This complex process we call progressive ephemeralization. In 1970, the sum total of increases in overall technological know-how and their comprehensive integration took humanity across the epochal but invisible threshold into a state of technically realizable and economically feasible universal success for all humanity. This actual but invisible threshold crossing began in 1969 when humans' scientific knowledge and technological ingenuity, backed exclusively by adequate citizens' tax-raised government financing, learned how to do so much with so little as to be able to place humans on the Moon and return them safely to Earth. It could further be demonstrated that we can do this while simultaneously phasing out all further Earthians' use of fossil fuels and atomic energy. There is now plenty for all.
War is obsolete.
