Nato split over US access to European bases in Iran war

NATO faces deep divisions in April 2026 over potential U.S. military use of European bases for operations against Iran, exposing transatlantic rifts amid escalating Middle East tensions. Key members like Germany and France resist granting Washington access to critical airfields and ports, citing legal concerns and fear of regional destabilization without UN approval. The U.S. argues prepositioned assets in Europe are vital for rapid response, pressing allies to honor Article 5 collective defense principles despite the offensive nature of potential strikes. Smaller Eastern European nations, including Poland and Romania, reportedly support U.S. requests, reflecting divergent threat perceptions and reliance on American security guarantees. The stalemate risks undermining NATO unity as Iran’s nuclear advances and proxy attacks in the Gulf force allies to weigh strategic alliances against domestic political pressures and international law.
