United States officials, led by Secretary of State Marco Rubio, are intensifying demands for a change in Cuba's leadership, citing the island nation's dysfunctional economy and political system. This escalating pressure from the Trump administration includes a de facto fuel embargo and threats of further sanctions, exacerbating Cuba's severe economic crisis and humanitarian fallout. Rubio dismissed recent Cuban reforms as inadequate, while President Trump hinted at imminent new actions, amid reports that Washington is seeking President Miguel Diaz-Canel's resignation. These heightened diplomatic efforts coincide with dire conditions on the island, underscored by a recent national power outage and the enduring decades-long US trade embargo.
