Sometimes it has seemed to me that man's main accomplishment has been to tear down, rob pollute, kill. First, his earth, Then his fellow-men. In recent years has come our final, triumphal achievement: a nuclear contraption and a guided missile to carry it, works of such incredible complexity that only our handful of geniuses could create them, works that can blow up our planet in a jiffy, snuffing out life for good. Can, and probably will, given the folly of those who rule us and who have the power to decide.
