# UFOs, Aliens, & National Security 

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.
