Mormon indicated that the Nephites would have been spared bloodshed had they not launched an offensive war against the Lamanites, "for were it not for that, the Lamanites could have had no power over them." (Mormon 4:5.)
Then he provided this commentary: "But, behold, the judgments of God will overtake the wicked; and it is by the wicked that the wicked are punished; for it is the wicked that stir up the hearts of the children of men unto bloodshed." (Mormon 4:6.)This seems to suggest that war and its attendant suffering come as a natural result of wickedness, not because they are the will of God.
"Of one thing I am sure," Brigham Young said, "God never institutes war; God is not the author of confusion or of war; they are the results of the acts of the children of men. Confusion and war necessarily come as the results of the foolish acts and policy of men; but they do not come because God desires they should come. If the people, generally, would turn to the Lord, there would never be any war. Let men turn from their iniquities and sins, and instead of being covetous and wicked, turn to God and seek to promote peace and happiness throughout the land, and wars would cease. We expect to see the day when swords shall be turned into ploughshares, spears into pruning hooks, and when men shall learn war no more. This is what we want. We are for peace, plenty and happiness to all the human family." (Discourses of Brigham Young, pp. 366-367.)
With a tone of urgency, President Ezra Taft Benson has warned of wars and other calamaties that will result in the current age unless the earth's inhabitants repent. Addressing leaders and citizens of nations, he has written:
"Wars, devastation, and untold suffering will be your lot except you turn unto the Lord in humble repentance. Destruction even more terrible and far-reaching than attended the last great war will come with certainty unless rulers and people alike repent and cease their evil and godless ways." (The Teachings of Ezra Taft Benson, p. 73.)
