FDD Action’s Connor Pfeiffer argues in The Wall Street Journal that the Cuban regime poses far more than a symbolic threat to the United States. While some analysts focus on Cuba’s role as a longstanding anti-American symbol, Pfeiffer contends that Havana’s intelligence services have actively penetrated the U.S. government at the highest levels — sharing sensitive information with China, Russia, and Iran. He warns that Cuban support for international terrorism compounds the danger, making the island’s regime a direct homeland security concern. As the Trump administration weighs its approach to Cuba, Pfeiffer makes the case that the national security threat cannot be overlooked.
