Classical Realism, a pivotal theory in the field of international relations, offers a profound and enduring understanding of global politics. Rooted in the philosophical traditions of Thucydides, Machiavelli, and Hobbes, this theory posits a fundamentally pessimistic view of human nature and state behavior. Its central tenet, as articulated by prominent 20th-century realists like Hans Morgenthau and Reinhold Niebuhr, is that the international system is anarchic, and states, as the primary actors, inherently seek power and security.

This pursuit of power, grounded in the human nature's instinct for survival and dominance, drives state behavior in an international system lacking a central authority. Morgenthau, in his seminal work "Politics Among Nations," argues that states act in their national interest defined in terms of power, a concept he meticulously differentiates from mere material capabilities. His analysis echoes the ancient insights of Thucydides in "The History of the Peloponnesian War," where the Athenian leaders justify their empire and actions through the natural inclination of the strong to dominate the weak. Classical Realism also contends with the role of morality in international politics. While acknowledging moral principles, realists like Morgenthau assert that these principles must be interpreted within the context of the power dynamics and interests of states. This perspective was evident in the Cold War era, where superpowers often justified their actions in moral terms while primarily pursuing their strategic interests.

The theory's emphasis on the balance of power as a stabilizing mechanism in international relations is one of its core contributions. This concept, explored in detail by British historian Edward Hallett Carr in "The Twenty Years' Crisis," explains how states navigate the anarchic international system by aligning and realigning themselves to prevent any single state from achieving overwhelming power. The balance of power mechanism was vividly demonstrated in the European state system during the 19th century, particularly in the aftermath of the Napoleonic Wars, where the Congress of Vienna in 1815 sought to establish a balance to preserve peace in Europe.

In modern geopolitics, Classical Realism's implications are manifold. The rise of China and its implications for the existing international order, the resurgence of Russia under Vladimir Putin, and the United States' response to these challenges are contemporary reflections of realist principles. These situations underscore the persistent relevance of power politics, where states continually assess and act upon their shifting power relations. Moreover, Classical Realism's influence extends to the understanding of contemporary conflicts and alliances. The U.S. foreign policy, for instance, often mirrors realist principles, as seen in its approach to NATO and its pivot to Asia in response to China's growing influence. Similarly, Russia's actions in Ukraine and Syria can be interpreted through a realist lens, emphasizing strategic interests and regional dominance.

Problems of neorealism

Classical Realism vs Neorealism

Classical Realism and Neorealism, while sharing some common ground in the study of international relations, diverge significantly in their theoretical frameworks and interpretations of state behavior. Classical Realism, with its roots in the works of thinkers like Thucydides, Machiavelli, and Hobbes, and later developed by 20th-century theorists such as Hans Morgenthau, particularly in his seminal work "Politics Among Nations," posits that the pursuit of power and the behavior of states in the international arena are primarily driven by human nature, which is inherently power-seeking and selfish. This perspective encompasses a broad array of factors, including moral and ethical dimensions, historical context, and the influence of leadership in shaping state behavior and foreign policy.

Neorealism, or Structural Realism, championed by scholars like Kenneth Waltz, especially in his influential book "Theory of International Politics," shifts the focus from human nature to the structure of the international system. It argues that the anarchic nature of the international system, characterized by the absence of a global government, is what compels states to pursue power. Neorealism particularly emphasizes the distribution of power in the international system (referred to as polarity) and contends that this structural factor is a key determinant of state behavior.

The critique from the Classical Realism camp towards Neorealism centers on several key aspects. Firstly, Classical Realists argue that Neorealism’s approach is overly parsimonious, simplifying the complex dynamics of international relations to a focus on the anarchic structure of the international system and the material capabilities of states. This reductionism, they argue, neglects crucial factors such as the nuances of human nature, the impact of historical events, and the role of individual leadership and diplomatic skills in shaping state behavior. Another point of contention is the accusation that Neorealism is unfalsifiable. Classical Realists contend that Neorealism's broad structural explanations are difficult to test against empirical evidence, which undermines its scientific rigor and explanatory power. They assert that a robust theory of international relations should be able to be empirically evaluated and should account for the complexities and variances observed in state behavior. Additionally, Classical Realists criticize Neorealism for its conceptualization of key concepts like polarity and power. They argue that Neorealism’s understanding of these concepts is inadequate, failing to capture the multifaceted nature of power, which extends beyond mere military and economic capabilities to include elements of soft power, such as cultural influence and diplomatic acumen.

An illustrative example of these theoretical differences can be seen in the analysis of the Cold War. From a Neorealist perspective, the focus would be on the bipolar structure of the international system during this period and how this dictated the behavior of the United States and the Soviet Union. Conversely, a Classical Realist would delve deeper, considering the human decision-making processes, ideological motivations, and historical circumstances that influenced the policies and actions of these superpowers during the Cold War era.

The decline of neorealism

The end of the Cold War marked a significant turning point in the field of international relations, leading to a perceptible shift in the focus and preferences of scholars and theorists. This period saw the decline of Neorealism as the dominant theoretical paradigm, a change that subsequently sparked renewed interest in Classical Realist thinkers. Neorealism, with its emphasis on the bipolar power structure as a defining feature of international relations, found its most compelling application during the Cold War era. The global landscape during this time was predominantly characterized by the rivalry between the two superpowers, the United States and the Soviet Union, a scenario that neatly aligned with Neorealist predictions about the stability of bipolar systems and the balancing behavior of states. Kenneth Waltz, in his pivotal work "Theory of International Politics," articulated this viewpoint effectively, making Neorealism the go-to framework for understanding Cold War dynamics.

However, the unexpected dissolution of the Soviet Union and the subsequent unipolar moment, marked by the United States' unrivaled supremacy, posed significant challenges to the Neorealist framework. The shift in the global power structure and the emergence of new kinds of conflicts and actors that didn't fit neatly into the Neorealist model led to a decline in its explanatory power and appeal. In response to this paradigmatic shift, there was a resurgence of interest in Classical Realism, which offered a more flexible and nuanced understanding of international relations. Classical Realism, with its roots in the thoughts of ancient and Renaissance thinkers and further developed by 20th-century scholars like Hans Morgenthau in "Politics Among Nations," provides a broader analytical lens. It considers a range of factors including human nature, historical context, and the moral and ethical dimensions of state behavior, which appeared more relevant in the post-Cold War era.

The renewed interest in Classical Realism was partly due to its ability to account for the new realities of global politics. These included the rise of non-state actors, increased globalization, and the growing importance of economic and soft power. The Classical Realist view acknowledges the complexity and unpredictability of state behavior and international relations, going beyond the rigid structural framework of Neorealism. Historical examples post-Cold War, such as the rise of China as a global power, the resurgence of Russia under Vladimir Putin, and the United States' responses to these challenges, illustrate the applicability of Classical Realist thought. These events highlight the significance of power politics, national interests, and the role of leadership - all key elements in the Classical Realist tradition.

The decline of Neorealism and the resurgence of interest in Classical Realist thinkers post-Cold War reflect the evolving nature of international relations and the continuous search for theories that effectively explain the complexities of global politics in different historical contexts. Classical Realism, with its emphasis on a broader range of factors influencing state behavior, has regained prominence as a valuable framework for understanding the post-Cold War international order.

Key classical realists

Key classical realists

Thucydides, Machiavelli, Von Clausewitz, and Morgenthau are pivotal figures in the development of Classical Realist thought in international relations, each contributing unique perspectives that have shaped the way we understand the dynamics of power, war, and statecraft.

Thucydides (460–395 BC)

Thucydides, living in ancient Greece from 460 to 395 BC, is indeed recognized as a seminal figure in the development of realist thought in international relations. His most notable work, "The History of the Peloponnesian War," provides a meticulous historical account of the 27-year conflict between Athens and Sparta, two of the most powerful city-states in ancient Greece. Thucydides' analysis goes beyond mere historical narration; it delves into the motivations, strategies, and decisions of the states involved, making it a foundational text in the study of international relations and political power.

A key aspect of Thucydides' work is his focus on the role of power and fear as driving forces in state behavior. He observes how the pursuit of power and the fear of losing it shape the actions of states. This perspective is especially evident in the Melian Dialogue, one of the most cited parts of his work. In this dialogue, representatives from Athens and the small island of Melos debate the nature of power and justice. The Athenians, representing the mightier power, argue that justice is determined by the strong, who have the power to enforce their will. This dialogue encapsulates the realist notion that in international relations, power dynamics often override moral or ethical considerations.

Thucydides' work is praised for its objectivity and lack of bias. Unlike other historians of his time, he sought to provide a factual and analytical account of the war, free from mythological interpretations and divine interventions, which were common elements in the historical writing of that era. His emphasis on rational analysis and empirical evidence has contributed significantly to the development of historical methodology.

His insights into the nature of power, the inevitability of conflict between rising and established powers (often referred to as the Thucydides Trap in modern discussions), and the brutal realities of power politics have had a profound influence on the study of international relations. Thucydides' work laid the groundwork for later realist thinkers, who further explored the themes of power, security, and state behavior in an anarchic international system. His enduring influence demonstrates the relevance of historical analysis in understanding the contemporary dynamics of global politics.

Niccolò Machiavelli (1469–1527)

Niccolò Machiavelli, a prominent figure of the Renaissance period, significantly advanced the realist tradition in political theory with his influential work, "The Prince." Born in 1469 in Florence, Italy, Machiavelli lived through a period of intense political turmoil and change, which profoundly influenced his thoughts and writings. As a diplomat and a political theorist, he had firsthand experience in the complex and often ruthless world of politics, which he distilled into his writings.

"The Prince," written in 1513, is Machiavelli's most famous work and a cornerstone in the study of political science and realist theory. In this book, Machiavelli breaks from the tradition of political idealism and moralistic views of governance that were prevalent in his time. Instead, he adopts a pragmatic approach, focusing on the effective acquisition and maintenance of power by rulers. He famously argues that it is better for a prince to be feared than loved, if he cannot be both, emphasizing the importance of power and control over ethical or moral considerations in ruling.

Machiavelli's concept of "virtù" is central to his philosophy. Virtù, in Machiavellian terms, refers to the qualities of agility, strength, and wisdom that a leader must possess to successfully navigate the unpredictable world of politics. It involves the ability to adapt to changing circumstances, make tough decisions, and, at times, be willing to use deceit and manipulation to maintain power and achieve state objectives.

Alongside virtù, Machiavelli introduces the concept of "fortuna" (luck or chance). He acknowledges that chance plays a significant role in human affairs and that even the most skilled and virtuous leaders are subject to the whims of fortune. However, he suggests that a wise ruler can mitigate the impacts of fortuna through prudent and adaptable leadership.

Machiavelli's insights into power dynamics, statecraft, and leadership have had a lasting impact on the field of political science. His work has been both admired and criticized for its perceived cynicism and ruthless pragmatism. Nonetheless, "The Prince" remains a seminal text in understanding the complexities of political leadership, decision-making, and the art of governance.

His influence extends beyond the realm of political theory into the broader realm of realist thought in international relations. Machiavelli's ideas about power, strategy, and the nature of political leadership resonate with key themes in realism, particularly the emphasis on practical considerations over ideological or moral imperatives in the conduct of state affairs. In the world of international relations, where states are constantly navigating a complex and often unpredictable landscape, Machiavelli's observations about power and leadership continue to offer valuable insights.

Carl Von Clausewitz (1780–1831)

Carl Von Clausewitz, a Prussian general and military theorist, made enduring contributions to the understanding of war and its role in international relations. Born in 1780, Clausewitz's experiences in the Napoleonic Wars profoundly influenced his perspectives on military conflict and strategy. His magnum opus, "On War," written in the early 19th century but published posthumously in 1832, remains a foundational text in military theory and has significantly impacted the field of international relations, especially realist thought.

The central thesis of "On War" is encapsulated in the oft-quoted line, "War is the continuation of politics by other means." This statement highlights Clausewitz's view of war not as an isolated event but as an instrument of state policy, deeply intertwined with political objectives. This perspective shifted the understanding of war from a mere act of aggression or defense to a strategic tool used to achieve political ends. It aligns with the realist notion that states operate in an anarchic international system and must often resort to military force to secure their interests and balance against threats.

Clausewitz's concept of the "fog of war" refers to the uncertainty and chaos that pervade military operations. He argues that war is inherently unpredictable due to factors like incomplete information, the enemy's unforeseen actions, and the limits of human control in complex situations. This idea has profound implications for military planning and decision-making, emphasizing the need for flexibility and adaptability in strategy.

Another significant contribution from Clausewitz is his discussion of the moral and psychological dimensions of war. He recognizes the importance of moral factors, such as public opinion, soldier morale, and the political will of a nation, in the conduct and outcome of war. This holistic approach acknowledges that military success is not solely determined by physical factors like troop numbers or weaponry but also by less tangible elements, including leadership, motivation, and the support of the populace.

The concept of "total war," as explored by Clausewitz, refers to the mobilization of all available resources and the full commitment of a nation's efforts towards the war endeavor. While Clausewitz himself did not use the term "total war," his ideas laid the groundwork for this concept, which became especially relevant in the context of the World Wars in the 20th century.

Clausewitz's insights have had a lasting impact on both military strategy and the study of international relations. In the realm of realism, his ideas resonate with the emphasis on power, security, and the strategic considerations that guide state behavior. "On War" provides a nuanced understanding of the complex interplay between military force and political objectives, offering key insights into the conduct of war and its role in the broader framework of international relations. His work remains essential reading for military strategists, policymakers, and students of international politics, reflecting the enduring relevance of his ideas in understanding the dynamics of conflict and power in the global arena.

Hans Morgenthau (1904–1980)

Hans Morgenthau, a towering figure in the field of international relations, played a pivotal role in establishing the foundations of modern realism. Born in 1904, Morgenthau's intellectual contributions were particularly influential in the mid-20th century, a period marked by the aftermath of World War II and the onset of the Cold War. His seminal work, "Politics Among Nations: The Struggle for Power and Peace," first published in 1948, is regarded as a cornerstone in the development of the realist school of thought.

In "Politics Among Nations," Morgenthau lays out a comprehensive framework for understanding international politics. He posits that the actions of states in the international arena are primarily driven by the pursuit of power, which he views as the central force in international relations. Morgenthau's concept of power is broad, encompassing not just military or economic might but also the influence derived from diplomatic and moral authority.

A key aspect of Morgenthau's theory is the emphasis on the national interest. He argues that the actions of political leaders should be guided by the national interest, defined in terms of power. This perspective echoes the realist belief that states operate in an anarchic international system where survival and security are paramount. Morgenthau's realism, however, is not devoid of ethical considerations. He insists that the pursuit of power and national interest must be tempered by moral principles. This inclusion of a moral dimension marks a significant contribution to realist thought, differentiating Morgenthau's approach from more stringent and amoral interpretations of realism.

Morgenthau also highlights the importance of pragmatic and ethical decision-making in international politics. He argues that a realistic approach to foreign policy involves the careful balancing of power objectives with moral imperatives. This balance, according to Morgenthau, is essential for maintaining international order and preventing conflict.

The influence of Hans Morgenthau extends far beyond his era. His ideas on power, national interest, and the moral dimensions of international politics continue to shape discussions and analyses in the field of international relations. Morgenthau's work provides critical insights into the motivations and behaviors of states, offering a framework for understanding the complex interplay of power, strategy, and ethics in the global political landscape.

Together with thinkers like Thucydides, Machiavelli, and Clausewitz, Morgenthau contributes to a rich and nuanced tradition of realist thought. These thinkers, spanning from ancient times to the modern era, collectively underscore the enduring relevance of power, strategic thinking, and ethical considerations in the conduct of international affairs. Their contributions form the bedrock of realist theory, offering valuable perspectives for understanding the perpetual dynamics of power and conflict in the world of international relations.

Their contibution to classical realism

Together, these thinkers provide a rich and nuanced understanding of the complexities of international relations. Their contributions span centuries, yet their insights remain relevant in today's global political landscape. They collectively underscore the enduring importance of power, strategic thinking, and the ethical considerations that guide state behavior in the international arena.

For over 2500 years, scholars and theorists in the realm of international relations have grappled with the enduring questions of order, justice, and change, each bringing unique perspectives shaped by their historical contexts. This intellectual journey, spanning from the ancient era to modern times, reflects the complexities and evolving nature of global politics.

In the ancient world, Thucydides, in his "History of the Peloponnesian War," provided an early and insightful analysis of the struggle for power and the challenges of maintaining order in the anarchic environment of competing city-states. His narrative underscored the absence of a central authority in international relations and how this vacuum often leads to conflict and a relentless pursuit of power. This theme of order, or the lack thereof, in the international system has been a central concern for realists throughout history, shaping their understanding of state behavior and international dynamics. Centuries later, the Renaissance thinker Niccolò Machiavelli, in his seminal work "The Prince," shifted the focus to the role of leadership and strategy in navigating the treacherous waters of power politics. Machiavelli's pragmatic approach to governance and his emphasis on the importance of adaptability (virtù) and the influence of chance (fortuna) in politics added depth to the discussion of order and power in the international arena.

Moving into the modern era, the writings of Carl Von Clausewitz, especially his masterpiece "On War," expanded the discourse to include the interplay between war and politics. Clausewitz's assertion that "war is the continuation of politics by other means" highlighted the strategic use of military force in achieving political objectives, further underscoring the challenges of maintaining international order in a world where conflict is often inevitable. In the 20th century, the field of international relations saw significant contributions from theorists like E.H. Carr and Hans Morgenthau. Carr, in "The Twenty Years' Crisis," critiqued the idealistic approaches to international politics, advocating for a more realistic understanding of power dynamics. Morgenthau, through his influential book "Politics Among Nations," emphasized the role of national interest, defined in terms of power, in shaping state behavior. He also introduced a moral dimension to realist thought, acknowledging the importance of ethical considerations in the pursuit of national interests.

The question of justice in international relations, intertwined with the pursuit of power, has been a complex and often contentious area of study. While realist theorists primarily focus on power and security, they have not completely disregarded the notion of justice. For instance, Morgenthau's argument for a balance between moral principles and the realities of power politics reflects the tension between idealism and realism in the quest for justice at the international level.

Change, as a constant feature of international relations, has been another area of extensive exploration. The transition from the bipolarity of the Cold War to the unipolar moment post-Cold War, and the current shifts towards a more multipolar world order, illustrate the dynamic nature of international politics. Contemporary theorists like John J. Mearsheimer, with his work on offensive realism in "The Tragedy of Great Power Politics," and Joseph Nye's development of the concept of "soft power," have contributed significantly to our understanding of how shifts in power dynamics, technological advancements, and non-traditional forms of power influence state behavior and the global order.

The study of international relations, through the lenses of order, justice, and change, has been enriched by a myriad of scholars over centuries. Their collective contributions, grounded in different historical contexts and perspectives, offer a comprehensive and nuanced understanding of the complexities of global politics. From Thucydides' ancient insights to the modern analyses of Mearsheimer and Nye, these discussions continue to shape our understanding of the ever-evolving tapestry of international relations.

Structuring their vision

Over the centuries, scholars and theorists in the realm of international relations have indeed tended to advocate a holistic understanding of politics, recognizing the close relationship between domestic and international affairs, acknowledging the role of ethics and community, and often regarding history as cyclical.

A holistic understanding of politics is evident in the way these thinkers incorporate a wide range of factors - including power, strategy, human nature, and ethical considerations - into their analyses. For instance, Hans Morgenthau in "Politics Among Nations" not only discusses power in terms of national interest but also integrates moral dimensions into his realist perspective. Similarly, Carl Von Clausewitz's "On War" delves into the psychological and moral aspects of war, going beyond mere military strategy. The interconnection between domestic and international politics has been a recurring theme in international relations theory. Realist thinkers like E.H. Carr and later Kenneth Waltz in "Theory of International Politics" have shown how internal political dynamics can influence a state’s foreign policy and vice versa. This recognition highlights the complexity of international relations, where domestic issues and international engagements are often intertwined.

The role of ethics and community has also been a significant consideration. While traditional realist thought, as epitomized by figures like Thucydides and Machiavelli, tends to prioritize state interests and power politics, there is an acknowledgment of ethical considerations. Morgenthau, for example, argued for a prudent balance between power pursuits and moral principles. This inclusion of ethics reflects an understanding that international relations are not just about power and survival but also involve moral choices and communal responsibilities.

Regarding history as cyclical is another notable aspect. Many of these theorists observed patterns in history, suggesting that certain dynamics of power, conflict, and cooperation tend to repeat over time. This perspective is rooted in the belief that while the context and players may change, certain fundamental aspects of human nature and state behavior remain consistent. Thucydides’ analysis of the Peloponnesian War, for instance, has been cited as relevant to understanding modern conflicts, illustrating the cyclical nature of history in the context of power struggles and political rivalries.

These dimensions therefore reflect a rich and complex understanding of international relations, encompassing a range of factors that go beyond simplistic or unilateral explanations of state behavior. The contributions of these theorists have provided a comprehensive framework for analyzing the intricate tapestry of global politics, blending practical considerations of power and strategy with ethical, historical, and societal factors.

Domestic and international

Classical realism, as a school of thought in international relations, indeed tends not to draw a stark distinction between domestic politics and the anarchical realm of world politics. This perspective stems from the classical realist view that the same principles governing human nature and behavior underlie both domestic and international politics. Classical realists like Hans Morgenthau, who is often regarded as the father of modern realism with his seminal work "Politics Among Nations," emphasize that the drive for power and survival is a fundamental aspect of human nature. This drive, according to classical realists, manifests itself in the actions of states on the international stage as well as in the behavior of individuals and groups within states. The lack of a central authority (anarchy) in the international system, which forces states to rely on self-help for their security, is paralleled by the competition for power within states.

The blurring of lines between domestic and international politics in classical realism can also be traced back to earlier thinkers like Thucydides and Machiavelli. Thucydides, in his account of the Peloponnesian War, demonstrates how internal political dynamics within Athens and Sparta influenced their foreign policies and the course of the war. Similarly, Machiavelli, in "The Prince," analyzes the behavior of rulers and states in a manner that applies to both domestic governance and foreign policy. This approach contrasts with later theories, like Neorealism, which makes a clearer distinction between domestic and international politics. Neorealism, particularly as developed by Kenneth Waltz in "Theory of International Politics," focuses more on the structure of the international system (anarchy) as the primary determinant of state behavior, treating domestic political factors as secondary. Cassical realism's approach to understanding international relations is grounded in the belief that the principles of power politics are universally applicable, both within and across state boundaries. This perspective acknowledges the interconnectedness of domestic and international political dynamics, viewing them as two sides of the same coin driven by the fundamental nature of human behavior and the quest for power.

Classical realists, in their approach to international relations, indeed recognize the importance of the cohesiveness of communities and shared norms in maintaining order and restraint, both in domestic politics and in international relations. This perspective acknowledges that while power and self-interest are pivotal in state behavior, the role of communal bonds and established norms cannot be overlooked in understanding how order is sustained and how states are restrained from resorting to unrestrained aggression. The classical realist view posits that just as the fabric of a society is held together by shared norms, values, and a sense of community, the international system, despite its anarchical nature, is also influenced by similar factors. These shared norms and values can take various forms, such as diplomatic protocols, international law, and customary practices in state behavior. Even in an anarchic international system, where no central authority exists to enforce rules, these shared norms can exert a significant influence on how states interact with each other.

Hans Morgenthau, a key figure in classical realism, acknowledged the role of moral principles in international politics. He argued that political actions must be tempered by ethical considerations, suggesting that a sense of moral obligation plays a role in the decisions made by states. This perspective implies that the international community, much like a domestic society, is bound not only by power dynamics but also by a shared understanding of certain norms and ethical standards. Similarly, earlier thinkers like Thucydides and Machiavelli, while often focusing on power and pragmatism, also touched upon the importance of communal values and norms. Thucydides, for instance, showed how alliances and shared interests among city-states were crucial in the Peloponnesian War, pointing to a form of order and restraint that arises from these connections. Classical realists do not view international relations as merely a relentless power struggle in a vacuum of moral considerations. Instead, they see the international arena as a complex tapestry where power politics are interwoven with shared norms and a sense of community. This blend influences how states behave, how they perceive their interests, and how they exercise restraint, thus contributing to the maintenance of order in both domestic and international spheres.
