Jonah Goldberg, explaining some of the material in Liberal Fascism --
nationalism and socialism are almost always synonymous terms. Hugo Chavez is a nationalist who is nationalizing his country's industry. Or you could say he's a socialist who is socializing his country's industry. The two words are interchangeable: socialized medicine is nationalized medicine.
So socializing = nationalizing. National Socialism. Nazi. Geddit?
More seriously, Goldberg still won't explain why he has classified Mussolini as being on the left when Mussolini did such a good job of preserving Italy's institutions -- the monarchy and the Church -- under his rule.
