Defensive Realism vs. Neoclassical Realism

Attribute	Defensive Realism	Neoclassical Realism
Focus on security	Emphasizes the importance of security and survival in international relations	Also prioritizes security concerns, but incorporates other factors such as domestic politics and economics
State behavior	States are primarily concerned with ensuring their own security and survival	States are influenced by both external security threats and internal factors
International system	Views the international system as anarchic and characterized by self-help and competition	Recognizes the importance of the international system, but also considers the impact of domestic factors on state behavior
Power dynamics	Focuses on the distribution of power among states and how it affects their behavior	Considers power dynamics, but also looks at how states' perceptions and interpretations of power influence their actions

Introduction

Realism is a prominent theory in international relations that focuses on the idea that states are the primary actors in the international system and that they are primarily concerned with their own security and survival. Within the realm of realism, there are different sub-theories that offer varying perspectives on how states behave and interact with one another. Two of the most well-known sub-theories of realism are Defensive Realism and Neoclassical Realism. While both theories share some similarities, they also have distinct attributes that set them apart.

Defensive Realism

Defensive Realism, also known as Structural Realism, is a theory developed by Kenneth Waltz that emphasizes the anarchic nature of the international system. According to Defensive Realism, states are primarily concerned with ensuring their own security and survival in a world where there is no overarching authority to enforce rules or prevent conflict. States are seen as rational actors that seek to maintain a balance of power to deter potential threats from other states. Defensive Realism argues that states will act defensively to protect themselves from external aggression, rather than seeking to expand their power or influence at the expense of others.

• Emphasizes the anarchic nature of the international system
• States are primarily concerned with ensuring their own security and survival
• States seek to maintain a balance of power to deter potential threats
• States act defensively to protect themselves from external aggression

Neoclassical Realism

Neoclassical Realism is a theory that builds upon the foundations of Defensive Realism but incorporates domestic factors into the analysis of state behavior. Developed by scholars such as Gideon Rose and Stephen Walt, Neoclassical Realism argues that while the international system is anarchic, states' actions are also influenced by internal factors such as leadership, national identity, and domestic politics. Neoclassical Realism suggests that states' foreign policies are shaped not only by external threats but also by their leaders' perceptions and interpretations of those threats. This theory posits that states' behavior is a result of the interaction between the international system and domestic factors.

• Incorporates domestic factors into the analysis of state behavior
• States' actions are influenced by internal factors such as leadership and national identity
• Foreign policies are shaped by leaders' perceptions of external threats
• States' behavior is a result of the interaction between the international system and domestic factors

Comparison

While both Defensive Realism and Neoclassical Realism fall under the broader umbrella of realism and share some commonalities, they also have distinct attributes that differentiate them from each other. Defensive Realism focuses primarily on the anarchic nature of the international system and states' efforts to ensure their security through a balance of power. In contrast, Neoclassical Realism incorporates domestic factors into the analysis, suggesting that states' behavior is influenced by both external threats and internal dynamics.

Defensive Realism's emphasis on the balance of power and states' defensive actions reflects a more structural view of international relations, where states' behavior is shaped by the constraints of the system. On the other hand, Neoclassical Realism's incorporation of domestic factors allows for a more nuanced understanding of state behavior, taking into account the role of leaders, national identity, and domestic politics in shaping foreign policy decisions.

Another key difference between Defensive Realism and Neoclassical Realism lies in their explanations of state behavior. Defensive Realism argues that states act defensively to protect themselves from external threats, while Neoclassical Realism suggests that states' actions are also influenced by internal factors such as leadership perceptions and interpretations of threats. This distinction highlights the importance of considering both external and internal factors in understanding state behavior.

Conclusion

In conclusion, Defensive Realism and Neoclassical Realism are two sub-theories of realism that offer different perspectives on how states behave in the international system. While Defensive Realism emphasizes the anarchic nature of the system and states' efforts to ensure their security through a balance of power, Neoclassical Realism incorporates domestic factors into the analysis, suggesting that states' behavior is influenced by both external threats and internal dynamics. Both theories provide valuable insights into state behavior and offer complementary perspectives on the complexities of international relations.
