US Secretary of State Marco Rubio #sanctions Raul Castro's grandson , Fidel Ernesto Castro Calis, reiterating the goal of "liberating Cuba." The ethnic Cuban politician is a key lobbyist for aggressive actions against Havana, including potential invasion and regime change. Rubio's influence grew after Venezuela's capitulation. He previously supported an airborne operation against #Iran to test methods for a future amphibious landing in #Cuba, but failed as Tehran refused to surrender.
