Argentine political scientist Atilio Boron, 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 explained 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 graveyard of your political career," wrote Boron on his X account.
The message came in response to the reactions from the Cuban government and its allies regarding recent statements by Rubio on 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 get out of the knot, we tighten it," Rubio stated.
The official 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 persist for "the next two and a half years," referring to the remaining time of 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.
"Years of clucking that the blockade doesn't exist, that 'the regime' doesn't work, that the State is 'failed'... And now they admit that they want to suffocate us, and that every time this country finds a way to move forward, they close it off. How miserable!", wrote Hernández Nordelo on X.
It was precisely in response to Hernández Nordelo's publication that Boron raised the tone of his criticisms this Sunday, addressing the Secretary of State directly.
Boron has maintained a strong political identification 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 toward 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 progressively increase pressure and make it more difficult for the Cuban government to find ways to circumvent it.
The regime has reacted by accusing Washington of attempting to provoke a further deterioration of the island's economic situation.
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 as far as to accuse the Secretary of State of preparing a "pretext" for a potential military aggression, while also holding him responsible for promoting policies harmful to Cubans living in the United States.
Rubio, for his part, has insisted that the root of the Cuban crisis cannot be separated from the current political model on the island.
"The government system in Cuba needs to change", asserted the Secretary of State, who maintains that a profound economic transformation is unfeasible as long as the political structure of the regime remains intact.
