In D&C 38: 30 the Lord promises us that "if ye are prepared ye shall not fear." Without such a promise we might well fear the disasters of the world in which we live. Andrew F. Krepinevich has written about some of the awful possibilities in 7 Deadly Scenarios, which Bret Stephens reviews in "Farewell, Tranquil Mind" in a recent edition of The Wall Street Journal.
"Mr. Krepinevich's concern is with the worst that can plausibly happen to the U.S. . . . within the next decade. What's plausible?" He spins out possible scenarios involving nuclear bombs being detonated in U.S. cities, a global avian-flu pandemic that "sends a desperate human tide coming up from Mexico" and others.
The Lord has counseled us to prepare both spiritually and temporally. "Prepare ye, prepare ye, for that which is to come . . . ." (D&C 1: 12)
