Since the September 11 terrorist attacks on the United States, terrorism has gained increased prominence in both scholarship and the media. While international terrorist acts are quite visible and highly publicized, such attacks represent only one type of terrorism within the international system. In fact, a very large number of acts of terrorism take place within the context of civil wars. Given the great disparity in power in most civil wars, it is not surprising that terrorism might be seen as a tactic that is often used by insurgent groups, who may have few resources at their disposal to fight a much stronger opponent.
There is a clear linkage between the concepts of terrorism and civil war, yet until recently scholars have largely approached civil war and terrorism separately. Recent literature has attempted to specifically map the intersection of terrorism and civil war, recognizing the extent to which the two overlap. As expected, the findings suggest that civil war and terrorism are highly linked. Other scholars have endeavoured to explain why rebel groups in some civil wars use terrorism, while others do not. Further research focuses on how governments respond to terrorism during civil war or on how the decisions of external actors to intervene in civil wars are affected by the use of terrorism by insurgent groups.
These studies show that there is too little theorizing on the relationship between civil war and terrorism; while scholars are finally considering these concepts collectively, the full nature of their relationship remains unexplored. Additional research is needed to better understand the various ways that terrorism and civil war overlap, interact, and mutually affect other important international and domestic political processes.

Civil war is the dominant form of armed conflict in the contemporary international system, and most severe lethal armed conflicts in the post-Cold War era have been civil/intrastate rather than interstate. Still, it would be misleading to see these conflicts as purely domestic, as many contemporary civil wars such as Syria display clear transnational characteristics, including inspirations from events in other countries, links to actors in other countries, as well as international interventions. Moreover, civil wars often have important implications for other states, including security concerns and economic impacts. There is a need to focus on the growth and core findings in the literature on transnational dimensions of civil war, in particular on how factors outside a particular state can influence the risk of conflict within states as well as some of the central consequences of domestic conflict for other states or relations between states. This line of research has helped expand our understanding of both civil conflict and interstate war, and that a comparative focus on varieties conflict and attention to the possible transnational dimensions of civil war deserve a prominent role in future research.

Civil wars typically have been terminated by a variety of means, including military victories, negotiated settlements and ceasefires, and “draws.” Three very different historical trends in the means by which civil wars have ended can be identified for the post–World War II period. A number of explanations have been developed to account for those trends, some of which focus on international factors and others on national or actor-level variables. Efforts to explain why civil wars end as they do are considered important because one of the most contested issues among political scientists who study civil wars is how “best” to end a civil war if the goal is to achieve a stable peace. Several factors have contributed to this debate, among them conflicting results produced by various studies on this topic as well as different understandings of the concepts war termination, civil war resolution, peace-building, and stable peace.
Theory and evidence about causal mechanisms, at some point (probably) long ago, reached the carrying capacity for integration into knowledge through expression in words alone. Causal mechanisms, through the implementation of systemism in the discipline of international relations, need clarifying. Systemism is used to convey and analyze the contents of a primary source, Causes of War, by Jack Levy and William Thompson. Explaining war is the most long-standing empirical problem, in the sense of Laudan, in the field of international relations. (Laudan suggested, quite helpfully, a shift from empirical content to problem-solving ability for assessing theories with regard to scientific progress.) The diagrammatic approach from systemism is used to translate a narrative from Levy and Thompson into a series of figures that include causal mechanisms from respective areas of theorizing about the causes of war. The overall purpose of this exercise is to show how the approach from systemism possesses the potential to convey causal mechanisms in a way that facilitates scientific progress. All of this augurs well for a visual turn—toward approaches, such as systemism, that can help to more effectively assemble the massive amount of information now available into knowledge about international relations.
Systemism’s essence has been conveyed by its most long-standing exponent, Bunge: a commitment to building comprehensive theories. Systemism transcends reductionism and holism as the other available “coherent views” with respect to operation of a social system. Instead of theorizing at the level of the system (holism) or its components (reductionism), systemism allows for linkages operating at macro- and microlevels, along with back and forth between them. Systemism also includes inputs from, and outputs to, the environment. This comprehensive procedure facilitates the comparison of alternative visions regarding cause and effect. Thus systemism is an approach rather than a substantive theory. One of its distinguishing merits is a capacity to facilitate criticism and comparison of theories through their representation in diagrams that are constructed under a set of rules to convey causal mechanisms.
Understanding the complex set of processes collected under the heading of climate change represents a considerable scientific challenge. But it also raises important challenges for our best moral theories. For instance, in assessing the risks that climate change poses, we face profound questions about how to weigh the respective harms it may inflict on current and future generations, as well as on humans and other species. We also face difficult questions about how to act in conditions of uncertainty, in which at least some of the consequences of climate change—and of various human interventions to adapt to or mitigate it—are difficult to predict fully. Even if we agree that mitigating climate change is morally required, there is room for disagreement about the precise extent to which it ought to be mitigated (insofar as there is room for underlying disagreement about the level of temperature rises that are morally permissible). Finally, once we determine which actions to take to reduce or avoid climate change, we face the normative question of who ought to bear the costs of those actions, as well as the costs associated with any climate change that nevertheless comes to pass.
Climate change emerged in the late 20th century as a topic of global concern and thus a prominent foreign policy issue. Academic scholarship on the international community’s response to the environmental threat was not far behind. Scholars apply a number of theoretical constructs in their search to explain why states behave the way they do in their coordinated approaches to addressing climate-related activities. Of these, systemic theories such as realism, liberalism, and constructivism figure prominently. State-centric theories that consider changing power dynamics in the international system, the importance of evolving coalitions, as well as the role of hegemonic and leadership states, provide contending explanations. Nonstate actors, especially the climate regime itself which has received substantial attention, are similarly considered important variables affecting foreign policy. Constructivist arguments emphasizing the influence of ideas, norms, and identity have become increasingly common, especially as they relate to developmental disparities, “common but differential responsibilities,” and climate justice. While there has been less focus on the role of individual actors, domestic-level variables such as concerns for economic growth, reputation, and capacity to act, as well as multivariable explanations, continue to provide insight. In contrast to the diversity of explanations proposed, the young field is relatively homogeneous in terms of methodological approaches, with qualitative case studies or small-N analyses being most common. If history is a trustworthy guide, however, as on-the-ground, practical approaches to global climate governance evolve, so too will scholarly approaches to its study.
Coalition governments are observed frequently in parliamentary systems. Approximately 70% of all governments in postwar Europe have been one type of coalition or another. Israel has never been ruled by a single-party government in its history. Recently, majoritarian systems like Britain produced coalitions, taking many by surprise.
The prominence of coalitions in parliamentary democracies compels researchers to study them more closely. The Comparative Politics literature investigates, in particular, the dynamics of coalition formation and termination, as well as the domestic policy outputs of coalitions, especially compared to governments ruled by a single party.
Coalitions have generated interest on the International Relations front as well. One avenue of research transcends the “political party” as a building block and conceptualizes coalitions as a “decision unit” by focusing on the group of veto players in a regime’s foreign policy apparatus. Another line of scholarship, situated in the “Democratic Peace” framework, looks at coalitions as a domestic-institutional factor to observe their effects on the likelihood of international conflict.
Departing from the “Democratic Peace” tradition, more recent research in Foreign Policy Analysis rejuvenates the study of coalitions in international politics. This literature not only encourages theory development by scrutinizing why coalitions behave differently than single-parties in the international arena but also bridges the gap between International Relations and Comparative Politics. Emphasizing the organic relationship between domestic politics and foreign policy, foreign policy researchers dissect coalition governments to highlight the role political parties play on foreign policy formulation and implementation. This literature also illustrates the merits of methodological plurality in studying foreign policy. Using a combination of comparative case studies, process tracing, Qualitative Comparative Analysis (QCA) and regression modeling, it sheds light not only on the broader trends that characterize coalition foreign policy but also on the causal mechanisms and contextual factors which often go unaccounted for in purely statistical analyses. The recent advances in role and image theories in Foreign Policy Analysis are expected to influence the study of coalitions and their foreign policies, offering an interpretivist take alongside this positivist trajectory.
Cognitive theory encompasses mental activities such as the observation of different stimuli in an environment; the memorization and recall of information; pattern recognition and problem representation; and complex activities like social judgments, analytic reasoning, and learning. Cognitive psychology also highlights the constraints that prevent individuals from acting as utility-maximizing, fully rational decision-makers. These constraints lead people to rely on a regularly occurring set of cognitive mechanisms to simplify the decision-making process.
Scholars of foreign policy have drawn from several prominent areas of cognitive psychology to inform their research. One such area looks at the beliefs and belief systems that are the building blocks for most judgments. Researchers have also examined how actors use cognitive biases and heuristics to cope with uncertainty, which is abundant in foreign policy settings. An important set of cognitive mechanisms examined in Foreign Policy Analysis (FPA) relates to judgments about policy risks and costs. Factors that facilitate and inhibit learning are crucial for understanding the conditions under which such judgments may improve over time. No cognitive process operates in a vacuum; instead these processes are moderated by an individual’s group context and emotions.
There are several challenges in applying cognitive theory to FPA. Such theories are biased toward populations that are Western, educated, industrialized, rich, and democratic. They are usually first tested using controlled experiments that measure group-level differences; whereas FPA scholars are often interested in the cognitive processes of individual leaders operating in chaotic environments. Individual-level psychological mechanisms may augment or offset one another, as well as interact with variables at the governmental, societal, and international levels of analysis in unpredictable ways. In light of these challenges, FPA scholars who employ cognitive psychology may wish to conceive of their enterprise as a historical science rather than a predictive one.

The member states of the European Union (EU) coordinate, define, and implement foreign policy in the context of the Common Foreign and Security Policy (CFSP). This policy area, often referred to as EU foreign policy, has a broad scope covering all areas of foreign policy and all questions relating to security and defense. The CFSP is supported by a unique institutional framework, in which member states diplomats and officials from the EU institutions jointly make policy. It is led by the High Representative, who is the “face and voice” of EU foreign policy, and supported by the substantial European External Action Service and 140 EU delegations in other countries and international organizations.
Because foreign policy is normally the business of sovereign states, the exceptional nature of the CFSP has long been a subject of inquiry. The CFSP has particularly puzzled advocates of the traditional theories of European integration and international relations, who have failed to appreciate what the EU does in the field of high politics. Given the absence of formal diplomatic recognition and a strong reliance on the resources of the member states, the EU is still not a full-fledged actor, yet it has a strong international presence nonetheless. Its presence and the gradual increase in “actorness” have also raised questions about whether the EU presents a different type of actor, a civilian or normative power, which derives its influence from non-traditional sources of power.
Under the assumption that the EU has some actorness, the Europeanization of foreign policy has become an area of interest. Member states can act through the EU structure to achieve more impact internationally, can adjust national foreign policy on the basis of EU positions, and are socialized into greater European coordination. The relationship between national and EU foreign policy is thus a significant topic of debate. Finally, governance perspectives increasingly provide insight into the organization of the CFSP. How the member states and the EU institutions collectively coordinate, define, and implement EU foreign policy is not only an important question in itself but also matters for policy outcomes.
The European Union’s Common Security and Defence Policy (CSDP) is scarcely two decades old, yet a considerable and diverse body of literature has emerged during this time. CSDP can best be thought of as the functional crisis management end of the Common Foreign and Security Policy (CFSP), of which it is an integral part. It covers both the military and civilian aspects of crisis management, with the majority of overseas missions being civilian in nature. Yet, it is the growth of the military dimension that has spurred extensive debate about the nature of the EU’s actorness and whether it can still be thought of as a civilian power par excellence. Much of the research has been driven by the application of the main theoretical approaches in international relations to CSDP. The result is an extensive, but occasionally cacophonous, body of literature. Given the relative youth of CSDP there are inevitably gaps in the literature, especially the question of how CSDP relates to other policy fields in the external relations of the EU and whether the “D” in CSDP will remain indefinitely silent.
