A third great calamity engulfed humanity between 1931 and 1945. The Second World War grew from long-germinating seeds: the Spanish Civil War, the Great Depression, the inequitable Versailles Treaty, the unprecedented scale and carnage of the Great War, the paternalistic and racist colonialism of the European powers (and the seething anger it engendered in colonials and competitors), rapacious American capitalism (also racist), and the dizzying pace of technological change that destabilized traditional patterns of life across the globe.
The direct causes of the war are obvious?the rise of fascism in Italy, National Socialism in Germany and jingoistic militarism in Japan. All three members of the Tripartite Pact (the Axis) had enormous popular support at home. The aggressive policies of the Axis leaders provoked the war. In Asia it began with the Japanese invasion of Manchuria in 1931, in Africa with the Italian invasion of Ethiopia in 1935, in Europe with the German invasion of Poland in 1939, and in the United States with the Japanese attack on Pearl Harbor in December 1941 (the U.S. Navy had engaged German submarines in the Atlantic in April and the encounters escalated throughout the year). By 1942, most nations worldwide had declared for either the Axis or the Allies?few countries were neutral.
With a scale and scope previously unseen and unimagined in human history, the conflagration of World War II irrevocably changed the world. By summer?s end in 1945, the world had entered the nuclear age and uncharted territory. A seemingly endless Cold War with its MAD threat (Mutually Assured Destruction) and limited hot wars (Korea and Vietnam) resulted.
Ordinary people the world over keenly felt the shock of total war. Killed, wounded in body and mind, tortured and abused, made homeless, isolated, despairing and afraid, the peoples of the world suffered as never before. As a result of the war, every single person was potentially at risk?war knew no limits.
And yet, within a generation, the world seemed remarkably different. Despite the Cold War, the United States had grown far more prosperous and the material standard of living reached unprecedented heights. A ravaged Europe recovered?with help (the Marshall Plan). Japan rose from the ashes to become the world?s third greatest economy. Throughout Africa and Asia new nations arose from the wreckage of colonialism. Why?
