    US Router Ban

    07/04/2026 | 12 mins.
    This week we talk about modems, WiFi, and kinda sorta bribes.
    We also discuss Huawei, government subsidies, and the FCC.
    Recommended Book: Replaceable You by Mary Roach
    Transcript
    Many homes, those with WiFi connections to the internet, have two different devices they use to make that connectivity happen.
    The first is a modem, which is what connects directly to your internet service provider, often via an ethernet jack in the wall that connects to a series of cables webbed throughout your city.
    The second is a router, which plugs into the modem and then spreads that signal, derived from that network of city-wide cables around your home, either by splitting that single ethernet jack into multiple ethernet jacks, allowing multiple devices to plug into that network, or by creating a wireless signal, WiFi, that multiple devices can connect to wirelessly in the same way. Many routers will have both options, though in most homes and for most modern devices, WiFi tends to be the more common access point because of its convenience, these days.
    That WiFi signal, and the connection provided via those additional ethernet ports on the router, create what’s called a Local Area Network of devices, or LAN. This local area network allow these devices—your phone and your laptop, for instance—to connect to each other directly, but its primary role for most people is using that connection to the modem to grant these devices access the wider internet.
    In addition to providing that internet access and creating the Local Area Network, connecting devices on that network to each other, routers also usually provide a layer of security to those devices. This can be done via firewalls and with encryption, which is important as unprotected networks can leave the devices plugged into them vulnerable to outside attack. That means if the router is breached or in some other way exploited, a whole company’s worth of computers, or all your local devices at home, could be made part of a botnet, could be held hostage by ransomware, or could be keylogged until you provide login information for your banks or other seemingly secure accounts to whomever broke into that insufficiently protected LAN.
    What I’d like to talk about today is a recently announced ban on some types of routers in the US, the reasoning behind this ban, and what might happen next.

    On March 23, 2026, the US Federal Communications Commission announced a ban on the import of all new consumer-grade routers not made in the United States.
    This ban does not impact routers that are already on the market and in homes, so if you have one already, you’re fine. And if you’re buying an existing model, that should be fine, too.
    It will apply to new routers, though, and the rationale provided by the FCC with the announcement is that imported routers are a “severe cybersecurity risk that could be leveraged to immediately and severely disrupt US critical infrastructure.”
    They also cited recent, major hacks like Salt Typhoon, saying that routers brought into the US provided a means of entry for some components of those attacks.
    This stated concern is similar to the one that was at the center of the Trump administration’s 2019 ban of products made by Chinese tech company Huawei in the United States. Huawei made, and still makes, all kinds of products, including consumer-grade smartphones, and high-end 5G equipment sold to telecommunications companies around the world for use in their infrastructure.
    The concern was that a company like Huawei might leverage its far better prices, which were partly possible because of backing from the Chinese government, to put foreign competitors out of business. From there, they could dominate these industries, while also getting their equipment deep in the telecommunications infrastructure of the US and US allies. Then, it would be relatively easy to insert spy equipment and eavesdrop on phone calls and data transmissions from phones, or to incorporate kill-switches into these grids, so if China ever needed to, for instance, distract the US and its allies while they invaded Taiwan, they could just push a button, kill the US telecommunications grid, and that would buy them some time and fog of war to do what they wanted to do without immediate repercussions; and undoing a successful invasion would be a million times more difficult than stepping in while it’s happening to prevent it.
    As of 2024, Huawei still controlled about a third of the global 5G market. It controlled about 27.5% back in 2019, the year it was banned in the US and in many US allied nations, so while it’s possible they could have grown even bigger than that had the ban not been implemented, they still grew following its implementation.
    Chinese companies currently control about 60% of the US router market, and it’s likely the local, US market will shift, reorienting toward US makers over the next decade or so. But it’s possible these Chinese companies will grow their global footprint even further, as previous US bans have pushed them into different, less exploited markets, and that’s resulted in a wider footprint for such companies, even if their profits may drop a little after leaving the spendier US market.
    There’s also a pretty good chance we’ll see deals to move more manufacturing to the US, which could allow some of these companies to make relatively small changes to their operations in order to bypass the ban entirely.
    This seems extremely likely, at least in the short term, as all major players in the US router market fall under the FCC’s definition of not being entirely US owned and operated, and making consumer-grade routers that are designed or manufactured outside the US. Even the ostensibly more US companies, based and founded here, make their stuff primarily in Southeast Asia; so even those companies would seem to fall afoul of this new rule.
    The FCC has also given these companies the opportunity to apply for what’s called Conditional Approval from the Department of Defense and Department of Homeland Security, which would require they give a bunch of details about their company and products to these entities, along with plans to manufacture more stuff in the US, and these departments can then give them permission to keep selling in the meantime.
    It’s worth mentioning here that this kind of set up has previously given foreign entities a chance to funnel money into President Trump’s properties and businesses, before then speaking with him or one of his representatives and coming to some kind of agreement, the President then instructing the relevant agencies or departments to let those companies through, the ban not applying to them or not applying in the same way.
    There are concerns that such bans basically operate as requests for bribes, in other words, and those who don’t pay up see their customer base dwindle in the US market, while those who do get away with a slap on the wrist so long as they promise to make more stuff in the US at some point—though they’re not really held to that promise in any concrete way, and often that’s where their efforts stop, at the announcement of such changes.
    Also worth mentioning is that it’s not clear why this applies only to consumer-grade routers, as it would seem like the industrial- and military-grade ones would be of even greater concern, at least based on the claims made by the FCC when announcing this ban.
    We also don’t know why it’s being applied to new models, but not models currently being sold, and not those already in our homes; all of which would seem to be just as vulnerable as newer models that haven’t made it to the market yet.
    There’s a chance those details will follow, and there’s also a chance, again, that this is more about the administration maybe accumulating promises from foreign companies to move manufacturing to the US, because that looks good in an election year, and it’s maybe another means of accumulating bribes from companies that would find it far cheaper to make contributions to organizations the President either controls or favors, than to build new manufacturing capacity in the US, or leave the market entirely.

    Ukraine and Iran

    31/03/2026 | 12 mins.
    This week we talk about cheap drones, energy resources, and Russia’s invasion of Ukraine.
    We also discuss the Strait of Hormuz, the war in Iran, and economic asymmetry.
    Recommended Book: The Age of Extraction by Tim Wu
    Transcript
    Russia’s invasion of Ukraine has been pretty universally bad for everyone involved, very much including Russia, which going into the fifth year of this conflict, which it started by massing troops on its neighbor’s border and invading, unprovoked, following years of funding asymmetric military incursions in Ukraine’s southeast. Following their full invasion though, Russia has reportedly suffered around 1.25 million casualties, with more than 400,000 of those casualties suffered in 2025, alone. It’s estimated that Russia has also suffered at least 325,000 deaths, and Ukrainian officials reported confirmed kills of more than 30,000 Russian soldiers just in January 2026.
    As of early 2026, Russian controlled about 20% of Ukraine, down from the height of its occupation, back in March of 2022, when it controlled 26% of the country.
    And due to a combination of military spending, intense and expansive international sanctions, and damage inflicted by Ukraine, it’s estimated that Russia has incurred about $1 trillion in damages, about a fifth of that being direct operational expenses, and around a fourth the result of reduced growth and lost assets stemming from all those sanctions.
    There’s a good chance that all of these numbers, aside from the land controlled, are undercounts, too, as some estimates rely on official figures, and those figures are generally assumed to be partially fabricated to allow Russia to keep face in what is already a pretty humiliating situation—a war they started and which they thought would be a walk in the park, lasting maybe a week, but which has instead gone on to reshape their entire country and present one of the biggest threats to Putin’s control over the Kremlin since he took office.
    That in mind, a report from last week, at the tail-end of March, suggests that the Kremlin knows things aren’t looking great for them, and they asked Russian oligarchs to donate money to the cause, to help stabilize Russian finances. This report, which is unconfirmed, but has been reported by multiple Russian media entities, arrives at a moment in which the Russian government is also planning cuts to all sorts of spending, including military spending, but also a reported 10% across the board, to all “non-sensitive” matters in its 2026 budget.
    Despite these fairly abysmal figures, though, there’s some optimism in Russia-supporting circles right now, in large part because the conflict in Iran, and Iran’s near shutting down of the Strait of Hormuz, which is an important channel for the flow of international energy assets, that’s goosed the price of oil and gas, which in turn has goosed Russian income substantially.
    What I’d like to talk about today are the interconnections between the conflict in Ukraine and the conflict in Iran, and how Ukraine being invaded seems to have put them in a position of relative influence and authority in this new conflict in the Middle East.

    From the moment Russia launched its full-scale invasion of Ukraine, the Ukrainian military, and its government, industrial base, and pretty much everyone else, scrambled to find an asymmetric means of keeping a far larger, wealthier, and ostensibly more experienced and better backed foe from just steam-rolling over them.
    They found that by leveraging lower-cost deterrents, like cheap rockets and drones, they could pay something like $10,000 to take out a tank or other weapons platform that cost Russia a million or ten million dollars. That’s a pretty stellar trade-off, and if you can do that over and over again, eventually you make the cost of the conflict just ridiculously unbalanced, each trade of hardware costing you very little and them a whole lot, which with time can making waging war unsustainable for the side paying orders of magnitudes more.
    Russia is of course making use of inexpensive drones and rockets, as well. That’s become a norm in modern conflicts, especially over the past five years or so, as cheap but capable and easy to produce models have started rolling of manufacturing lines in Iran and Turkey, allowing them to become popular sources of single-use but quite agile and deadly aerial weaponry.
    Ukraine has gone further than most other entities, though, as they’re immensely incentivized to get this right, and to put their full support behind anything that gives them the upper-hand against what’s still a powerful and otherwise overwhelming invading force. And this patchwork of companies, independent and government supported, large-ish and tiny enough to operate under constant fire and in wartime conditions, has since scaled-up so that they’re expected to manufacture about 7 million drones of many different varieties in 2026.
    This scaling has attracted a lot of outside investment, and Ukraine is now considered to be not just a bulwark against current Russian aggression in Europe, taking the brunt of the damage so that Russia isn’t able to turn its attention to the Baltic states and other potential, future targets. It’s also considered to be a vital resource for future protection against Russia, as the US has become a less reliable ally, and NATO, which until recently has been mostly funded and armed by the US, is still getting its legs under it, more members contributing both money and other resources, but possibly not fast enough.
    If Russia were to either win in Ukraine and then turn its full-tilt military machine further west, toward other parts of Europe, or if it were to come to some kind of stalemate or peace agreement in Ukraine and then do the same, many leaders throughout Europe believe that Ukrainians, grizzled and scar from this current invasion, will be the ones to train up comparably inexperienced NATO and European Union forces, and to provide the best new, asymmetry-focused military hardware, like drones of all shapes and sizes, as well.
    They’ll be not just the arsenal of NATO and the EU, they’ll also probably be the training officers and commanders.
    We already see evidence of this probable future demand for Ukrainian goods and services in Gulf states that were attacked by Iran shortly after Israel and the US launched their own attacks that killed Iran’s leader and caused a great deal of damage throughout the country.
    Five Iranian neighbors have reportedly made deals with Ukraine to help them defend against future attacks from Iran, especially drone and missile attacks against their energy and water infrastructure.
    This help comes in the form of Ukrainian technology, which has been forged by their war, defending against Russia’s incursion, but also training by Ukrainian experts, who are a lot more informed by those war-time realities, and know how to keep infrastructure safe while at the same time taking out the enemy’s capacity to attack in the future.
    Ukraine’s hardware is also super cheap compared to comparable alternatives. Ukraine can produce a long-range strike drone for about $200,000, compared to similar drones made by companies in other western countries that cost between $5-10 million. Ukrainian companies also produce far cheaper anti-personnel drones, and interceptor drones and rockets that can flip the cost considerations in some types of conflict.
    Often the attacker will launch a bunch of multi-million dollar rockets, alongside a bunch of $10,000 decoys. If your anti-rocket interceptors hit the decoys, and your interceptors cost more than those decoys, maybe a few million dollars apiece, you very quickly end up spending more than your attacker. Reducing the cost of those defensive materials, then, can give the defender the cost advantage, which makes holding out over the long-haul, but also producing enough interceptors to prevent infrastructure damage and save lives, more financially feasible.
    There’s a strange interconnectedness between these two conflicts, then, as Russia’s invasion of Ukraine has turned Ukraine into a military product and services powerhouse that’s only just now beginning to scale up, but already in high-demand, while at the same time, Iran’s actions in the Strait of Hormuz, cutting off energy product flow through this vital channel, is boosting Russia’s income dramatically at a moment in which it desperately needs that income to keep invading Ukraine.
    That influx of resources could help Russia maintain its invasion for longer than they could otherwise manage, and it could give them a leg up, an even bigger advantage than they already have, which in turn could force Ukraine to become even more skillful and experienced, even better at what they do, leading to even better weapons and tactics that they then share with clients and allies in the Middle East for use against Iran.

    Cuban Oil Blockade

    24/03/2026 | 14 mins.
    This week we talk about the Cold War, the Cuban Missile Crisis, and decapitation attacks.
    We also discuss Venezuela, Iran, and the Platt Amendment.
    Recommended Book: The Will of the Many by James Islington
    Transcript
    Cuba is a large island nation, about the same size as the US state of Tennessee, which formally gained its independence from Spain in late 1898, following three wars of independence, the last of which brought the US, Puerto Rico, and the Philippines into play against the Spanish when the Spanish military sunk the USS Maine in Havana Harbor, triggering the Spanish-American War.
    That conflict, which Spain lost, led to the US’s acquisition of Puerto Rico, Guam, and the Philippines, and it led to a piece of US legislation called the Platt Amendment, which redefined the relationship between the US and Cuba, following the war, making Cuba a protectorate of the United States, the US promising to leave, withdrawing its troops from Cuban soil, only if seven conditions were met, and an additional provision that Cuba sign a treaty indicating they would continue to adhere to these conditions moving forward—making them permanent.
    Most of these conditions relate to Cuba’s ability to enter into relationships with other nations, but provision three also says the US can intervene if doing so will preserve Cuban independence, and that Cuba will sell or lease to the US the land it needs to base its naval vessels in the area, so that it can intervene, militarily if necessary, to keep Cuba independent.
    The other provisions are largely related to ensuring Cuba stays financially solvent and clean, the former meant to help maintain that independence, so Cuba doesn’t make deals with other nations, perhaps US enemies, in order to bail itself out when financially in trouble, and the latter meant to help prevent the bubbling up of diseases in a not well-maintained Cuba, that might then spread to the US.
    These concerns were concerns for the US government because Cuba is very, very close to the US. It’s just over 90 miles away from Key West, Florida, and that means in the mind of those tasked with defending the US against foreign incursion, Cuba has long represented an uncontrolled variable where enemies could conceivably base all sorts of military assets, including but not limited to nuclear weapons.
    That makes Cuba, again, in the minds of defense strategists looking to help the US secure its borders, long-term, something like an aircraft carrier slash nuclear submarine the size of Tennessee, located so close to the US that it could take out all sorts of major assets in a flash, long before the US could respond, getting the same sorts of strike craft and missiles to the Soviet Union.
    This framing of the situation, and this collection of concerns, is what led to the Cuban Missile Crisis back in 1962, when the US deployed nuclear weapons in the UK, Italy, and Turkey, all of which were closer to major Soviet hubs than the US, and that led to a tit-for-tat move by the Soviets to deploy nuclear missiles to Cuba, both to get their own weapons closer to the US, just as the US did to them with those new deployments, but also to deter a potential US invasion of Cuba, which was a staunch ally of the Soviet Union.
    The crisis lasted 13 days, and though then US President Kennedy was advised to launch an air strike against Soviet missile supplies, and to then invade the Cuban mainland to prevent the basing of Soviet nuclear weapons there, he instead opted for a naval blockade of Cuba, hoping to keep more missile supplies from arriving, and to thus avoid a strike on a Soviet ally that could accidentally spark a shooting war.
    After this nearly two-week standoff, the US and Soviet leaders agreed that the Soviets would dismantle the offensive weapons they were building in Cuba in exchange for a public declaration by the US to not invade Cuba. The US also secretly pledged to dismantle its own offensive weapons that it had recently deployed to Italy and Turkey, and the weapons they deployed to the UK were also disbanded the following year.
    This sequence of events is generally seen as a minor victory for the US during an especially fraught portion of the Cold War, as that secret agreement between Kennedy and Soviet leader Khrushchev meant that the Soviet people and leadership perceived this agreement as an embarrassing loss, and an example of Soviet weakness on the international stage—they blinked and the US got what they wanted without giving much of anything, though of course, again, the US gave a fair bit too, just in secret.
    What I’d like to talk about today is a recent escalation in the US’s posture toward Cuba, and what might happen next, as a result of that change.

    In early January 2026, the US military, ostensibly as part of a larger effort aimed at disrupting a network of watercraft that carry drugs from mostly South and Central American drugmakers across the border, into US markets, called Operation Southern Spear, the United States implemented a new blockade aimed at sanctioned oil tankers carrying fuel from Venezuela to, among other destinations, Cuban ports.
    Shortly before this blockade was declared, the US seized an oil tanker off the coast of Venezuela, then harassed, boarded, and intimidated other tankers, including one from Russia, that were also dealing in Venezuelan oil—something that US sanctions disallowed, and which the Trump administration had decided to focus on, ostensibly as part of that anti-drug effort, but also seemingly as part of a then-impending mission to kidnap Venezuelan President Maduro, who was then secreted away to the US to face trial, which is where he is, today.
    These seizures hit Cuba especially hard because the country is highly reliant on all sorts of imports, much of its income derived from tourism, not manufacturing or raw materials, and fuel coming from Venezuela was especially vital—about 72% of Cuba’s electricity generation comes from oil-fueled power plants, and basically its entire transportation section is reliant on the same.
    Venezuela under Maduro also provided oil to Cuba at a discount, subsidizing it because those US sanctions didn’t allow Venezuela to have many other reliable customers, and because the authoritarian governments of these two nations saw each other as fellow-travelers in the region, and thus wanted to keep each other propped up against constant pressure from the US and other democracies in the Americas.
    As of March 2026, Cuba has gone without crude oil deliveries for three months, and this has led to waves of flight cancellations and a depletion of tourism, which again, is the country’s most vital income source. As of mid-March, Cuba’s energy grid has also collapsed, which has left about 10 million people without power most of the time, amplifying existing problems caused by the country’s antiquated energy generation and distribution systems.
    All of which seems to be according to plan for the second US Trump administration, which announced, as far back as January of this year, that it was seeking regime change in Cuba, and these blackouts have triggered exceedingly rare violent protests against that regime by Cuban citizens; these protests haven’t led to any real change or consequences yet, but they could, with time.
    For their part, the Cuban government has said they’ve entered diplomatic talks with the US, and they’ve already agreed to release 51 political prisoners, just as an up-front, good will gesture. But they’ve also said changes to the Cuban political system or government—which is an authoritarian regime with absolute power, and which, like most such regimes, is openly corrupt, those in charge enriching themselves at the expense of everyone else, while keeping control via state-sanctioned violence against its own citizens—they’ve said changing that is non-negotiable, also noting that if there is direct aggression against Cuba by the US, they’ll fight and offer up “impenetrable resistance.’
    The change that the US government seeks is reportedly similar to what was accomplished in Venezuela: booting the current leader, but keeping the existing regime, the power behind the publicly visible throne, intact, and then the US government influencing that existing regime from afar.
    This deviates from the assumed model, attempted by previous US and other governments throughout history, to boot the leaders of opposing government types and then replace them, and the local system, with something closer to their own. This new approach is possibly what the Trump administration is aiming for in Iran, as well, though it’s difficult to say how well the model will work even in Venezuela, where it’s still early days after the US’s seemingly successful decapitation attack, much less in places like Cuba, where there’s no single central power in the public-facing government, much of that power spread between Communist Party leaders, rather than hoarded by a single individual—a far cry from how things were under Castro during the Cold War.
    As of the day I’m recording this, there’s a new wrinkle in this blockade: a Russian oil tanker has been tracked heading along a trajectory that would seem to lead to Cuba, which, if accurate, could put the US and Russia at odds over deliveries to the island once more—though in this case it would be oil instead of offensive nuclear weapons that are on board the incursionary vessel.
    This ship may veer off that current course and head elsewhere, or it could be meant to test the US oil blockade, intentionally poking at what seems to be an impenetrable barrier, to see if it’s all just talk. Even if just that one tanker makes it through, it’s carrying enough oil to provide about a week’s worth of energy to the Cuban people, which could serve as a sort of release valve on the pressure-cooker stress that has led to the aforementioned protests against the government.
    Most analysts expect this and future vessels will turn off when formally confronted, though, and this isn’t the first ship that’s attempted to break this new blockade of Cuba; and previous attempters have indeed pulled off before a shot was fired by the blockading fleet.
    Trump has in recent weeks said that he believes he’ll be able to take Cuba, and/or do whatever he wants to the island and its people, and that could just be talk, or it could be that, like in Venezuela, and to some degree Iran, many of the locals would welcome that kind of change, despite the violence and suffering that would no doubt come with it.
    In the meantime, though, millions of Cubans are going without reliable energy, food, medical care, and other modern necessities, which could push them to take the risk of revolutionary action, but it could also turn them against the outside enemy, reinforcing support for the tyrannical Cuban government against the harmful and oppressive actions of the American military, rather than nudging them into government overthrow.

    Petroleum-powered vehicles, cars and trucks and SUVs of the kind that have become the standard since the mid-20th century, work by mixing fuel that you put in the tank when you fill up at the gas station with air, in the engine, and then creating a controlled explosion—in modern vehicles using what’s called a four-stroke combustion cycle of intake, compression, combustion, then exhaust—in order to move pistons which, in turn generate mechanical power by transferring that movement to the vehicle’s wheels.
    An electric vehicle, in contrast, functions by using electricity from a battery pack to power an electric motor. So rather than needing fuel to combust, which then moves pistons which then moves the wheels, EVs are a straighter-shot with less conversion of energy necessary, electricity powering the motor which powers the wheels.
    That simpler setup comes with many advantages, and that difference in the conversion of energy is a big one. Because most of the energy injected into the EV’s system is converted into mechanical movement for the wheels, this type of vehicle only loses about 11% of the energy you put into it to that conversion of electricity to mechanical energy process—around 31-35% is initially lost while charging, converting electricity to motion, and so on, but about 22% is recaptured by the vehicle’s brakes during operation, leading to that 11% average loss.
    A gas-powered vehicle, in contrast, because of the inefficiencies inherent in converting fuel to combustion to movement, loses somewhere between 75-84% of the energy you put into it at the gas station, much of that loss in the form of heat that is emitted as a result of that conversion process; this is an inevitable consequence of the thermodynamics of burning fuel to create motion, and one that means operating a gas-powered vehicle is inherently lossier, in the sense that you can’t help but lose the majority of what you put into it as waste, compared to an electric vehicle, which is less lossy to begin with, but even more efficient when you include that in-operation energy recovery.
    That baseline reality of energy usage means that modern electric vehicles will typically be cheaper to fuel, to power, because it requires less energy input to get the same amount of travel. This cost-benefit comparison shifts even further in favor of EVs when gas prices are high, though, and though currently the cost of EVs tend to be higher than gas-powered vehicles in most countries, EVs also offer substantially lower lifetime maintenance costs—an average of 40% lower than gas-powered vehicles, due largely to the dramatically reduced number of moving parts in EVs, and the lack of regular, recurring engine-related maintenance tasks, like oil changes and replacing spark plugs.
    Not even considering the externalities-related savings of owning and operating an EV, then, like the environmental costs of fuel emissions, such vehicles can save owners tens of thousands of dollars in costs over the span of their ownership—though gas-powered vehicles are still more popular in most markets in part because they’re just more common on car lots, their infrastructure—gas stations versus charging stations—are also more common, and because there are numerous convenience issues, like it being quite a bit faster to pump a tank full of gas than to charge EVs, which is more efficient, but also a piece-of-mind sort of benefit.
    What I’d like to talk about today are some recent innovations in the EV and especially EV-scale battery space, and what it might mean for this market in the coming years.

    After a relatively boom-y period in which EV sales saw a significant uptick, that uptick the consequence of friendly policies and subsidies from successive federal administrations and the rapid-fire innovations arriving in each new generation of EV model being pumped out by US makers, especially Tesla, the US car industry has in recent years pulled back from electric vehicles substantially—the most recent evidence of this being Honda’s recent announcement that three EV models they were planning to manufacture in the US will no longer see production.
    This was mostly a money decision, the raw and partially manufactured components necessary for US-based car companies to produce EVs are now burdened with new, Trump-era tariffs, that make producing finished products of this kind in the US all but impossible; simply too expensive to make.
    This is also an acknowledgment, though, that Chinese EVs have just gotten so good and so inexpensive for what you get, that it’s simply not possible to compete, not within the current economic and regulatory climate, but also not in the immediate future, even lacking those tariffs, because of how much of a lead Chinese car companies have earned for themselves in this space.
    New impositions by the second Trump administration, including those tariffs, but also the killing of EV incentives, and a recent decision to cease enforcing emissions and fuel economy standards, basically telling the industry to make vehicles that pollute more, if they like, have absolutely influenced this state of affairs.
    But the quality of new Chinese EVs, the speed at which a large quantity of them can be produced, and the affordability of these vehicles is simply too much for even the world’s most otherwise competitive and industry-owning companies, the most renowned car brands, to match.
    There are a few serious EV players in other parts of Asia, and some US companies, like Lucid Motors, are still trying to carve out a space for themselves, pivoting toward skateboard-style platforms that will allow them to use fewer scarce products, like expensive wiring, by using essentially the same base for all of their models, allowing them to ramp-up efficiencies of scale faster, and Rivian, which is trying to claim the outdoorsy, Jeep-esque facet of the US EV market; and Tesla of course continues to own a lot of mindshare in this industry, despite seeming to be pivoting toward AI, autonomous vehicles, and political concerns in recent years.
    But this is increasingly China’s domain, and that dominance is the result of a multi-decade push to own basically all the infrastructure and technologies required to electrify their economy, from the ground-up.
    As a consequence of that dominance, and all the renewables and battery-making facilities and investments in the relevant companies made by the government for the past few decades, we’re now seeing impressive technological feats coming out of China, like the recently successfully test-flown Sky Dragon electric vertical takeoff and landing aircraft, which looks something like a drone combined with a helicopter, and which can reportedly carry either 10 passengers or a ton of cargo up to 155 miles, which is about 250 kilometers, on a single charge, taking off and landing from helipads, so no runway necessary.
    But the already on-the-market, everyday applications of this tech are arguably even more impressive, considering that car-markers in other countries cannot accomplish anywhere near the same, and maybe won’t be able to do so for years.
    Chinese carmaker BYD is the top entrant in this space right now, in China and globally, by many metrics, and in early March of 2026 they announced a new battery, called the Blade Battery 2.0, which allows the vehicles it powers to be driven more than 621 miles on a single charge.
    That’s compared to the around 400 mile range most large-tanked gas-powered cars can claim. Though even as batteries have gotten larger and more efficient, in terms of their energy storage and expenditure, charging them up has still taken quite a bit longer than filling a tank with gas, often requiring a wait of 30 minutes, though that’s usually just for a small top-up, and only if you have access to a fast-charger. A full-charge sometimes requires as much as 24 hours, if you’re using a small, non-fast public or a home charger.
    This differs quite a lot depending where in the world you are, the nature of your EV, and the capacity of the charger you’re using. In general, Tesla superchargers can take a Tesla’s battery from 20% to 89% in around 15-30 minutes, which on average provides another 200 miles of travel; topping it up to 100% usually takes about an hour.
    This new battery from BYD, though, which has that 621 mile capacity, can be charged from 10% to 80% in just 6 and a half minutes—and that’s not theory, that exact feat was shown in a public, onstage demonstration.
    This isn’t a claim about a technology that will soon arrive, in other words, this is a technology that’s already here, for BYD vehicles, at least. And at six and a half minutes for around 300 miles of range, that brings EVs into the same convenience range as gas vehicles, just a minute or so longer than the average stop at a gas station.
    This of course will require specialized charging stations, and those stations will take a while to roll out. The company has said they’ll have 15,000 of their so-called megawatt charging stations available across China by the end of 2026, building 4000 of them, themselves, and the rest through joint ventures. They’re also planning to have about 3000 of these chargers built across European by the end of the year.
    All of which will likely further reinforce and lock-in BYD’s advantages over its local and foreign competition, at least for the next several years.
    Now, it’s worth mentioning that China’s ’s EV industry is currently a bit tumultuous, the stock prices of companies like BYD tumbling due to wild competition on the Chinese market that until recently has been encouraged by the government, which favors a brutal sort of evolutionary business environment for its favored industries, most of the entrants eventually dying off and leaving fewer, but very strong and internationally competitive companies once the melee has died down.
    It’s generally assumed that companies like BYD will cope with this crisis of too-low prices and vehicle overproduction—they and their Chinese competitors are making a lot more EVs than their existing markets can bear—they’ll cope by becoming more aggressive with their international expansion, dropping gobs of these incredibly competitive vehicles in more markets, hoping to offload all that stock, but also to suffocate inferior but more expensive local offerings and, consequently, create more lock-in with international customers through those superior products.
    There’s a parallel push for autonomous EVs in many of these markets, which is several years behind the evolution of EV tech, but is also evolving rapidly within China, using that same ultra-brutal competition tactic. These companies are thus quite a bit further along than most of their global competitors, and it seems likely that the semi-autonomous tech built into these newly exported vehicles will help give Chinese companies a leg-up when it comes to exporting autonomous tech to the world, in the next few years.
    All of which demonstrates the Chinese market’s major head-start in this and connected technologies, and which points at a serious concern, not just for the US, but for pretty much everyone, as most of these technologies, like better batteries, are relevant not just for the consumer car industry, but also basically every other field, including future military technologies, and tech related to the AI and broader semiconductor industries, which could lead to still-more, and more varied advantages in the near-future.

    2026 Iran War

    10/03/2026 | 16 mins.
    This week we talk about Khamenei, Trump, and Netanyahu.
    We also discuss Venezuela, Cuba, and cartels.
    Recommended Book: Plagues upon the Earth by Kyle Harper
    Transcript
    Ali Hosseini Khamenei was an opposition politician in the lead-up to the Iranian Revolution that, in 1979, resulted in the overthrow of the Shah—the country’s generally Western government-approved royal leader—and installed the Islamic Republic, an extremely conservative Shia government that took the reins of Iran following the Shah’s toppling.
    Khamenei was Iran’s third president, post-Shah, and he was president during the Iran-Iraq War from 1981-1989, during which the Supreme Leader of Iran, the head of the country, Ruhollah Khomeini sought the overthrow of then Iraqi leader Saddam Hussein. Khomeini died the same year the war ended, 1989, and Khamenei was elected to the role of Supreme Leader by the country’s Assembly of Experts, which is responsible for determining such roles.
    The new Supreme Leader Khamenei was reportedly initially concerned that he wasn’t suitable for the role, as his predecessor was a Grand Ayatollah of the faith, while he was just a mid-rank cleric, but the constitution of Iran was amended so that higher religious office was no longer required in a Supreme Leader, and in short order Khamenei moved to expound upon Iran’s non-military nuclear program, to expand the use and reach of the Islamic Revolutionary Guard Corps, in-country and throughout the region, and he doubled-down on supporting regional proxies like Hezbollah in Lebanon, the Houthis in Yemen, and Hamas in Gaza, incorporating them into the so-called Axis of Resistance that stands against Western interests in the region—the specifics of which have varied over the decades, but which currently includes the aforementioned Hezbollah and Houthis, alongside smaller groups in neighboring countries, like Shiite militias in Bahrain, and forces that operate in other regional spheres of influence, like North Korea, Venezuela, and at times, portions of the Syrian government.
    Khamenei also reinforced the Iranian government’s power over pretty much every aspect of state function, disempowering political opponents, cracking down on anyone who doesn’t toe a very conservative extremist line—women showing their hair in public, for instance, have been black-bagged and sometimes killed while in custody—and thoroughly entangled the functions of state with the Iranian military, consolidating essentially all power under his office, Supreme Leader, while violently cracking down on anyone who opposed his doing whatever he pleased, as was the case with a wave of late-2025, early 2026 protests across the country, during which Iranian government forces massacred civilians, killing somewhere between 3,000 and 35,000 people, depending on whose numbers you believe.
    What I’d like to talk about today is a new war with Iran, kicked off by attacks on the country from Israel and the United States that led with the killing of Khamenei and a bunch of his higher-up officers, how this conflict is spreading across the region and concerns about that spreading, and what might happen next.

    On February 28, 2026, the US and Israel launched a wave of joint air attacks against Iran, hitting mostly military and government sites across the country. One of the targets was Khamenei’s compound, and his presence there, above-ground, which was unusual for him, as he spent most of his time deep underground in difficult-to-hit bunkers, alongside a bunch of government and military higher-ups, may have been the rationale for launching all of these attacks on that day, as the attackers were able to kill him and five other top-level Iranian leaders, who he was meeting with, at the same time.
    This wave of attacks followed the largest military buildup of US forces in the Middle East since the invasion of Iraq back in 2003, and while military and government targets were prioritized, that initial wave also demolished a lot of civilian structures, including schools, hospitals, and the Grand Bazaar in Tehran, leading to a whole lot of civilian casualties and fatalities, as well.
    In response, Iran launched hundreds of ballistic missiles and drones at Israel, and at US bases throughout the region—these bases located in otherwise uninvolved countries, including Qatar, Bahrain, the UAE, Kuwait, Iraq, Jordan, and Saudi Arabia. Iranian missiles and drones also hit non-military targets, and in some cases maybe accidentally hit civilian infrastructure, in Azerbaijan, and Oman, alongside a British military base on the island of Cyprus.
    The Iranian president apologized in early March for his country’s lashing out at pretty much everyone, saying that there were miscommunications within the Iranian military, and that Iran wouldn’t hit anyone else, including countries with US bases, so long as US attacks didn’t originate from those bases.
    Despite that apology, though, Iranian missiles and drones continued to land in many of those neighboring countries following his remarks, raising questions about communications and control within the now-decapitated Iranian military.
    This new conflict follows long-simmering tensions between Iran and Israel—the former of which has said it will someday wipe the latter from the face of the Earth, considering its existence an abomination—and long-simmering tensions related to Iran’s nuclear program, which the government has continuously said is just for civilian, energy purposes, but which pretty much everyone suspects, with a fair bit of evidence, is, in parallel, also a weapons program.
    Iran’s influence throughout the region has been truncated in recent years, due to a sequence of successes by the Israeli military and intelligence services, which allowed them to hobble or nearly wipe out traditional Iranian proxy forces like Hamas, Hezbollah, and the Houthis, which have collectively surrounded and menaced Israel for decades.
    Those menacing forces more or less handled, Israel has become more aggressive in its confrontations with Iran, exchanging large air attacks several times over the past handful of years, and the US under Trump’s second term continues to see Iran as the main opposition to their efforts to build a US-aligned counterbalance against Russian and Chinese influence in the Middle East, with Israel, Saudi Arabia, and increasingly entities like Qatar and the UAE playing ball with the West, while Iran and its allies stand firm against the West.
    Trump has regularly threatened to act in Iran, usually waiting for the Iranian government to do something really bad, like that recent massacre of civilians following those large anti-government protests in late-2025, early 2026, and that to some degree has served as justification for the massing of US military assets in the region, leading up to this attack.
    Now that the attack has launched, a new war triggered, the question is how big it will get and how long it will last.
    For the moment, it looks like Iran’s government and military is very much on the back foot, a lot of their assets taken out in that initial wave, and they’re still scrambling to put someone in charge to replace Khamenei and those other higher-ups who were assassinated at the outset of this war—that’ll likely change soon, maybe even before this episode goes live. But whomever takes the reins will have quite the task ahead of them, probably—according to many analysts, at least—aiming to just hold out until the US runs out of ammunition, which is expected to happen within a week or so, at which point Iran can launch surgical attacks, aiming to make this war too expensive, in terms of money and US lives, for the Trump administration to continue investing in, as money and lives are especially expensive in an election year, which 2026 is. So the idea is to grind the US down until it makes more political sense for Trump to just declare victory and leave, rather than allowing this to become a Vietnam or Afghanistan situation for his administration.
    It’s also generally expected that when the US pulls out, Israel probably will too, as they’ve already made their point, tallied a bunch of victories, and set Iran back in a lot of ways; they could walk away whenever they like and say they won. And Iran would probably be incentivized to, at that point, avoid doing anything that would lead to more punishment, though they would almost certainly immediately begin rebuilding the same exact centralized, militarized infrastructure that was damaged, the only difference being they would have someone else on top, as the Supreme Leader. Relations could be even worse moving forward, but it would probably be at least a few years before Iran could do anything too significant to their regional enemies, which I guess if you’re Israel does, in fact, represent a win.
    But considering the unlikelihood of permanent change in Iran, the big question here, in the minds of many, is what this war, this attack, is even for.
    For Israel, the main purpose of any attack against Iran is to weaken or destroy an enemy that has made no secret about wanting to weaken and destroy them. For the US, though, and the Trump administration more specifically, the point of all this isn’t as clear.
    Some contend that this is another effort to steal attention and headlines from the increasingly horrifying revelations coming out of the investigation into the Epstein files, which seem to indicate Trump himself was involved in all sorts of horrible, pedophilic sexual assault activities with the late human-trafficker.
    Some suspect that the apparent victory in grabbing former Venezuelan president Maduro from his own country and whisking him away to the US without suffering any US casualties has emboldened Trump, and that he’s going to use the time he’s got to take out anyone he doesn’t like, and may even specifically target authoritarian leaders who will not be missed—who oppress and kill their own people—because then it’s difficult for his political opponents to call him out on these efforts.
    Most Venezuelans are happy to see Maduro gone, and many Iranians celebrated when Khamenei was assassinated. Trump has publicly stated that he intends to go after Cuba, next, and continues to suggest he wants a war of sorts with Mexican and south and central American cartels, which follows this same pattern of demonstrating a muscular, aggressive, militarized United States doing whatever it wants, even to the point of kidnapping or assassinating foreign leaders, but doing so in a way that is difficult to argue against, because the leaders and other forces being taken out are so horrible, at times to the point of being monstrous, that these acts, as illegal as they are according to internal laws, can still seem very justified, through some lenses.
    Still others have said they believe this is purely an Israeli op, and the US under Trump is just helping out one of Trump’s buddies, Israel’s Netanyahu, who wants to keep his country embroiled in war in order to avoid being charged for corruption.
    The real rationale could be a combination of these and other considerations, but the threat here, regionally, is real, especially if Iran continues to lash out at its neighbors.
    This part of the world is renowned for its fuel reserves and exports, and every time there’s a Middle Eastern conflict, energy prices rise, globally, and other nations that produce such exports, like Russia, benefit financially because they can charge more for their oil and gas for a while—gas prices in the US have already increased by 14% over the past week as a result of the conflict—and those increases also then the raises the price of all sorts of other goods, spiking inflation.
    Another huge concern here, though, is that this part of the world is highly reliant on the desalination of water just to survive; massive desalination plants, most located along the coast, where they are very exposed to military threats, are at risk if Iran and Saudi Arabia, or Kuwait, or Oman start firing at each other in earnest.
    About 90% of Kuwait’s drinking water comes from these sorts of plants, and about 86% of Oman’s and 70% of Saudi Arabia’s do, as well.
    Earlier in this war, a US strike damaged an Iranian desalination plant, and the Iranian foreign minister made a not-so-veiled threat against such plants in neighboring countries, saying the US set the precedent of attacking such infrastructure, not them.
    Worth noting here, too, is that many desalination plants are attached to power stations, located within the same facility, so attacks on power infrastructure, which are already common in any conflict, could also lead to more damaged desalination plants, all of which could in turn create massive humanitarian crises, as people living in some of the hottest, driest parts of the world find themselves, in the millions, without drinkable water.
    The potential for a spiraling humanitarian disaster increases with each passing day, then, which would seem to increase the likelihood that someone will stop, declare victory, and move on to the next conflict. But there’s always the chance the one or more of the involved forces will clamp down and decide that it’s in their best interest to keep things going as long as possible, instead—and in this case, it would likely be Iran playing that role, locking the US and Israel and their allies into a grinding, long-term conflict that no one would actually win.
