Some symbols of global politics speak for themselves: the Berlin Wall, the atomic bomb, the dollar, the Suez Canal — each marked a seismic shift in the world order. In the 21st century, another, seemingly unlikely, symbol has joined this list: the prison. No longer just a domestic institution of justice, it’s evolving into a strategic instrument of global power — a pressure lever, a geopolitical bargaining chip, and a legal gray zone where states can act beyond conventional law.
This transformation isn’t unfolding in think-tank seminars but right in the thick of real-world politics. And its frontline is the emerging partnership between Washington and San Salvador — between the United States under Donald Trump and a small Central American nation once known only for civil war and mara gangs. Salvadoran president Nayib Bukele has offered Washington a deal that, on the surface, looks like a straightforward migration policy: take in deported migrants from the U.S. and house them in the massive CECOT prison for a fee. But beneath this transactional veneer lies something far more consequential.
El Salvador is becoming the world’s first “prison hub” — an extraterritorial penitentiary zone where questions of migration, security, international law, economics, and ideology intersect. It’s not just a response to illegal migration or gang violence. It’s an attempt to build a new global architecture of control, one in which sovereignty, borders, and human rights function very differently from the liberal order that emerged after 1945.
That evolution — from prisons as tools of domestic punishment to mechanisms of global governance — is the central question of our time. El Salvador isn’t an “exception.” It’s a prototype, one other nations may soon emulate. Which raises a deeper question:
Is the Trump–Bukele alliance creating a new model for the world order — and what will El Salvador’s transformation into a global prison hub mean for international law and the future of migration?
From Guantánamo to CECOT: The Rise of the Lawless Prison State
To grasp the magnitude of what’s happening, we need to look beyond today’s headlines about Venezuelan migrants. The concept of the “extraterritorial prison” isn’t new. It first took shape in the aftermath of September 11, 2001, when Washington built the Guantánamo Bay detention facility in Cuba — a place where detainees were neither prisoners of war nor ordinary civilians. Guantánamo existed outside the jurisdiction of U.S. courts, beyond the reach of the Geneva Conventions, and unbound by standard legal procedures.
It was more than a camp for suspected terrorists; it was an experiment in creating a legal limbo — a space where the state could act without constraints, justified by the urgency of an existential threat. The outrage Guantánamo provoked and its status as a symbol of international law’s breakdown didn’t erase one core lesson: in an era of transnational threats, states are eager to craft new mechanisms of control that don’t fit neatly into the old frameworks.
CECOT — the colossal prison opened in El Salvador in 2023 — is the direct descendant of that logic, transplanted from a military to a civilian context. If Guantánamo was built to detain “external enemies” during the global war on terror, CECOT is designed to manage “internal threats” that have gone global — illegal migration, organized crime, and transnational gangs.
The most striking innovation is that CECOT holds not just convicted criminals but also people who have never been found guilty in court. More than 75 percent of the Venezuelans deported there have no criminal record in the United States. Many were targeted based on tattoos, clothing styles, or social media posts. This isn’t traditional criminal justice — it’s a new form of preventive detention, where suspicion replaces proof and the definition of guilt becomes dangerously fluid.
El Salvador: A Test Lab for Penitentiary Geopolitics
El Salvador is a tiny Central American nation of about 6.5 million people. A decade ago, it was one of the most violent countries on earth: in 2015, the homicide rate soared to 103 per 100,000 people, and mara gangs effectively ruled entire neighborhoods. The state had all but lost its monopoly on violence.
Nayib Bukele’s rise to power in 2019 was a watershed moment. The young president launched a sweeping war on gangs: he declared a state of emergency, suspended basic due process rights, and jailed tens of thousands. Over five years, the homicide rate plummeted more than nineteenfold — down to 1.9 per 100,000. But the cost of that transformation is staggering: El Salvador is now a “prison nation,” with over 2.6 percent of its adult population behind bars — the highest incarceration rate on earth.
CECOT has become the emblem of this new reality. Built as a “Terrorism Confinement Center,” it can hold 40,000 inmates and functions as a state within a state: there are no lawyers, no family visits, no outdoor time — and no night, as the lights never go off. Originally intended for members of MS-13 and Barrio-18, CECOT now houses migrants deported from the United States as well.
Donald Trump and Nayib Bukele make little effort to hide their ideological kinship. “They say we’ve jailed thousands. I say we’ve freed millions,” Bukele declared in Washington. “You think I can use that line too?” Trump quipped in response. It was more than a joke — it captured the essence of a new era in which mass incarceration is reframed as societal liberation and the prison system becomes an exportable tool of foreign policy.
Here, El Salvador isn’t a client state but a partner. Washington pays San Salvador $20,000 per deported migrant per year. That’s the blueprint for a new model: instead of building detention centers at home, the U.S. is outsourcing incarceration abroad. If America once offshored its factories, it’s now offshoring its prisons.
Migration as the New Form of War
To understand Donald Trump’s worldview, you have to start with this premise: in his political logic, migration isn’t a humanitarian challenge — it’s a form of war. It destabilizes societies, reshapes demographics, fuels crime, and erodes national identity. And if it’s war, then the tools must be military: deportation, internment, isolation.
Over the past decade, the number of Venezuelans in the United States has surged past 900,000, according to the Census Bureau. Since 2018, Venezuelans have been the largest group seeking asylum. Among them, U.S. authorities claim, are members of Tren de Aragua — one of the Western Hemisphere’s most violent gangs — which Washington has designated a terrorist organization.
Proving anyone’s membership in such a group, however, is notoriously difficult. And that’s where a pivotal shift occurs: in Trump’s immigration policy, the presumption of innocence is replaced by the presumption of danger. It doesn’t matter whether guilt is proven — what matters is the possibility of a gang connection. That’s enough to justify deportation and incarceration.
This approach reframes immigration policy through the lens of preemptive security, echoing the logic of the “war on terror.” If a potential terrorist can be detained before committing a crime, why not a potential gang member? That’s the crux of the transformation: migration ceases to be a legal issue and becomes a national security threat.
From Borders to Prisons: The New Architecture of Control
The Salvadoran case shows just how radically the global migration order is shifting. In the 1990s and 2000s, governments tried to balance economic interests with humanitarian obligations. Today, the balance has tipped decisively toward control and containment.
Borders are becoming ever more porous for capital and technology — and ever more fortified against people. But control no longer stops at the border itself. It’s being pushed deeper — into prisons, camps, and detention centers. Inside these spaces, a new kind of geography is taking shape: legally undefined, physically sealed, and politically managed.
CECOT is no longer just a prison. It’s a “node” in a growing network of penitentiary zones that can exist outside national territory, funded by foreign governments and operating beyond their jurisdiction. If the Salvadoran model proves successful, others could follow — in Honduras, Guatemala, or Ecuador. Proposals for such hubs are already circulating.
We’re standing on the threshold of a new global system in which extraterritorial prisons are not the exception but the rule. And in this system, the key players won’t just be courts and laws, but governments positioning themselves as “landlords” for other nations’ detainees.
When Donald Trump and Nayib Bukele traded quips in the White House in March 2025 — about jailing thousands and “freeing millions” — it wasn’t just political theater. It was the articulation of a new political reality: a world where prisons are no longer domestic institutions but tools of global governance. In that world, a detainee is no longer just a criminal — they’re a commodity, a bargaining chip, a variable in international politics. El Salvador today isn’t merely a country that has locked up 2.6% of its adult population. It’s a key node in the emerging map of what might be called “penitentiary globalization.”
The Economics of Outsourced Incarceration
The logic driving this shift is brutally simple. Mass deportations from the United States have long faced two major obstacles: cost and infrastructure. Housing an inmate in a U.S. federal prison costs around $42,000 per year. Facilities are overcrowded, and new construction faces fierce resistance from local communities and environmental groups.
El Salvador offers a way out: $20,000 a year for a bed in CECOT — a facility built without regard for liberal standards or political correctness. That’s half the cost, with zero domestic political blowback. And the logic could spread quickly: if the U.S. can offload tens of thousands of unwanted migrants and offenders to El Salvador, why not strike similar deals with Guatemala, Honduras, Paraguay, or Ecuador?
What’s emerging is something akin to a “prison market” — a new form of transnational business where countries of the Global South rent out their prison capacity to nations of the Global North. This is not science fiction. According to the World Bank, there are about 11.5 million prisoners worldwide, nearly 2 million of them in the United States. America’s prison system costs taxpayers more than $80 billion annually. Reducing that burden through “prison outsourcing” could become an attractive proposition for politicians focused on cutting costs and tightening control. Today it’s a few hundred Venezuelans. Tomorrow it could be tens of thousands deported to El Salvador or other “penitentiary offshore zones.”
But the implications go far beyond economics. The rise of extraterritorial prisons undermines the very foundation of the postwar international legal order, built on universal human rights and the rule of law. Traditionally, a state is responsible for the rights of anyone it detains or deports. But by transferring detainees into another state’s jurisdiction, it effectively removes them from the reach of its own obligations. This creates a “legal gray zone” where accountability evaporates and violations seem to vanish into thin air.
CECOT illustrates this perfectly. U.S. authorities insist that the deported Venezuelans are members of a terrorist organization. Yet there’s no evidence, no trials, and the criteria for “association” often boil down to tattoos or a certain way of dressing. And still, they’re locked up for life — without lawyers, without appeals. From the standpoint of international law, this violates both the International Covenant on Civil and Political Rights and the Convention Against Torture. But who’s accountable? The U.S. claims it’s no longer responsible once deportees leave its territory. El Salvador says it’s acting within its own laws. The result is a legal limbo where a human being can be imprisoned for life without trial — and no one is to blame.
This legal vacuum makes CECOT a dangerous precedent. If transferring detainees to countries with weaker justice systems becomes normalized, it could fundamentally alter the balance of power between states and individuals in the global order. Experts are already floating ideas about “penitentiary zones” run by private companies and bilateral deals governing the detention of foreign nationals. All of this risks turning sovereignty into a tool for bypassing international law and reducing human rights to a conditional privilege, dependent on political will.
The Ideological Stakes of the Trump–Bukele Alliance
The Trump–Bukele partnership is about more than pragmatism. It’s also deeply ideological. Both leaders present themselves as opponents of liberal globalism and champions of “strong hand” governance and traditional values. Their cooperation is a manifesto of the new right-wing wave seeking to redefine the very nature of state power.
In this worldview, human rights and international institutions are not universal values but instruments of coercion imposed by global elites. By transforming El Salvador into a “prison hub,” Trump and Bukele are sending a message: an alternative order is possible — one in which the state reclaims absolute sovereignty and collective security outweighs individual rights.
The Geopolitical Reach of the Prison State
The geopolitical implications of this project stretch far beyond Central America. First, it strengthens U.S. influence in a region where Washington’s clout has waned in recent years amid growing Chinese and Russian activity. El Salvador is becoming a key American partner in security and migration policy, while Bukele secures political backing and financial resources. Second, the CECOT project could serve as a model for other states grappling with migration pressure. European governments debating refugee processing centers in North Africa are watching the Salvadoran experiment closely. In Brussels, calls are already growing for deals with third countries that would host migrants in exchange for economic aid.
But this project also has a darker side. Turning prisons into instruments of foreign policy is bound to heighten tensions with the countries whose citizens end up in such “penitentiary offshore zones.” Venezuela has already appealed to the United Nations, demanding the release of its nationals and calling their detention at CECOT illegal. If the practice spreads, similar clashes could erupt between African and European states, or between Asian nations and Australia. A new kind of diplomatic crisis could emerge — prison crises — in which the subject of negotiations is not territory or resources, but the fate of thousands detained without trial.
There’s also an internal geopolitical effect. Mass deportations and the outsourcing of detainees could bolster populist forces in the U.S. and Europe who build their platforms on anti-migrant and anti-crime rhetoric. At the same time, such policies could radicalize the communities targeted by them. In Venezuela’s case, nearly eight million people have left the country in recent years. Treating some of them as “suspects without trial” risks fueling anti-American sentiment and strengthening anti-Western movements across the region.
In the long run, this emerging penitentiary architecture could become one of the pillars of a new world order. If control over territory and sea lanes defined global power in the 19th and 20th centuries, in the 21st it may be control over the movement of people — migrants, refugees, prisoners. In this context, the prison ceases to be the endpoint of the justice system and becomes its starting point. It’s no longer just a consequence of crime but a tool for preventing it — not just punishment but policy.
This is the deeper transformation symbolized by the Trump–Bukele alliance. They’re not merely building a prison; they’re constructing a new world order in which freedom and unfreedom will be defined not just by law, but by geopolitics. In this emerging system, El Salvador isn’t a periphery — it’s a laboratory of the future, a testing ground where the state experiments with the very nature of power. The question before the international community is no longer whether this model is humane. The question is whether it will become the norm.
If the first quarter of the 21st century was dominated by debates over climate, digital revolution, and pandemics, the coming years will add another defining theme: the architecture of control over human mobility. Migration, demography, security, and law are becoming tightly interwoven, forming the backbone of a new global order. The transformation of El Salvador into an international prison hub is not a local event but a signal of a broader shift — a sign of how states in the Global North are exporting the most sensitive elements of their policy beyond their borders to manage risk and threat.
Scenario One: Institutionalizing Prison Hubs
Looking ahead to 2030, three main scenarios emerge — each with distinct risks, opportunities, and long-term consequences. The first and most likely is the institutionalization and scaling of the “Salvadoran model.” If CECOT proves effective — easing pressure on the U.S. prison system, reducing crime, and showcasing a tough immigration stance to voters — similar agreements will likely follow. OECD analysts already note that about 26 countries in the Global South have surplus prison capacity and are willing to lease it out. In Central America, that includes Guatemala, Honduras, and Nicaragua; in South America, Paraguay and Bolivia; in Africa, Uganda and Rwanda; in Asia, the Philippines and Cambodia.
Under this scenario, a new form of international cooperation would take shape: penitentiary agreements in which one state transfers not only detainees but also the responsibility for their custody to another. This would create a transnational network of prisons operating outside national jurisdictions and international conventions. For many Global South countries, it would mean hard currency and political leverage. For the Global North, it would offer a way to outsource politically sensitive functions abroad.
The risks are obvious. Such a system would incentivize mass arrests and deportations, undermine international legal standards, and pave the way for “prison diplomacy,” where detainees become bargaining chips. Bukele’s reported proposal to exchange deported Venezuelans for Maduro’s political prisoners shows just how easily a penitentiary tool can morph into a political weapon.
Scenario Two: Fragmentation and Regionalization
A less sweeping but still plausible scenario is the regionalization of the penal outsourcing model. Rather than coalescing into a fully global network, prison hubs may emerge as tools of regional control. The United States would likely deepen its cooperation with El Salvador—and perhaps rope in other Central American countries. The European Union could establish similar detention centers in North Africa, in places like Morocco, Tunisia, or Egypt, to hold undocumented migrants from the Sahel and the Middle East. Australia would double down on its offshore facilities in Nauru and Papua New Guinea. And the United Kingdom might revisit its controversial plan to deport migrants to Rwanda.
While this scenario poses fewer threats to the international order than a full-blown global carceral network, it enshrines a system of double standards in international law. UN agencies and regional courts may continue to document abuses, but in practice, states will invoke sovereignty to justify their actions. This could lead to a spike in legal conflicts, clashes over extradition, and disputes about the status of detainees. Bilateral deals would begin to eclipse universal conventions, chipping away at the framework of international human rights.
There’s also the risk of political instability in host countries. El Salvador is already showing signs of internal strain from housing thousands of foreign detainees. As the scale grows, such hubs could become flashpoints for unrest, insurgency, or tools of domestic political pressure.
Scenario Three: Pushback and Counterreaction
Then there’s the possibility of a backlash. A surge in extraterritorial prisons could provoke a robust international response. The UN High Commissioner for Human Rights has already condemned detention practices that resemble torture and criticized deportations without due process. The European Court of Human Rights is hearing cases involving prisoner transfers to third countries without proper rights guarantees. Should the CECOT model proliferate, global pressure is bound to escalate.
A political response could also take shape. Left-leaning and liberal governments in Latin America, Africa, and Europe might form a coalition to oppose what they would call “penal neocolonialism”—accusing the U.S. and its allies of using the Global South as a dumping ground for unwanted human lives. This could spark alternative proposals: UN-run detention centers, or new international conventions governing prisoner transfers.
But such resistance would require a level of global coordination that looks increasingly out of reach in today’s fractured geopolitical landscape. More likely, responses will be scattered and inconsistent—allowing the carceral model to expand, albeit under growing scrutiny.
Prisons Without Borders
What ties these scenarios together is a common conclusion: the architecture of incarceration is poised to become a central pillar of international politics in the coming years. Between now and 2030, prisons will reshape the boundary between domestic and foreign security, redefine international law, and challenge long-held assumptions about sovereignty and human rights.
For governments, institutions, and businesses, this shift brings both risks and opportunities. Navigating it will require strategic foresight—and immediate action.
Recommendations for States:
- Draft clear international prison agreements with binding safeguards for detainees, including legal representation and independent oversight mechanisms.
- Establish national systems for parliamentary and judicial review of prisoner transfers to prevent abuses and political manipulation.
- Integrate carceral diplomacy into foreign policy, especially in dealings with countries with poor human rights records.
Recommendations for International Institutions:
- The UN and Council of Europe should spearhead a new global convention on cross-border detention, setting minimum standards and assigning clear responsibilities.
- The International Criminal Court and other judicial bodies must develop frameworks for prosecuting abuses tied to offshore incarceration.
- The IMF and World Bank should tie funding for prison projects in developing nations to legal compliance and transparency benchmarks.
Recommendations for Business and Civil Society:
- Private firms involved in prison construction and management must adopt human rights compliance systems aligned with global norms.
- NGOs and advocacy groups should build cross-border coalitions to monitor extraterritorial prisons and promote transparency.
The world emerging from the alliance of Trump and Bukele is one where prisons are no longer confined to national borders—they’re becoming instruments of global power. In this world, inmates will cross borders as fluidly as capital and data. Sovereignty won’t just shield citizens; it’ll be used to detain foreigners. And human rights will shift from being guarantees to becoming bargaining chips.
The real question isn’t whether this transformation can be stopped. History shows that once control technologies are introduced, they rarely vanish. The question is whether the international community can build a framework to turn this tool from a threat into a resource. The answer will shape the global order of the mid-21st century.
