President Donald Trump has declared a national emergency over Cuba, citing the island nation's alignment with hostile foreign powers and support for terrorist groups. The executive order enables the United States to impose tariffs on countries that supply oil to Cuba, aiming to increase pressure on the communist regime. The administration accuses Cuba of deepening intelligence and defense cooperation with Russia and China, hosting transnational terrorist groups, and committing human rights abuses against its own citizens. The move marks a significant escalation in United States policy toward Cuba, reinforcing Trump's commitment to confronting regimes seen as threats to American interests.
