  • Cuban Oil Blockade

    Cuban Oil Blockade
    Mar 24 2026
    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 IslingtonTranscriptCuba 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 ...

  • Better Batteries

    Better Batteries
    Mar 17 2026
    This week we talk about BYD, Tesla, and the Blade Battery 2.0.We also discuss EVs, internal-combustion engines, and autonomous vehicles.Recommended Book: Blank Space by W. David MarxTranscriptPetroleum-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 ...

  • 2026 Iran War

    2026 Iran War
    Mar 10 2026
    This week we talk about Khamenei, Trump, and Netanyahu.We also discuss Venezuela, Cuba, and cartels.Recommended Book: Plagues upon the Earth by Kyle HarperTranscriptAli 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 ...
