The United States allowed the ship through. Donald Trump, speaking aboard Air Force One, said he had "no problem" with Russia or anyone else sending oil to Cuba "right now." This is the same president who imposed the blockade in January, who threatened punitive tariffs on any nation that sold oil to Havana, and who publicly mused about a "friendly takeover" of the island. The reversal was not explained. It did not need to be. The explanation is visible from orbit.

The Blockade Nobody Called a Blockade

On January 3, the Trump administration imposed what amounted to a de facto fuel embargo on Cuba. The trigger was the US-backed removal of Venezuelan President Nicolás Maduro, which severed Cuba's primary energy lifeline in a single stroke. Venezuela had been supplying Cuba with subsidised oil for over two decades, a pillar of the relationship between Havana and Caracas that predated both the current Cuban and Venezuelan governments in spirit, if not in name.

With Maduro gone and a US-aligned government installed in Caracas, the oil stopped. Washington then made it clear that any country attempting to fill the gap would face consequences. Tariffs. Sanctions. The full weight of American economic leverage deployed not against a military adversary, but against an island of fewer than ten million people whose electrical grid was already failing.

The administration never used the word "blockade." Legally, a blockade is an act of war, and the United States has maintained since 1962 that its measures against Cuba constitute an "embargo," not a blockade, a distinction that matters in international law even if it means nothing to the family sitting in the dark in Havana.

But call it what you want. When one country uses its military and economic power to prevent fuel from reaching another country's civilian population, the technical vocabulary matters less than the result. The result was darkness. Hospitals running on failing generators. Food spoiling without refrigeration. An entire nation's infrastructure grinding toward collapse, not from war, not from natural disaster, but from policy.

The Ship and the Escort

The Anatoly Kolodkin left the Russian port of Primorsk on March 8. A Russian naval vessel escorted it through the English Channel. The British Royal Navy dispatched HMS Mersey and a Wildcat helicopter to track it, which is the kind of detail that sounds like a Cold War novel but is simply what happened.

The tanker is under US sanctions. Russia is under US sanctions. Cuba is under US sanctions that predate the current president, his predecessor, and most of the people reading this. The fact that a sanctioned vessel carrying sanctioned oil to a sanctioned country required explicit American permission to complete its journey tells you everything about the architecture of global trade in 2026. The sea lanes are technically international. The permissions are American.

And the permission was granted. Not through a formal policy reversal, not through diplomatic channels, not through legislation, but through a remark on an airplane. The US Coast Guard was briefed. The ship was let through. The blockade, which was never called a blockade, was lifted in the way it was imposed: by one man's word.

The Quiet Part

Earlier this month, the United States temporarily eased sanctions on Russian energy exports. The stated reason was to stabilise global oil markets disrupted by the US-Israel war with Iran. The actual effect was broader. When you loosen the pressure on Russian oil to manage one crisis, the looseness does not confine itself to the crisis you intended. It flows, like oil does, toward wherever there is demand.

Cuba is demand. Cuba has been demand for three months, demand so acute that the entire country has gone dark on multiple nights, demand that has driven what remains of the island's middle class further into poverty and pushed the poorest into conditions that humanitarian organisations have described in language usually reserved for conflict zones.

The easing of Russian sanctions gave Washington a way to let the tanker through without admitting it was letting the tanker through. Russia sends oil to Cuba. The US does not block it. Trump says he has "no problem" with it. The framing is generosity, or at least indifference. The reality is that the administration created a humanitarian crisis, maintained it for twelve weeks, and is now permitting its partial relief as a byproduct of an unrelated geopolitical calculation about Iran.

Nobody in Washington is saying: we starved Cuba of energy for three months and it achieved nothing. That is what happened. But admitting it would require answering the question that American Cuba policy has been avoiding since 1962: what is the objective, and is any of this achieving it?

Sixty-Four Years of the Same Question

The United States has maintained economic restrictions on Cuba for sixty-four years. The original objective was the removal of the Castro government. Fidel Castro died in 2016. His brother Raúl retired in 2021. The government remains. The embargo remains. The stated objectives have shifted over the decades, from anti-communism to human rights to democracy promotion, but the instrument has not changed, and neither has the outcome.

Cuba is poorer than it would otherwise be. That is not in dispute. The embargo has cost the Cuban economy hundreds of billions of dollars over six decades, by Havana's estimates, and even conservative external assessments put the figure in the tens of billions. The Cuban government uses the embargo to explain every failure of its own economic management, and it is not always wrong to do so, which is precisely the problem. An external pressure that the target government can credibly blame for domestic suffering is not leverage. It is a gift.

Every US administration since Kennedy has faced the same question: is the embargo working? The answer has been no for decades. But ending it would require a political courage that no president has been willing to spend, because the domestic politics of Cuba policy, concentrated in Florida, have always outweighed the strategic logic.

Trump is not Kennedy. This is true, but not in the way the comparison is usually intended. Kennedy imposed the embargo as part of a Cold War strategy that, whatever its moral failures, had an internal coherence. Cuba was a Soviet ally 90 miles from Florida, and the embargo was one instrument in a broader containment architecture. That architecture no longer exists. The Soviet Union is gone. The Cold War is over. Cuba is not a strategic threat to anyone. It is a Caribbean island with a failing power grid, and the United States is managing its energy supply the way a landlord manages heat in a tenement, turning it off to make a point and then turning it back on when the complaints get loud enough.

The Humanitarian Arithmetic

For three months, 9.6 million people lived with the consequences of a policy that served no discernible strategic purpose. The blackouts were not incidental. They were the mechanism. The theory, never stated openly, is that enough economic pain will cause the Cuban people to rise up against their government, or cause the government to collapse under its own weight. This theory has been tested for sixty-four years. It has not worked. It has produced suffering. It has not produced change.

The people who lose power when the grid goes down are not government officials. They are not military officers. They are elderly people in apartments without air conditioning. They are patients in hospitals where the backup generators run for hours, not days. They are parents trying to keep food from spoiling in a country where food is already scarce. The cost of the blockade is measured in human misery distributed with perfect regressivity, falling hardest on those with the least.

And now a Russian tanker is bringing 730,000 barrels of oil, enough to provide some relief for some period of time, and the man who ordered the blockade says he has "no problem" with it. The reversal is not compassion. It is not strategy. It is the sound of a policy that has no theory of success bumping into a reality it cannot ignore without embarrassment.

What the Tanker Reveals

The Anatoly Kolodkin is not a geopolitical masterstroke by Moscow. Russia has been supplying oil to Cuba intermittently for years, sometimes as a favour to an old ally, sometimes to irritate Washington, sometimes because a transaction is a transaction. The shipment is significant not because of what Russia gains, but because of what it exposes about American power and its limits.

The United States can blockade Cuba. It has the naval capacity, the economic leverage, and the legal framework to prevent almost any commercial vessel from reaching the island. It did exactly that for twelve weeks. And at the end of those twelve weeks, it let a Russian tanker through because the alternative, maintaining a humanitarian crisis that was generating international condemnation while achieving nothing, was more embarrassing than the reversal.

This is what the decline of coherent strategy looks like. Not weakness in the traditional sense, not a lack of aircraft carriers or sanctions infrastructure, but an inability to connect means to ends. The United States can exert enormous pressure. It can cause enormous suffering. What it cannot do, and has not been able to do for sixty-four years, is explain what the suffering is for.

Kennedy could explain it. You might disagree with his explanation, but it existed. It had a logic. It connected to a worldview. Today the explanation is: because we always have. Because Florida. Because no president wants to be the one who "lost" Cuba, a phrase that makes no sense when you examine it, because Cuba was never America's to lose, but which carries enough political weight to sustain a policy that has outlived every justification ever offered for it.

A Russian tanker is sailing to Cuba with American permission. The blockade blinked. It will blink again, or it will not, depending on what is convenient. That is not foreign policy. It is reflexive muscle memory from an empire that has forgotten why it clenched its fist in the first place.
