I am sure we covered this. We are told not to dwell on passages such as these, but work hard to become servants of humanity;
"The general messages of the Guardian to the world-wide Bahá'í community make clear reference in several places to a "retributive calamity" which will purify the human race and knit its components into a unified whole. One of the most detailed passages from the writings of the Guardian is the following:
"The violent derangement of the world's equilibrium; the trembling that will seize the limbs of mankind; the radical transformation of human society; the rolling up of the present-day Order; the fundamental changes affecting the structure of government; the weakening of the pillars of religion; the rise of dictatorships; the spread of tyranny; the fall of monarchies; the decline of ecclesiastical institutions; the increase of anarchy and chaos; the extension and consolidation of the Movement of the Left; the fanning into flame of the smouldering fire of racial strife; the development of infernal engines of war; the burning of cities; the contamination of the atmosphere of the earth — these stand out as the signs and portents that must either herald or accompany the retributive calamity which, as decreed by Him Who is the Judge and Redeemer of mankind, must, sooner or later, afflict a society which, for the most part, and for over a century, has turned a deaf ear to the Voice of God's Messenger in this day — a calamity which must purge the human race of the dross of its age-long corruptions, and weld its component parts into a firmly-knit world-embracing Fellowship..." (Taken from "Messages to the Bahá'í World 1950-1957" by Shoghi Effendi, page 103)
"He has been told that some of the friends are disturbed over reports brought back by the pilgrims concerning the dangers facing America in the future whenever another world conflagration breaks out....He does not feel that the Bahá'ís should waste time dwelling on the dark side of things. Any intelligent person can understand from the experiences of the last world war, and keeping abreast of what modern science has developed in the way of weapons for any future war, that big cities all over the world are going to be in tremendous danger. This is what the Guardian has said to the pilgrims..."
