A big mistake here was simply underestimating the scale of Iran. Iran has 90,000,000 people. More than 2x Ukraine. More than 2x Germany. More than 2x Iraq. More than any country in Europe. About 2/3 of Russia. Expecting to win a war on the cheap was a fantasy. Especially since Iran has been fighting Israel for years.

On the naval front, Ukraine sunk the Moskva with a few truck-mounted missiles. That finally made it undeniable that sending naval vessels anywhere near a hostile shore is a thing of the past. Countermeasures can take out some attacking missiles, but not all of them.

This is a real problem for the U.S. Navy, because they've invested heavily in craft intended to operate near hostile shores. Littoral combat ships and amphibious assault ships are intended to operate offshore of trouble spots. This worked a lot better when the trouble spots couldn't do much to them.

The size of Iran means that knocking out drone and missile production for long won't work. Russia has been trying to do that to Ukraine for years now. Ukraine produced 4 million drones last year, and production continues to increase. Ukraine even exports drones now. Saudi Arabia, Kuwait, and the UAE have been making deals with Ukraine for air defense systems. Iran exports drones to Russia.

Mass-produced drones today are a simple airframe, a lawnmower engine, and the smarts of a cell phone. Ukraine has people making them in basements. Presumably, so does Iran.

The US can't just pull out, either. The enemy gets a vote on when it's over. Israel, Iran, and Yemen now all have to agree. Probably the best deal the US can get at this point is a cease fire with Iran collecting tolls on the Strait of Hormuz.

Worst outcome is the US attacks Cuba, Cuba allies with Iran, it turns out that Cuba has been stocking up on Iranian drones, and Cuba becomes a forward base for drone and missile attacks on the southern US.

According to [0], in 2025 Iran had 86M people. Ukraine had 29M (~33%), Germany (highest in Europe) had 83M (~96%, uh?), Iraq had 46M (~53%), and Russia had 146M (~168% / ~59% reversed).

Wildly, wildly wrong about Germany but not too far off the rest[1].

[1] Although if you include Turkey in "Europe", "more than any country in Europe" droops a little because Turkey's 86092168 (99.456%) is basically identical to Iran's 86563000 when it comes to projection and estimation errors.

If this happens and Cuba decides to launch drones/missiles against the US homeland, it's not an exaggeration to say that Cuba is flattened and invaded that same afternoon. After 9/11, there's no world in which any attack on the US homeland, however small or local, is met with anything other than overwhelming retribution.

Having difficulty projecting force from the air with fighter bombers launched from air craft carriers and refueling caravans from the Indian Ocean or Mediterranean Sea against a determined enemy that has been preparing for this eventuality since 1979 is one thing. Being able to fly non-stop B-52 and B-2 sorties from home air bases with single-digit-hour flight times is a different thing entirely.

The big mistake was underestimating the appetite for rebellion despite 70%-80% wholesale opposition to the regime.[0] I personally know many, many Iranians who welcome the attacks along with their families. All of the high-profile assassinations involve intelligence from Iranians.

However, no one has guns, and government-backed militias roam the streets to maintain order.[1] There is no possibility of military coup. Many officers lives and livelihoods are at stake post-revolution, and they will go to great lengths to protect it. Remember, they killed 30K of their own to quell an uprising.[2] Surveillance is everywhere online and in person.[3] One spy in ten can ruin a revolutionary group. To make things worse, there is no unification around a leader or what should come next.

If anything, this war demonstrates the tyranny and tentacles of the modern state. The well seems forever poisoned once power is lost to despots.

> Iran has 90,000,000 people. More than 2x Ukraine

Population size is relevant but not the most important factor. Russia has 146,000,000, more than 4x than Ukraine. It doesn't guarantee that Russia will win the war.

> On the naval front, Ukraine sunk the Moskva with a few truck-mounted missiles.

Ukraine also had Bayraktar TB2 overhead which distracted Moskva's crew and provided targeting information. Russia probably didn't sent a fighter to down it because skies around Ukraine are contested. Skies not only around but over Iran are not reallty contested. Having said that Iran could sink an american ship if the navy will become complaicent and will assume there are no threats.

> The size of Iran means that knocking out drone and missile production for long won't work. Russia has been trying to do that to Ukraine for years now.

Russia cannot fly planes over Ukranian territory. The US can fly not only F-35 but even B-52. That's a big difference. The only thing which could prevent the US from knowking out missile and drone production is insufficient intellegence.

Germany has 80+ mil inhabitants. Also 90,000,000 people doesn't mean 90,000,000 soldiers, especially when a large part of them hate their own regime.
[−] LarsDu88 45d ago
Don't forget the coastal geography. Iran's coastline in the Persian gulf is longer than California's coastline, and they can do drone attacks anywhere in the Gulf, not just the narrow strait portion that everyone seems to focus on.

Cuba allying with Iran is pure fantasy though. There's no logistical connection between the two nations. It would be as irrelevant as Greenland allying with Antarctica.

> Countermeasures can take out some attacking missiles, but not all of them.

Exactly. On asymmetrical warfare, one side needs to get lucky all the time while the other only needs to get lucky once.

> Mass-produced drones today are a simple airframe, a lawnmower engine, and the smarts of a cell phone. Ukraine has people making them in basements. Presumably, so does Iran.

Their cheap and simple nature allows them to easily swarm targets and saturate their defenses. You can defend from a dozen incoming drones, but a hundred is significantly more difficult.

Also, consider the massive quadcopter shows in China as an example of how a well placed shipping container can swarm a target and make a devastating attack. Ukraine demonstrated one and disabled a significant part of the Russian bomber fleet.

> Worst outcome is the US attacks Cuba, Cuba allies with Iran, it turns out that Cuba has been stocking up on Iranian drones, and Cuba becomes a forward base for drone and missile attacks on the southern US.

Cuba would be foolish not to do that at the first opportunity, not to attack the US, but to neutralize any offensive from the US. Without a navy, a land invasion, or an effective blockade, is impossible.

Watch orange man pull that one out. There are no rules of behavior anymore, he can do whatever the fuck he wants, laws, treaties, morals, future and so on be damned, ego whims dominate the decision chain. Who is going to do anything. The only exception is israel, they seem to have a massive leverage on him and utilize it to the fullest.

Also he and his clan are heavily gaining from insider trading on those huge swings, we talk about billions here on just closest circle and everybody knows this. Also, US is gaining on big oil prices, another reason to sow more chaos. Not happy times ahead.

[−] hax0ron3 45d ago
I agree with some of your points, but I'm not sure about the drones. I don't think the kind of drone you can build with a lawnmower engine would be likely to do any significant damage to any but the smallest ship. And the US/Israel coalition has a much greater airpower advantage enabling them to target drone production than Russia does.

Cuba is in no shape to do anything. Even if they had drones, the leadership there is very unlikely to use them since doing so would result with almost 100% probability in the US killing or capturing them.

Sorry, irrelevant to what you‘re saying, but Germany has 85 mio inhabitants. You might mistake it for Poland.

This is a fairly well trod argument. It also requires a fairly long series of strawman arguments to come together. Yes, there are challenges, but ...

The reality of Hormuz was well known decades ago - even in 2002 Millenium exercise a bunch of speedboats and motorcycles stopped the US Navy from opening hormuz. [1]

Moskva was taken down by a well coordinated strike that distracted its one (1!) fire control radar. It was also alone. Those are important factors. [2]

A blanket comparison of Russia's attempts to eliminate Ukraine's industry with US Navy's ability to eliminate Iran's is ... questionable. We've flown 1000s of uncontested sorties over Ukraine, and Russia has been relegated to knocking down apartment buildings with Iran's own drones.

It is entirely possible that the US Navy is commanded by myopic idiots who fall for those tricks, but I doubt it.

Finally, it's not entirely clear that the large population won't, itself, become at least partially an asset of the resistance.

The ships the LCS are intended to replace are significantly more capable at absorbing damage from this type of threat. If you are willing to go up to destroyer class, you are probably approaching immunity for this scenario.

> Former CIA intelligence officer Robert Finke said the blast appeared to be caused by C4 explosives molded into a shaped charge against the hull of the boat.[6] More than 1,000 pounds (450 kg) of explosive were used.[7] Much of the blast entered a mechanical space below the ship's galley, violently pushing up the deck, thereby killing crew members who were lining up for lunch.[8] The crew fought flooding in the engineering spaces and had the damage under control after three days. Divers inspected the hull and determined that the keel had not been damaged.

The global Shia’s population is even larger than Russia’s population, and more willing to fight the US/Israel. Russia is of course superior to Iran technologically but Iran has the larger support worldwide.

Underestimation requires estimation. There was no thought put into the decision to start this war. These are people who have thoroughly bought into their own propaganda. Can the US win a war against Iran? The answer is “America, fuck yeah.” They think we’re omnipotent and literally favored by their god. They think the reason we’ve had military problems in the past is because lefty bedwetters insist on stupid rules like “no bombing schools.” You’ve put more thought into this operation in this comment than our top leadership has.
[−] chadash 45d ago
I’m not sure I agree with your argument but all of it made sense until you started talking about Cuba.

Iran knows that the US population really really doesn’t want a ground invasion. Right now, we have lost a handful of lives from missiles hitting US bases, but it’s not the same as a ground war.

Cuba, however, would very much get a ground invasion if they start striking the US with missiles. It’s not even a question. And I also assume their leaders are not religious fanatics with any interest in martyrdom.

Is that really true? Just claim that Iran's Nuclear ambitions have been destroyed, and anyone who needs oil can "Buy it from the US or get it themselves from Hormuz" - mission accomplished!

With the US withdrawing (or atleast not attacking), Iran can stop the drone attacks and open Hormuz - collecting fees from passing ships, call it reparations and a win!

I like the size and population take, but the industry perspective is bad: Russia doesn't have air superiority. US and Israel do. Cuba becoming a base for Shaed drones? You are out of touch with how much industry you need for that. They are cheap, but they are not FPVs or off-the-shelf Mavics.

I think you're missing the point.

I am sure Israel did not underestimate the scale of Iran.

That is why Netanyahu dedicated 40 years of his life to the famous "40 years 2-weeks away from a bomb" one-man stand-up comedy show when visiting the US or the UN.

For 40 years Netanyahu waited for a stupid enough President to take a seat in the Oval Office.

For 40 years, consecutive US presidents asked their advisors before going back to Netanyahu with a polite but firm "Thanks, but no thanks".

Then along came the Donny.

Advisors ? What advisors ?

Cabinet of yes-men ? Yes please !

It's a great sign for the US military as a whole: That is the primary American tactic to defeat China, using land forces hidden on the First Island Chain with anti-ship missiles, to control the seas around China. More here:

In chapter 11 of All Quiet on the Western Front Paul and his unit find an abandoned food cache in the middle of no mans land. Instead of secreting away the food back to their lines where they will have to share it, they decide to just cook and eat it right then and there. But a spotter plane from the allies sees the smoke and then begins shelling their position. Cue a terrifying, if hilarious, scene where the soldiers try and cook pancakes as shells explode around them. Paul, as the last to leave, takes his pancakes on a plate and dashes out, timing his escape between bursts, and just barely making it back to the German trenches. Its a rare comic scene in an otherwise horrific and very real look at WW1.

The scene in the book is just so familiar to the lines in Ukraine these days, nearly a hundred years later. Instead of spotter planes near the dawn of aviation, we have satellites and drones (similarly quite new in the role). Instead of just shells and fuzing experts, we have FPV drones and much more sophisticated shells. Instead of buddies from the same towns all huddled together in cold muddy holes, we have deracinated units spread far and wide in laying in fear of thermal imaging. This results in a no mans land again, but a dozen kilometers wide instead of a few hundred meters wide, and somehow more psychologically damaging.

My point is that absent any tech that will miraculously be invented and deployed widely in the new few weeks, the Iran war, if it should be a ground one, is going to be just like Ukraine is today, which is somehow a worse version of trench warfare.

Even casual Victoria II players know that WW1 is essentially the final boss of the game. And the 'lesson' of Vicky II is essentialy: Do not fight WW1, it ruins Everything.

To be clear: The US is choosing to fight a worse version of WW1 without even a stated (or likely even known) condition of victory. We're about to send many thousands boys to suffer and die for not 'literally nothing', but actually literally nothing.

>The era of carrier-dominated airpower is fading, as cheap, unmanned anti-ship weapons reshape naval warfare, whether US planners are ready for it or not.

is not really backed up by reality. Pretty much the whole US operation so far, destroying much of Iran's military and leadership was done from US carriers. If anything it demonstrates how powerful they are.

Also straits being closed to shipping by whatever power controls the shores is not a new thing. The Bosphophorous has been closed on and off by the Ottomans or Turks since 1453 and the allies couldn't break through in WW1. They can send raiding ships, use canons, artillery, naval mines etc. You don't need the new tech.

[−] dundarious 45d ago
Trita Parsi of RS had been saying weeks in advance that the Iranians would retaliate against gulf states collaborating with/supporting the US & Israel, would close the Strait of Hormuz, and would continue fighting until it established a pain threshold had been reached and acknowledged by its enemies, in order to prevent yet more "short wars". Iran's previous retaliations that were well choreographed and coordinated in advance with US & Israel would not be repeated. He was not alone in saying this, but he was one of the most prominent, connected, and learned people saying so.

Much of the administration and news media are only catching up to all of this long after the fact. Many still cling to the idea that this was unforeseen, or irrational on the part of the Iranians.

[−] kashunstva 46d ago
Whether or not professional military strategists and planners anticipated this shift in carrier-based projection of power in the era of low-cost drones, it is nearly certain that the Commander-in-Chief of the United States military has not. And if the Commander is involved in the either the day-to-day operations or the strategic level of planning, I can’t imagine that whatever reasoning about these shifts in power dynamics has taken place will influence U.S. operations.

“during WWII, the US Navy… winning the U-boat war in the Atlantic”

Sounds like typical US revisionist history.

They developed ASDIC? HF/DF? Hedgehog? Even the depth charge?

No, that was all the British.

I would say technological development plus the Enigma decrypts were the biggest factor.

[−] woeirua 45d ago
This gives drones way too much credit. The USN knew that Iran could block the strait of Hormuz back in the 80s. Anti-ship missiles were already effective and plentiful enough to do it then and they’ve only gotten more lethal since. The long term solution here is to build pipelines that eliminate the need to sail up the strait. Why this wasn’t done already is beyond me.
[−] mmooss 45d ago
The United States primary strategy against China, in the event of war around Taiwan or nearby, is the same:

China's coast is mostly enclosed by the 'First Island Chain', which extends from Japan to Taiwan, through the Philippines and Borneo (look up a map and the situation will be very clear). Imagine strings of islands along the US coasts controlled by Chinese allies and with Chinese and allied forces training intensively there.

The American plan is to keep the Chinese navy trapped (or under assault) along its own coast by putting Marines (and Army soldiers too, I think) on the islands with anti-ship missiles.

The northern tip of the Philippines is as close to Taiwan as the Chinese mainland is; the US and Philippines are conducting an essentially endless series of military exercises and the US is placing some of its most advanced missiles there.

You can't. Iran only needs to be credible in their threats to make crossing the strait too risky. And for that you only need a few missiles, drones and mines every so often.

Asymetric warfare is a hell of a hole to dig oneself into, ain't it?

[−] fooker 46d ago
At the heart of this is the fact that America has lost the capability to manufacture anything at scale.

High tech interceptors and missiles and aircraft carriers are great, but with China's help these are outnumbered by three (soon to be four) orders of magnitude.

It's unclear if we can do much other than threaten sanctions and nukes, with not much in between.

Irrespective of the political leadership, it's unlikely that USA military is completely oblivious about the new modes of wars - cheap drones, AI, rapid build-outs (e.g. in China). On the contrary, they are likely deeply aware of it. That being said, it is also likely true that USA has become more bureaucratic and there is a high chance of deer-in-headlights situation. USA remains the shining city on the hill, though probably not for long, unless we pull up socks and innovate, work, work, work and build, build and build.

Not every war can be fought from air, there needs to be soldiers on the ground.

In fight against ISIS, the Iraqi amry, Shia Militias, Kurds and others were ground forces while Allies were in Air. In Afghanistan & Gulf War, US forces were on ground.

But in these "conflict", no party is ready to send ground forces, ground forces to stop the air drones, ship drones etc. So the "blockade" will probably continue.

In the movie Thirteen Days, JFK mentions a book titled March of Folly by Barbara Tuchmann. I bought the book on that tip and it has an interesting chapter on Vietnam. I don't think adding a chapter on this "special operation" would even be worth it as it would just be repetitive.

Iran's deep investment in asymmetric warfare is paying serious dividends. You wouldn't expect a nation that's being bombed day and night, essentially at will, to still hold so many cards. Not only is the US completely incapable of strong-arming the straight open, but the rate of missile and drone attacks out of Iran and its proxies has been accelerating the last few days, as has the rate of successful hits.

The title should change 'won't' to 'shouldn't'. This administration doesn't do things because of deep understanding, it does them because of gut reaction. The US Military could, at an unknown cost, just blast away.

This article points out, rightfully, how scared we are to put our weapons in harms way because of how expensive they are. I made this argument many times to friends years ago. From a military strategic point of view we should be developing drone/cruise missile carriers (and upping our SSGN capabilities) and abandoning the carrier navy. They are only good for show at port visits and turn useful ships like DDGs into escorts instead of front line assets.

That being said, from a diplomatic strategic point of view, I really like a useless navy full of ships that are good for port visits and not real wars. If you build ships good for real wars you tend to get into wars. If you build ships good for visiting other countries you tend not to go to war with those countries.

[−] LAC-Tech 45d ago
I maintain hope that the US will declare some arbitrary victory condition "Iran's capacity to do XYZ has been critically degraded!" and will unilaterally disengage.

Unfortunately this will almost definitely occur after Israel has included it's invasion of Lebanon and annexed more territory, which is what this whole war seems to be a cover for.

[−] bradley13 45d ago
Cheap airborne weapons have irreversibly changed warfare. IIRC a Patriot missile costs something like $4 million. Using them to shoot down $50k Shahed drone is a losing proposition. That's not only because of the price, but because the drones can be produced a lot faster. Even Iran's ballistic missiles are a lot cheaper and faster to produce than any defense system that can reliably destroy them.
[−] steveBK123 45d ago
The problem is that we need to adapt to the asymmetrical aspect of drone warfare, as Ukraine has done. The best description I saw of the current state is “flying IEDs”.

Drones and ballistic missiles make area denial asymmetrically cheap for a defending forces. This lesson needs to be incorporated because it would be the same tactic used by China to deny access to the South China Sea.

[−] V__ 46d ago
The U.S. can't win this war. John Kiriakou did a nice analysis on this on his recent podcasts. "Iran just has to prolong the war and survive it to win". Trump on the other hand needs a decisive win fast, or the economic and political fallout will be too big. As long as Iran can launch cheap drones and keep a small but steady pressure there is just no path out of this for the U.S. except to go home.

Must be nice for western arm chair commentators to discuss this without once feeling the consequences of the actions of their elected government.

Where I live - we face a severe shortage of LPG fuel due to this. Quite a few restaurants have shut down temporarily. Migrant workers around the parts who have no access to a kitchen because they live in tiny quarters with a bedding and a common toilet are struggling to find sustainable food. Acquaintances who own workshop are running around trying to figure out food arrangements for their employees. And we are not even party to this shitty war!

We are making do with electric alternatives but thats also because we are in the top 5%. Our household staff are struggling to figure out the situation. Induction gas stoves are either stocked our or selling for 3-4x their regular price. Even if they get access to one - electric supply is unreliable and they are not sure how to pay the bill. Electricity usage is subsidized (its free upto 200 Kwh / month) but if it exceeds that they will have to pay full price which hurts their budget quite a lot.
