States are communities whose policies are shaped by culture, worldview, and emotion. A classroom analogy explains how a group's shared mood can influence behavior even when its members remain individuals.

Weimar Germany still had other possible futures, but accumulated grievance helped make it fertile ground for Nazism. With the United States outside the League of Nations, Britain, France, Italy, and Japan needed enough confidence and strength to support the interwar security order rather than feel bound or diminished by it.
