A terror state is a state in which citizens are too afraid to speak their own mind because of governmental reaction.

Features of terror states

Terror states rely on heavy use of propaganda, secret police and general governmental monitoring of everything you do, say, think and feel. Terror states are typically Totalitarian dictatorships.

Examples of terror states

Nazi Germany
Soviet Union
Fascist Italy

While Western democracies may use propaganda and keep governmental checks on citizens, they should NOT be compred to REAL terror states of the past and present, as this would be a giant middle finger to people who actually live in fear.
