Marco Rubio, the Secretary of State, emphasized the US's commitment to changing Cuba's communist regime following an indictment of former president Raúl Castro. He described Cuba as a 'failed state' amid its economic crisis and warned that the US would not be waiting for Cuba to change. The US military has increased its presence in the Caribbean, while Cuba has called for protests against the indictment. The situation is complicated by Cuba's reliance on Venezuela and the criticism from China and Russia regarding US actions.
