Marco Rubio is poised to reshape the United States’ approach to Cuba at a critical juncture, as the Trump administration seeks to redirect focus from stagnant negotiations with Iran. With the potential to destabilise the 67-year-old regime in Havana, Rubio’s efforts could significantly influence American influence across the Western Hemisphere.
A Personal Mission
For Rubio, the son of Cuban immigrants, this campaign against the Cuban regime is not merely a policy initiative; it is the culmination of a decades-long personal quest. As both Secretary of State and National Security Adviser, he has positioned himself as a pivotal figure within the Trump administration, leveraging his role to promote a vision of American authority in Latin America.
In a recent address coinciding with Cuba’s independence day, Rubio asserted in Spanish that the ongoing embargo is not the source of the island’s hardships. He emphasised that the real impediment to a brighter future for Cubans lies in the hands of their current leaders. “Currently, the only thing standing in the way of a better future are those who control your country,” he declared.
A close associate remarked, “All roads have been leading to Cuba for Rubio. He has wanted this for a long time and now he finally has the authority to reach that goal.”
Military Posturing and National Security Claims
The Trump administration has initiated military maneuvers in the region to reinforce its stance against Cuba. Notably, the USS Nimitz and its strike group have been deployed to the southern Caribbean Sea, signalling a show of force against the Cuban government. Administration officials are framing Cuba as a national security threat, alleging that the regime has acquired over 300 military drones, potentially to target US bases or vessels.

Rubio has actively participated in this narrative, asserting that Cuba not only possesses weapons from Russia and China but also hosts foreign intelligence operatives. “Havana poses an imminent national security threat to the US,” he warned during a recent press briefing.
These claims have sparked skepticism among Democrats, particularly given the tumultuous context surrounding US military engagements abroad. Senator Chris Murphy expressed concerns regarding the potential for a pretext to justify further military intervention, cautioning against the influence of hawkish advisors around the President.
A Shift in Foreign Policy
Rubio’s ascent coincides with a notable shift in the Trump administration’s foreign policy, which appears increasingly inclined towards military intervention. While initially promising a focus on domestic priorities, the administration’s recent actions in Venezuela marked a decisive turn towards aggressive foreign engagement. Observers suggest that this new approach mirrors the hardline stances Rubio advocated during his own presidential campaign.
Matthew Kroenig, a prominent foreign policy analyst, remarked, “The kind of foreign policy Trump is carrying out right now is not that different from what I would have expected from a Rubio 2016 presidency: tough on dictatorships, use of force in Iran to stop them from getting nuclear weapons.”
The Stakes for Cuba
As the pressure mounts on the Cuban government, the ramifications are becoming increasingly apparent. The US embargo has severely strained the island’s resources, leading to widespread fuel shortages and extended blackouts in Havana. Some analysts liken the recent indictment of former Cuban leader Raúl Castro to the case against Nicolás Maduro, which precipitated a dramatic US raid in Venezuela.

Even without direct military intervention, the existing sanctions could compel Cuba’s communist leadership to negotiate. However, concerns linger regarding the absence of a coherent strategy for what follows should the current regime falter. As Juan Sebastián González, the former senior director for the Western Hemisphere, noted, “I think the risk right now is not really that the pressure fails, it is that the pressure succeeds, and there’s nothing to catch the fall here. There’s no plan on what comes next.”
Why it Matters
Rubio’s intensified focus on Cuba represents not only a personal ambition but also a pivotal moment for US foreign policy in Latin America. As the administration grapples with criticisms and strategic dilemmas abroad, the evolving situation in Cuba could set a precedent for how the United States engages with authoritarian regimes in its sphere of influence. The stakes are high, as both the future of Cuba and the integrity of US foreign policy hang in the balance.
