## Positions at a glance

### Supporters

The core of Wendt's framework rests on three propositions: that structures are constituted by shared ideas rather than material forces alone, that the identities and interests of states are constructed by these shared ideas rather than given exogenously by human nature or domestic politics, and that agents and structures are mutually constitutive — neither is reducible to the other. He distinguished three "cultures of anarchy," each organised around a dominant role-relationship: a Hobbesian culture where states treat one another as enemies, a Lockean culture of rivals who accept each other's right to exist (the modern Westphalian norm), and a Kantian culture of friends who renounce violence and practise collective security. Crucially, Wendt is a "thin" or systemic constructivist who shares positivist and rationalist assumptions about state-as-actor with the realists he criticises, distinguishing him from the more radical post-structuralists; he is sometimes labelled a proponent of "scientific realism."

### Opponents

Alexander Wendt (born 1958 in Mainz, Germany) is the political scientist most closely identified with social constructivism in International Relations. His reputation rests principally on the 1992 International Organization article "Anarchy Is What States Make of It: The Social Construction of Power Politics" and the systematic 1999 monograph Social Theory of International Politics. Writing against the dominant neorealism of Kenneth Waltz and the neoliberal institutionalism of Robert Keohane, Wendt argued that the central categories of world politics — anarchy, power, interest, the security dilemma — are not material givens but social constructions produced by inter-subjective understandings, shared ideas, and the historical practice of states. His celebrated dictum is that "anarchy is what states make of it": the international system has no fixed logic independent of the meanings actors attach to it.

Example

In his 1992 article, Alexander Wendt argued that 500 British nuclear weapons threaten the United States less than 5 North Korean weapons, because meaning derives from social relationships of amity or enmity, not raw capability.
