US military contingency planning for potential action against Cuba has advanced in recent weeks, with the Army Reserve assessing logistics, medical, engineering, and military police support units for US Southern Command that could be needed within 90-120 days, according to internal documents reviewed by CBS News. No deployment orders have been issued, and earlier reconnaissance and readiness measures remain in place amid administration concerns over Cuba's ties to Russia, China, and Iran. President Trump has repeatedly stated that military force is unlikely, emphasizing expectations of a bilateral deal while the administration tightens sanctions, travel restrictions, and an oil embargo. Cuban officials have acknowledged communication channels but deny formal negotiations, rejected demands for political change, and reported heightened defensive preparations. These developments frame trader assessments around the balance between sustained economic pressure and the absence of confirmed escalation triggers.
