A couple more really good Book of Mormon articles:
Why do we read so much about wars in the Book of Mormon? Why did the prophets record so much about their wars and contentions? Why do we live in an age of wars and what are we to do? Elder Marion G. Romney made this observation: "Latter-day Saints know that this earth will never again, during its telestial existence, be free from civil disturbance and war." That being the case, the Book of Mormon can help us to face the problems arising from such a situation.
