ABSTRACT
This part introduction presents an overview of the key concepts discussed in the subsequent chapters. One important fact is that liberal democracies do not make war on each other. Another important fact is that the more two nations are democratic, the less violence between them. Yet another is that the more democracy, the less collective domestic violence, such as riots, rebellions, guerrilla warfare, and the like. A fourth important fact is that the more democracy, the less democide. As more nations become democratic and these zones of peace are thus enlarged, the zone of violence and war should thereby decrease. If ever all nations were to become democratic people have the promise of eliminating war and sharply reducing the amount of political violence.
