Six months into a catastrophic war in Iran — and with no end in sight for the war in Ukraine — the world is embroiled in conflicts with no apparent exit plan. In this interview, political scientist and Eurasia Group founder Ian Bremmer breaks down what these wars are costing people around the world — and which one he's more worried might spiral out of control. (This interview, hosted by TED's Helen Walters, was recorded on July 28, 2026.)
