Explanation:
World War II caused greater destruction than any other war in history. The war took the lives of about 17 million soldiers and an even greater number of civilians, who died as a result of bombings, starvation, and deliberate campaigns of mass murder. The war also ushered in the atomic age and was quickly followed by the collapse of the wartime alliance between the United States and the Soviet Union and the beginning of the Cold War.
World War I created the conditions that led to World War II. The peace settlement ending the war, which stripped the Central Powers of territory and arms and required them to pay reparations, left lasting bitterness in Germany, Austria, Bulgaria, Hungary, and Turkey. The peace treaty also disappointed two of the victors, Italy and Japan. In addition, the war severely disrupted Europe's economies and helped set the stage for the Great Depression of the 1930s.
