to hold a piece of plutonium — in a sealed glass jar — to convince me and Washington that North Korea had the bomb.

In September 2005, China orchestrated a six-party joint statement calling for a nuclear-weapon-free Korean Peninsula. When the Bush administration concurrently slapped financial sanctions on Pyongyang, the North Koreans walked out of the six-party talks and responded with their first nuclear test in October 2006.

I was in Pyongyang three weeks later and found that although the test was only partly successful, it marked a turning point in the North’s nuclear program. North Korea became a nuclear weapon state and insisted that all future negotiations proceed from that reality. Mr. Bush left office with the North most likely possessing up to five plutonium-fueled nuclear weapons and an expanding uranium program.

North Korea greeted the Obama administration with a long-range rocket launch, followed by a second nuclear test in May 2009 — this one, successful. Unlike the Bush administration, which faced the prospect of the North’s violating the Nuclear Nonproliferation Treaty, the Obama administration faced the North’s steady march to an expanding arsenal.

Mr. Obama was also unwilling to engage directly with Pyongyang, insisting instead that the North denuclearize before starting talks. It appears the Obama administration also viewed the regimes of Kim Jong-il and his son and successor, Kim Jong-un, as repugnant and hoped for their collapse, while also staying in step with two conservative South Korean administrations. Mr. Obama’s preferred path has been to tighten United Nations and United States sanctions and to pressure Beijing to rein in Pyongyang. Neither strategy has stopped the Kim regime from expanding its nuclear program.

Pyongyang upped the ante on its nuclear program with a remarkable revelation during my seventh and last visit in November 2010: the existence of a modern uranium centrifuge facility in Yongbyon. That facility served notice that the North was now capable of pursuing the second path to the bomb. No outsiders are known to have been in Yongbyon since my 2010 visit.

Satellite imagery of the Yongbyon complex combined with official North Korean propaganda photos and three additional successful nuclear tests point to a robust and rapidly expanding nuclear arsenal. My best estimate, admittedly highly uncertain, is that North Korea has sufficient plutonium and highly enriched uranium to build 20 to 25 nuclear weapons.

The North also launched some two dozen missiles in 2016, including partly successful road-mobile and submarine-based missiles that could potentially carry nuclear warheads.

President-elect Donald J. Trump faces a much graver threat from the North than his two predecessors. Pyongyang can most likely already reach all of South Korea, Japan and possibly even some United States targets in the Pacific.

The crisis is here. The nuclear clock keeps ticking. Every six to seven weeks North Korea may be able to add another nuclear weapon to its arsenal. All in the hands of Kim Jong-un, a young leader about whom we know little, and a military about which we know less. Both are potentially prone to overconfidence and miscalculations.

These sensitive nuclear issues require focused discussions in a small, closed setting. This cannot be achieved at a multilateral negotiating table, such as the six-party talks.

Mr. Trump should send a presidential envoy to North Korea. Talking is not a reward or a concession to Pyongyang and should not be construed as signaling acceptance of a nuclear-armed North Korea. Talking is a necessary step to re-establishing critical links of communication to avoid a nuclear catastrophe.

Mr. Trump has little to lose by talking. He can risk the domestic political downside of appearing to appease the North. He would most likely get China’s support, which is crucial because Beijing prefers talking to more sanctions. He would also probably get support for bilateral talks from Seoul, Tokyo and Moscow.

By talking, and especially by listening, the Trump administration may learn more about the North’s security concerns. It would allow Washington to signal the strength of its resolve to protect its allies and express its concerns about human rights abuses, as well as to demonstrate its openness to pragmatic, balanced progress.

Talking will help inform a better negotiating strategy that may eventually convince the young leader that his country and his regime are better off without nuclear weapons.
