How a panther habitat became a battleground for the state’s environmental groups

About 27 miles inland from Florida’s southwestern coast sit three empty swaths of land among a sea of green. This undeveloped area represents both the future of Florida’s development and the culmination of a 20 year fight between the state’s environmentalists.
“What happens here will change the face of Collier County forever,” April Olson, a researcher at the Conservancy of Southwest Florida, told me.
Home to affluent Naples and its fast-growing population of retirees, the county recently approved plans for four new villages to be built in one of Florida’s last undeveloped areas, which is sandwiched between some of the state’s biggest and most important nature reserves. The region hasn’t enjoyed official protection, per se, but it has enjoyed a special status. But with almost half a million people having moved to Florida just last year, and more on the way, the county of 300,000 inhabitants and counting has decided to keep building.
Yet if this sounds like a typical story of developers versus environmentalists, it isn’t. Instead, it has become a unique point of tension among environmental groups in Florida. While one group believes it’s their responsibility to be a part of this conversation and help manage unavoidable development, the other side believes it’s their role to fight against it.
“I’m very surprised environmentalists are taking this pragmatic approach,” said Matthew Schwartz, executive director of the South Florida Wildlands Association. “This isn’t what environmentalists do.”
The result is a rift among the guardians of Florida’s wildlife.
The environmentalists all agree on what they’re trying to protect: the panthers. From a conservation perspective, the region has acted as a corridor for the state’s remaining endangered panthers, of which there are only 120-230 adults left in the wild, to travel.
The area is surrounded by protected nature reserves. To the north is a complex of wildlife, bird sanctuaries, and wetlands; to the northeast are two different wildlife management areas, and to the south is the Florida panther national wildlife refuge, another wildlife management area that is home to bears, a state forest, a state preserve, and a national preserve that ultimately extends into the Everglades.
“This area is a mosaic of habitat types that allows the panther to live,” said Schwartz. “What they are doing essentially fragmented those complexes from one another.”
But to understand how the area has become a battleground of environmentalist groups, you’ll first have to dive into the area’s weird regulatory history.

The villages being constructed amid this remarkably untouched land are the most recent outcome of a partnership between developers, land owners, and environmental groups. Called the Rural Lands Stewardship Area (RLSA) program, this partnership changed zoning over 20 years ago to allow for more dense development in exchange for environmental protections.
“At the end of the day, the RLSA is a compromise,” said Meredith Budd, who worked on this project when she was a policy director at the Florida Wildlife Federation. (She is now the director of external affairs for the Live Wildly Foundation.)
The RLSA was born way back in 1999, when then-Florida Governor Jeb Bush put a moratorium on development in Collier County. He claimed that urban sprawl in Naples, the state’s fastest growing city at the time, had gotten out of hand and that everyone needed to figure out a better solution for development that preserved agricultural lands and protected the environment.
When the RLSA was first discussed and proposed in 2002, most environmentalist groups, including the Conservancy of Southwest Florida, were on board. The battle that has emerged among these groups has its roots in some imprecise wording from the original proposal that almost tripled the amount of land that developers could build on.
The total area was — and still is — about 198,000 acres. Just over half of the acreage is protected nature reserves, with the rest mostly agricultural land available for development. But there’s a catch. Prior to the RLSA, the zoning only allowed for a single house, called a “ranchette,” to be built every five acres on the developable land. While some of these solitary homes exist today on farms, the majority of the area is still uninhabited, therefore serving as a wildlife corridor as well as porous land to absorb heavy rainfall or storm surges.
That’s where the RLSA was supposed to come in. Published in 2002, it proposed to change the allotment, swapping denser housing for more protected land. It indicated that 16,805 acres of the 98,000 available could be built on if developers earned allowances by restoring other land, although what would count as restoration was a little hazy. The language around these numbers was also very vague, critically leaving room to increase the amount of credits able to be earned and, subsequently, the acres developed. It ultimately increased the amount of land up for development to 45,000 acres. Many of the conservancies didn’t realize this change until the five-year review in 2007.
“We were supportive of RLSA,” said Olson. “But we believe the goals are not being met. The public was promised that 16,000 acres would be developed and that 91% of the area would be preserved.”
But those working with the RLSA think what’s done is done. “There’s no point in going back and figuring out what happened,” said Budd. “The allowable footprint is over 40,000 acres. We have to move forward and figure out whether wildlife connections can be made.”
The intent of the 1999 moratorium was to curb development for the benefit of conservation. The RLSA is still attempting to do that, but it’s a voluntary program, and much of the power lies with the landowners.
But in the past few years, Florida’s real estate market has boomed and land use planning regulations have been weakened. This combination made landowners restless to start building, more able to do so, and more impatient when it comes to making concessions to conservationists. Pro-RLSA environmentalists say playing hardball in negotiations with developers just won’t fly anymore.
“These organizations trying to save habitat by killing these programs aren’t helping, they’re making it worse,” said Elizabeth Fleming, a representative at Defenders of Wildlife, which supports the RLSA.
The four new villages, which are cumulatively known as “The Town of Big Cypress,” are only the most recent developments in the RLSA. The first, called Ave Maria, began building in 2005 but construction paused for a while after the recession. Big Cypress is one of the first cohesive plans out of the RLSA to keep building since then, but six more are in development. Though not nearly finished yet, the website for the Town of Big Cypress promises to fulfill all the expectations of the American dream. “Families strolling along storefronts with ice cream cones in hand … on-street parking for easy access to the hair salon, dog groomer, dry cleaner, and local grocer,” the website says. It promises happiness, community, convenience — even good weather and “responsible growth.”.
Today, both sides agree that no development would be the best way forward. “In a perfect world, I would love to see no more of it developed,” said Budd. “If I was Queen, I would say you no longer have property rights.”
Bradley Cornell, policy associate at the Audubon Society of the Western Everglades, helped make the RLSA a reality. “I’d much rather build a wall at the Georgia line and tell everyone to go home,” he said. “But we’re expected to get another 15 million people in Florida over the next 50 years. All of these people are moving to Florida. Where in the hell are we going to put them without ruining Florida’s nature?”
Between July 2021 and 2022, 444,500 people moved to Florida, according to the Tampa Bay Economic Council. Despite the increase in hurricanes and flooding and the decrease in affordable insurance, Florida is more popular than it has ever been.
Those in favor of the RLSA say that development is going to happen with or without them, and the RLSA allows them a platform to negotiate. “This is the best compromise we could have gotten,” Cornell said.
The primary benefit of the RLSA is that it offers a chance at higher density living with a potentially smaller ecological footprint. The pro-RLSA group, for example, has kept some developments from further encroaching on panther habitat. These conservationists have negotiated underpasses and fencing in three different areas to allow panthers and wildlife to cross roads without getting hit. They have also gotten the county to require bear proof trash cans, lowering lights to avoid light pollution, and smoke easements, which require new tenants to sign off on necessary controlled burns to maintain the environment for the panther preserve. From the Town of Big Cypress alone, the RLSA crediting system requires the developers to permanently preserve 12,000 acres. In this case, they will be restoring the hydrology of a major wetland nearby, according to Cornell.
“We’re just trying to have a seat at the table and ensure that we can get the best conservation outcomes knowing that the landowners have the rights to this land and are permitted to do whatever they want,” said Fleming.
The pro-RLSAers also pushed for more protections than they got. For 10 years, they fought for a Habitat Conservation Plan (HCP) that would have legally bound the landowners to certain conservation requirements, according to Budd. But pushback from the anti-RLSA groups slowed the process so much that eventually it wasn’t worth the landowners’ time and it was withdrawn in August 2022. Those against the RLSA had many qualms with the HCP and don’t see its withdrawal as a loss.
The other arguments against the RLSA are plentiful.
The anti-RLSA group contends that any development will harm the panthers. “This project would be the nail in the coffin of the panthers,” said Olson.
This side of the debate also thinks that the zoning rules that predated the RLSA, which previously allowed for ranchettes every five acres, were highly unlikely to practically result in development. They argue that implementing the road infrastructure required for such scattered housing would be prohibitively expensive, suggesting that if the RLSA hadn’t been proposed, this area would have been left untouched.
“It’s highly unlikely that they would come in and build five-acre ranchettes,” said Olson. “They would need thousands of miles of new roads. One new 100 mile road was calculated to cost $111 million in 2015.”
Schwartz agreed. “This is completely unpopulated, undeveloped rural land,” he said. “People don’t want to buy a swath of rural land and move into undeveloped lands.”
But pro-RLSA environmentalists think that perspective is naive. “That’s a false argument,” says Fleming. “It’s based in no reality. People are moving here and that area is the least expensive if you want to be near Naples. I see no reason why that wouldn’t continue.”
Budd added that money is not a concern in this area. “Collier County is one of the highest wealth points in the state, if not the whole country,” she said. “So to say this would be too expensive is unreasonable.”
Another area in between Naples and the RLSA, called Golden Gate Boulevard, had the same one-in-five zoning restrictions as the RLSA and has been heavily developed in the last 10 years.
The RLSA plan also does not seem to be taking the changing climate into account. According to Olson, 96% of Collier County is susceptible to storm surge. The inland parts aren’t as vulnerable, but there is still a high threat and the area’s porosity would be lost with these developments. In addition, the RLSA will experience 109 days where the heat index is above 100 degrees Fahrenheit in 2023, and 138 in 2053, according to The Washington Post’s interactive map on heat waves.
County Commissioner Bill McDaniel said that climate change was not a concern in the process of developing The Town of Big Cypress. “There are no stipulations with regard to climate change because it’s such a nebulous discussion point,” he said.
Though the commissioner agreed that many climate-friendly technologies are comparable, if not less expensive to purchase and maintain, the RLSA does not require developers to install permeable concrete, heat pumps, special shade trees for temperature, or solar panels on the houses.
“We recommended numerous policies that would encourage more energy efficient homes and appliances, improve permeability of sidewalks, require complete street designs that all users can use, ease traffic congestion, increase Florida friendly plants that require less water, include stipulations for storm water runoff, etc.” said Olson. “They just ignored it. I have not once heard the County even discuss heat issues or climate issues.”
Budd said that the choice to build inland in itself is a climate-conscious decision. “When looking at this long term and the threats of climate change, the main threat is that people will be moving inland,” she said. “Where we put the development is the most important thing.”
One of the biggest landowners in the area, named for the county’s namesake, Collier Enterprises, echoed Budd’s sentiment in emailed responses. “The Town of Big Cypress is 19 miles from the coast, similar to Babcock Ranch, which did not sustain damage from the recent Hurricane Ian, having one of the largest reported storm surges ever recorded.” He added that most of the national buildings in the area provide options for energy efficiency and smart home technology
Though both sides have very different ideas of how to be involved in development, they are both aware that development is coming to Eastern Collier County and share the same ultimate desires for the region.
“We do know that the RLSA is going to grow,” said Olson. “We know that Collier County is going to grow. We just think it could be done more sustainably.”
Environmentalists everywhere are grappling with how to best save the last bastion of the lands and animals that sustain us. Depending on which side you take in the RLSA fight, it has become a question of cynicism versus hope or pragmatism versus pipe dreams.
Those against the RLSA are still championing its original goal: to preserve the environment and to curb excessive development. “The goal of the program wasn’t to allow each and every landowner to maximize their profit to the greatest extent,” said Nicole Johnson, Director of Governmental Relations at the Conservancy of Southwest Florida.
The other side has committed to pragmatism. “At the end of the day, the dollar speaks,” said Budd. “And unfortunately it speaks louder than the voices against the project.”
As regulations recede in Florida, the RLSA disagreement signals a philosophical choice environmentalists will increasingly have to make: If we can’t beat them, should we join them?

Current conditions: A wave of summer heat is headed for the East Coast, with midweek temperatures surpassing 90 degrees Fahrenheit in Washington, D.C. • Guam and the Northern Mariana Islands are bracing for winds of up to 190 miles per hour as Super Typhoon Sinlaku bears down on the U.S. territories • At least 30 people have died in floods in Yemen, which just recorded its highest rainfall in five years.
The Trump administration is holding up some funding for grants at the National Oceanic and Atmospheric Administration, The Hill reported. On April 1, the University of Colorado put out a statement saying that a federal pause on funding had put scientists who collect data about the atmosphere “at risk for elimination” after the White House Office of Management and Budget had “not released these funds.” The university’s Cooperative Institute for Research in Environmental Sciences said that roughly 30 days before running out of funds to pay scientists, “we were informed that NOAA has put a pause on all grant actions.”
As I told you back in December, the Trump administration is also working to dismantle the National Center for Atmospheric Research in Colorado, an institution credited with many of the biggest scientific breakthroughs in our understanding of weather and climate over the past 66 years since its founding. In a post on X at the time, Russell Vought, the director of the White House’s Office of Management and Budget, called the institute “one of the largest sources of climate alarmism in the country,” and said the administration would be “breaking up” its operations.
Secretary of Energy Chris Wright is scheduled to testify Wednesday morning before the House Committee on Appropriations to defend the White House’s latest budget request for his agency. He’s not the only chieftain of a federal agency with relevance to Heatmap readers who’s coming before Congress this week.
U.S. Customs and Border Protection plans to launch the first phase of what’s called the Consolidated Administration and Processing of Entries tool in the agency’s automated commercial secure data portal to allow companies to request refunds of Trump administration tariffs the U.S. Supreme Court ruled unlawful earlier this year. Solar companies are among the thousands of American businesses that filed complaints with the U.S. Court of International Trade for refunds prior to the Supreme Court’s ruling. Those, according to Solar Power World, include American Wire Group, Canadian Solar, GameChange Solar, Fluke, Hellerman Tyton, Kinematics, JA Solar, Jinko Solar, Longi, Merlin Solar, Qcells, and Trina Solar.

Established in early 2021, California Community Power is a quasi-governmental organization formed out of nine power providers across the Golden State. On Monday, the agency inked a series of deals with geothermal power developers to expand what’s widely considered one of the most promising clean-energy sources for California, which has some of the continent’s best hot-rock resources. XGS Energy, the Houston-based startup promising to build next-generation closed-loop geothermal systems, announced a deal to build 115 megawatts of power in the state. Zanskar, the geothermal company using AI to locate untapped conventional geothermal resources, also signed an agreement with the agency.
Zanskar in particular ranked among the most promising climate-tech startups on the U.S. market in Heatmap’s poll of experts earlier this year. The company last year announced its biggest find yet, Heatmap’s Katie Brigham reported last year. XGS, meanwhile, is drawing support from the nuclear industry, as I previously reported for Heatmap.
The developer behind a major Massachusetts offshore wind farm is suing its turbine manufacturer in a bid to keep the company from backing out of the project. By February, the Vineyard Wind project off Cape Cod had installed 60 of the project’s 62 turbines, as I reported at the time. Yet the parent company behind GE Renewables, the maker of the project’s turbines, said “it would be terminating its contracts for turbine services and maintenance at the end of April,” the Associated Press reported. GE Vernova, the parent company, says Vineyard Wind owes it $300 million already.
The war in Iran is taking a toll on Central African minerals. Miners in the Democratic Republic of the Congo are curbing output of copper and cobalt as the war cuts supplies of sulfuric acid needed for leaching minerals out of rock, Reuters reported. Mine managers are reducing cobalt production to conserve chemicals.
The deal represents one of the largest public-private partnerships in the history of the national labs.
I’ll admit, I thought I might be done covering fresh fusion startups for a while. In the U.S., at least, the number of new industry entrants has slowed, and most venture capital now flows towards more established players such as Commonwealth Fusion Systems and Helion. But in February, a startup called Inertia Enterprises made headlines with its $450 million Series A raise. It’s aiming to commercialize fusion using the physics pioneered at Lawrence Livermore National Laboratory, the only place yet to achieve scientific breakeven — the point at which a fusion reaction produces more energy than it took to initiate it.
That achievement first came in 2022 at the lab’s National Ignition Facility in Berkeley, California. On Tuesday, Inertia announced that it’s deepening its partnership with Lawrence Livermore, creating one of the largest private sector-led partnerships in the history of the national lab system. This collaboration involves three separate agreements that allow Inertia to work directly with the lab’s employees on research and development, while also giving the startup access to nearly 200 Lawrence Livermore patents covering fusion technology.
The startup’s team isn’t merely a group of enthusiasts galvanized by the national lab’s fusion milestone. Alongside Twilio’s former CEO Jeff Lawson and fusion power plant designer Mike Dunne, Inertia’s other co-founders is Annie Kritcher, a senior employee at Lawrence Livermore who has led the physics design for NIF’s fusion energy experiments since 2019.
“We’re not starting from zero,” Kritcher told me, putting it mildly. “And that was really, really important to me when I decided to co-found this company.” Or as Lawson told me after the company’s fundraise in February, “the government put 60 years and $30 billion into NIF trying to get that thing to work.”
The technical approach pursued by Lawrence Livermore — and now by Inertia — is called inertial confinement fusion. In this system, high-powered lasers are directed at a millimeter-scale pellet of fusion fuel, typically a mixture of the hydrogen isotopes deuterium and tritium. The laser energy rapidly compresses and heats the pellet to extreme temperatures and pressures, driving the nuclei to fuse and releasing enormous amounts of energy. But NIF didn’t build its system for commercial purposes. Rather, its primary mission is to support the domestic nuclear weapons stockpile by recreating the extreme conditions inside a nuclear detonation, allowing scientists to study how U.S. weapons perform without conducting explosive tests.
To translate the lab’s research into a commercially viable device, Kritcher explained, Inertia must significantly increase the lasers’ efficiency and power output, targeting a system roughly 50 times more powerful than existing lasers of its class. The startup is also working to scale production of its fusion targets to drive down costs and enable mass manufacturing.
Inertia is not the only company attempting to commercialize this general approach, however. Back in 2021, as Lawrence Livermore moved closer to its breakeven moment, the future founders of the startup Xcimer Energy were taking note. Convinced that the fundamental physics of inertial confinement had been proven, they thought, “if we’re going to do this, we have to do it now,” Xcimer's CTO, Alexander Valys, told me a few years ago. He and his co-founder quit their day jobs, and Xcimer went on to raise a $100 million Series A round in 2024. Others joined in on the hype, too — the Fusion Industry Association reports 13 fusion companies that were founded or emerged from stealth between summer 2022 and summer 2023, a record for the sector.
Kritcher told me that none are adhering as closely to NIF’s successful design as Inertia. “There are fundamental technical differences between us and the other laser approaches,” she told me, explaining that while Xcimer and others are using broadly similar methodologies to produce a hot, dense plasma, the underlying physics behind their plan diverges significantly. Xcimer, for instance, is developing a novel laser architecture that hasn’t yet been demonstrated at scale, along with a different fuel capsule design than the one validated by NIF.
Kritcher will be allowed to continue her work at the lab thanks to what the company describes as a “first-of-its-kind agreement” enabled by the 2022 CHIPS and Science Act, which allows scientists at the national labs to participate in commercialization efforts with the goal of accelerating the transfer of knowledge to the private sector.
For the fusion engineer, it’s the ultimate dream come true. She first arrived at Lawrence Livermore as a summer intern in 2004, just before her senior year at the University of Michigan, and “fell in love with the lab and the NIF project,” which was still under construction at the time. She opted to attend the University of California, Berkeley for her masters and PhD in nuclear engineering so that she could continue her work there.
“I was starstruck by the possibility of fusion energy and [it having] such a big impact on humanity, and that really kept me going for a long time,” she told me. But after the NIF facility was finally completed in 2009, it failed to achieve ignition by its initial 2012 target.
By then, Kritcher was a postdoctoral fellow, and attention at NIF began to shift toward supporting the nation’s nuclear stockpile. Fusion energy was “always in the back of my mind, driving me day to day,” she said, “but you sort of forget about it, and you lose a little bit of that excitement and spark.” Under her guidance, NIF ultimately reached that watershed moment, which has since been replicated numerous times. And when it did, "it just reopened all those old inspirational feelings and motivations and excitement and it was like a 180 turning point where we all just go, oh, fusion energy is possible again with this approach.”
Many of the lab’s employees feel similarly, she said, and this close collaboration will allow some of the nation’s foremost experts in inertial confinement to work with the startup across a range of technical capabilities, including “the laser side, the target fabrication side, the simulations team side, the code development side, our physics design side,” Kritcher enumerated.
Inertia is looking to bring its first pilot plant online in the “2030s to 2040s,” she told me. By contrast, Commonwealth Fusion Systems — the most well-capitalized company in the sector — plans to connect its first plant to the grid early next decade, while Xcimer is targeting 2035. Kritcher is unfazed, though. While she acknowledges that other companies might complete their facilities sooner, she argues that Inertia still has an upper hand given that NIF effectively serves as the startup’s demonstration plant, something no other company has built.
Not to mention that all of the sector’s projected timelines remain highly speculative. There are serious technical and economic challenges that would-be fusion energy companies will have to overcome — Inertia not excepted — and the industry’s status 10 years down the line remains anyone’s guess. What’s crystal clear, however, is that a serious new contender has entered the race.
Big questions about naval strategy and the oil economy with Cornell University’s Nicolas Mulder.
After negotiations between the United States and Iran broke down Sunday without a deal, the United States Central Command said it would “begin implementing a blockade of all maritime traffic entering and exiting Iranian ports” Monday morning.
It’s hardly like traffic through the Strait of Hormuz had been unencumbered before that. The strait has been largely closed to through traffic since the beginning of March thanks to the threat of Iranian strikes on ships going in and out of the Persian Gulf. That has remained the case even after the ceasefire deal was supposed to have opened up the waterway last week. Only a few countries have been able to get their tankers out, mostly those with close trade relationships with Iran, including China.
President Trump has been seeking to reverse that state of play and open the strait to non-Iranian traffic (e.g. oil, liquified natural gas, and fertilizer coming in and out of the Gulf states), whether by badgering European allies to help clear the strait and by having U.S. Navy ships traverse the channel to clear mines and demonstrate it’s safe to navigate. He appears to have ultimately settled on blockading the blockaders.
The president said Monday on Truth Social that 34 ships had sailed through the strait on Sunday, a number that has not been confirmed by third party sources. In the run-up to the U.S. blockade, about 10 to 12 ships were sailing through the strait per day, according to marine data service Kpler and The New York Times.
So, is the blockade an escalation of U.S. pressure on Iran? A violation of the ceasefire? A “pacific blockade” designed to pressure Iran without resorting to direct strikes? And how would it work, anyway?
I spoke with Nicolas Mulder, an assistant professor of history at Cornell University and the author of The Economic Weapon: The Rise of Sanctions as a Tool of Modern War, to try and get some of my questions answered. This interview has been condensed and edited for clarity.
Let’s start from the beginning. What is a naval blockade? And how does it different from typical naval warfare?
A naval blockade is actually interesting because it is a form of warfare that has been quite regulated for quite a long time already under international law. A lot of our modern understanding of the laws of belligerence and neutrality actually comes from blockades because they impose an important stricture on international maritime traffic. As a result, they raise all sorts of questions about who wars are fought between, and what wars mean for the civilian economies of the countries involved, and what they mean for the relationship of the belligerent states and third countries.
For most of U.S. history, the U.S. was not the blockader, but the neutral wanting to bypass blockades. The reason that the United States concretely intervened in the First World War and began to really involve itself with the power politics of Eurasia in 1917 is because it insisted on its neutral rights to trade with Britain when Germany had declared an unrestricted submarine warfare campaign that was effectively a blockade of the British Isles.
Even before that, the Union used it against the Confederacy.
In the 18th century, all the big great power wars — the Seven Years War, the various succession wars, the Napoleonic Wars — all of those involved blockades.
What I find interesting is that we have this ceasefire. We have these negotiations, which are apparently still going on. But then we also have the blockade. You seem to be arguing that blockades are a part of warfare. So, is this implying that the U.S. Navy is still potentially going to be shooting at stuff, even if there’s a so-called ceasefire?
That’s the big uncertain aspect of the current situation. We are not back into the same war that we were in last week before the ceasefire took effect. The way I would interpret this is that it’s a kind of fudge. From the perception of the Trump administration, it needs to do something to not look weak, but at the same time wants to avoid the risks of a full resumption of kinetic warfare and a massive air campaign, which they had pursued for six weeks to very mixed and disappointing effects.
The one historical parallel that I think can help us make sense of what they may be attempting to do now is the practice in the 19th century of “pacific blockade.” There were several conflicts, beginning in the 1820s with the Greek War of Independence and then through a whole bunch of Latin American wars and Asian conflicts, where European great powers would blockade small countries — not to declare war on them, but to prevent any of their ships from entering or leaving to put serious pressure on them.
What they were doing in that situation was to use wartime levels of pressure without initiating the full war because they knew that the target states were basically too weak to retaliate and did not have the naval power to contest that blockade.
How can we see this operation in Iran as part of a continuum of using these strangulation-type strategies against much weaker opponents?
One way to interpret what they’re trying to do now is to apply that Venezuela-Cuba template to Iran, and to wager that if they play this carefully, they might be able to bring real economic pressure to bear without provoking Iran into as full-scale a retaliation as it was undertaking before.
But that Venezuela-Cuba template is difficult to implement in the case of Iran for two simple reasons. One is just that Iran has, of course, shown that it has quite a lot of military capacity to retaliate with drones and missiles, and also mines and small ships and submarines. It also has the ability to widen its own maritime disruption in the region, for example by working with the Houthis to really stem the flow of traffic through the Bab-el-Mandeb Strait.
What works in the Western Hemisphere, where the United States has a really unrivaled military dominance, may not be reproducible in this strategic theater.
What does the geography tell you about the ability to impose or contest a blockade like this?
They may be doing it with multiple rings, or multiple screens — a light initial screen, and then bigger barriers of ships a bit further away, so as to not risk most of their force too close to the Iranian coastline. We saw in the early phase of the war that some carrier strike groups began to operate over time further and further away from the Iranian coast, presumably to avoid the risk of being hit with missiles and drones.
In this case, one of the questions is, what kind of resources are needed to keep that going? The U.S. did run a blockade against Iraq for most of the 1990s that was in the Persian Gulf itself, which is very narrow. Iraq’s ports are a tiny sliver of land that ends in the Persian Gulf. So that was a very small stretch of coastline.
Iran should still be manageable, but it will require a wider screen, and potentially one that really crosses the entire Arabian Sea somewhere from the southern coast of Oman, diagonally, northeastwards to Pakistan, or at least the Pakistan-Iranian border, and potentially a bit further out. And if there is also interference in the Red Sea, then the U.S. Navy is going to have to route most of disabled forces all the way around Cape of Good Hope to move that whole force into the Indian Ocean.
I think that the Red Sea contingency is quite important to how this shapes up.
CENTCOM said yesterday that this blockade is on ships going in and out of Iranian ports. I wonder if this is unique historically — both a blockade of Iran and trying to impose freedom of navigation elsewhere?
It’s interesting, right? Because indeed, there is the commitment to freedom of navigation. But then it also has been suggested that the U.S. Navy will stop all ships that have paid any toll or transit fee to the [Islamic Revolutionary Guard Corps], and that paying that toll ipso facto would make their passage illegal. For that I don’t know any good historical precedent.
The other historical precedent is probably actually the Ottoman Empire and Russia and World War I. The Ottoman Empire was bottling up Russia’s Black Sea Fleet in the Black Sea by its control over the Turkish straits, which actually imposed a really serious, long run cost on the Russian economy. It’s one of the things that really fed us in the Russian Revolution. But at the same time, the Ottoman Empire was itself being blockaded by British and French forces in the Mediterranean.
Iran is blockading [Gulf Cooperation Council] states selectively — though of course, it is allowing through some shipments. But those shipments are then going to be intercepted, presumably by the Americans. So the de facto result of it is that no one is really going to be able to leave the Gulf. And that’s kind of where I see this game theoretically ending up.
So it seems like the result of this won’t be hugely different than what things were a few weeks ago, just with fewer Iranian ships getting out.
Also ships of those countries that negotiated transit with Iran.
If you looked at the news coming out of Asia and the diplomatic communiques of a large number of Asian states that brokered bilateral arrangements with Iran — so Pakistan, India; Bangladesh had done so; China, of course — but also countries that have otherwise fairly good links with the United States — the Philippines, Malaysia, Vietnam — all of them had essentially accepted that some payment to the IRGC was now the new cost of doing business. They were so desperately in need of energy supplies for the population that they decided to enter negotiations, even if, in principle, they would prefer freedom of navigation.
The likely diplomatic contestation or diplomatic issues coming out of this blockade are also going to be related to Asia, and that’s where I would focus our attention.
