Ryan Castillo: You had that look on your face when you walked in — the one that means you found something that doesn't add up.
Jordan Hale: The Westphalian myth. That's the episode. And I keep — look, I keep starting to explain it to people and watching their faces go flat, like "okay, international relations, very dry" — but the entry point is genuinely wild. Not the concept. The history.
Ryan Castillo: Give me the entry point.
Jordan Hale: The Peace of Westphalia — May through October 1648, two treaties, two cities, Münster and Osnabrück — because the negotiating parties would not be in the same building. That's how the modern international order was born. People who couldn't stand to be in the same room signing documents across two different cities.
Ryan Castillo: Two cities — is that a logistical thing or a deliberate signal?
Jordan Hale: Deliberate. Catholics in Münster, Protestants in Osnabrück — the religious split that had just spent thirty years killing somewhere between thirty and forty percent of the population in parts of the Holy Roman Empire. Thirty to forty percent. From 1618 to 1648.
Ryan Castillo: That number — thirty to forty percent — that's not uniform across the empire, right? That's regional peaks.
Jordan Hale: Parts of it, yeah. Some regions just — decimated. And then 1648 arrives and suddenly we have this thing we call territorial sovereignty: a state has supreme authority within its borders, no external power interferes. Clean, elegant, modern. Except — wait, no — except that's not actually what the 1648 documents say. That's what twentieth-century IR theorists said the documents said.
Ryan Castillo: Hold on — the principle itself was retrofitted?
Jordan Hale: Retroactively attributed. The Westphalian myth — that's the actual scholarly term now — is the argument that later theorists needed a founding moment for the state-centric international order, and Westphalia was convenient.
Ryan Castillo: Which means the pre-Westphalian order — overlapping feudal claims, papal supremacy over territorial questions, fluid borders — that was never cleanly replaced in 1648. It just got a new story told about it.
Jordan Hale: And the question that doesn't go away is — if the foundation is mostly story, why does it still hold?
Ryan Castillo: Because it works like a neighbor agreement with no lawyer involved. Two people who've been in a brutal feud, they stop fighting, they say: your yard is yours, my yard is mine, and we stop asking who deserved it. No judge, no referee. Just mutual recognition that the alternative is worse. That's the whole Westphalian system in one sentence — and the foundation doesn't actually need to be ancient to hold.
Jordan Hale: But then you look at what Spain actually signed at Münster and it's — wait, it's so much smaller than the myth.
Ryan Castillo: That's the concrete thing. The one clear sovereign-recognition act in the Peace of Westphalia: Spain formally recognized the Dutch Republic as an independent state. That's real, that happened. But the grand principle — territorial sovereignty as a universal norm — that got layered on afterward by theorists who needed a founding moment.
Jordan Hale: So Spain and the Dutch Republic shake hands — that's specific, that's documented — and then two centuries of scholars go, you know, 'that must mean everyone agreed on everything.'
Ryan Castillo: The non-interference norm, the state-centric order — those weren't codified in a single moment in 1648. They accumulated. Gradually, through practice, through later treaties, through international law building on itself.
Jordan Hale: Which is kind of — I mean, that's almost more interesting? Like, the system didn't come from a genius blueprint. It came from states repeatedly finding the same answer useful and eventually calling it a principle.
Ryan Castillo: Right, but — does it undermine it? The international order operates inside what Hedley Bull called international anarchy — no world government above states, nothing enforcing compliance. The Westphalian myth fills that vacuum by giving states a shared story about why the rules are legitimate.
Jordan Hale: Wait — so the myth isn't a flaw, it's actually doing load-bearing work.
Ryan Castillo: Exactly — and that's the part scholars are wrestling with. States needed a founding moment to legitimate norms they wanted enforced. Westphalia was convenient. The story made the rules feel inevitable.
Jordan Hale: It's like — okay, every country has a founding myth, right, some moment where everything became real and legitimate. America has 1776. France has the Revolution. The international order has 1648. And the actual documents are almost beside the point because the myth does the political work the documents couldn't.
Ryan Castillo: And the UN Charter eventually codified the non-interference norm formally — but even that is centuries after Westphalia. So the question isn't really whether 1648 was the birth moment. It's whether a system born from constructed narrative can hold under pressure the same way a system born from, I don't know, actual design might.
Jordan Hale: And I don't think we have a clean answer to that — because the pressure cases are exactly where the complexity shows up.
Ryan Castillo: The pressure cases are where the mechanism shows itself, though — and the mechanism is a coordination problem. Like, a genuine one. Hedley Bull's framing in 'The Anarchical Society' is that in a world with no world government, order doesn't come from enforcement. It comes from shared norms. And the heaviest load-bearing norm is non-interference.
Jordan Hale: Wait — load-bearing as in, pull it out and the whole thing falls?
Ryan Castillo: That's the claim. Picture a trade negotiator sitting down to draft a cross-border deal. Before she gets to tariffs — before any of it — both sides have to implicitly agree that each government actually controls its own territory and speaks for it. That prior agreement is the handshake under every handshake. Without territorial sovereignty assumed, the negotiation doesn't start.
Jordan Hale: It's invisible infrastructure. You don't see it because it's working.
Ryan Castillo: And that's why the myth question almost doesn't matter for durability. The system persists not because 1648 was real, but because there's no alternative equilibrium that simultaneously gives you security, legitimacy, and order.
Jordan Hale: Which is — I mean, that's kind of bleak, actually? Like, the UN Charter enshrines the non-interference principle formally, right, Article 2 and all of it. And you'd think that's the moment the system gets real backing. But even the UN is built on the same logic — member states consented to join, they retain formal sovereignty, the institution doesn't sit above them. It derives authority from them.
Ryan Castillo: Same with the European Union. The EU can override member state law in certain areas — that sounds like it breaks the Westphalian frame. But member states consented to join. They retain formal sovereignty. The institution's authority flows upward from states, not downward from something above them.
Jordan Hale: So the EU isn't a counter-example to the state-centric international order. It's... actually the order doing something new inside itself.
Ryan Castillo: Right — but here's the sharper version of the question. Is the system durable because it's correct, or because contesting it is catastrophically expensive? Those are different things.
Jordan Hale: No, I think — wait, actually that distinction matters less than it sounds, because in a coordination problem the cost of defection IS the mechanism. If every territorial claim became renegotiable at once, you don't get a better system. You get every border on earth in play simultaneously. That's not reform, that's — I don't even know what that is.
Ryan Castillo: Chaos is the technical term.
Jordan Hale: It's a coordination trap. States are locked in not because they love the system but because exit destroys the thing exit depends on. And that — you know, that's actually why the hypocrisy angle gets so disturbing when you follow it forward. Because the same system that solved the coordination problem in Europe got applied selectively — and there's a part of that story, what they did with it outside Europe, that makes this whole durability argument way harder to sit with.
Ryan Castillo: And the humanitarian interventions in Somalia, Bosnia, Sudan — those are where the internal contradiction resurfaces in real time. We'll get there.
Jordan Hale: But the selective part — that's not a footnote, that's the whole thing. The Mosul Vilayet. After World War I, you have this territory that is ethnically and religiously distinct from Iraq — it's got its own population, its own history — and the League of Nations just votes to hand it to Iraq anyway. 1925. The same institution built to enforce the rules.
Ryan Castillo: And the British are already there when the vote happens.
Jordan Hale: Occupying it, yeah. Which is — I mean, the non-interference norm that was supposed to protect European sovereignty just... didn't travel. It stopped at the water's edge.
Ryan Castillo: It couldn't have traveled. If territorial sovereignty applied universally, colonialism was illegal on its own terms. The architecture required the exclusion.
Jordan Hale: That's — wait, say that again.
Ryan Castillo: The system only stabilized Europe by exporting instability everywhere else. That's not a bug that crept in. Non-interference was never designed to be universal. It was designed to manage European-on-European conflict.
Jordan Hale: Which makes the 'universal international order' framing — you know, the whole state-centric international order presenting itself as neutral — that's the legitimating fiction. It was European hierarchy with a Latin name.
Ryan Castillo: Now look at what happens when that same tension resurfaces late in the twentieth century. Somalia, Bosnia, Sudan, Haiti — the UN Security Council authorizes military intervention in each of those cases. Domestic affairs. Direct violation of the non-interference norm.
Jordan Hale: The Responsibility to Protect framework — that's the emerging norm that's supposed to justify it.
Ryan Castillo: Right — but here's the structural thing that doesn't get enough attention. Who authorized those interventions? The Security Council. And the Security Council's legitimacy derives entirely from sovereign member states. So even the challenge to Westphalian sovereignty gets routed through Westphalian architecture.
Jordan Hale: The system absorbed its own violation.
Ryan Castillo: Which is exactly why China is the clearest living case of this. China adheres loudly to sovereignty and non-interference norms — rhetorical commitment, every diplomatic statement — because those norms are the thing protecting its domestic authority from external challenge. The system's most visible skeptic is also its most committed defender.
Jordan Hale: No way. The country that most wants to revise the order is also the country keeping the core norm alive because the core norm is the thing that says 'don't touch what's inside our borders.'
Ryan Castillo: And that's the counterintuitive core. The system doesn't break under pressure — it reconstitutes. Because the unanswerable question is still sitting there underneath it all: if territorial sovereignty collapses, whose claims are valid? Every state with a border dispute becomes ungovernable simultaneously. That cost is what holds it.
Jordan Hale: And that's what sticks with me when we close this out. Because the question that stays with me — you know, not the abstract coordination stuff, but the actual human thing — is what does this system feel like from inside it if you don't have a state? Like, the Kurds. The Palestinians. They exist inside an order built on the absolute principle that borders are settled and interference is forbidden. Their claim isn't just unrecognized — it's structurally unrecognizable. The vocabulary doesn't have a word for them.
Ryan Castillo: The coordination trap forecloses them by design. Not malice — structure. If every territorial claim became renegotiable, you don't reform the system. You put every border on earth in play at once. So the system can't open for the Kurds without opening for everyone, and that cost is what keeps it shut.
Jordan Hale: And the myth did that. I mean — the Westphalian myth, states needing a founding moment to legitimate the norms they wanted enforced, 1648 as the clean origin story — that story made the borders feel inevitable. Which means the people outside the borders feel inevitable too. Like a category error, not an injustice.
Ryan Castillo: That's probably the most unsettling thing in this whole conversation. The system persists not because it's legitimate but because renegotiating it requires states to agree on what replaces it — before giving up the only thing preventing constant war over territory. That's the trap. And there's no exit that doesn't require solving the question the system was built to never ask.
Jordan Hale: Whose claim is actually valid.
Ryan Castillo: Which the Thirty Years' War already answered, in its way. Thirty to forty percent of some populations, gone. Nobody wanted to ask it again.
Jordan Hale: I think that's where I actually land. Not satisfied, just — that's where the ground stops. Two cities, two treaties, a myth built on top of a war nobody survived cleanly. And it's still the floor we're standing on. That's a strange thing to sit with.
