The domestic analogy is a mode of reasoning in international relations theory that transfers concepts, institutions, and norms from domestic political life — citizens, contracts, police, courts, legislatures — onto the society of states. If individuals inside a state require law, government, and enforcement to escape disorder, the analogy suggests that states in the international arena likewise need rules, collective security, and adjudicative bodies to escape anarchy.
The reasoning runs through much of the liberal-internationalist canon. Hobbes used it inversely, comparing sovereigns to individuals in a state of nature but doubting that an international Leviathan was necessary. Kant's Perpetual Peace (1795) extended it positively, proposing a federation of republics. Twentieth-century architects of the League of Nations and the United Nations relied on it heavily: collective security under Article 16 of the Covenant and Chapter VII of the UN Charter treats aggression against one state as analogous to a crime against the community, warranting a police-like response.
The analogy has been sharply criticised. Hedley Bull, in The Anarchical Society (1977), warned that international society differs fundamentally from domestic society: states are functionally similar, unequal in power, and lack a monopoly on legitimate violence. Hidemi Suganami's The Domestic Analogy and World Order Proposals (1989) is the standard book-length treatment, distinguishing weaker analogies (borrowing specific institutions) from stronger ones (treating the world as a single polity).
Common uses today include:
- Arguments for a standing UN army or stronger Security Council enforcement.
- Proposals for global constitutionalism or world federalism.
- Framing of R2P as analogous to a state's duty to protect citizens.
- Treating international criminal law (ICC, ad hoc tribunals) as the equivalent of domestic criminal courts.
Realists and pluralists resist the analogy, arguing it obscures sovereignty, cultural diversity, and the absence of a global demos. Solidarists and cosmopolitans embrace it as a guide to reform.
Example
Advocates of a permanent UN rapid-reaction force often invoke the domestic analogy, comparing it to a municipal police force protecting citizens from violent offenders.
Frequently asked questions
It is not attributable to a single author, but Hidemi Suganami's 1989 book 'The Domestic Analogy and World Order Proposals' is the canonical scholarly treatment and gave the concept its modern label.
