Nothing can unite humans like a common enemy. Time and time again, circumstances have forced previously hostile forces to come together for the sake of the common good. That is, essentially, what this timeline is about. "At the end of humanity, when all seems dark and forboding, we, as humanity, must join forces to save ourselves and our species. The outcome of this battle determines whether there is a humanity for the next thousand years. Humanity expects every man and woman to do their duty. - President Dwight D. Eisenhower, July 14, 1957
