The more people are free, the greater their human development and national wealth. In short, freedom is the way to economic and social human security. - Rudolph Rummel

In total, communist (Marxist-Leninist) regimes murdered nearly 148 million people from 1917 to 1987. For a perspective on this incredible toll, note that all domestic and foreign wars during the twentieth century killed in combat around 41 million.

Libertarian states have no violence between themselves. The more libertarian two states, the less their mutual violence. The more libertarian a state, the less its foreign violence.

Increasing freedom in the world decreases the death toll of its wars. Surely, whatever reduces and then finally ends the scourge of war in our history, without causing a greater evil, must be the greatest moral good. And this is freedom.
