It was a different world
Just finished Herman Wouk's Winds of War and War and Remembrance. A monumental effort, but well worth the investment of time and attention.
You think you learned the history in school, but if your education was like mine, you only skimmed the surface. I read these books to gain a deeper grasp of my father's generation, of the sacrifices they made, and of the events that shaped their world view. I came away with so much more than that. My faith in humanity was restored.
