Hans-Hermann Hoppe discusses why internally liberal states tend to be Imperialist powers and how the spirit of Democracy has contributed to the de-civilization in the conduct of war.
More specifically Hoppe explains the rise of the United States to the rank of the world’s foremost Imperial power, as a consequence of the transformation, from the beginnings of an Aristocratic Republic to a mass Democracy, and the role of the United States as an increasingly arrogant war monger. What stands in the way of peace and civilization is above all the state and democracy.
