The Americans celebrating their victory with loved ones also looked ominously toward a dangerous, complex, and potentially violent postwar world. Happiness, however, was also a fleeting emotion. Happiness was evident in the street parades, the family reunions, and the new births (“the baby boom”) that filled American society immediately after the war. For American citizens who saved and sacrificed in the 1930s and early 1940s, the next decade promised unprecedented security and abundance. American farmers also benefited from mass production and distribution, selling enough food at war’s end to feed populations around the globe. Above all, the United States had developed the capability to produce more military and civilian goods (aircraft, cars, radios, and guns, among many other items) than the rest of the world combined. The shocking atomic bombings of Hiroshima and Nagasaki proved this point.

Thanks to generous government investments and the immigration across the Atlantic of some of Europe’s best minds, American science and technology had advanced beyond all peers. American soldiers had decisively defeated the seemingly invincible German and Japanese militaries. The country that had suffered from dust bowls, economic depression, and a devastating attack on its Pacific naval fleet in the last decade-and-a-half emerged as the dominant global actor. The late summer of 1945 marked the height of American power.
