Discuss the emergence of neo-realism and its basic tenets. (2021, 15 Marks)
Neo-realism, or structural realism, is the reconstruction of realism by Kenneth N. Waltz in Theory of International Politics (1979). It kept classical realism’s conclusions (conflict, power and balance) but moved their cause from human nature to the structure of the international system.
Why it emerged
- The weakness of classical realism. Hans J. Morgenthau rooted the struggle for power in man’s animus dominandi. Waltz objected that human nature is a constant, and a constant cannot explain why some eras see general war and others do not. Classical realism also lacked tools for systematic explanation.
- The demand for scientific theory. Waltz rejected the behaviouralists’ inductive fact-gathering but accepted their demand for testable theory. He built a deductive one on the model of micro-economics: the system is like a market whose structure constrains firms whatever their wishes.
- Groundwork in the third image. Man, the State and War (1959) had already found the permissive cause of war in anarchy, not in individuals or regimes.
- The liberal challenge of the 1970s. During détente, Robert O. Keohane and Joseph S. Nye argued in Power and Interdependence (1977) that complex interdependence was eroding power politics. Waltz set out to show that realism was timeless, and the renewed Cold War from 1979 made the claim credible. The label stuck through critics such as Richard K. Ashley (“The Poverty of Neorealism”, 1984) and Keohane’s edited Neorealism and Its Critics (1986).
Basic tenets
- Anarchy as ordering principle. Domestic politics is hierarchical; international politics has no common government. Anarchy means the absence of authority, not chaos.
- Like units. States perform the same functions, so they differ in capability, not in kind.
- Distribution of capabilities. Polarity is the only structural variable that changes.
- Self-help. In Waltz’s words, “self-help is necessarily the principle of action” in an anarchic order.
- Security, not power, is the goal. Power is a means to survival, which later grounds defensive realism.
- Security dilemma. One state’s armament is another’s threat, so arms races follow even among cautious states.
- Balance of power. Balances form through internal and external balancing whatever states intend.
- Relative gains. Joseph M. Grieco (1988) argued that fear of a partner’s greater gain limits cooperation.
- Bipolar stability. Two great powers mean fewer miscalculations than many.
- A theory of international politics, not of foreign policy. It explains recurring outcomes, not particular decisions.
Assessment
- Strengths: parsimony, and an account of the long peace of bipolarity. The expiry of New START on 5 February 2026, with no successor, returns the two largest arsenals to self-help, as the theory predicts.
- Limits: it did not foresee the Cold War’s peaceful end. Alexander Wendt answered that anarchy is what states make of it, and Mohammed Ayoob‘s subaltern realism showed that post-colonial states fear threats from within more than the system above them.
Conclusion
Neo-realism made realism a systemic science. Its later revisers, offensive and neoclassical alike, still start from its structural premises, though India’s and other post-colonial experiences show that structure alone cannot explain what states fear.
