We must never forget that the political character of a state, whether it is democratic, theocratic, fascist, or communist, says nothing about the foreign policy it will pursue. A democracy can be and often is relentlessly aggressive, while a fascist dictatorship could just as readily be pacific and isolationist. Indeed, a democratic nation with a Messiah complex is far more dangerous to the world and to its own people than a relatively authoritarian state that just wants to reign over its little corner of the globe. A danger to the world because the special arrogance that infuses would-be messiahs allows them to commit the greatest crimes for the noblest of reasons. A danger to their own people because the very act of aggression and empire-building destroys the liberal character of democratic states, eating away their substance from within.
Thanx to RAW Illumination.
