From Vietnam to Afghanistan, why do powerful countries keep losing wars? In this episode, I speak with author and professor of strategic studies Phillips O'Brien, one of the world’s sharpest analysts of modern warfare and grand strategy. Right now, Russia is bogged down in Ukraine, and the US has just attacked Iran. My goal in this conversation is to understand why leaders and analysts repeatedly misjudge conflicts… initiating wars they can’t win or extract themselves from. We discuss what victory really means, how leaders manage perception and public consent, full-spectrum power, and the changing face of US dominance.
