US Tightens Blockade Against Cuba

In the stillness of a Havana night, the only sounds are the hum of a generator at a distant hospital and the murmur of a family gathered in candlelight. For them, “U.S. national security” is not an abstract concept debated on American cable news; it is the tangible reality of a 20-hour blackout, the smell of spoiled food and the fear for a child’s refrigerated medicine. This is the face of a policy that the United States government calls a response to an “extraordinary threat.” The true threat, however, is not military. It is the 67-year defiance of a small island nation that has refused to relinquish its sovereignty.

On Jan. 29, the Trump administration transformed a long-standing campaign of pressure into a blunt instrument of suffocation. With an executive order, it weaponized the U.S. tariff system against any nation, including countries like Mexico, that dares to sell oil to Cuba. This is no longer about isolating or containing the Cuban people from the rest of the hemisphere; it is a deliberate strategy of total economic asphyxiation, a move unseen in its aggression since the Cold War.

The machinery of suffocation

Cuba’s electrical grid, water pumps, public transport, hospitals and schools run on imported fuel. By coercing third countries, the U.S. aims not merely to sanction but to disrupt a nation’s very metabolism. The Cuban government’s statement cut to the core: This is “blackmail, threats and direct coercion” designed to prevent fuel from entering the country. The result is collective punishment, a violation of international law that uses hunger, darkness and disease as political weapons to break the will of a people.

A constant war: The imperial playbook from Eisenhower to Trump

To call this a “foreign policy” is to undersell its nature. It is an evolving, multilateral instrument of war, relentlessly pursued by 10 consecutive U.S. presidencies with a single goal: the destruction of Cuba’s socialist project. Among them:

• Dwight Eisenhower (1960) initiated the aggression with the first blockade after Cuba nationalized U.S.-owned refineries.
• John F. Kennedy (1961-63) escalated with the failed Bay of Pigs invasion, made the blockade total and greenlit Operation Mongoose, a secret program of sabotage and attempted assassination of Cuban leaders, including over 630 attempts against Fidel Castro.
• Bill Clinton (1992-1996) delivered what was hoped to be a “knockout blow” after the Soviet Union’s fall, signing the Torricelli and Helms-Burton acts. These laws extended the U.S. blockade extraterritorially, punishing foreign companies for trading with Cuba and asserting U.S. authority over global commerce.
• Trump (2017-21; ’25-), after a fragile thaw under Barack Obama, not only reversed course but plunged deeper into cruelty. He added Cuba back to the “state sponsors of terrorism” list, a move widely condemned as political fiction, and enacted 243 new sanctions. His most recent act, the 2026 executive order, seeks to seal the island’s fate by starving it of energy.

The strategy has always been naked in its intent. A declassified 1960 State Department memo by Lester D. Mallory advocated creating “hunger, desperation and overthrow of government” by denying “money and supplies.” The human cost is the point, not a side effect.

The “brutal dilemma” and its human toll

This engineered crisis has measurable, horrific consequences. By the 1990s, the tightened blockade caused a 40% drop in caloric intake and a 48% surge in tuberculosis deaths among Cubans. Today, it blocks the purchase of medical ventilators, spare parts for water purification and, crucially, the fuel to power them.

This suffering is framed as a necessary sacrifice by members of the Cuban American mafia that serve in the U.S. Congress. Rep. Maria Elvira Salazar, R-Fla., recently articulated the chilling calculus: “It’s devastating to think about a mother’s hunger, a child who needs immediate help .… But that is precisely the brutal dilemma we face … : to alleviate short-term suffering or to free Cuba forever.”

This promised “freedom” is a return to the pre-1959 past, when U.S. corporations controlled 80% of Cuba’s public utilities and 70% of all arable land. It is the “freedom” to exploit, purchased with the calculated suffering of an entire generation.

The “Donroe Doctrine”: imperialism unleashed

Trump’s escalation is the cornerstone of his administration’s “Donroe Doctrine,” a 21st-century revival of the 1823 Monroe Doctrine that declares the whole of Latin America and the Caribbean to be U.S. property. Following the illegal attack of Jan. 3 on Venezuela, Trump stated plainly: “American dominance in the Western Hemisphere will never be questioned again.” Under this doctrine, any nation that chooses an independent path, especially one organizing its economy for human need, like Cuba’s world-renowned health care system, is deemed a “national emergency.”

The war abroad and the war at home

For the American people, it is critical to see this not as a distant issue but as part of a continuous logic. The same administration that invokes “national emergencies” to strangle Cuba’s economy uses “emergencies” to unleash ICE raids in U.S. cities and kill its own citizens like Renee Good and Alex Pretti. The same mindset that labels 11 million Cubans a collective threat for practicing self-determination labels migrants and minorities as domestic threats. The logic of the blockade and the logic of the border are one and the same: the violent control of populations and resources, and the designation of entire groups of human beings as disposable.

The flickering candle in that Havana home, then, is more than a light against the darkness. It is a defiance of an imperial order. The struggle of the Cuban people to keep their lights on is a fundamental struggle for the right of all peoples to determine their destiny, free from the coercion of an empire that confuses dominance with security, and mistakes cruelty for strength. As in the past, Cubans will collectively rise to the challenge in order to not only survive, but overcome the blockade.
