US military contingency planning for potential action against Cuba has advanced in recent months amid the Trump administration’s pressure campaign, with September 2026 reports detailing Army Reserve assessments of support units for U.S. Southern Command and prior reconnaissance and readiness measures around the island. President Trump has repeatedly stated that a deal is likely and military force will not be needed, while tightening sanctions, restricting travel and banking access, and criticizing Cuba’s ties to Russia, China, and Iran. Havana maintains open communication channels but has rejected negotiations on political change and stepped up defensive preparations. These developments, set against Cuba’s economic strains from the embargo and internal challenges, shape trader assessments of escalation risks through late 2026 and early 2027.
