The US Army Reserve headquarters has circulated an internal memo requesting military units for potential deployment to Cuba within the next four months, according to a leaked document obtained by CBS News. President Trump stated at the United Nations that Cuba's communist government "will fall" and that freedom is coming to the island, whilst his Secretary of State is reportedly conducting negotiations with Havana. This military planning forms part of what officials have termed the "Donroe Doctrine", an assertive strategy to remove adversaries from America's sphere of influence in Latin America and the Caribbean.

The memo requests six types of military units, including forward surgical teams, combat engineers, military police, medical brigades, logistics units, and an expeditionary sustainment command, with a potential deployment window of 90 to 120 days. No formal deployment orders have been issued, and the memo does not specify troop numbers or operational details. This planning follows the January capture of Venezuelan dictator Nicolás Maduro by US special forces, and comes as the Trump administration has imposed additional sanctions on Cuban military-linked entities. Cuban President Miguel Díaz-Canel has pledged to defend against any American military action, denouncing what he characterises as US aggression and economic warfare.
