Since advancing freedom of the press furthers democracy, spreading freedom of the press promotes world peace. And the reverse logic is also true. Wit… - Rudolph Rummel

The more constrained the power of governments, the more it is diffused, checked and balanced, the less it will aggress on others and commit democide. At the extremes of Power, totalitarian communist governments slaughter their people by the tens of millions, while many democracies can barely bring themselves to execute even serial murderers.

Communists, when in control of a nation, have murdered more than 3.6 times the number of people killed in combat in all wars, including the two world wars.

Libertarian states are by theory not only less violence prone, but when foreign relations includes the perception of other libertarian states, this inhibition becomes a mutual barrier to violence. Their mutual domestic diversity and pluralism, their free and competitive press, their people-to-people and elite-to-elite bonds and relationships, and their mutual identification and sympathy will foreclose on any expectation or occurrence of war between them; violence may occur only in the most extraordinary and unusual circumstances, or at the margins of what it means to be libertarian.
