Alexander Wendt, political scientist at Ohio State University, discusses his forthcoming book The Last Humans: UFOs & National Security, on the political and national security consequences of discovering that Unidentified Aerial Phenomena (UAPs) are piloted by intelligent extra-terrestrial life. He argues that the ontological shock from this discovery risks triggering a civilizational “auto-immune reaction” of widespread disorder that could undermine the international state system and suggests possible policies and pathways to responsibly prepare for this scenario.

Barry Posen, professor of political science at MIT, argues that Russia’s invasion of Ukraine in 2022 qualifies as a preventive war and was motivated in part to thwart U.S.-led efforts to expand NATO in Europe. He responds to detractors from this view and also discusses the partial political responsibility of U.S. leaders, the difference between explaining the war and justifying it, the lack of strategic empathy in U.S. foreign policy, how best to negotiate the end of the war, and whether the U.S. is making a similar mistake in incentivizing preventive war logic in Beijing with respect to Taiwan.
