[Nimiriel]

I think Tolkien is (was) clearly trying to get a lot of messages through to his readers, among them the importance of not giving in to the desire for power (or wealth). What he say in the foreword is that the story itself is not to be seen as a picturing of the WW2 or anything like that. The story is a story in itself, but it still contains lots of messages and viewpoints on the world today, society and industry.
