I encountered the following from David O. McKay where he explicitly (and correctly) states that true, lasting world peace will only come by accepting the person and teachings of the Lord Jesus Christ. As it was pretty spot-on, I am sharing it here:
Today, many nations have lost their independence; men, defeated, have been compelled to labor for their conquerors, property has been seized without recompense, and millions of people have surrendered all guarantees of personal liberty.
Force and compulsion will never establish the ideal society. This can come only by a transformation within the individual soul -- a life redeemed from sin and brought in harmony with the divine will. Instead of selfishness, men must be willing to dedicate their ability, their possessions, their lives, if necessary, their fortunes, and their sacred honor for the alleviation of the ills of mankind. Hate must be supplanted by sympathy and forbearance. Peace and true prosperity can come only by conforming our lives to the law of love, the law of the principles of the gospel of Jesus Christ. A mere appreciation of the social ethics of Jesus is not sufficient -- men's hearts must be changed!
In these days of uncertainty and unrest, liberty-loving people's greatest responsibility and paramount duty is to preserve and proclaim the freedom of the individual, his relationship to Deity, and the necessity of obedience to the principles of the gospel of Jesus Christ. Only thus will mankind find peace and happiness. (David O. McKay, Conference Report 1962, pp. 7-8)
