The Cuban government has rejected the United States’ accusations that it deployed troops to Ukraine, calling the claim “unfounded” and politically motivated, according to Reuters. Early this October, a leaked U.S. State Department cable alleged that between 1,000 and 5,000 Cuban nationals were fighting alongside Russian forces, making Cuba the second-largest foreign contingent after North Korea. Cuba’s Foreign Ministry countered that no state forces had been sent, and released information on legal proceedings against Cuban citizens charged with mercenarism. According to the ministry, eight trials have been held, with five resulting in 26 convictions and several others pending. The Cuban foreign ministry insists it maintains “zero tolerance for mercenarism, trafficking in persons and the participation of its nationals in any armed confrontation abroad.” Reports of Cubans on Ukrainian battlefields first surfaced in 2023, prompting Havana to investigate. The government argues these cases involve individuals deceived by criminal networks rather than any state-sponsored deployment.

The controversy comes as the United Nations General Assembly prepares to vote on its annual non-binding resolution urging Washington to lift its decades-long economic embargo on Cuba. The measure has passed by overwhelming margins every year since 1992, with only the United States and Israel opposing it. The embargo, first imposed in 1962 after the Cuban Revolution and the nationalization of U.S.-owned assets, remains one of the world’s longest-running sanctions regimes. It bans most trade, financial transactions, and investment between the two countries, restricts travel, and penalizes foreign firms that do business with Havana. According to Cuban government estimates cited in United Nations (UN) reports, the embargo has cost the island more than $150 billion in cumulative losses, cutting off access to credit, technology, and essential imports. In the 2023, UN Secretary General’s report on the Necessity of Ending the Economic, Commercial and Financial Embargo Imposed by the United States of America against Cuba estimated that the embargo had caused $1.3 trillion in cumulative losses when adjusted for the depreciation of the U.S. dollar against gold. While Washington defends the embargo as pressure for political reform, it has also caused chronic shortages, economic stagnation, and humanitarian strain.

The timing of the latest U.S. allegations suggests a broader diplomatic strategy. For Havana, it reinforces the perception that Washington is using the Ukraine conflict to justify its continued isolation of Cuba on the world stage.

The dispute is complicated by conflicting intelligence and politicized interpretations. BNE IntelliNews cites Ukrainian intelligence estimates of 6,000 to 7,000 Cuban nationals fighting in Ukraine, while Kyiv’s “I Want to Live” initiative has verified only 1,028 signed contracts. Some U.S. officials have claimed as many as 20,000 recruits since 2022. The wide range of figures points to a lack of verifiable proof, and highlights how easily intelligence can be shaped to fit political agendas. 

Meanwhile, investigations by Radio Free Europe/Radio Liberty point to a sole perpetrator at the center of mercenary recruitment. In August 2023, two 19-year-olds, Alex Vega and Andorf Velasquez, spoke from a hospital in Russia’s Kaliningrad region about how they were lured to Russia under false promises of construction jobs. They told a Cuban video blogger they traveled “to make some money,” led by two Russian women and one Cuban intermediary. Once in Moscow, they said they were forced to sign a Russian-language contract they could not read, and sent to the provincial city of Ryazan, where they were housed in a dormitory before being dispatched to the front lines to dig trenches. Both were later wounded in battle (RFE/RL, August 2023). Further investigation by RFE/RL’s Systema unit identified Yelena Smirnova, a 41-year-old travel agent from Ryazan, as a key figure behind a recruitment ring that allegedly processed over 3,000 foreign fighters. According to her lawyer’s letter obtained by the outlet, Smirnova’s network used social-media ads offering high-paying construction work to attract recruits who later discovered they were being sent to fight. Ukrainian lawmaker Oleksandr Zablotskiy told RFE/RL he believed the operation ran in connection with Russia’s FSB and GRU intelligence services, stating: “tour operators have traditionally served as a cover for logistics… We see recruitment by FSB and GRU agents whose identities are reliably known.”

These accounts point to a system of coercion, not enlistment. Many Cubans—facing unemployment, inflation, and food scarcity made worse by the embargo—appear to have been manipulated by false promises of legal work abroad.

Cuba’s government, while condemning mercenarism, has acknowledged it cannot determine how many citizens are fighting “on either side” of the conflict. Its prosecutions show intent to curb the practice, yet transparency remains limited. The U.S., for its part, has used these claims to bolster its long-standing policy of economic pressure. Kyiv Post reported that an October 2 U.S. State Department memo directed American diplomats to oppose the upcoming UN vote lifting the embargo—a move consistent with the Trump administration’s strategy of maximum pressure. According to the paper, the policy is heavily influenced by Secretary of State Marco Rubio, whose base among Cuban-American voters in Florida favors a tough stance toward Havana. In this context, the “Cuban fighters” narrative functions as both propaganda and a political tool, damaging Havana’s credibility abroad while providing Washington with a convenient justification for a policy that has endured for six decades despite global opposition.

With decades of mistrust now threatening cooperation, both Washington and Havana would benefit from an increased capacity for verification and transparency. 

Cuba and Russia should invite a UN-mandated investigation, ideally through the Office of the High Commissioner for Human Rights, to examine claims of forced recruitment and human trafficking. Allowing neutral observers to review travel records, contracts, and court files would demonstrate Cub’as sincerity about its “zero-tolerance” stance and clarify whether the networks that exploited Cuban citizens operated independently or under official neglect. Building on the findings reported by Radio Free Europe, Cuba should also form a bilateral task force with Russia to vet job agencies, monitor visas, and guarantee that all overseas employment contracts are translated and voluntary. Such mechanisms would directly prevent the kind of deception that trapped young Cubans like Alex Vega and Andorf Velasquez, who illustrate the human cost of geopolitical hostility—two teenagers deceived by poverty into a war they neither chose nor understood. Preventing such exploitation requires not more sanctions or suspicion, but sustained clarity, international oversight, and diplomacy rooted in empathy rather than enmity.

At the same time, the United States must reframe its policy toward Cuba around humanitarian cooperation rather than punitive isolation. After six decades, the embargo has failed to achieve its aims, instead worsening living conditions for ordinary Cubans. A gradual easing of sanctions tied to verifiable anti-trafficking and transparency benchmarks would reward progress instead of perpetuating poverty.

The controversy exposes a deeper flaw in modern diplomacy: nations are quick to trade blame but slow to protect people. When economic coercion meets exploitation, truth itself becomes collateral damage. Building peace will mean rejecting that cycle and choosing transparency and empathy over propaganda and power politics, before another generation is lost to someone else’s war.
