How did America become the world’s predominant power? Historian Stephen Wertheim joins the Prospect podcast this week to discuss the short history of America as the world’s policeman, which he outlines in his new book, Tomorrow the World. He also talks about what might happen next—and what a foreign policy under Joe Biden might look like. Stephen is Deputy Director of Research and Policy at the Quincy Institute for Responsible Statecraft, and is one of Prospect’s Top 50 Thinkers for 2020. Tomorrow the World is published by Harvard University Press. Hosted on Acast. See acast.com/privacy for more information.
