Within realism, there are several sub-types or variations of the theory:
1. Political realism: This traditional approach to realism emphasizes the role of power and national interests in international relations. It assumes that states are the primary actors, seek to maximize their power and security, and are often willing to use force or coercion to achieve their goals.
2. Neo-realism: Emerging in the 1970s, neo-realism is a more structural and systemic version of realism. It focuses on the international system as the main determinant of state behavior, arguing that the anarchical nature of the international system, where there is no overarching authority, leads states to prioritize their own security and power.
Types of Non-Realist Approaches
There are several non-realist approaches that provide alternative perspectives to understanding international relations:
1. Liberalism: Liberalism emphasizes the role of cooperation, economic interdependence, and international institutions in promoting peace and prosperity among nations. It argues that economic interdependence, democratic governance, and the spread of human rights can reduce conflict and promote cooperation between states.
2. Constructivism: Constructivism argues that social and political realities are constructed through shared ideas, norms, and identities rather than being objective facts. It focuses on the role of ideas and concepts in shaping international relations, and how these ideas shape state identities, interests, and behaviors.
3. Marxism: Marxist approaches view the international system through the lens of class struggle and economic structures. They argue that the global economy, dominated by capitalist systems, and the inequalities it produces are the root causes of conflict and oppression in international relations.
4. Feminism: Feminist approaches critique traditional theories of international relations for being androcentric and neglecting the role of gender. They focus on the experiences of women in international relations, the gendered dimensions of power and conflict, and the need for gender equality to achieve peace.
5. Postcolonialism: Postcolonialism challenges the Eurocentric perspective of traditional international relations theories. It examines how colonialism and its legacy continue to shape global power structures, inequalities, and international relations, particularly from the perspective of former colonies.
6. Environmentalism: Environmentalism emphasizes the role of environmental issues and concerns in international relations. It examines the impact of human activities on the environment, the challenges of climate change and resource scarcity, and the need for international cooperation to address these global problems.
These theories offer different lenses for analyzing and understanding world affairs, providing diverse perspectives on the nature of international relations, the causes of conflict and cooperation, and the possibilities for achieving peace and stability in a complex and interconnected world.
