[Gildor said,] "The Shire is no longer protection for you."
"I cannot imagine what information could be more terrifying than your hints and warnings," exclaimed Frodo. "I knew that danger lay ahead, of course; but I did not expect to meet it in our own Shire. Can't a hobbit walk from the Water to the River in peace?"
"But it is not your own Shire," said Gildor. Others dwelt here before Hobbits were; and others will dwell here again when hobbits are no more. The wide world is all about you; you can fence yourself in, but you cannot for ever fence it out."
I think in America we sometimes have the idea that all the trouble in the world, all the unsafe places are far away and no bother to us. We think we can fence ourselves in and avoid dealing with the barbarians in other parts of the world. But the world is always changing, and even today freedom wanes. Truly, freedom here is dependent on freedom "out there."
