A living proto-planetary design, offering insight into the careful architecture of institutions and forms of governance at planetary scale.
“We are in a world in which global challenges are more and more integrated, and the responses are more and more fragmented, and if this is not reversed, it's a recipe for disaster”
– António Guterres, Secretary-General, United Nations
For most of modern history, sovereignty meant total, indivisible control over a nation’s territory, weapons, and choices. No outside force could legally interfere. But nuclear technology broke this logic.
a slow and painful move from sovereignty as absolute control toward
sovereignty as segmented, pooled, and collectively managed, especially over technologies too dangerous to be left to single states.
These obligations are intrusive and onerous to nation-states, who often perceive them as a clear violation of national sovereignty.
But, again and again, states allow IAEA inspectors through the door of their tightly secured nuclear facilities.
In 2021, about 275 international inspectors scrutinized items across over 1300 nuclear facilities around the world. 4 States may grouse, but the system works.
The IAEA as proto-planetary institution emerged at the confluence of specific tipping points: moments when collective risk forced states to cooperate under new frameworks. Understanding this history helps us assess whether today’s planetary challenges might create conditions for new, more comprehensive institutions.

In October 1962, the United States discovered Soviet nuclear missiles being secretly installed in Cuba, just 90 miles from Florida. Confronted with the terrifying possibility of mutually assured destruction, President John F. Kennedy imposed a naval “quarantine” around Cuba and demanded immediate removal of the missiles. Behind tense diplomatic exchanges, both superpowers mobilized forces and prepared for potential nuclear strikes.

For thirteen days, the world stood on the precipice of nuclear war. Ultimately, Soviet Premier Nikita Khrushchev agreed to withdraw the missiles in exchange for a U.S. pledge not to invade Cuba and the secret removal of American Jupiter missiles from Turkey. This event marked the closest point the Cold War came to escalating into full-scale nuclear war, and prompted the creation of an unprecedented international institution.

Sovereignty concerns.
With the IAEA, the unique and severe threat of immediate annihilation has prompted the development of a unique and, to some eyes, severe international response.
Unlike so many problems that face humankind, the international community has responded with a global body that can violate state sovereignty for the sake of the common good.
The IAEA's history demonstrates that states, even major powers, can agree to delegate a segment of their sovereignty to a technocratic international body when faced with a sufficiently grave and undeniable shared existential threat that they cannot manage alone. But this arrangement emerged out of institutional evolution after a crisis. The Cuban Missile Crisis served as a critical catalyst, scaring superpowers into accepting verification measures they had previously rejected.
What principles can we extrapolate from the design of the IAEA to design an institutional response to today’s planetary challenges?
This segmented sovereignty allows for the emergence of planetary institutions:
specialized,
technocratic bodies
with delegated powers
to manage global risks.
These institutions operate across and within segments, enabling collective governance without erasing national identities.
How does IAEA differ from other multilateral institutions? What makes it proto-planetary rather than merely global?
Member states have authorized the IAEA to conduct on-the-ground inspections of nuclear facilities and verify compliance with the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).
The IAEA, in other words, is a consistent and effective mechanism for resolving high-stakes international collective action problems. Unique among multilateral organizations, the agency's authority in non-proliferation arguably supersedes the otherwise-ironclad international norm that each state holds the power to determine compliance with global commitments. And this authority has only increased over time, with the 1997 Additional Protocol granting the agency stronger inspection rights.
However, the model is not without limitations. Political considerations can still override technical findings, as happened with the US invasion of Iraq despite IAEA inspectors (under Hans Blix) finding no evidence of active WMD programs. Furthermore, the level of state compliance varies across the IAEA's mandates, being strongest for non-proliferation and weaker for disarmament, nuclear safety, and peaceful uses.
