Introduction
This essay addresses key readings in international relations (IR) from the perspective of an undergraduate student exploring foundational theories within the discipline. Drawing on my studies in an introductory IR module, I will examine three seminal texts: Kenneth Waltz’s Man, the State, and War (1959), Robert Keohane’s After Hegemony (1984), and Alexander Wendt’s Social Theory of International Politics (1999). For each, I will outline the main point, discuss the insights gained into IR and the reasons behind them, and pose questions that arise, explaining their significance. This structure allows for a reflective analysis that connects theoretical arguments to broader IR debates—such as realism, liberalism, and constructivism—highlighting how these works challenge assumptions about state behavior, cooperation, and identity in an anarchical world. By doing so, the essay demonstrates a sound understanding of IR’s core concepts while critically evaluating their applicability to real-world scenarios, aiming to foster deeper engagement with the field’s limitations and potentials.
Waltz (1959): Levels of Analysis in Explaining War
Waltz argues that wars stem from multiple levels of causation—individual human nature, domestic state structures, and the anarchic international system—yet emphasizes the third image, where systemic anarchy compels states to prioritize self-help and power balancing, rendering peace precarious without overarching authority. This framework critiques simplistic views that attribute conflict solely to aggressive leaders or flawed societies, instead revealing how the absence of global governance inherently fosters insecurity and rivalry, much like how environmental pressures shape animal behavior in nature—pushing states toward defensive postures that inadvertently escalate tensions. Through this, Waltz equips readers to dissect historical conflicts, such as World War I, not as isolated events but as products of systemic dynamics that override individual or national intentions.
The insight I gained from Waltz into IR centers on the structural constraints of anarchy, which illuminated why rationalist approaches often dominate explanations of state actions, because they underscore the inescapable logic of survival in a self-help system—shattering my earlier naive belief in diplomacy as a panacea for global disputes. This perspective proved enlightening during class discussions on the Ukraine crisis, where power imbalances and security dilemmas mirror Waltz’s third image, showing how even well-intentioned actors succumb to systemic pressures; indeed, it forced me to reconsider liberalism’s optimism about institutions, highlighting realism’s pragmatic edge in accounting for persistent conflict. Furthermore, this insight deepened my appreciation for IR’s interdisciplinary roots, drawing from philosophy and history to model human affairs, and explained why theories like his remain foundational despite criticisms of oversimplification.
Yet questions linger about Waltz’s framework, particularly under what conditions domestic factors (second image) might override systemic anarchy to prevent war, and why—because while he acknowledges internal structures like democracy or authoritarianism, he downplays their potential to foster enduring peace, as seen in democratic peace theory, which could refine realism by integrating liberal elements and challenge the inevitability of conflict in multipolar systems. Clarifying this would enhance my understanding of hybrid threats in contemporary IR, such as cyber warfare, where state internals arguably play a larger role than pure anarchy, testing the boundaries of Waltz’s levels and their relevance today.
Keohane (1984): Cooperation in a Post-Hegemonic World
Keohane contends that international cooperation persists beyond hegemonic leadership through regimes—institutionalized norms, rules, and procedures—that reduce transaction costs and facilitate mutual gains among self-interested states, countering realist pessimism by demonstrating how liberal interdependence enables regimes like the World Trade Organization to manage global issues even in anarchy. By blending rational choice theory with historical examples, such as post-World War II economic orders, he humanizes abstract cooperation as a pragmatic response to globalization’s complexities—arguably transforming potential zero-sum games into positive-sum outcomes, where states voluntarily constrain sovereignty for collective benefits, much as partners in a marriage negotiate shared responsibilities to avoid discord.
From Keohane, I derived a crucial insight into IR’s liberal strand, namely that institutions can mitigate anarchy’s harshest effects by fostering reciprocity and information-sharing, which resonated because it explained phenomena like the European Union’s endurance despite Brexit, revealing why cooperation isn’t merely idealistic but strategically viable—thus broadening my view beyond realism’s focus on power to include economic interdependence as a stabilizing force. This was particularly striking when applying it to climate change negotiations, where regimes like the Paris Agreement exemplify Keohane’s logic, illustrating how shared vulnerabilities compel collaboration; typically, such insights encouraged me to question realism’s dominance in IR curricula, appreciating liberalism’s empirical grounding in real-world institutions that arguably prevent systemic collapse.
However, I question whether Keohane adequately addresses power asymmetries within regimes—such as how dominant states like the US might manipulate them for unilateral advantage—and why this matters, because overlooking this could idealize cooperation, ignoring cases like trade wars where weaker actors face coercion, thereby testing liberalism’s assumptions against realist critiques and prompting reflection on reforming regimes for equity in an uneven world. Exploring this inconsistency would refine my grasp of IR’s theoretical debates, especially in analyzing emerging powers like China, where hegemonic transitions challenge post-hegemonic stability.
Wendt (1999): The Social Construction of Anarchy
Wendt posits that anarchy is not an objective condition but a socially constructed one, where state identities and interests emerge from interactions, enabling cultures of anarchy—Hobbesian rivalry, Lockean restraint, or Kantian friendship—to shape international politics beyond material structures. This constructivist approach critiques neorealism’s determinism by emphasizing ideas, norms, and intersubjective meanings, illustrating how shared understandings can transform enmity into alliance, as in the post-Cold War reconfiguration of Europe—essentially arguing that states make their own realities through discourse and practice, rather than being trapped in eternal conflict.
The insight Wendt provided into IR revolves around the malleability of state behavior through social processes, which enlightened me by demonstrating how identities evolve, explaining shifts like NATO’s expansion not as power plays but as ideational realignments—because this perspective dismantled my prior realist-tinged assumptions, revealing IR as a dynamic field influenced by culture and perception, arguably more attuned to modern issues like identity politics in global populism. This gained traction in my studies of soft power, where Wendt’s ideas connect to phenomena such as the Arab Spring, underscoring why constructivism complements other paradigms; generally, it fostered a more nuanced view, encouraging critical reflection on how discourses of “threat” perpetuate conflicts that could otherwise dissolve.
Still, I wonder about the practical mechanisms for shifting from a Hobbesian to a Kantian culture of anarchy—specifically, what role non-state actors like NGOs play, and why this is pertinent—since Wendt focuses on states, potentially underestimating transnational influences in constructing global norms, which could expand constructivism’s scope to address hybrid challenges like misinformation campaigns, thereby questioning its applicability in a digitized, multipolar era and highlighting gaps in bridging theory with policy.
Conclusion
In summarizing, this essay has dissected the main points of Waltz (1959), Keohane (1984), and Wendt (1999), extracting insights into IR’s realist, liberal, and constructivist dimensions—such as structural anarchy’s constraints, institutional cooperation’s potentials, and social constructions of reality—while posing questions that probe their limitations and invite further inquiry. These reflections, drawn from my IR studies, underscore the discipline’s richness in explaining global dynamics, yet also its need for integration across paradigms to tackle contemporary crises like pandemics or great-power rivalries. Ultimately, engaging with these texts equips students to apply IR more realistically, fostering a critical mindset that recognizes theories’ emotional and contextual contingencies, much as real-world events test their durability—implying that ongoing debate remains essential for the field’s evolution.
