Total war, total reckoning.
From the rise of fascism through the Holocaust, the Pacific theater, and the nuclear endgame. The war that made the U.S. and USSR the only powers left standing.
World War II (1939–1945) was the deadliest conflict in human history. Roughly 60 million people died — about 3% of the world’s 1940 population. The war began with Germany’s invasion of Poland, expanded across Europe, North Africa, the Pacific, and Asia, and ended with the atomic bombings of Hiroshima and Nagasaki. The Holocaust killed six million Jews and millions of Roma, disabled people, Soviet POWs, and others. The war ended European empire — within thirty years, almost every colony had become independent — and produced the United Nations, the postwar human-rights regime, and the Cold War that would structure global politics for the next forty-five years.
