Danny and Derek speak with historian Andrew Preston about the origins and development of the American national security state as we know it. They discuss the original meaning of “national security” in the early days of the republic; the idea of free security; the New Deal and the relationship between social security and national security; World War II, the Cold War, and the expansion of the security state; liberalism and American empire; and what national security looks like moving forward.

Be sure to grab a copy of Andrew’s book on the subject, Total Defense: The New Deal and the Invention of National Security.
