In this thesis, I argue that civil defense failed to take hold in the United States because it required local communities to take responsibility for protective measures. Fargo, North Dakota provides a case study for this analysis. The first section examines how Fargo adopted many practices from federal, state, and municipal civil defense organizations in the early 1950s, but struggled to implement them due to volunteer shortages. The second section explains how the hydrogen bomb forced officials to revise civil defense policies. It also details efforts by congressional and private bodies to increase federal responsibility for civil defense. The third section covers Fargo’s lack of response to the Berlin and Cuban Missile Crises, focusing on the unwillingness of Fargoans and their government to invest in civil defense. I conclude that today’s policymakers should recognize the limitations of making local communities responsible for policy implementation.
