Did Tolkien find the idea of war honourable?

TTT: Window On The West, Faramir speaking:

War must be, while we defend our lives against a destroyer who would devour all; but I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend; the city of the Men of Numenor; and I would have her loved for her memory, her ancientry, her beauty, and her present wisdom. Not feared, save as man may fear the dignity of a man, old and wise.

Tolkien's opening description of Faramir in Letters (Letter 66) :

A new character has come on the scene (I am sure I did not invent him, I did not even want him, though I like him, but there he came walking in the woods of Ithilien): Faramir, the brother of Boromir-- and he is holding up the 'catastrophe' by a lot of stuff about the history of Gondor and Rohan (with some very sound reflections no doubt on martial glory and true glory): but if he goes on much more a lot of him will have to be removed to the appendicies...

"Very sound reflections". I think TOlkien was stating that he agreed with Faramir's statement, quoted above.
