Transcript

Fletcher EN

A Japanese shipping company called Mitsui O.S.K.

Lines put out a statement this week saying three of their ships crossed the Strait of Hormuz last month and didn't pay Iran's transit fees.

And I've been turning that over in my mind, because there's something buried in it that I think most people are missing completely.

Octavio ES

Sí, y lo que me parece interesante es que Mitsui no dijo que se negaron a pagar.

Yes, and what I find interesting is that Mitsui didn't say they refused to pay.

Dijeron que simplemente...

They said they simply...

no pagaron.

didn't pay.

Es una diferencia pequeña en las palabras, pero enorme en la diplomacia.

It's a small difference in words, but enormous in diplomacy.

Fletcher EN

Right, and that careful language tells you everything about the position Japan is in.

They don't want to endorse the fees, because that legitimizes Iran's claim over an international waterway.

But they also really, really can't afford to antagonize Tehran.

Octavio ES

Exactamente.

Exactly.

Y para entender por qué Japón está en esa posición tan incómoda, hay que entender algo fundamental: Japón es una isla.

And to understand why Japan is in such an uncomfortable position, you have to understand something fundamental: Japan is an island.

Una isla grande, sí, pero con casi ningún recurso natural propio.

A large island, yes, but with almost no natural resources of its own.

Sin petróleo, sin gas natural en cantidades importantes, sin hierro suficiente.

No oil, no significant natural gas, not enough iron.

Todo tiene que llegar por barco.

Everything has to arrive by ship.

Fletcher EN

And I want to put a number on that, because the abstract version doesn't quite land.

Japan imports roughly ninety percent of its energy.

Ninety.

And of its oil imports, more than ninety percent comes from the Middle East, much of it through the Strait of Hormuz.

Octavio ES

Es un número que asusta cuando lo piensas bien.

It's a number that frightens you when you really think about it.

Imagina que tu casa depende de un solo tubo de agua, y ese tubo pasa por el jardín de un vecino con el que tienes una relación...

Imagine your house depends on a single water pipe, and that pipe runs through the yard of a neighbor with whom you have a complicated relationship.

complicada.

That is Japan's energy situation.

Así es la situación energética de Japón.

Fletcher EN

And it's not just oil.

Think about food.

Japan imports more than sixty percent of its calories.

The container ships moving through these lanes, they're not carrying luxury goods.

They're carrying the means by which a hundred and twenty-five million people eat.

Octavio ES

Fletcher, permíteme añadir algo de historia aquí, porque esto no es nuevo.

Fletcher, let me add some history here, because this isn't new.

Esta vulnerabilidad es el contexto de casi toda la historia japonesa del siglo veinte.

This vulnerability is the context for almost all of twentieth-century Japanese history.

Japón sabía que necesitaba recursos, y en los años treinta decidió ir a buscarlos por la fuerza.

Japan knew it needed resources, and in the 1930s it decided to go find them by force.

Fletcher EN

Which is where you get the invasion of Manchuria, the drive into Southeast Asia, the whole logic of the so-called Greater East Asia Co-Prosperity Sphere, which was essentially an empire designed to secure raw materials Japan didn't have at home.

Octavio ES

Y el momento decisivo fue cuando Estados Unidos cortó el suministro de petróleo a Japón en 1941.

And the decisive moment was when the United States cut off Japan's oil supply in 1941.

Ese embargo fue, en parte, lo que precipitó el ataque a Pearl Harbor.

That embargo was, in part, what precipitated the attack on Pearl Harbor.

Japón calculó que si no podía comprar el petróleo, tenía que conquistarlo, y eso significaba atacar a Estados Unidos antes de que Estados Unidos pudiera detenerlos.

Japan calculated that if it couldn't buy the oil, it had to conquer it, and that meant attacking the United States before the United States could stop them.

Fletcher EN

I've spent a lot of time with that decision, and it remains one of the most catastrophically misjudged strategic calculations of the modern era.

But the underlying anxiety, the island nation surrounded by a world that controls what it needs to survive, that anxiety is completely rational.

Octavio ES

Y ese es el punto que quiero que los oyentes tengan en la cabeza.

And that is the point I want listeners to keep in mind.

Cuando Japón mira el Estrecho de Ormuz hoy, no solo ve una crisis regional.

When Japan looks at the Strait of Hormuz today, it doesn't just see a regional crisis.

Ve un fantasma.

It sees a ghost.

Ve la misma vulnerabilidad que existía en 1941, pero ahora tiene que gestionarla sin ejército propio, sin la opción de la fuerza.

It sees the same vulnerability that existed in 1941, but now it has to manage it without its own army, without the option of force.

Fletcher EN

Which brings us to Article Nine of Japan's postwar constitution, which renounces war as a sovereign right and prohibits Japan from maintaining war potential.

It was written in 1947 under American occupation and it's been the defining constraint on Japanese foreign policy ever since.

Octavio ES

Es una paradoja fascinante.

It's a fascinating paradox.

La potencia que cortó el petróleo de Japón y provocó la guerra es la misma que luego escribió la constitución que prohíbe a Japón volver a hacer la guerra.

The power that cut off Japan's oil and provoked the war is the same one that then wrote the constitution prohibiting Japan from going to war again.

Y durante décadas, esa misma potencia prometió proteger a Japón a cambio.

And for decades, that same power promised to protect Japan in exchange.

Fletcher EN

The security umbrella.

The alliance that says: you don't need to defend your own shipping lanes because we'll do it for you.

Which worked reasonably well for eighty years, and is now looking considerably more fragile than it did.

Octavio ES

Claro.

Exactly.

Y lo que hace que la situación actual sea tan interesante es que los barcos de Mitsui cruzaron el estrecho sin pagar, pero el gobierno japonés no ha dicho nada en voz alta.

And what makes the current situation so interesting is that Mitsui's ships crossed the strait without paying, but the Japanese government has said nothing aloud.

Ni a favor ni en contra.

Neither for nor against.

Es el silencio diplomático más calculado del mundo.

It's the most calculated diplomatic silence in the world.

Fletcher EN

Because Japan has to maintain working relations with Iran, it gets twelve to fifteen percent of its oil from there historically, while also not undermining the American position that Iran's transit fees are illegitimate.

Threading that needle takes a remarkable amount of patience.

Octavio ES

Y aquí es donde el viaje, el transporte marítimo, se convierte en algo mucho más político de lo que parece.

And this is where travel, maritime transport, becomes much more political than it appears.

Cuando pensamos en viajar, pensamos en turistas, en maletas, en aeropuertos.

When we think about traveling, we think about tourists, suitcases, airports.

Pero el ochenta por ciento del comercio mundial viaja por mar.

But eighty percent of global trade travels by sea.

El mundo que conocemos, los objetos que usamos, dependen de esas rutas.

The world we know, the objects we use, depend on those routes.

Fletcher EN

Let's talk about what a shipping route actually means physically, because I think there's a tendency to treat these as abstract lines on a map.

Mitsui O.S.K.

Lines operates something like nine hundred vessels.

They're moving cars, iron ore, liquefied natural gas.

A single LNG carrier can be three hundred meters long.

Octavio ES

Y el Estrecho de Ormuz tiene solo unos treinta y tres kilómetros de ancho en su punto más estrecho.

And the Strait of Hormuz is only about thirty-three kilometers wide at its narrowest point.

Hay dos carriles de navegación, como una autopista, pero en el mar.

There are two navigation lanes, like a highway, but at sea.

Dos carriles por los que pasa casi el veinte por ciento del petróleo mundial.

Two lanes through which nearly twenty percent of the world's oil passes.

Cuando lo pones en esos términos, la fragilidad es aterradora.

When you put it in those terms, the fragility is terrifying.

Fletcher EN

I covered the first Gulf War from Riyadh and even then the question of Hormuz was always in the background.

Everyone knew it was the pressure point.

You close that strait and you've essentially squeezed the economic windpipe of half the industrialized world.

Octavio ES

Y Japón lo sabe mejor que nadie.

And Japan knows this better than anyone.

Por eso, desde los años ochenta, Japón ha invertido enormemente en diversificar sus fuentes de energía: energía nuclear, que luego se volvió complicada después de Fukushima, renovables, y también rutas alternativas.

That's why, since the 1980s, Japan has invested enormously in diversifying its energy sources: nuclear energy, which then got complicated after Fukushima, renewables, and alternative routes.

Han construido oleoductos y reservas estratégicas para sobrevivir si el estrecho se cierra durante semanas.

They've built pipelines and strategic reserves to survive if the strait closes for weeks.

Fletcher EN

Fukushima is worth a beat here, because it completely reset the calculation.

Before 2011, Japan had about thirty percent of its electricity coming from nuclear power, with plans to increase it.

After the disaster, they shut down almost all of it.

Which meant they suddenly needed vastly more fossil fuels, which meant vastly more dependence on Middle Eastern sea lanes.

Octavio ES

Es irónico, ¿verdad?

It's ironic, isn't it?

Un accidente nuclear doméstico aumentó la dependencia de Japón de un estrecho al otro lado del mundo.

A domestic nuclear accident increased Japan's dependence on a strait on the other side of the world.

Así de interconectadas están las cosas.

That's how interconnected things are.

Una decisión en Fukushima cambia la vulnerabilidad de Japón en el Estrecho de Ormuz.

A decision in Fukushima changes Japan's vulnerability in the Strait of Hormuz.

Fletcher EN

And now bring it back to the present.

Japan under Kishida, and now under Ishiba, has been quietly but systematically chipping away at the pacifist constraints.

Bigger defense budget, new counter-strike capabilities, louder talk about the ability to project force.

Part of that is about China and Taiwan.

But part of it is about exactly this, the sea lanes.

Octavio ES

Sí, y hay un debate muy serio en Japón sobre si el Artículo Nueve todavía tiene sentido en el mundo actual.

Yes, and there's a very serious debate in Japan about whether Article Nine still makes sense in the world today.

No me refiero a los militaristas de derechas, que siempre han querido eliminarlo.

I'm not talking about right-wing militarists who always wanted to eliminate it.

Me refiero a gente razonable que pregunta: si no podemos defender nuestras propias rutas de suministro, ¿somos realmente soberanos?

I'm talking about reasonable people asking: if we can't defend our own supply routes, are we truly sovereign?

Fletcher EN

That's the question, and I don't think it has a clean answer.

The whole postwar order was built on the idea that the United States would guarantee the freedom of the seas, and in return the former Axis powers would remain essentially demilitarized.

That bargain is fraying at both ends simultaneously.

Octavio ES

Y mientras tanto, los barcos de Mitsui siguen navegando.

And meanwhile, Mitsui's ships keep sailing.

Ese es el lado más humano de todo esto.

That's the most human side of all this.

Los marineros que trabajan en esos buques, los capitanes que tienen que decidir si pagan o no cuando un guardacostas iraní se acerca, son ellos quienes viven estas tensiones geopolíticas en tiempo real.

The sailors who work on those vessels, the captains who have to decide whether to pay or not when an Iranian coast guard vessel approaches, they're the ones living these geopolitical tensions in real time.

Fletcher EN

I interviewed a tanker captain once, off the record, during a period of tension in the Gulf.

He described the calculus he did every morning: speed, route, radio contacts, which flags other ships were flying.

He treated it like weather, something you monitor and adapt to, not something you control.

Octavio ES

Me gusta esa imagen.

I like that image.

Y es verdad que el transporte marítimo funciona así: con una enorme cantidad de protocolo, señalización y diplomacia informal.

And it's true that shipping works that way: with an enormous amount of protocol, signaling, and informal diplomacy.

Las compañías navieras tienen relaciones con los puertos, con los pilotos locales que guían los barcos, con los agentes.

Shipping companies have relationships with ports, with local pilots who guide ships, with agents.

Es un mundo de contactos invisibles que mantiene todo en movimiento.

It's a world of invisible contacts that keeps everything moving.

Fletcher EN

And when that invisible network breaks down, and the Hormuz crisis is a breakdown, things stop moving fast.

The tanker that arrived off South Korea this week after crossing Hormuz in mid-April, that was forty-something days.

For a million barrels of crude.

The clock on that matters enormously.

Octavio ES

¿Sabes cuánto tiempo pueden sobrevivir los países con sus reservas estratégicas si el estrecho se cierra completamente?

Do you know how long countries can survive on their strategic reserves if the strait closes completely?

Japón tiene reservas para aproximadamente noventa días.

Japan has reserves for approximately ninety days.

Es mucho, pero no es infinito.

That's a lot, but it's not infinite.

Noventa días para que la diplomacia funcione o para que el mundo encuentre otra solución.

Ninety days for diplomacy to work or for the world to find another solution.

Fletcher EN

Ninety days is a very specific number.

That's essentially three diplomatic summits' worth of time.

It's interesting that international reserves were calibrated to the length of a serious crisis, not a catastrophic one.

Octavio ES

Exacto.

Exactly.

Y lo que Mitsui hace al cruzar sin pagar es, en cierto modo, una señal: estamos aquí, seguimos navegando, no reconocemos vuestra autoridad sobre estas aguas, pero tampoco buscamos un conflicto.

And what Mitsui does by crossing without paying is, in a way, a signal: we're here, we keep sailing, we don't recognize your authority over these waters, but we're not looking for a conflict either.

Es la forma más silenciosa posible de decir algo importante.

It's the most silent possible way of saying something important.

Fletcher EN

Which is profoundly Japanese, in a way.

The art of making a position clear without making it a confrontation.

I've watched Japanese diplomats operate and there's a precision to their ambiguity that you don't see from many other countries.

Octavio ES

Y para los oyentes que quieren entender el mundo, este episodio de los barcos de Mitsui es una lección perfecta sobre cómo funciona la geopolítica real.

And for listeners who want to understand the world, this episode with Mitsui's ships is a perfect lesson in how real geopolitics works.

No son discursos y declaraciones.

It's not speeches and declarations.

Son decisiones concretas que se toman en el puente de un buque, en un despacho en Tokio, en silencio.

It's concrete decisions made on a ship's bridge, in an office in Tokyo, in silence.

Fletcher EN

And when those decisions accumulate, when enough ships cross without paying, or don't cross at all, that's when the economic pressure becomes visible.

That's when it lands in your electricity bill, your petrol price, the cost of a Toyota.

Octavio ES

Oye, Fletcher, antes de terminar, quiero preguntarte algo.

Hey, Fletcher, before we finish, I want to ask you something.

Antes dijiste que Mitsui afirmó que sus barcos no pagaron las tarifas.

Earlier you said Mitsui stated its ships didn't pay the fees.

Usé la expresión 'en cierto modo' un par de veces.

I used the phrase 'en cierto modo' a couple of times.

¿La entendiste bien?

Did you follow it properly?

Fletcher EN

I think so, 'in a certain way,' or maybe more naturally 'in a sense.' But the literal translation is a bit odd in English.

'In a certain manner' sounds almost Victorian.

Octavio ES

Sí, es una expresión muy útil en español porque suaviza lo que dices sin negarlo.

Yes, it's a very useful expression in Spanish because it softens what you're saying without denying it.

Si digo 'Japón, en cierto modo, sigue siendo vulnerable', no estoy diciendo que Japón sea completamente vulnerable ni que no lo sea.

If I say 'Japan, in a sense, is still vulnerable,' I'm not saying Japan is completely vulnerable or that it isn't.

Estoy matizando.

I'm adding nuance.

En español usamos estos moduladores constantemente para no sonar demasiado absolutos.

In Spanish we use these modulators constantly to avoid sounding too absolute.

Fletcher EN

We do something similar in English with 'in a way' or 'kind of,' but those can sound imprecise or even dismissive.

'In a sense' is probably the closest in formal English.

The Spanish version sounds more...

deliberate, somehow.

Less like you're hedging and more like you're being precise.

Octavio ES

Eso es porque en español, si dices algo sin matizar, la gente asume que eres arrogante o que no has pensado bien el tema.

That's because in Spanish, if you say something without nuance, people assume you're arrogant or that you haven't thought the matter through properly.

Los matizadores no son una debilidad, son una señal de inteligencia.

Qualifiers aren't a weakness, they're a sign of intelligence.

O eso nos decimos a nosotros mismos.

Or that's what we tell ourselves.

Fletcher EN

I'm filing that one away.

Next time I'm at a family dinner in Madrid and I say something catastrophically wrong, I'll just add 'en cierto modo' and hope for the best.
