hope this helps you

World War II was a terrible event that will be remembered as one of the darkest chapters in human history. With estimates of the dead ranging from 60 to 80 million, it is unthinkable to imagine that this event was allowed to fester and erupt as it did. Many in the United States simply figured the problems of Europe would be contained to that continent. However, a new enemy brought the war to our shores.
When the war began, the United States had entered a period of isolationism. Americans viewed the conflict as Europe’s problem and wished to keep it that way. However, as the situation in Europe grew increasingly dire, the United States began to slowly edge toward war. The breaking point, of course, was the sudden attack by the Japanese at Pearl Harbor. However, in retrospect, the attack may not have been such a sudden and unforeseen event. Tensions between the United States and Japan had been consistently escalating for several years before the attack.
