NATO says prepared to defend allies amid reports Iran considered strikes on US targets in Europe

NATO has declared it is fully prepared to defend its allies following reports that Iran is considering retaliatory strikes against U.S. military targets in southeastern Europe, including installations in Bulgaria and Cyprus. The threat emerges after a June 2026 U.S.-Iran memorandum of understanding expired on August 17, 2026, leaving diplomatic talks stalled. While Bulgaria has increased security at its Bezmer Air Base, Iran warns that any nation assisting U.S. military actions will face consequences.
