It has been argued that World War II had to happen. According to this argument, by the late 1930s a variety of economic, social, and political factors had created worldwide tensions so high that only a major conflict could relieve them. Germany and other nations that felt "cheated" by the outcome of World War I decided it was time to take back what they believed was theirs - and then some.

Discover what circumstances led to the outbreak of World War II, how everyday people and their leaders reacted to it, and how its outcome affected the world for the rest of the twentieth century and beyond.
