IN CASE YOU MISSED IT... Rep. Mario Díaz-Balart in Newsweek: Cuba's Terror Network and Its Role in Russia's War

WASHINGTON, D.C. – U.S. Rep. Mario Díaz-Balart (FL-26) co-authored an op-ed alongside Markus Wiechel, a member of the Swedish Parliament, on the Cuban regime's long history of supporting terrorist groups and adversaries, including its active role today in one of the most urgent security threats: Russia's war against Ukraine.

Since 2022, thousands of Cuban nationals have been deployed as mercenaries for Putin. This scale of involvement is not possible without the Cuban regime’s approval and fits a decades-long pattern: harboring U.S. fugitives, aiding the FARC and ELN, propping up Venezuela’s dictatorship, collaborating with Iran and North Korea, and running cyber and disinformation operations across the hemisphere.

In Cuba, where vibrant streets hide daily struggles, the government silences its people and spreads trouble worldwide. For over 60 years, since the revolution, the regime has crushed free speech at home and backed violent groups abroad. There’s clear evidence that Cuba supports terrorism, yet many countries hesitate to act. Calling Cuba a "state sponsor of terrorism" isn’t just a label—it’s a vital step to stop their dangerous actions and protect democracies everywhere.

The proof is undeniable. Since the 1960s, the Cuban dictatorship has supplied weapons, training and safe hideouts to rebel groups causing chaos in Latin America. Groups like the FARC and ELN in Colombia—labeled terrorists by the U.S. and Europe—have relied on Cuban communist support for years. The Cuban regime has hosted talks for one of these groups, but not as an honest broker—they shielded leaders even after a 2019 bomb attack in Bogotá that killed 22 people and injured over 60. Cuban communist agents even work inside Venezuela’s government, propping up its dictatorship and creating a hub for criminals.

The Cuban regime’s actions go further. They shelter U.S. fugitives wanted for serious crimes by letting these criminals live freely in Cuba, encouraging violence that stretches from U.S. cities to Colombia’s mountains.

The dictatorship also runs online attacks, spreads false information, and works with countries like Iran and North Korea, making threats worse by mixing terror with economic pressure.

The communist regime’s role in Russia’s war against Ukraine makes things even clearer. Since the full-scale invasion of Ukraine in 2022, thousands of Cubans have been sent to fight for Russia as mercenaries. Some estimates say that the number of Cuban fighters within Russian ranks could be as high as 20,000.

The Cuban dictatorship denies involvement, but experts say this couldn’t happen without the government’s approval. By supporting Russia’s attacks—bombing Ukrainian schools and hospitals—Cuba is fueling a war that’s a form of state-backed terror, hurting innocent people far away.

The U.S. recognized this threat and returned Cuba to the terrorism sponsor list, citing its meddling in Venezuela and beyond. It is now time for the rest of the free world to speak the truth about this barbaric regime.

This is why we push for governments across the world to acknowledge that the Cuban regime is a state sponsor of terrorism, as stated in our written declaration in the Parliamentary Assembly of the Council of Europe.

Democracies need to stand united, and it is crucial not to look away. The people of Cuba and Ukraine deserve our strong support.
