A growing rift is emerging within NATO as Poland refuses to deploy its Patriot air defence systems to the Middle East despite reported U.S. requests. Warsaw insists its systems are vital for national and eastern flank security. The development comes as the Iran war rapidly depletes Western missile stockpiles, with over 1,200 Patriot interceptors used in just 16 days. As pressure mounts, the U.S. is seeking support from allies, while South Korea steps in with cheaper alternatives like the Cheongung system. The shift signals a major transformation in global air defence dynamics, exposing cracks in alliances and reshaping the future of military supply chains.
