The 1930s and 1940s were trying times. A global economic crisis gave way to a global war that became the deadliest and most destructive in human history. Perhaps eighty million individuals lost their lives during World War II. The war saw industrialized genocide and nearly threatened the eradication of an entire people. It also unleashed the most fearsome technology ever used in war. And when it ended, the United States found itself alone as the world’s greatest superpower. Armed with the world’s greatest economy, it looked forward to the fruits of a prosperous consumers’ economy. But the war raised as many questions as it would settle and unleashed new social forces at home and abroad that confronted generations of Americans to come.
