Why? Sauron was defeated once before when he had the Ring? Why couldn't he have been defeated again with the Ring? I understand it would have been a lot more painful and caused a lot more destruction, but couldn't it have been done? After all Narsil was reforged and there was soon to be a king in Gondor again.
Oh it makes me tired just thinkin about it! It is all so scary! - Can't we just go home to the Shire and forget the whole thing?
The first part of TTT really drives me nuts. Much as I love the rest of the company, I worry so about Frodo and Sam, and we go so long without news!
