Those who did survive could eventually flourish on an Earth free from the problems of pollution, overpopulation, and civil unrest. Yes, unattended nuclear technologies would eventually melt down, and satellites would eventually plummet back to earth, so the survival game is not over yet. But when all is said and done, the survivors would inherit a world of abundance that takes window shopping to lofty new extremes. Those saved, chosen by a computer lottery at a ratio of 10 women to 1 man, would be charged with little else than breeding prestigiously. According to Strangelove, the Gross National Product could be up to normal within 20 years of returning to the surface.
Religion is another valuable source of post-apocalyptic utopianism.
Religious views frequently suggest that those who survive The Apocalypse would live to see a paradise born on Earth. Central to their beliefs is that the end of 6,000 years of human existence will bring Christ's Second Coming, the restoration of Palestine, and the announcement of Armageddon. Only 144,000 Jehovah's Witness Saints will survive this apocalypse. The Kingdom of God will reside here on Earth for the following 1,000 years, until God restores dominion of the world back to humanity, and the whole cycle is free to start all over again. The Jehovah's Witnesses are by no means alone in their post-apocalyptic views.
