D&C 63

Conspiracy Rising Ref. 29

33 I have sworn in my wrath, and decreed wars upon the face of the earth, and the wicked shall slay the wicked, and fear shall come upon every man;
34 And the saints also shall hardly escape; nevertheless, I, the Lord, am with them, and will come down in heaven from the presence of my Father and consume the wicked with unquenchable fire.

This passage shows that the wars of the last days are decreed by God to allow the wicked to slay the wicked. The saints will be accosted with fear, and possibly war.
