Should the U.S. pursue military intervention in Cuba to force political change?
The U.S. Army Reserve has initiated readiness assessments for military police, medical, and support units in relation to potential operations involving Cuba. The move aligns with the administration's stated goal of achieving fundamental change in the Cuban government.
Why it matters
The assessment supports the administration's Donroe Doctrine, which seeks to pressure the Cuban government through sanctions and military readiness. President Trump has publicly signaled that he believes the current Cuban administration will fall.
The Army Reserve is evaluating force availability for specialized units, including an engineer battalion, a medical brigade, and a support battalion for transportation and maintenance. These units are being assessed for a potential deployment window of 90 to 120 days.

Political Context

The potential mobilization of Army Reserve units suggests a significant shift in U.S. foreign policy that could impact regional travel and economic ties with Cuba. Taxpayers should anticipate potential changes to defense spending and shifts in diplomatic regulations regarding the island.
