Turkey believes it is too big to fail, that Washington needs Ankara more than Ankara needs Washington. Across multiple administrations, U.S. presidents have largely agreed. That belief has bought Turkey remarkable latitude even as, for over two decades under the leadership of Recep Tayyip Erdoğan, it has engaged in behavior that often runs counter to U.S. interests: purchasing Russian air defenses in defiance of U.S. law; blocking NATO consensus on enlargement and cooperation; detaining American citizens; funding and sheltering U.S.-designated terrorist organizations; and becoming one of the leading global hubs for Russian sanctions evasion.
This page brings together JINSA’s research on Turkish behavior, updated as new evidence emerges: a JINSA Insight documenting the hundreds of Turkey-based individuals and entities sanctioned by the United States since 2008; a detailed spreadsheet of every sanctioned entity with program, nationality, and sourcing; and a chronological timeline of Turkish actions contrary to American and allied interests since 2002, organized by category and led by the entries that most directly bear on Turkey’s reliability, or lack thereof, as a U.S. ally. Together they offer policymakers a factual record that outlasts the diplomatic language of any particular moment.
