Comment: The realist vision of ‘national interest’. (2004, 20 Marks)
For realists, national interest is not one concept among many but the organising idea of international politics. Hans J. Morgenthau made interest defined in terms of power the second of the six principles added to Politics Among Nations in its second edition (1954), calling it the main signpost through the landscape of world politics. The realist vision holds that in an anarchic system each state must define its interest in terms of survival and power, and that statesmen who forget this endanger their states.
Roots of the vision
- Thucydides’ Melian dialogue, in which the strong do what they can and the weak suffer what they must, states the oldest form of the claim.
- Kautilya’s Arthashastra subordinated every policy to the gain and security of the kingdom, and his mandala treated the neighbour as the natural rival.
- Niccolò Machiavelli and the later doctrine of raison d’état freed the ruler’s reckoning of state necessity from private morality.
- E. H. Carr (The Twenty Years’ Crisis, 1939) exposed the liberal harmony of interests as the ideology of satisfied powers.
Morgenthau’s classical formulation
- The irreducible minimum. Every state must protect its physical, political and cultural identity against other states. This core is fixed; around it lie variable interests shaped by circumstance.
- Interest as a constitutional generality. Morgenthau compared it to the great generalities of a constitution, such as due process: vague at the edge, binding at the centre.
- Against crusades. Interest is limited; ideology is not. His rules of diplomacy require that diplomacy be divested of the crusading spirit, that objectives be defined in terms of the national interest and backed by adequate power, and that nations compromise on every issue not vital to them.
- Prudence as morality. Political ethics judges an action by its consequences. George F. Kennan made the same attack on the legalistic-moralistic tradition in US policy.
Neorealist and later refinements
- Kenneth N. Waltz (Theory of International Politics, 1979) moved the source of interest from human nature to structure: states seek at least their own survival.
- Defensive realists say states maximise security; John J. Mearsheimer’s offensive realism (2001) says they maximise relative power, ideally regional hegemony.
- Neoclassical realists such as Gideon Rose (1998) add leaders’ perceptions and domestic capacity as filters between structure and policy.
The Indian strand
Jawaharlal Nehru, author of non-alignment, told the Constituent Assembly on 4 December 1947 that in the ultimate analysis, a government functions for the good of the country it governs. Kanti Bajpai (2002) finds a hyperrealist stream in Indian strategic thought beside Nehruvian and neoliberal ones, and S. Jaishankar’s The India Way (2020) recasts diplomacy in openly realist terms. Operation Sindoor after the Pahalgam attack (2025) is interest defined as security.
Critiques
- Indeterminacy. Raymond Aron (Peace and War, 1962) held that a state’s plural objectives forbid any rational definition of its interest, hence the charge of pseudo-theory; Arnold Wolfers (1952) called national security an ambiguous symbol.
- Whose interest? Charles A. Beard and Marxists see a governing coalition’s interest presented as the nation’s.
- Liberals such as Robert O. Keohane show that interdependence and institutions make absolute gains and cooperation rational.
- Constructivists led by Alexander Wendt argue that interests follow identity; J. Ann Tickner (1988) showed that Morgenthau’s principles reflect a masculine reading of power and neglect economic and human security.
Conclusion
The realist vision is the indispensable starting point: it explains continuity across governments and disciplines moral overreach. Its weakness is that it treats interests as given when they are made. A sound reading keeps the realist core of survival and power while accepting that what states count as power and security keeps changing.
