National Interest is an essentially contested concept. Comment. (2022, 10 Marks)
W. B. Gallie (1956) called a concept essentially contested when competent users permanently dispute its proper use because the quarrel is really about the values it carries. National interest fits closely. It presumes a state-centric world of unitary, rational actors, yet every school answers differently what the interest is, who defines it and how.
Why the concept is contested
- Rival cores. Hans J. Morgenthau (Politics Among Nations, 1954 edition) defines interest in terms of power; Kenneth N. Waltz (Theory of International Politics, 1979) makes security the first aim. Both terms are themselves open-ended: Arnold Wolfers (1952) showed “national security” to be an ambiguous symbol covering opposite policies.
- Objective or subjective. Joseph Frankel (National Interest, 1970) separated an objective approach (interests fixed by geography and anarchy) from a subjective one (preferences of decision-makers), and urged a synthesis as domestic and foreign policy overlap.
- Whose interest? Charles A. Beard (The Idea of National Interest, 1934) showed the phrase filled by whichever economic interests held power. Robert Michels’s iron law of oligarchy points the same way: a few decide, and the national label legitimises their choice as the will of all.
- Constructed, not discovered. Martha Finnemore (National Interests in International Society, 1996) and Jutta Weldes (Constructing National Interests, 1999) treat interests as products of norms and official discourse.
- No rational definition. Raymond Aron (Peace and War, 1962) held that the plurality of concrete and ultimate objectives forbids one; critics therefore call it a pseudo-theory that explains any outcome after the event.
Contestation in practice
After 2022 New Delhi defended discounted Russian crude as energy security and strategic autonomy; S. Jaishankar (October 2025) put it as maximising my opportunities and maintaining my freedom of choice. Critics saw refiners’ windfalls and a strained US partnership; Washington imposed a 25% penalty tariff in August 2025, lifted it in February 2026, and in September 2026 enacted authority for tariffs of up to 100% on buyers of Russian oil. One policy, three readings of the “national” interest.
Why it survives
Contestation does not empty the concept. At the level of survival and territorial integrity, Morgenthau’s irreducible minimum, agreement is wide; dispute multiplies over variable interests. Requiring governments to say which interest a commitment serves also makes foreign policy answerable.
Conclusion
National interest is contested at its variable edge and largely agreed at its core. That is its function rather than a flaw: the argument over whose interest, defined how, is the democratic substance of foreign policy.
