Does Cuba even have the missiles and drones to do this? The Cuban Revolutionary Armed Forces are equipped with mostly outdated and cobbled together technology.

I couldn’t find any long range strike capability in this [list of equipment](Cuban Revolutionary Armed Forces). That doesn’t mean they don’t have any. A couple of containers filled with Shahed long range drones could be hiding in a warehouse. Serious ballistic missiles are less likely to exist. I couldn’t find any info on the Air Force owning cruise missiles for their jets.

Cuba could run a fierce defense and Guerilla war against an full invasion. They have the culture, experience, equipment, and organization for it. That is, if the will to fight is strong enough
