Pentagon Chief Warns Cuba Against Acquiring Weapons During Guantánamo Visit

The US Secretary of Defence, Pete Hegseth, made an unannounced visit to the Guantánamo Bay naval base on Wednesday and delivered his most explicit warning yet to the government in Havana: any attempt to acquire weapons capable of threatening the base or US territory would be “imprudent” and would provoke a confrontation Cuba “could not withstand.” Dressed in military fatigues before an audience of troops, Hegseth declared that the future of the island lay “in the hands of President Donald Trump” and the Cuban leadership, but that the Pentagon – which he pointedly referred to as the “War Department” – stood ready for “any possible contingency.”

The visit, announced only the night before, was part of a wider campaign of maximum pressure on the Communist-run island. Washington has tightened sanctions on senior officials and imposed an asphyxiating oil blockade that, according to regional reports, has triggered daily blackouts of up to twenty hours. Viewed from Latin American capitals, the visit is one more step in a decades-long US policy of coercion that continues to treat the detention camp and naval station as a lever against Havana.

Hegseth’s specific arms warning appeared to be prompted by intelligence reports, cited last month by Axios and carried in Mexican financial daily El Financiero, that Cuba had procured more than 300 military drones and had discussed plans to strike Guantánamo or even Key West, just 145 kilometres away. While the Pentagon did not publicly confirm those claims, Hegseth told the troops that any such move would open the door to a conflict Cuba did not want and could not sustain. The phrasing, echoed in Russian state media without editorial comment, underscored the stark asymmetry of power.

European diplomatic circles noted Hegseth’s deliberate use of the archaic term “Department of War” – the Pentagon’s official name until 1947 – as a rhetorical signal that the administration is prepared to treat Cuba not as a diplomatic problem but as a potential theatre of military operations. This language, largely absent in European coverage before the visit, jars with the more cautious formulations typically employed by allied governments. Meanwhile, Latin American media uniformly described the trip as a “show of force” and a message that Washington will not tolerate any military modernisation on the island that could challenge its strategic assets.

Barring a dramatic change in either Washington or Havana, the stand-off is likely to endure. The Guantánamo base remains a potent symbol of unresolved Cold War frictions, and the Trump administration’s willingness to brandish military readiness while tightening economic screws suggests that diplomatic off-ramps are few. For now, Hegseth’s warning serves less as an immediate prelude to conflict than as a calculated reinforcement of a deterrent posture that leaves Cuba with little room to manoeuvre.
