The Trump administration is actively considering a naval blockade of Cuba, according to senior US officials, as the island faces complete economic collapse following the severing of Venezuelan oil supplies. The potential intervention would represent the most aggressive US action against Cuba since the 1962 missile crisis, coming just weeks after American forces captured Venezuelan President Nicolás Maduro and dismantled the Caracas-Havana economic axis that had sustained the island for over two decades.
The move follows President Trump's stark assessment Tuesday that "Cuba will be failing pretty soon," citing Venezuela's inability to send "oil or money to Cuba" after Maduro's removal. What makes the situation critical is Mexico's rapid retreat from its role as Cuba's emergency energy supplier—a development that exposes Havana's complete vulnerability to US economic warfare and demonstrates the administration's capacity to weaponize regional trade dependencies with devastating precision.
Mexico retreats under trade pressure
Mexico had emerged as Cuba's primary oil supplier in 2025, providing 44% of the island's petroleum imports as Venezuelan shipments became increasingly erratic before Maduro's capture. But that lifeline is now being systematically severed under intense US pressure ahead of the upcoming USMCA trade agreement review.
Mexican President Claudia Sheinbaum confirmed Tuesday that her government canceled at least one scheduled oil shipment to Cuba, though she attempted to frame the decision as an exercise of "sovereign energy policy" rather than capitulation to Washington. The timing, however, reveals the true calculus: with the USMCA review approaching and the Trump administration explicitly linking trade access to cooperation on its Cuba strategy, Mexico cannot afford to maintain energy transfers to Havana.
The cancellation leaves Cuba without a viable alternative energy source. Venezuela's supply has ceased entirely following Maduro's capture by US forces, while Russia and other potential suppliers lack both the capacity and willingness to challenge direct US naval interdiction in the Caribbean basin.

Regional order reconfigured through energy control
The Trump administration's Cuba strategy demonstrates how the post-Maduro Caribbean is being restructured around absolute US dominance of energy flows. With Venezuela's supply infrastructure under American control following the recent military strikes and Mexico now compliant under trade coercion, Washington has achieved what decades of sanctions alone could not: the complete severing of Cuba's external economic lifelines. Whether the naval blockade is formally implemented or remains an implicit threat, the island's trajectory toward systemic failure appears locked in, absent a dramatic shift in either US policy or Cuba's internal governance structure.
