Argentinian political scientist Atilio Borón, known for his support of the Cuban regime, lashed out this Sunday at U.S. Secretary of State Marco Rubio, warning him that "Cuba will be the grave of your political career," after the official outlined the Trump administration's pressure strategy against Havana.
“Marco, rest assured that with all the suffering you have caused the Cubans, Cuba will be the grave of your political career,” Boron wrote on his X account.
The message came in the midst of reactions from the Cuban government and its allies to recent statements made by Rubio regarding Trump's strategy towards Cuba.
The controversy began after an exclusive interview given by Rubio to Axios, in which the Secretary of State openly described Washington's policy of closing off avenues that would allow the Cuban regime to ease U.S. economic pressure.
"Every time they create a new mechanism to untie the knot, we tighten it," Rubio stated.
The Secretary of State also stated that the United States aims to make it clear to Havana that "there are no escape valves" and warned that the strategy will remain in place for "the next two and a half years," referring to the time remaining in Trump's current term.
The words provoked an angry response from Gerardo Hernández Nordelo, national coordinator of the Committees for the Defense of the Revolution (CDR) and member of the Council of State of Cuba. "For years they have clucked that the blockade doesn't exist, that 'the regime' is not functioning, that the state is 'failed'... And now they acknowledge that they want to suffocate us, and that every time this country finds a way to move forward, they shut it down. Miserable!" Hernández Nordelo wrote on X.
It was precisely Hernández Nordelo's publication that Borón responded to this Sunday, raising the tone of his criticisms and addressing the Secretary of State personally.
Borón has maintained a close political affiliation with the regime in Havana for decades and has publicly defended the so-called Cuban Revolution on numerous occasions.
The statements against Rubio come as the Trump administration intensifies its strategy towards Havana.
According to the interview given by the Secretary of State to Axios, Washington has adopted more than two dozen measures related to Cuba since January 2026, including sanctions against entities and individuals linked to the regime.
Rubio made it clear during the conversation that the U.S. strategy does not aim to provide new concessions to Havana, but rather to gradually increase pressure and make it difficult for the Cuban government to find ways to evade it.
The regime has reacted by accusing Washington of seeking to further deteriorate the economic situation on the island.
The Cuban Foreign Minister, Bruno Rodríguez Parrilla, has repeatedly criticized Rubio, accusing him of lying about Cuba and using his statements to justify an increasingly aggressive policy against Havana.
In July, Rodríguez went so far as to accuse the Secretary of State of preparing a "pretext" for a possible military aggression, in addition to holding him responsible for promoting policies harmful to Cubans residing in the United States.
Rubio, for his part, has insisted that the root of the Cuban crisis cannot be separated from the political model currently in place on the island.
"The political system in Cuba must change", stated the Secretary of State, who argues that a deep economic transformation is unfeasible as long as the political structure of the regime remains intact.
