U.S. accuses Cuba of sweeping spy campaign, aiding American left

A U.S. State Department report on Monday accused Cuban spies of infiltrating the highest levels of government in Washington and aiding “left-wing terrorism” on American soil.

Containing little new information, the report, titled “Cuba: The Capital of 21st Century Communism,” comes as U.S. President Donald Trump pushes to end communist rule of the island while amping up anti-leftist rhetoric at home.

A months-long pressure campaign has seen Washington effectively impose an oil embargo on Cuba, while issuing economic sanctions against key state-run companies and even indicting the former president, Raul Castro.

Ahead of U.S. elections in November, Mr. Trump and other Republican leaders have meanwhile revived Cold War-style rhetoric portraying left-wing US political figures as a communist “menace.”

The State Department report alleged that Cuba “has infiltrated the highest reaches of the U.S. government, recruited and cultivated generations of American activists [and] backed an unprecedented wave of left-wing terrorism on American soil.”

While the allegations represent an escalation in U.S.-Cuba tensions, espionage between the two countries has long been known.

Since the Cold War, the U.S. has made high-profile arrests of Cuban intelligence officers, including the “Cuban Five” who were convicted of infiltrating civil society groups in Florida in the 1990s, and Ana Montes, who spied from a senior position within the Defense Intelligence Agency.

In more recent cases, State Department intelligence analyst Walter Kendall Myers and former U.S. Ambassador to Bolivia Victor Manuel Rocha pled guilty in separate cases to spying for the communist country.

Meanwhile, the U.S. Central Intelligence Agency (CIA) and Cuban exiles tried to assassinate late Cuban president and revolutionary leader Fidel Castro more than 600 times, his ex-intelligence chief, Fabian Escalante, once estimated.

Cuba’s Foreign Minister Bruno Rodriguez, in a post on X, called the new report “the latest fallacy from the US State Department.”

He said it was part of U.S. Secretary of State Marco Rubio’s effort to create a “pretext for sustaining a cruel and criminal economic war that punishes every Cuban family, as well as his aspiration to launch a military attack on Cuba, for which he is desperately seeking the support of US citizens.”

U.S. threatens takeover of Cuba

The report released Monday made sweeping — if unsubstantiated — allegations that Cuba has cultivated relationships with leftist groups across the world and in the U.S. to drive “overriding resentment and fundamental hatred of the United States and the broader West.”

The State Department said that the communist country had influenced “a disproportionate share of America’s most famous and influential extremist movements,” in an effort to “turn America against itself.”

The report makes the latest downturn in the long-fraught relationship.

In 2015, then president Barack Obama attempted a rapprochement with the Cuban government, hoping a more diplomatic approach would yield better relations after a half-century of hostility.

Mr. Trump quickly restored a hardline stance in 2017, and — on returning to office in 2025 — reinstated Cuba as a state sponsor of terrorism on his first day in office.

Earlier this year, the U.S. military overthrew Venezuelan president Nicolas Maduro — a long-time supporter of the Cuban government who provided subsidized energy to the island.

Since then, the United States has effectively imposed an oil embargo on Cuba that has contributed to multiple nationwide blackouts.

Trump has repeatedly signaled that the Cuban government could be next after Venezuela to fall to U.S. pressure, and said in June that Washington would be “taking over” the Caribbean island, about 90 miles (145 km) from Florida, “almost immediately.”
