From the book "Lord of the Rings." I saw this pointed out on the Corner, and thought it was pretty good. The Mouth of Sauron is presenting surrender terms to the seemingly defeated forces of the West:

"Name the terms," said Gandalf steadily, but those nearby saw the anguish in his face, and now he seemed an old and wizened man, crushed, defeated at the last. They did not doubt that he would accept.

"These are the terms,: said the Messenger, and smiled as he eyed them one by one. "The rabble of Gondor and its deluded allies shall withdraw at once beyond the Anduin, first taking oaths never again to assail Sauron the Great in arms, open or secret. All lands east of the Anduin shall be Sauron's for ever, solely. West of the Anduin as far as the Misty Mountains and the Gap of Rohan shall be tributary to Mordor, and men there shall bear no weapons, but shall have leave to govern their own affairs. But they shall help to rebuild Isengard which they have wantonly destroyed, and that shall be Sauron's, and there his lieutenant shall dwell: not Saruman, but one more worthy of trust."

Looking in the Messenger's eyes they read his thought. He was to be that lieutenant, and gather all that remained of the West under his sway; he would be their tyrant and they his slaves.

I just finished reading the Trilogy again, and much is made throughout the story of the fact that those who dwell in peace and prosperity, the leading example being the hobbits of the Shire, do so only because armed and dangerous allies spent much time defending their outer borders. Aragorn (Strider) spent many years doing just this.
