“Remember the lessons of history. Remember how often whole peoples have allowed themselves to be persuaded to go to war by ‘wise’ men—and then been utterly destroyed by the very enemy they agreed to attack! Remember how many statesmen have helped raise new leadership to power—and then been overthrown by their own protégés! Remember how often leaders have chosen to treat their friends like slaves—and then perished in the revolutions caused by their idiotic methods! How many powerful men have craved to dominate the world—and by overreaching have lost everything they once possessed!”
