Leadership in this society here would naturally fall to the paranoids. . . . But you see, with paranoids establishing the ideology, the dominant emotional theme would be hate. Actually hate going in two directions; the leadership would hate everyone outside its enclave, and also would take for granted that everyone hated it in return. Therefore their entire so-called foreign policy would be to establish mechanisms by which this supposed hatred directed at them could be fought. And this would involve the entire society in an illusory struggle, a battle against foes that didn’t exist for a victory over nothing.
