The Credibility Myth

One of the most frequent critiques leveled at President Obama is that he has diminished the United States’ international “credibility.”  For example, former Secretary of Defense Chuck Hagel has argued that Obama’s decision not to bomb Syria after the use of chemical weapons there in 2013 damaged U.S. credibility.  These critics argue that the United States must follow through on its commitments today so that its threats will be credible (and thus effective) tomorrow.

I have a new article published today at War on the Rocks explaining why these arguments about America’s credibility and reputation are misguided.  You can read the article here.

One Year of On Security; the Paris Climate Agreement Moves Forward

It has come to my attention that On Security is officially one year old this week. To celebrate, I’m throwing a party and you’re all invited! Just kidding. Instead, I thought I would shift gears a little bit and revisit one of my favorite posts from last year.

In this post from last December I discussed the Paris Climate Talks. I wrote about the basic goals of the conference (minimizing the rise in Earth’s temperature by limiting or reducing greenhouse gas emissions) and offered three explanations from international relations theory for why climate change is a uniquely difficult challenge for states to tackle. Although 180 countries have since signed the agreement that came out of the Paris talks, at the start of this month only 23 countries had ratified the agreement. (At least 55 states must ratify the agreement for it to go into effect.)

The good news is that last week the United States and China announced that they would be ratifying the Paris agreement.  Together, the United States and China account for nearly 40% of total world emissions, so it is hoped that their commitment to reducing emissions under the terms of the Paris agreement will both have a real impact on global temperatures and encourage other states to ratify the agreement.

The announcement raises some interesting issues related to U.S. domestic politics. In the United States, the Executive signs treaties but the Senate must ratify them. Sometimes this results in treaties that are signed but never ratified, like the Kyoto Protocol. In this case, President Obama has chosen to issue an executive order to ratify the Paris agreement, bypassing the need for Senate approval. Obama has turned to this policy tool frequently throughout his presidency.   Executive orders and agreements do not necessarily outlast the sitting president—although Hillary Clinton has voiced her support for the Paris agreement, Donald Trump has indicated that he would withdraw U.S. support if elected. To the many challenges hampering efforts to mitigate climate change, we must add the challenges of domestic politics.

America’s Reputation: Syria and Ukraine

I am currently working on an article about the role of reputation in international politics—that is, how a state’s reputation for action (or inaction) affects its ability to get what it wants from other states. We are often told that the United States must act in a certain situation to preserve its “credibility” for future crises. The Vietnam War was frequently justified along these grounds: if the United States did not uphold its commitment to South Vietnam, then the Soviet Union would not take its threats and promises seriously in other cases. More recently, President Obama was criticized for not taking action against Syria after chemical weapons were used against civilians in the summer of 2013. Critics argued that the failure to take action against the Assad regime emboldened Putin to invade Ukraine. According to Marc Thiessen, “Putin believes there will be no real costs for his intervention in Ukraine because there were no costs in Syria.”  My work on compellent threats demonstrates that reputation does not actually operate in this way, and I hope to be able to point you to the finished article soon.

In the meantime, however, I can point you to a fascinating article on this topic that ran in The Atlantic in March. One of the biggest challenges we face when studying the use of threats in international politics is assessing why a particular threat works (or doesn’t) to influence a state’s behavior. This is especially tricky in the case of deterrence, in which one state issues a threat to persuade an adversary not to undertake a particular course of action. How can we tell that the threat has worked? If we observe that the adversary chooses not to undertake the proscribed action, that could mean that the threat was effective in influencing the target’s behavior—or it could mean that the target never intended to take the prohibited action in the first place, and thus the threat didn’t actually change the target’s behavior. To be really sure that the threat had influenced the target, we would want to know exactly how the decision makers in the target state assessed the threat and whether it caused them to change their state’s policies as a result. We might want to interview the targeted leader, for example, but it is likely to be nearly impossible for a researcher to get such access. Even if we could interview the targeted leader, she may have strong incentives not to admit that a threat influenced the state’s behavior—otherwise she may look weak to her political rivals and to regional adversaries. We might be able to rely on documents or memoirs published long after a particular crisis has passed, but this doesn’t help us much in the short term (and nor can we be certain that memoirs are accurate or that we have access to all the relevant documents).

In other words, it is extremely difficult to determine whether and to what extent a threat influences another state’s behavior. Often we must settle for observing a state’s behavior as an imperfect measure of threat effectiveness. To get back to that article I mentioned: Julia Ioffe interviewed several individuals with access to Vladimir Putin about how he interpreted the United States’ decision not to take action against the Assad regime in 2013. She asked whether Obama’s decision not to use force after the chemical weapons attack encouraged Putin to invade Ukraine. The overwhelming response: absolutely not. “No one sees Obama as a weak president, and no one saw that moment as a moment of weakness” according to Igor Korotchenko. “You shouldn’t think of Putin as such a primitive guy. It’s totally clear that the Syrian and Ukrainian crises had nothing to do with one another,” said Fyodor Lukyanov.

This article provides rare and fascinating insight into the mind of one of the United States’ adversaries. No, it is not an interview with Putin himself, but it is about as close as we can get under the circumstances. The view from Moscow is that the United States’ inaction in Syria in 2013 had absolutely nothing to do with the decision to invade Ukraine and that bombing Syria would not have convinced Putin to refrain from acting. Arguments about reputation and credibility have some intuitive appeal, but they do not stand up to scrutiny.

Great Power Status and Nuclear Weapons: The UK Case

In her first major parliamentary appearance since assuming the role of British Prime Minister, Theresa May recently won a vote to renew Britain’s commitment to nuclear weapons.  The British parliament voted on July 18 to replace Britain’s aging fleet of nuclear-equipped submarines, and this vote is being viewed as an effort to cement the United Kingdom’s status as a major player in international politics in the wake of the recent vote to exit the European Union. May asserted that it was time for the UK to be “stepping up” to meet its responsibilities to NATO and to meet threats to Britain’s security head-on. Given the possibility of increased nuclear threats in the future, “it would be an act of gross irresponsibility to lose the ability to meet such threats by discarding the ultimate insurance against those risks in the future.” The vote to renew the submarine program also highlighted strains within the UK. The Trident force is based in Scotland, but the Scottish population widely opposes the nuclear program and has threatened to hold another referendum on independence in the wake of the Brexit vote. It is not clear where the Trident force would go if the Scots do vote for independence.

 
The Trident submarines have been Britain’s only nuclear weapons force since 1998, and one is always at sea ready to launch a weapon if necessary. The nuclear-equipped submarine fleet is considered the ultimate nuclear deterrent: capable of staying at sea continuously, they are nearly impossible to detect and track and thus they grant near perfect certainty that one would be able to retaliate against a nuclear attack on one’s homeland. One of May’s first acts as Prime Minister would have been to write a letter outlining the conditions under which the commanders of Trident submarines on patrol would be authorized to retaliate with nuclear weapons in the event of a nuclear attack on the United Kingdom that rendered the British government unable to make the decision. Every new Prime Minister writes such a letter and it is destroyed when the individual leaves office.

Does the possession of nuclear weapons signify great power status? Maybe it did at one time—back in the Cold War when the US, UK, France, China and Soviet Union were the only states that possessed these weapons. Now, India, Pakistan, North Korea and Israel also wield these weapons without obvious great-power status. As Ian Jack points out, the UK is largely dependent on help from the United States to construct its Trident submarine force. Why could the UK not simply rely on its American ally to provide a nuclear deterrent, especially given the high cost of building and maintaining this program? Does Britain truly view these weapons as necessary for its survival, or is it about clinging to the United Kingdom’s status as a major player on the international stage? In other words, in the twenty-first century, do nuclear weapons serve any useful strategic purpose or do they function mainly as symbols?

 

NATO Deterrence in the Baltics

Donald Trump made headlines earlier this week when he called into question the United States’ obligation to defend its NATO allies in the event of a Russian attack. Article Five of the North Atlantic Treaty states that an attack on one member of the alliance would be considered an attack on all and requires the signatories to assist an ally that is the victim of such an attack. [1] Trump was asked about how the United States should respond if Russia attacks one of its Baltic neighbors, and he said that he would decide whether or not to assist the victim based on whether the state has “fulfilled their obligations to us.” Estonia’s president quickly took to Twitter to defend his country’s contributions, noting that Estonia is one of only five NATO countries that meets the goal of spending two percent of GDP on defense.

NATO recently announced its plan to station four battalions in the Baltics starting in early 2017 to deter Russian aggression, including an American battalion in Poland. I have a new piece over at the National Interest explaining why this will not work to deter a determined Russia from moving against one of its Baltic neighbors. You can read it here.

[1] No word on what happens if an ally and/or its population provokes a non-member into attacking it…hopefully we won’t have to see that played out in the near future.

Realism on Brexit

I don’t know whether I can add much to the discussion of the historic “Brexit” vote through which the British public opted to leave the European Union. I am most troubled not by the vote itself but by the discourse among my mostly liberal well-educated peers about how this disgraceful action was undertaken by xenophobic and short-sighted voters; perhaps most tone deaf was a Facebook post I saw bemoaning the lost opportunity for British young people to freely work and travel and study and marry abroad as a result of this vote. News flash: the children of the middle and upper classes will always be able to find a way to spend a semester in Florence. Somehow I doubt that the majority of the voting British public saw the issue this way.

Although I do follow British news media—partly for work and partly out of personal interest—and have spent time in the UK in the past couple of years conducting research and visiting family, I’m not qualified to judge whether British society is experiencing an upsurge in racism and anti-foreign sentiment or whether this vote was tied to more concrete economic concerns. I do worry that the commentary about the vote dismisses those who voted to leave the EU in the same way that much of the liberal media in the US dismisses presumptive Republican presidential nominee Donald Trump as a racism-stoking buffoon. I think Trump is tapping into a deep vein of anger and frustration with a globalized economy that has left many Americans behind. (This is not to dismiss the very real problems of racism and sexism in the United States that Trump highlights. Undoubtedly some of Trump’s supporters are drawn to him precisely because of the offensive attitudes he spouts.) But assuming all of Trump’s supporters are narrow-minded racists is very dangerous for the left and for the Democratic party. The Democrats used to be the party of populism, but now they seem to be struggling to identify the grievances of working Americans, let alone respond to them.

The Brexit vote does strike me as an interesting case for theorists of international relations. As someone who adheres mostly to a defensive realist perspective on international politics, I have always been a bit skeptical of the EU. The nature of the organization is to ask states to surrender control over their national policies in exchange for access to a single currency and economic market. In this sense, the EU is a peculiarly anti-democratic organization—particularly for one that lists democracy among the preconditions for membership. (Think of how Greece was punished when its citizens voted—yes, voted, that most democratic of activities—to reject continued austerity measures in the summer of 2015.) Can we imagine if NAFTA had contained a provision that surrendered our national monetary policy to some unelected body also responsible for Canada and Mexico? The idea would be laughable in the American context, yet somehow we are surprised that the UK would opt to retake control over its own immigration and trade policies by voting to leave the EU.  We will see whether this is the first in a series of falling dominoes to exit the union.

 

Cheap Threats Has Arrived

cheap_threats_coverIt’s here! My first book, Cheap Threats: Why the United States Struggles to Coerce Weak States is now available for purchase through Georgetown University Press and Amazon. The book focuses on the following puzzle: The United States has the world’s most powerful military and has demonstrated a willingness to use its military power on many occasions (in fact, the book demonstrates that the United States always follows through on its compellent threats[1]). Why, then, would a small, weak state choose not to comply when the United States threatens it with military force to try to convince it to change its behavior? In other words, when the United States says to a weak state, “admit weapons inspectors to your nuclear facilities or we will bomb you,” why would this state choose to resist?

In Cheap Threats, I draw on game theoretic logic about costly signaling to argue that target states resist compellent threats issued by the United States when these threats are cheap to issue and to execute. I demonstrate that the United States has developed a method of war-fighting that limits the costs (human, financial, and political) of employing military force, and thus the threat to employ force is not a convincing signal that the United States is highly motivated to exact compliance from the targeted state. In other words, targets resist in the face of threats that are relatively cheap to execute because the cheapness of the force does not signal that the United States is highly motivated. A target expects that the United States will carry out the threatened action and then give up as the costs of continuing to coerce the target state become too high.

How can I argue that the use of force is cheap for the country with the world’s most expensive defense establishment?  Cheap Threats demonstrates that the United States now has a model of warfare that relies on an all-volunteer military (no politically costly conscripts to send overseas) supplemented by private contractors who rely on advanced technology to attack targets from a distance (precision air power and drones, for example), and that we pay for our wars (Iraq and Afghanistan) with deficit spending. We have effectively insulated the vast majority of the American public from the costs of employing force, and we even shield our own soldiers from many of these costs by opting for “standoff strike” operations like we saw with the 2011 Libya intervention, which was conducted entirely from the skies.[2]

To make the case for my theory, I evaluate an original dataset of compellent threats in all international crises in which the United States was involved from 1945-2007. I also examine in detail four prominent cases in which the United States employed threats to coerce an adversary: the 1962 Cuban Missile Crisis, the 1991 Gulf War, the 2003 War against Iraq, and the 2011 Libya intervention. The Iraq chapters draw on new caches of documents and recordings seized after the 2003 invasion of Iraq to probe Saddam Hussein’s decision making (spoiler alert: he’s not as crazy as you might have thought!), and the Libya chapter traces the course of the U.S. decision to intervene and Qaddafi’s continued resistance. I also take a look at many competing arguments about threat effectiveness. I find, for example, no support for the argument that states determine whether to comply with threats based on the United States’ reputation for acting in past crises. In other words, the United States does not need to take action simply for the purpose of reinforcing a reputation for toughness.

Need more convincing? Read reviews of the book and see a list of contents here.

 

 

[1] A “compellent threat” involves the use of a threat of military force to convince a targeted state to change its current behavior. A “deterrent threat,” on the other hand, is a threat intended to prevent future behavior (nuclear deterrence would fall into this general category).   Cheap Threats focuses only on compellent threats.

[2] The book explains why the costs that the United States incurs when issuing and executing threats, not those incurred by the target, make a threat effective in changing a target’s behavior.

South Korea’s Nuclear Options

In response to North Korea’s recent nuclear test, a debate has reemerged in South Korea about whether the country should deploy nuclear weapons of its own. Last week, Prime Minister Hwang Kyo-ahn declared that the government maintained its official position that South Korea would not possess or develop nuclear weapons. This is not the first time this debate has bubbled up to the surface. In November 2010, when it was revealed that North Korea had built an advanced plant for the production of highly enriched uranium (HEU, which can be used to construct a nuclear weapon), the South Korean defense minister raised the possibility of reintroducing US tactical nuclear weapons.

Some background: South Korea has a sophisticated infrastructure for the production of nuclear energy and cooperates closely with the United States on the development of its nuclear industry. South Korea did pursue a nuclear weapon of its own during the 1970s, but it abandoned the program under pressure from the United States and signed the Treaty on the Nonproliferation of Nuclear Weapons (NPT) in 1975 as a state not permitted to develop nuclear weapons. The United States stationed tactical nuclear weapons in South Korea during the Cold War, but these weapons were withdrawn in 1991, when North and South Korea signed a declaration calling for the denuclearization of the Korean peninsula. You can learn more about the history of South Korea’s nuclear programs from the Nuclear Threat Initiative.

South Korea continues to enjoy a military alliance with the United States that lends it protection under the “nuclear umbrella.” That is, the United States would respond to any nuclear attack on South Korea (presumably, one launched by North Korea) by launching a nuclear strike against the attacker. By this logic of “extended deterrence,” South Korea enjoys the protection of the American nuclear arsenal without having to acquire weapons of its own.

It will be interesting to see whether confidence in the nuclear umbrella begins to erode if and when North Korea develops a missile capable of delivering a nuclear weapon to the United States. Currently, they do not possess such a missile, and the succession of failed tests suggests that they are still a long way from such a capability. If, however, North Korea were in a position to launch a nuclear attack on the United States, then South Korea may start to wonder about the United States’ nuclear guarantee. As long as North Korea cannot hit back after a retaliatory strike by the United States (in response to the North’s nuclear attack on the South), then the United States does not have to fear for its own safety when it launches the retaliatory nuclear strike against North Korea. If, however, North Korea might be capable of launching a nuclear weapon after the United States’ retaliatory strike, then the calculation becomes quite different. South Korea may find itself wondering whether the United States would be willing to sacrifice Los Angeles to respond to an attack on Seoul. In other words, South Korea (and others) may find itself questioning the credibility of the United States’ nuclear deterrent and may start to wonder if it really does need nuclear weapons of its own.

Questions exactly like these arose among the United States’ western European allies during the Cold War, when the United States was similarly pledging to retaliate against a Soviet attack on western Europe (either conventional or nuclear, depending on the time period) with a nuclear attack on the Soviet Union. In fact, doubts about the credibility of the American deterrent helped spur France to pursue its own nuclear weapons program. Hopefully we are still a long way from the day when South Korea will find it necessary to act on similar doubts.

 

Regime Type and Icelandic Feminism

In my research project about decision-making during the Second World War, I am examining how a state’s “regime type,” i.e., the type of government it has (democracy, autocracy, or something in between) affects its foreign policy. I am also examining whether the regime type of a state’s opponent or potential opponent affects foreign policy outcomes. So, for example: does the fact that a potential opponent is a democracy affect a state’s decision to launch a war against it? In the world of international relations, we refer to such theories as “second image” explanations of international political behavior.

In addition to tracking down and interpreting the relevant archival sources on the decisions in question, one of the most challenging aspects of conducting research like this is deciding how to classify a particular state’s regime. Ask yourself this question: how do we determine whether a state is a democracy or not? One obvious answer might be that the state must hold elections. Okay, so….elections for what? For the head of state? For the head of government? What about representatives in the national assembly? What about judges? How many candidates or parties must be running to count as a “real” election? And who is voting? These are just a few of the many criteria that researchers must consider in determining whether we should classify a state as democratic or not. In an earlier post I argued that many of the criteria researchers use to evaluate whether a state qualifies as a democracy are actually measures of how similar a particular state is to the United States, not how well the state measures up to some objective standard.

To me one of the most important criteria for determining whether a state should be counted as democratic is that adults are not excluded from voting in national elections based on their race, gender, or socioeconomic standing. So, for example, it is inappropriate to refer to the United States of 1850 or 1915 as fully democratic because major categories of adults were ineligible to vote (African Americans in 1850 and women in 1915, although we know that African Americans were effectively disenfranchised long after they were officially granted the right to vote, further complicating our assessments).

Back to my research: my project examines the British invasion of Iceland in 1940 (and the planned attack on Norway that was thwarted by Germany’s own invasion of that country). Over the past few weeks I have been researching Iceland’s political system, and I discovered that Icelandic women were granted the right to vote in 1915, before the same right was extended to women in the United States. I also learned that in 1980, Iceland elected Vigdis Finnbogadottir as president, making her the first democratically elected female head of state in the world. A fascinating article by Kirstie Brewer ties this remarkable electoral feat to a day in 1975 when 90% of all women in Iceland went on strike, refusing to attend their jobs outside the home, to perform housework or to look after children in order to call attention to their demands for equal rights with men.  Icelandic fathers dubbed this day “the Long Friday” while they scrambled to entertain children at their workplaces and bought out easy-to-prepare sausages for their kids from the local shops. For many the day was heralded as a wake up call for women demanding equal rights with men.  It’s a fascinating article about the path taken by a state that many have dubbed the most feminist country in the world, and worth thinking about in a U.S. election season where feminism and gender have become major stumbling blocks for the Democratic party.

Special Operations and War on the Cheap

My book Cheap Threats:  Why the United States Struggles to Coerce Weak States is now available for pre-order from Georgetown University Press and Amazon.  In Cheap Threats, I argue that the United States struggles to use threats[1] effectively against weak states (like Iraq, Libya and Haiti) because it has adopted many strategies that render the use of military force relatively cheap.  Because force is cheap, the threat to use force does not convince weak targets of the United States’ compellent threats that the United States is highly motivated.  These targets will resist in the face of a cheap threat–even one issued by the state with the world’s most powerful military–because the cheapness of U.S. military action suggests that the United States lacks the motivation to pursue a long and costly victory against them.  In other words, by making the use of force cheap, we have made threats against weak states less effective.[2] This is a problem because the United States often chooses to launch costly military operations when the threat of force alone is insufficient to change the targeted state’s behavior.

How can I possibly argue that the use of force is cheap for the country that spends nearly as much as the rest of the world combined on defense each year? The first chapter of the book explains in detail the strategies that the United States has adopted to minimize the human, political, and financial costs of employing force—including the use of deficit spending to fund major military operations like the wars in Iraq and Afghanistan. I won’t repeat these arguments here, except to highlight one of the major cost-minimizing strategies that I discuss in the book: the transformation of the American military since the 1970s.

Before 1973, the United States relied on some type of conscription, i.e., compulsory military service, to fight its wars. After the backlash against selective service in the Vietnam War, during which privileged young men were better able to escape the necessity of military service, the United States eliminated conscription and has since relied on an all-volunteer force (AVF). This has led to an increase in education, retention, and professionalization in the service, but the U.S. military is not a representative institution: new recruits are disproportionately drawn from the lower socio-economic classes; the southeastern states tend to be over-represented; minorities are over-represented in the enlisted ranks while whites dominate the officer corps, etc. As a result, the wealthy, educated individuals who are most likely to be members of the decision-making class (members of Congress, scholars at think tanks, i.e., those responsible for making decisions about when and where we fight wars) are insulated from the burdens of military service and increasingly unlikely to have any direct connection to the military themselves. In addition to opting for a volunteer force that shields the vast majority of the American public from the privations and sacrifice of military service, the United States has also relied increasingly on private military contractors to perform functions formerly reserved for the military. The casualties suffered by these individuals are not counted in official figures, which helps to further insulate the general public from the true human toll of America’s military conflicts.

Why does this matter? It matters because strategies that minimize the impact of the use of military force on the American population make it much, much easier for policy-makers to choose to use military force. (Can we imagine that the George W. Bush administration would have been able to sell the war in Iraq if conscription had been in place in 2003?) The AVF makes it much less politically costly to use force, and hence makes it more likely that force will be used. My book demonstrates, however, that such strategies that make the use of force cheaper also undermine our ability to successfully threaten weak states with the use of force.

An op-ed by former Army Captain Matt Gallagher in last Sunday’s New York Times highlights an important and related trend: the growing national obsession with special operations forces (Army Rangers, Delta Force operators, Navy SEALs, etc). “The mythos of Special Operations has seized our nation’s popular imagination, and has proved to be the one prism through which the public will engage with America’s wars…We like our heroes sanitized, perhaps especially in murky times like these.” In the midst of an overall downsizing of the U.S. military, the number of special operations forces continues to rise. Perhaps more importantly, these types of forces conduct their missions in the shadows, with limited Congressional and public oversight of where they are sent (139 countries in 2015, many of these for training missions). Out of sight, out of mind.

As the American public becomes increasingly enchanted with the myth of the commando running secret missions in bad neighborhoods while bathed in the green glow of night vision goggles, it is pushing the United States further down this path of seemingly cheap, low-commitment, sanitized military force. As Cheap Threats argues, however, this will continue to undermine our ability to wield threats of force effectively.

 

 

[1] For example, the United States might threaten a small state with air strikes if it does not admit weapons inspectors.

[2] The theory I advance in the book suggests that threats against more powerful states will be more effective because they are more costly to issue and to execute. See the book for a more thorough explanation.
