Secretary of State Marco Rubio says Cuba poses a national security threat to the US.
Published On 22 May 2026
United States President Donald Trump and Secretary of State Marco Rubio have issued new threats of military action against Cuba.
Rubio told reporters late on Thursday that Cuba has been a national security threat for years because of its ties to US adversaries Russia and China, while Trump said he is likely to be the president to finally take action.

The Trump administration, with Cuban-American Rubio at the forefront, has been raising the pressure on the communist-led island in an apparent bid to institute “regime change,” including a fuel blockade that has put the Cuban economy on the edge of collapse.
The push has accelerated in recent days, with the US indicting Cuba’s former President Raul Castro and gathering military forces in the Caribbean.
Rejecting suggestions of “nation building,” Rubio told reporters the issue is one of “national security”. He added that while a negotiated agreement is the US “preference”, the path of diplomacy with Cuba is “not high”.
“Their economic system doesn’t work. It’s broken, and you can’t fix it with the current political system that’s in place,” Rubio said.
Over the years, Cuba has gotten used to “buying time and waiting us out,” Rubio said. “They’re not going to be able to wait us out or buy time. We’re very serious, we’re very focused.”
Separately, President Donald Trump told reporters that US presidents have considered intervening in Cuba for decades, but that it looks like he will be “the one that does it”, adding that he would be “happy” to do so.
In response, Cuban Foreign Minister Bruno Rodriguez lambasted Rubio for falsely labelling Cuba a threat.
“The US secretary of state lies once again to instigate a military aggression that would provoke the shedding of Cuban and American blood,” Rodriguez said.
Raised tension
Since returning to office, Trump has slapped Cuba with numerous sanctions, implemented a fuel blockade and overseen a military build-up in the region.
The renewed threats on Thursday came amid rising tensions between the countries.
The US indicted Cuba’s former President Raul Castro on Wednesday, in connection with the 1996 downing of a plane.
On Thursday, Adys Lastres Morera – sister of a high-ranking executive of the Grupo de Administracion Empresarial SA (GAESA) conglomerate, which is controlled by Cuba’s military and controls large swaths of the economy – was arrested.
More sanctions were imposed on the Cuban government in the past week. The US military announced that several navy ships, including an aircraft carrier, had arrived in the Caribbean on Wednesday to take part in maritime exercises with partners in Latin America.
Rubio has noted that Cuba had earlier tentatively accepted an offer of $100m in aid in return for reforms. But he said it was unclear if the US would accept Cuba’s terms, as Washington insists on circumventing the military-backed conglomerate GAESA.
Analysts caution that Trump and Rubio are eyeing a similar course of action in Cuba to the regime change manufactured in Venezuela. Left-wing President Nicolas Maduro and his wife were kidnapped in a military operation in January. They were taken to the US, where Maduro was charged with “narcoterrorism”.
Rubio insists that Cuba poses a serious national security threat to the US because of its security and intelligence ties with China and Russia.
Both countries have criticised the US pressure on the island.
China said on Friday it “firmly supports” Cuba and urged the US to de-escalate tensions and “stop threatening force”.
Kremlin spokesperson Dmitry Peskov said: “We believe that under no circumstances should such methods – which border on violence – be used against either former or current heads of state.”
