Chapter 7: Crash moves through the giddy optimism of the Roaring Twenties and into the greatest calamities the modern world had ever known. We begin with jazz, speakeasies, and the glittering world of The Great Gatsby. Americans believed prosperity was the new normal and that technology would lead us only upward. Then the good times crashed on Black Tuesday in 1929, bringing that glittering decade to a sudden end. The Great Depression brought breadlines and dust storms to the country, replacing confidence with desperation. Franklin Roosevelt stepped in with bold experimentation — the New Deal — though not without critics who suspected government power was creeping too far into private life. Meanwhile, a dark storm was gathering abroad. Totalitarian regimes — Stalin’s Soviet Union and, most chillingly, Hitler’s Germany — rose by exploiting fear and national humiliation. Pearl Harbor thrust the nation into the conflict, shattering any illusions of isolation. The war was savage — from the beaches of Normandy to the jungles of the Pacific — but Americans pressed forward in every direction. And then, as if racing toward some terrible crescendo, science delivered a power so vast it seemed ripped from myth: the atomic bomb. When the blasts lit the skies over Hiroshima and Nagasaki in 1945, they forced Japan’s surrender and sealed the defeat of the Axis powers. The chapter ends not with celebration, but with a sober recognition that humanity had crossed a threshold. We had survived a global depression and a world war, yet we stood staring into a new and uncertain age where the ability to annihilate ourselves might now be our most defining achievement.
