This study explores logical and empirical implications of friendship and enmity in world politics by linking indirect international relations (e.g., "the enemy of my enemy," "the enemy of my friend") to direct relations ("my friend," "my enemy"). The realist paradigm suggests that states ally against common enemies and thus states sharing common enemies should not fight each other. Nor are states expected to ally with enemies of their allies or with allies of their enemies. Employing social network methodology to measure direct and indirect relations, we find that international interactions over the last 186 years exhibit significant relational imbalances: states that share the same enemies and allies are disproportionately likely to be both allies and enemies at the same time. Our explanation of the causes and consequences of relational imbalances for international conflict/cooperation combines ideas from the realist and the liberal paradigms. "Realist" factors such as the presence of strategic rivalry, opportunism and exploitative tendencies, capability parity, and contiguity increase the likelihood of relational imbalances. On the other hand, factors consistent with the liberal paradigm (e.g., joint democracy, economic interdependence, shared IGO membership) tend to reduce relational imbalances. Finally, we find that the likelihood of conflict increases with the presence of relational imbalances. We explore the theoretical and practical implications of these issues.

The concept of international affinity—albeit under different names—captures a central place in international relations research. This study examines how different types of affinity affect the likelihood of conflict between states. The authors discuss different types of affinities as these appear in the realist and liberal paradigms. They offer a social networks conception of structural affinity—the concept of structural equivalence—which reflects the similarity of international ties across a set of different networks. They test the hypotheses derived from these paradigms, using both existing measures of affinity and their own structural equivalence measures. Their findings suggest that (1) strategic affinity has a consistent dampening effect on the probability of dyadic conflict, (2) trade-related affinity does consistently affect the probability of dyadic conflict, and (3) intergovernmental organization-related affinity has a negative impact on conflict, mostly in the twentieth century.

We propose a model for examining the moderating effect of trust and social support on the relationship between organizational politics and job outcomes. The model was tested empirically using data collected among 142 academics in one of Israel's major research universities. Findings based on interaction effects support the hypothesis that trust and social support are good moderators of the relationship between perceived organizational politics (POPs) and several job outcomes (i.e., job satisfaction, organizational commitment, stress, burnout). In other words, the potentially negative aftermaths of POPs can be controlled and reduced when trust and social support dominate the intra‐organizational climate. Theoretical and practical implications of the findings, as well as recommendations for future studies, are suggested.
