US-Israel offensive in Iran reshapes alliances and public opinion worldwide

A joint U.S.-Israeli offensive against Iran is triggering cascading geopolitical and domestic political fallout. Europe is split over how far to back the war, China faces an economic and diplomatic bind, Turkey weighs its own security interests, and the conflict diverts critical air-defense resources with implications for Russia and Ukraine. At the same time, U.S. politics are roiled as Americans—including Trump’s own voters—are deeply divided over the strikes, while analysts warn that escalation could paradoxically strengthen Iran even as international actors demand it comply with its obligations.
