What It Would Take: Cuba's Only Real Path to Power

The Superpower Audit, Episode 1, Part 2: not a smaller America — a different kind of power, built on the one asset Cuba already sells to the world.

Part 1 closed the case: 9.4 million people and shrinking, an economy that imports sugar, a grid that collapses monthly, and a military history whose finest hour was financed by somebody else. If superpower means aircraft carriers and a trillion-dollar economy, the conversation ends there.

But this series runs the extreme scenario anyway, because the exercise exposes something real. Cuba is not a generic poor island. It sits on the two doorways to the Gulf of Mexico, 90 miles from the richest market on Earth, and it already operates the most unusual instrument of influence any small country has built since 1960. Here is what the full transformation would require — and the ceiling it hits even if everything goes right.

Shift 1: The embargo reversal — the biggest single delta in this series

No other country in the Superpower Audit has a single policy change, made in a foreign capital, that would rewrite its trajectory overnight. Normalization with the United States — full trade, finance, and travel — would do for Cuba what it did for Vietnam after 1994, except faster, because the multiplier is sitting in Miami. More than two million people of Cuban origin live in the United States, already sending billions a year in remittances through a system designed to throttle them. Unthrottled, that diaspora becomes what it is in every other Caribbean economy, squared: the tourism base (Cuba's natural market is 11 million Cuban-American family visits a year, not 2.2 million total tourists), the investment class for a private sector that currently has to beg for hard currency, and a political lobby inside the superpower.

Paired with genuine market reform — property rights a foreign investor can read, a currency that isn't a fiction, private firms allowed to grow past the size where Havana gets nervous — the island's fundamentals are better than its reputation: a literate, healthy, urban population (78%+ urban), deep-water ports, and a location that makes it the natural logistics hinge between North and South America. The honest caveat from Part 1 stands: the embargo explains Cuba's isolation, not all of its stagnation. Normalization without domestic reform gets you a bigger, richer version of the same bottleneck.

Shift 2: Charge rent for the map

Every ship entering or leaving the Gulf of Mexico passes Cuba — through the Florida Straits to the north or the Yucatán Channel to the west. Every Gulf port's cargo — Houston, New Orleans, Mobile, Tampa, Veracruz, Altamira — transits water Cuba overlooks, the same geometry that makes the Strait of Hormuz worth a global crisis, at regional scale. Cuba has tried to monetize this exactly once: the Port of Mariel, a Brazilian-financed deepwater container terminal west of Havana with an attached special economic zone, built to capture transshipment traffic the Panama Canal expansion was reshuffling. It operates far below its potential, because transshipment is a trust business and embargo law makes Cuba the one Caribbean hub US-linked cargo cannot touch.

Lift the embargo and Mariel becomes a serious asset: the closest deepwater port to the US Gulf and East Coast that isn't in the United States, paired with a free zone aimed at exactly the nearshoring wave now reshaping Mexico's economy. Geography gave Cuba a tollbooth. Only politics keeps the barrier down.

Shift 3: Scale the weapon it already has

Cuba's medical internationalism is usually filed under soft power, which undersells it by about $5.3 billion a year — the missions' estimated 2024 earnings, roughly half of all Cuban exports, per economist Ricardo Torres. At their peak a decade ago they earned closer to $8 billion. Around 24,000–26,000 Cuban health workers are currently posted abroad; when St. Lucia's prime minister says his country's medical system "would basically collapse" without them, that is not sentiment, it is structural dependence — the raw material of leverage, created in clinics rather than carrier groups.

Now run it forward as strategy rather than improvisation. The world is aging exactly the way Cuba already has: by 2050 one in six humans will be over 65, and the binding constraint on every rich country's healthcare system is trained people. Cuba manufactures trained people as a national industry — it has one of the highest physician densities on Earth (roughly 8–9 doctors per 1,000 people, several times the US figure) — and it pairs the export with biotechnology that can travel on its own: BioCubaFarma's vaccines and biologics, an institution that developed COVID vaccines under embargo and licensed production to Iran and Vietnam. A Cuba that doubled down — contract vaccine manufacturing for the Global South, medical universities training foreign students at scale on the ELAM model, telemedicine brigades bundled with its own biotech products — would hold a genuinely scarce global asset.

The vulnerabilities are real and need naming, because Part 2 scenarios fail on details: the missions depend on host governments paying and on Havana's wage arrangements, which critics — including the US government, now actively pressuring host countries — call exploitative; doctors defect; and the whole model competes with the island's own collapsing hospitals for staff. A weapon that embarrasses you at home is a wasting asset. But as the foundation of a small state's power, it is more original than anything else in this series.

Shift 4: Fix the fuel, or nothing else matters

Every scenario above assumes electricity. Cuba's actual 2026 is a grid that has collapsed nationwide at least a dozen times since October 2024, running largely on 1960s–70s oil-fired plants and imported fuel that patrons keep failing to deliver. The turnaround path is visible, and interestingly, already started: Havana claims roughly 1.4 GW of solar capacity installed across 144 parks by mid-2026 with renewables above a fifth of generation, built substantially with Chinese equipment — the first energy asset Cuba has ever had that no blockade can interdict once the panels are bolted down. Add the offshore question honestly: the US Geological Survey has estimated the North Cuba Basin could hold on the order of 4.6 billion barrels of undiscovered oil, but the deepwater wells drilled in 2012 by Repsol, Statoil, and Gazprom Neft all came up non-commercial. Offshore oil is a lottery ticket, not a plan. Solar plus storage plus a grid rebuilt for an island's scale is the plan — unglamorous, financeable, and the precondition for the biotech labs and container terminals above ever running at capacity. Nickel and cobalt — Cuba holds world-scale reserves of both — become the second engine only with sanctions relief and Western buyers; treat them as upside, not foundation.

Shift 5: The Caribbean as a bloc, the doctors as the glue

Cuba cannot lead Latin America; Brazil and Mexico are too big and too uninterested. It can plausibly anchor the Caribbean — fifteen island states whose health systems, disaster response, and increasingly whose votes in international forums already run partly through Havana. Hurricanes make the case annually: Cuba's civil defense and medical brigades are the region's de facto emergency service. A formalized version — a Caribbean health and resilience compact, funded partly by the diaspora and partly by the climate finance the islands collectively bargain for — converts goodwill into an institution, and an institution is what separates influence from nostalgia. Layer on the asymmetric niches Cuba has historically been good at — signals intelligence from its geography (the Lourdes facility once listened to half the hemisphere for Moscow), cyber capability, and diplomatic cadres that consistently outperform the island's size at the UN — and you get the realistic shape of Cuban power: regional, specialized, and very hard to ignore.

The honest ceiling

Stack every shift — normalization, reform, Mariel humming, solar grid, doubled medical-biotech exports, a Caribbean compact — and run it for thirty years. Cuba becomes prosperous. It becomes the Caribbean's indispensable state. It does not become a superpower, because the one input no policy can conjure is people: starting from 9.4 million, aging, and emigrating, even heroic demographic success means a country of perhaps 10–11 million in 2050, in a world where the superpower threshold starts at economies forty times its size. The math from Part 1 does not bend.

But measured on its own terms — which is how this audit closes every episode — the endgame is not failure. It is a country that looked at what it could actually be best in the world at, mass-producing physicians and vaccines on an island with no oil and no money, and built the prototype decades early, under siege conditions. The full-strength version of that model, properly fueled and properly paid for, is a niche superpower in the one sector the whole planet is aging into.

Verdict: Superpower ceiling — foreclosed by demography. Own-terms grade — the model was never the problem; the fuel was. Next in the audit: Indonesia, the one country in this season whose path to the top five doesn't require a miracle — just nickel, chokepoints, and 284 million people.
