So.
A bridge.
I want to start there, because I think the image of a bridge being destroyed tells you something that a missile strike on a military base doesn't.
Bueno, mira, es que no era un puente cualquiera.
Well, look, the thing is it wasn't just any bridge.
El B1 es, o era, el viaducto más alto de todo Oriente Medio.
The B1 is, or was, the highest viaduct in the entire Middle East.
Lo inauguraron hace apenas unos meses, en enero de este año.
They inaugurated it just a few months ago, in January of this year.
Era una obra de ingeniería de la que Irán estaba enormemente orgulloso.
It was an engineering project Iran was enormously proud of.
Inaugurated in January, destroyed in April.
That is brutal in a way that goes beyond the military calculation.
Eight people killed, ninety-five injured.
And the bridge linked Tehran to Karaj, which is a city of about two million people.
Exacto.
Exactly.
Karaj es la cuarta ciudad más grande de Irán.
Karaj is the fourth largest city in Iran.
El corredor entre Teherán y Karaj es una de las arterias más transitadas del país, tanto para el tráfico civil como para el movimiento de tropas y suministros militares.
The corridor between Tehran and Karaj is one of the most heavily trafficked arteries in the country, for both civilian traffic and the movement of troops and military supplies.
Esa ambigüedad es exactamente lo que hace que los puentes sean objetivos tan atractivos en la guerra moderna.
That ambiguity is precisely what makes bridges such attractive targets in modern war.
Right, and that ambiguity is also what makes them so morally complicated.
This wasn't a weapons depot.
This was a road that civilians used every single day.
La verdad es que el ataque a infraestructuras civiles tiene una historia militar larguísima, y en ella siempre aparece esa misma tensión.
The truth is that attacking civilian infrastructure has a very long military history, and that same tension always appears in it.
Los estrategas militares argumentan que cortar líneas de comunicación es legítimo.
Military strategists argue that cutting communication lines is legitimate.
Las víctimas civiles argumentan que eso es simplemente destruir su vida cotidiana.
Civilian victims argue that it simply means destroying their daily life.
Here's what gets me, though.
The technology angle on this is fascinating.
To hit the highest bridge in the Middle East, specifically, cleanly enough to bring it down, you need extraordinary precision.
This isn't carpet bombing.
This is something qualitatively different.
Sí, y ahí está el núcleo tecnológico de todo esto.
Yes, and that's the technological core of all this.
Las municiones guiadas de precisión, lo que los militares llaman PGMs, han transformado radicalmente la forma de atacar infraestructuras.
Precision-guided munitions, what the military calls PGMs, have radically transformed the way infrastructure is attacked.
Antes, para destruir un puente, necesitabas decenas o cientos de bombarderos.
Before, to destroy a bridge, you needed dozens or hundreds of bombers.
Ahora, con los sistemas de guía por GPS o por láser, puedes hacerlo con unos pocos misiles.
Now, with GPS or laser guidance systems, you can do it with just a few missiles.
I covered the Gulf War in ninety-one.
I was young, just getting started.
And the images of those precision strikes, the ones the Pentagon released, felt like science fiction.
A bomb going through a ventilation shaft.
Claro, pero lo que no mostraron en aquellas imágenes era la cantidad de veces que fallaban.
Of course, but what they didn't show in those images was how often they missed.
La precisión en 1991 era mucho menor de lo que el Pentágono quería hacernos creer.
The precision in 1991 was far less than the Pentagon wanted us to believe.
Los estudios posteriores mostraron que solo una fracción de las bombas lanzadas en esa guerra eran realmente guiadas, y que muchas de ellas fallaban el objetivo.
Subsequent studies showed that only a fraction of the bombs dropped in that war were actually guided, and many of those missed their targets.
The PR was ahead of the technology.
Which, honestly, is a very military institution thing to do.
Siempre.
Always.
Pero entre 1991 y ahora, la tecnología ha alcanzado y superado la propaganda.
But between 1991 and now, the technology has caught up with and surpassed the propaganda.
Los sistemas actuales, como las bombas JDAM o los misiles de crucero modernos, tienen una precisión de metros, no de kilómetros.
Current systems, like JDAM bombs or modern cruise missiles, have accuracy measured in meters, not kilometers.
Eso cambia fundamentalmente la naturaleza de lo que es posible atacar.
That fundamentally changes the nature of what it's possible to strike.
And JDAM, just to explain, is a kit.
You take a conventional dumb bomb and you bolt on a GPS guidance package.
It's relatively cheap, it's modular, and it turned the entire U.S.
and Israeli air arsenal into precision instruments almost overnight.
Exactamente.
Exactly.
Y lo extraordinario es que esa modularidad ha democratizado, si se puede usar esa palabra, la capacidad de destrucción precisa.
And the extraordinary thing is that this modularity has democratized, if you can use that word, the capacity for precise destruction.
Ya no hace falta desarrollar desde cero un misil de alta tecnología.
You no longer need to develop a high-tech missile from scratch.
Coges un artefacto que ya tienes, le añades el kit de guía, y de repente tienes una capacidad que antes solo estaba al alcance de las superpotencias.
You take an existing munition, add the guidance kit, and suddenly you have a capability that was previously only within reach of superpowers.
Which is almost a direct parallel to what drones have done on the other side of the ledger.
The technology that enables mass destruction has gotten dramatically cheaper and more accessible.
That cuts both ways.
Sí, sí, totalmente.
Yes, yes, totally.
A ver, hay una asimetría que vale la pena señalar.
Look, there's an asymmetry worth pointing out.
Israel y Estados Unidos usan esa precisión para destruir infraestructuras específicas.
Israel and the United States use that precision to destroy specific infrastructure.
Irán, por su parte, ha estado usando drones más baratos y misiles balísticos con menor precisión para atacar objetivos más amplios.
Iran, for its part, has been using cheaper drones and ballistic missiles with less precision to attack broader targets.
Son dos doctrinas tecnológicas distintas.
They're two distinct technological doctrines.
I want to go back to the bridge itself for a second, because I think the engineering story is actually remarkable.
The B1, by all accounts, was a genuine feat.
How tall are we talking?
Bueno, los datos exactos varían según la fuente, pero estamos hablando de un viaducto que superaba los doscientos metros en su punto más alto, cruzando un valle montañoso en la cordillera de Alborz, al norte de Teherán.
Well, the exact figures vary depending on the source, but we're talking about a viaduct that exceeded two hundred meters at its highest point, crossing a mountain valley in the Alborz mountain range, north of Tehran.
Era un proyecto de décadas de planificación, postergado repetidamente por sanciones internacionales que dificultaban el acceso a materiales y tecnología.
It was a project decades in the planning, repeatedly delayed by international sanctions that made access to materials and technology difficult.
So the sanctions are already in the story before a single bomb drops.
Iran couldn't build its own infrastructure at normal speed because of economic and technological isolation.
And then, when they finally finish it, it gets bombed in its fourth month of existence.
Es que eso es lo que hace que el ataque tenga una dimensión simbólica tan poderosa.
That's precisely what gives the attack such a powerful symbolic dimension.
No es solo cortar una carretera.
It's not just cutting a road.
Es destruir la demostración más visible de que Irán, a pesar del aislamiento, era capaz de hacer ingeniería de primer nivel.
It's destroying the most visible demonstration that Iran, despite its isolation, was capable of first-class engineering.
Eso tiene un valor propagandístico y psicológico enorme, en ambas direcciones.
That has enormous propaganda and psychological value, in both directions.
The extraordinary thing is how consistent this is with the history of infrastructure warfare.
Going all the way back to World War Two, the logic is the same.
You destroy not just the thing but the meaning of the thing.
Mira, los Aliados en la Segunda Guerra Mundial tenían toda una doctrina al respecto: la 'Transportation Plan', el plan de transportes.
Look, the Allies in World War Two had an entire doctrine around this: the Transportation Plan.
La idea era que si destruyes suficientes puentes, vías de tren y carreteras, el ejército enemigo se paraliza, no porque no tenga soldados o armas, sino porque no puede moverlos.
The idea was that if you destroy enough bridges, railway lines, and roads, the enemy army is paralyzed, not because it lacks soldiers or weapons, but because it can't move them.
Right, and Eisenhower and Churchill famously argued about that.
Churchill was worried about the French civilian casualties.
Eisenhower said the military logic was overwhelming.
That tension has never been resolved, it just gets relitigated in every war.
Y lo que ha cambiado con la tecnología moderna es que ese debate se vuelve más agudo, no menos.
And what has changed with modern technology is that this debate becomes more acute, not less.
Porque cuando tenías bombas imprecisas, podías argumentar que los daños colaterales eran inevitables.
Because when you had imprecise bombs, you could argue that collateral damage was unavoidable.
Cuando tienes misiles que pueden entrar por una ventana, la pregunta de a qué decides apuntar se vuelve mucho más difícil de eludir.
When you have missiles that can go through a window, the question of what you choose to aim at becomes much harder to dodge.
Look, there's a legal framework here too.
International humanitarian law, the laws of armed conflict, they distinguish between military objectives and civilian objects.
A bridge with dual use, military and civilian, falls into a grey zone that lawyers have been arguing about for decades.
Sí, el principio de proporcionalidad en el derecho internacional humanitario dice que el daño civil esperado no puede ser excesivo en relación con la ventaja militar prevista.
Yes, the principle of proportionality in international humanitarian law says that expected civilian harm cannot be excessive in relation to the anticipated military advantage.
Pero en la práctica, esa evaluación la hace el mismo ejército que lanza el ataque.
But in practice, that assessment is made by the same military that carries out the attack.
No hay un árbitro independiente en tiempo real.
There is no independent real-time arbiter.
Which is a polite way of saying those laws are almost entirely self-policed.
I spent enough time covering conflicts to know how that goes.
La verdad es que sí.
Honestly, yes.
Aunque también hay que decir que la tecnología de precisión ha reducido en términos absolutos el número de víctimas civiles en comparación con los bombardeos de área de la Segunda Guerra Mundial o incluso de Vietnam.
Although it's also worth saying that precision technology has reduced in absolute terms the number of civilian casualties compared to the area bombing of World War Two or even Vietnam.
No es que no importe.
It's not that it doesn't matter.
Es que el marco de comparación importa.
It's that the frame of comparison matters.
That's a fair point.
No, you're absolutely right about that.
The firebombing of Dresden killed more people in one night than this entire war has killed in weeks.
Which doesn't make eight deaths acceptable, but it does force you to hold two things at once.
A ver, y lo que viene a continuación es la pregunta más difícil de tecnología militar: si tienes la capacidad de destruir con tanta precisión, ¿qué te frena de hacerlo constantemente?
Well, and what comes next is the hardest question in military technology: if you have the capacity to destroy with such precision, what stops you from doing it constantly?
La respuesta histórica ha sido siempre una combinación de disuasión, represalia y derecho internacional.
The historical answer has always been a combination of deterrence, retaliation, and international law.
En este conflicto, esos frenos están claramente cediendo.
In this conflict, those restraints are clearly giving way.
Let's talk about what Iran has to do now.
Because rebuilding a bridge like this isn't just a civil engineering problem.
It's a technology problem, an economic problem, and a sanctions problem all rolled into one.
Mira, Irán ha construido infraestructuras importantes bajo sanciones durante décadas, lo cual es en sí mismo un logro técnico notable.
Look, Iran has built significant infrastructure under sanctions for decades, which is itself a remarkable technical achievement.
Han desarrollado ingeniería local en muchas áreas porque no tenían otra opción.
They've developed local engineering in many areas because they had no choice.
Pero hay componentes de alta tecnología, aceros especiales, software de diseño, sistemas de control, que siguen dependiendo del mercado internacional.
But there are high-tech components, special steels, design software, control systems, that still depend on the international market.
And that's where the strategy of targeting infrastructure intersects with the strategy of sanctions in a particularly cruel way.
You're not just destroying the thing.
You're making it maximally hard to rebuild.
Es que eso es una estrategia deliberada con un nombre en la literatura estratégica: se llama 'negación de capacidades'.
That is a deliberate strategy with a name in strategic literature: it's called 'capability denial.' You don't just destroy what the enemy has now, you attack their capacity to recover.
No solo destruyes lo que tiene el enemigo ahora, sino que atacas su capacidad de recuperarse.
It's what the Allies did to German synthetic fuel industry in 1944, and it's what's being done here.
Es lo que hicieron los Aliados con la industria alemana de combustible sintético en 1944, y es lo que se está haciendo aquí.
I mean, the parallel to the fuel industry attack is striking.
Albert Speer, Nazi Germany's armaments minister, said after the war that the synthetic fuel campaign was the thing that actually broke German war-making capacity.
Not the cities, the fuel.
Exacto.
Exactly.
Y la lección que los estrategas han sacado de esa historia es que no todos los objetivos de infraestructura son iguales.
And the lesson that strategists have drawn from that history is that not all infrastructure targets are equal.
Los hay que son sistémicos, cuya destrucción genera efectos en cadena que se propagan por toda la economía y el aparato militar.
Some are systemic, whose destruction generates cascading effects that spread throughout the economy and military apparatus.
Un puente entre dos ciudades grandes puede ser uno de ellos.
A bridge between two large cities can be one of them.
There's also the psychological dimension.
And I don't want to underestimate that.
When I was in Beirut in the nineties, the bridges were one of the first things that got rebuilt after the civil war.
Because a rebuilt bridge means something to people.
It means normal life is possible again.
Sí, y en el caso del B1 esa dimensión psicológica se multiplica porque el puente era reciente y era un símbolo de modernidad iraní.
Yes, and in the case of the B1 that psychological dimension is multiplied because the bridge was new and was a symbol of Iranian modernity.
Destruirlo es también un mensaje: tu capacidad tecnológica, tu progreso, tu orgullo de ingeniero, todo eso es vulnerable.
Destroying it is also a message: your technological capability, your progress, your engineering pride, all of that is vulnerable.
Eso está diseñado para afectar a la moral de una sociedad entera.
That is designed to affect the morale of an entire society.
So where does all of this leave us?
We have technology that can destroy with extraordinary precision.
We have international law that struggles to keep pace.
We have the deliberate targeting of civilian infrastructure that also has military value.
What does the next stage of this look like?
Bueno, la tendencia que veo es que la infraestructura digital y la física se están fusionando.
Well, the trend I see is that digital and physical infrastructure are merging.
Los puentes modernos, las redes eléctricas, los sistemas de agua, todo tiene ahora componentes de control digital.
Modern bridges, electrical grids, water systems, all of them now have digital control components.
Lo que significa que son vulnerables tanto a ataques físicos de precisión como a ciberataques.
Which means they are vulnerable to both precision physical attacks and cyberattacks.
Esa convergencia es el gran desafío tecnológico y estratégico de la próxima década.
That convergence is the great technological and strategic challenge of the next decade.
Right, so the next B1 doesn't even need a missile.
You could conceivably compromise the control systems of a bridge, a dam, a power grid, and create the same effect from a server room somewhere.
That is a genuinely terrifying thought.
Es que ya ha ocurrido.
It has already happened.
El ataque con Stuxnet contra las centrifugadoras nucleares iraníes en 2010 fue el primer caso documentado de un ciberataque que causó daño físico real a una infraestructura.
The Stuxnet attack on Iranian nuclear centrifuges in 2010 was the first documented case of a cyberattack causing real physical damage to infrastructure.
Y lo irónico, si quieres llamarlo así, es que el objetivo era Irán.
And the irony, if you want to call it that, is that the target was Iran.
Ahora Irán lleva años desarrollando sus propias capacidades cibernéticas ofensivas.
Now Iran has spent years developing its own offensive cyber capabilities.
Stuxnet is such a watershed moment.
And most people don't realize it was almost certainly a joint U.S.-Israeli operation.
So there's a direct line from Stuxnet in 2010 to missiles hitting an Iranian bridge in 2026.
The same partnership, different tools, same fundamental logic.
Y la gran pregunta sin respuesta es esta: ¿adónde va la escalada cuando casi toda la infraestructura crítica del mundo está conectada digitalmente y es vulnerable?
And the great unanswered question is this: where does escalation go when almost all of the world's critical infrastructure is digitally connected and vulnerable?
No hay ningún tratado internacional que regule el uso de armas cibernéticas con la misma claridad con que se regulan, siquiera en teoría, las armas convencionales.
There is no international treaty that regulates the use of cyber weapons with the same clarity as conventional weapons are regulated, even in theory.
Estamos construyendo la capacidad de destrucción antes de haber construido las normas que la limiten.
We are building the capacity for destruction before building the norms to limit it.
We built nuclear weapons and then spent forty years building the treaties, the hotlines, the doctrines of deterrence.
We built the internet and then fifteen years later started building the rules.
And now we're building precision strike technology and cyber weapons and the governance is, what, ten years behind?
Twenty?
Probablemente más.
Probably more.
Y mientras tanto, un puente que tardó décadas en construirse, que representaba una victoria técnica para millones de personas, deja de existir en cuestión de minutos.
And in the meantime, a bridge that took decades to build, that represented a technical victory for millions of people, ceases to exist in a matter of minutes.
Eso es lo que la tecnología de precisión ha hecho posible: la destrucción instantánea de lo que construir llevó generaciones.
That is what precision technology has made possible: the instant destruction of what took generations to build.
That's a sentence I'm going to be thinking about for a while.
The instant destruction of what took generations to build.
And the eight people who died on that bridge this week, they weren't abstractions in a strategic doctrine.
They were people crossing a road.
Eso es lo que nunca hay que perder de vista, por muy fascinante que sea el análisis tecnológico.
That is what we should never lose sight of, however fascinating the technological analysis may be.
Detrás de cada dato de precision guidance o de cada debate sobre proporcionalidad, hay personas que iban a trabajar, que volvían a casa, que cruzaban un puente en un día cualquiera y ya no están.
Behind every data point about precision guidance or every debate about proportionality, there are people going to work, coming home, crossing a bridge on an ordinary day and who are no longer here.
La tecnología nos da poder para olvidarnos de eso.
Technology gives us the power to forget that.
No deberíamos.
We shouldn't.
