Nov 19, 2024
Peter Rohde, historian and former Pentagon national security policy adviser, traces how the label "national security" was broadened and then narrowed over time. He explores FDR’s push to include economic and social well being, the political power of the security frame, debates over public health, fentanyl, climate change, and where lines should be drawn.

Episode notes
FDR's Broad Definition Of National Security
- Peter Rohde argues national security should be defined broadly to include citizens' welfare, not just military defense.
- He traces this broader view to FDR, who linked economic and social security to national survival during the Great Depression.
FDR Used Fireside Chats To Frame Welfare As Security
- Peter Rohde recounts FDR's use of fireside chats to sell New Deal programs as security measures to the American public.
- Roosevelt used radio sparingly and deliberately so each address functioned as a persuasive mass-communication event.
Postwar Institutions Narrowed National Security To Defense
- Rohde shows postwar actors reshaped the meaning of national security by privileging defense agencies over domestic welfare.
- The 1947 National Security Act institutionalized that shift by creating defense and intelligence structures while omitting domestic security.
