This is the fourth episode in a 5-part series marking the 80th anniversary of the end of the Second World War in August 1945.

Before 1947, the United States did not have peacetime intelligence-gathering agencies such as the CIA. Foreign policy was formulated on an informal basis. Even during the Second World War, interservice cooperation was voluntary in the U.S. military. The Army and Navy had to compete for resources in the absence of a unified command structure. All this changed in 1947 with the passage of the National Security Act by large bipartisan majorities in the House and Senate. Its enduring importance cannot be overstated. In this episode, historian Daniel Bessner of the American Prestige podcast, an expert on U.S. foreign policy, delves into the origins of this permanent, expensive, and often dangerous structure.
