Game theory is a set of mathematical tools used to analyze the strategic interaction between decision makers. Proponents of game theory have offered different perspectives about its potential benefits in the study of politics: It is a rigorous apparatus that can offer a solid foundation for the scientific enterprise; it offers predictions that could be tested with statistical analysis; it can account for the essence of unique cases and could be tested with qualitative evidence. Critics of game theory, in political science and international security specifically, argued in the 1990s that it had generated few empirical insights. Two decades later, game-theoretic approaches to international security remain a robust research program, but their prevalence remains limited. It is important to evaluate the potential benefits of game theory and the contributions that it has made to international security, so as to devise appropriate strategies to maximize its empirical purchase. The controlled comparison approach, using qualitative evidence on a medium number of cases, appears especially promising.

How does the English School work as part of Empirical International Relations (IR) theory? The English School depends heavily on historical accounts, and this article makes the case that history and theory should be seen as co-constitutive rather than as separate enterprises. Empirical IR theorists need to think about their own relationship to this question and clarify what “historical sensitivity” means to them. The English School offers both distinctive taxonomies for understanding the structure of international society, and an empirically constructed historical approach to identifying the primary institutions that define international society. If Empirical IR is open to historical-interpretive accounts, then its links to the English School are in part strong, because English School structural accounts would qualify; they are, in other ways, weak because the normative theory part of the English School would not qualify. Lying behind this judgement is a deeper issue: if Empirical IR theory confines itself to regularity-deterministic causal accounts, then there can be no links to English School work. Undertaking English School insights will help open up a wider view of Empirical IR theory.
International agreements on environmental issues are the result of the coordination of states’ foreign policies. To understand the international politics of the environment requires attention to the institutional, social, economic, and cognitive factors that determine foreign policies. Although nearly every foreign policy bears on environmental concerns, the focus is on the policies that states adopt centered on humanity’s relationship to the natural world and ecology. Scholarship on environmental policy and foreign policy has not developed distinctive schools of thought. However, organizing scholarship according to a theoretically grounded typology reveals affinities among various scholarly works: systemic, societal, and state-centric approaches can be grouped according to whether they emphasize power, interests, or cognitive factors. Most studies of environmental foreign policy are oriented toward problem solving—identifying discrete problems in existing institutional arrangements and pointing toward solutions to these problems that do not question the institutions fundamentally. This orientation may not be adequate if crossing planetary boundaries leads to environmental challenges so severe that current institutions cannot cope. Climate change poses just such a challenge, and the rising concentration of greenhouse gases in the atmosphere means a future crisis is predictable. Thus, scholars might be best advised to orient toward critical theory, which seeks feasible alternatives to existing arrangements. The study of foreign policy toward the environment would be most useful in helping scholars and policy makers to identify and surmount barriers to transformational changes that would enable humanity to cope with future environmental crisis.
Ethics and foreign policy have long been considered different arenas, which can only be bridged with great analytical and practical difficulty. However, with the rise of post-positivist approaches to foreign policy, much greater attention has been paid to the way that ethical norms and moral values are embedded within the way states understand their own actions and interests, both enabling and constraining their behavior. Turning to these approaches raises a different question to whether ethics and foreign policy can mix, that of how best to understand, analyze, and critique the role that ethics inevitably play within foreign policy making? What are required are perspectives which, instead of constructing an ethical theory in the abstract and applying it to a concrete situation, start from the ethics of the foreign policy arena itself.
Two ways of looking at ethics are especially useful in this regard: a virtue-ethics approach and a relational-ethics approach. These can be best explored by observing how they work in a particular foreign policy context, such as the highly controversial U.K. decision to join the invasion and occupation of Iraq from 2003. This was a policy where ethics came particularly to the fore in both the decision-making process and its justification. The case study can therefore help show the types of questions virtue and relational ethics ask, the way they work as analytical and critical frameworks, and the problems they raise for the role of ethics in foreign policy. They also point toward important future directions for research in the area.

Enlargement has always been an essential part of the European integration project. However, it was the expansion of the European Union (EU) to include the ten Central and Eastern European Countries (CEECs), Cyprus and Malta, unprecedented in scope and scale, which presented the Union with an opportunity to develop a multifaceted set of instruments and transformed enlargement into one of EU’s most successful policies. The numerous challenges of the accession process, along with the enormity of the historical mission to unify Europe, lent speed to the emergence of the study of EU enlargement as a key research area.
The majority of the early studies investigated the puzzle of the EU’s decision to enlarge with the CEECs, and the costs and benefits of the Eastern expansion. However, the questions about the impact of EU enlargement policy inspired a new research agenda. Studies of the influence of the EU on candidate and potential candidate countries have not only widened the research focus of Europeanization studies (beyond the member states of the Union), but also stimulated and shaped the debates on the scope and effectiveness of EU conditionality.
Conditionality has become a useful concept for analyzing the impact of the EU on domestic politics in enlargement countries. Numerous studies have demonstrated the significance of a credible membership perspective and the clarity of the membership conditions for the success of the EU’s transformative power. Following the completion of the fifth enlargement, the effectiveness of the EU approach towards the Western Balkans and Turkey, as well as the sustainability of the Union’s impact in Central and Eastern Europe and the limitations of post-accession conditionality have attracted a lot of scholarly attention. Research on EU enlargement policy has also shaped the debates on the performance of the European Neighbourhood Policy and the diffusion of the EU’s impact beyond enlargement and neighbouring countries.
The European Union Space Policy (EUSP) is one of the lesser known and, consequently, little understood policies of the European Union (EU). Although the EU added outer space as one of its competences in 2009 with the ratification of the Lisbon Treaty, the EUSP roots go back decades earlier.
Officially at least, there is no EUSP as such, but rather a European Space Policy (ESP). The ESP combines in principle space programs and competences that cut across three levels of governance: the supranational (EU), the international (intergovernmental), and the national. However, since the EU acquired treaty competences on outer space, it is clear that a nascent EUSP has emerged, even if no one yet dares calling it by its name.
Currently, three EU space programs stand out: Galileo, Copernicus, and EGNOS. Galileo is probably the better known and more controversial of the three. Meant to secure European independence from the U.S. global positioning system by putting in orbit a constellation of European satellites, Galileo has been plagued by several problems. One of them was the collapse of the public–private partnership funding scheme in 2006, which nearly killed it. However, instead of marking the end of EUSP, the termination of the public–private partnership served as a catalyst in its favor. Furthermore, research findings indicate that the European Parliament envisioned an EUSP long before the European Commission published its first communication in this regard. This is a surprising yet highly interesting finding because it highlights the fact that in addition to the Commission or the European Court of Justice, the European Parliament is a thus far neglected policy entrepreneur. Overall, the development of the EUSP is an almost ideal case study of European integration by stealth, largely in line with the main principles of two related European integration theories: neofunctionalism and historical institutionalism.
Since EUSP is a relatively new policy, the existing academic literature on this policy is also limited. This has also to do with the degree of public interest in outer space in general. Outer space’s popularity reached its heyday during the Cold War era. Today space, in Europe and in other continents, has to compete harder than ever for public attention and investment. Still, research on European space cooperation is growing, and there are reasons to be optimistic about its future.
Even the most critical observers of the creation of the euro found some nice words on the occasion of its 10th anniversary. And yet it needed only a marginal event like the announcement of the newly elected Greek government that the previously stated public debt ratio was gravely miscalculated to move the euro into a critical crisis zone. Swiftly the attention of private credit markets turned to more member states of the eurozone, only to eventually detect that financial stability of banks did not meet sustainability indicators.
What is often labeled as “eurozone crisis” is better understood by a political-economic forensic analysis that rather speaks of eurozone crises. First, the causes for financial and then sovereign debt crises of Greece, Spain, Portugal, and Ireland (to name only the most prominent) differ fundamentally. They were triggered by the same events but caused by differing factors. Second, it is a crisis of economic governance, and thus an institutional crisis that needs fundamental institutional changes. Third, it is a crisis of political leadership.
The overlapping character as well as the interplay of those three dimensions hampers a proper understanding of the dynamics of the processes that started in 2010. By differentiating between national crisis causes, triggering mechanisms, policy responses, and multi-level crises management, we suggest a comprehensive analytical framework that may guide current as well as future research in the operating of an incomplete currency union.

Evolution, as a biological process and a metaphor, has utility in our understanding of international relations. The former is largely inapplicable for obvious, conceptual, and empirical reasons; but the latter is more promising, though those who use it must be explicit about its limitations. There must be considerations on how evolution contrasts with conscious adaption and imitation, on the argument for the need to distinguish among them analytically and empirically, and on the further exploration of the different conditions in which these other two mechanisms might be relevant.
On the one hand, the idea of a capitalist peace is a set of loosely integrated, but testable propositions. On the other hand it is part of a wider, libertarian philosophy of life. The spirit of this wider conception is best expressed by a quote from a pioneer of quantitative international politics, in 1981 Rummel wrote, “If you want peace, then minimize the power of government.” Although there has been a proliferation of variables assessing capitalism and economic interdependence—from economic freedom via contract intensity to the avoidance of state ownership or protectionism—the most frequently analyzed proposition about the capitalist peace says that trade makes military conflict and war less likely. By and large, the evidence supports this proposition in dyadic designs as well as in monadic designs. This cross-design validity of the proposition is important, because it distinguishes the peace by trade proposition from the democratic peace proposition. Most researchers agree that war is extremely unlikely in dyads where both nations are democracies. But only a minority contends that democracies are less frequently involved in military conflict than other states. The dyadic and the monadic findings are compatible because military conflict looks even more likely between an autocracy and a democracy than between two autocracies. Whereas the democratic peace is limited in application, the pacifying impact of trade or economic interdependence is more general. Moreover, the democratic peace may be embedded in a wider economic or capitalist peace. There is strong evidence that democracy rests on a foundation of capitalism or economic freedom and the prosperity that has been gained only by capitalism or some degree of economic freedom. Moreover, economic freedom and prosperity contribute to the avoidance of civil war. Better still: Economic freedom does not only promote economic growth and prosperity among those nations where people enjoy economic freedom, but the economic freedom of rich countries provides poor countries with the advantages of backwardness and catch-up opportunities.
Capitalist peace theory evolves. It has been suggested that the pacifying impact of trade rests on the expectation that trade, or access to resources and markets, will continue. This suggestion requires a new look at economic sanctions, too. By interfering with trade, sanctions must undermine the expectation of future benefits of trade and globally interconnected markets. Given the rareness of evidence in favor of the effectiveness of economic sanctions in eliminating undesirable policies of other nations, a capitalist peace perspective implies the recommendation to use sanctions much less frequently than politicians do. They are likely to eliminate a pacifying factor when it is most urgently needed.
The wider or visionary perspective on the capitalist peace is useful not only in connecting it with the issue of sanctions, but also in demonstrating the inherent limitations of capitalism as a tool to achieve peace. From a static perspective, capitalism, economic freedom, or trade may exert some pacifying impact, as argued above. But capitalism is a dynamic economic order. It is about “creative destruction”. Capitalism is not egalitarian. Nations grow at different speeds. They rise and decline. Capitalism and unequal economic growth upset pecking orders and contribute to power transitions that are related to risks of war, especially great power war. Whether the contribution of capitalism to power transitions—or its pacifying impact prevails—cannot be judged with much confidence.
The first wave of the International Relations subfield of Foreign Policy Analysis occurred from 1954 to 1994, encompassing a founding period (the 1950s and 1960s) and a period of first consolidation (the 1970s to the end of the Cold War). The early years of the 1950s and 1960s produced some of the defining works that would indelibly shape the character of the field. The work of Richard Snyder, James Rosenau, and Harold and Margaret Sprout molded the field with their focus on decision-making processes, political psychology, cross-national analysis, and actor-specific theory. The subsequent first-wave work, which dealt with small-group dynamics, organizational process, bureaucratic politics, leader personality, cognition and heuristics, culture, domestic political contestation, and national attributes, blended with an understanding of international and regional systemic effects, became FPA classics.
