For six decades, Cuba was ruled by either Fidel Castro or his brother Raúl. But Fidel died in 2016, and Raúl gave up power two years later. In April 2018, Miguel Díaz-Canel became Cuba’s new president. Cuba remains a repressive Communist regime, but there’s some hope that the new president will begin to make Cuba more open and free. Díaz-Canel faces two major challenges: a struggling economy and an increasingly rocky relationship with the U.S., as President Trump has taken a more hardline approach to Cuba than President Obama, who had taken steps to normalize relations.
