The universe grows smaller every day. There must be security for all, or no one is secure. It is no concern of ours how you run your own planet. But if you threaten to extend your violence, this Earth of yours will be reduced to a burned-out cinder. Your choice is simple. Join us and live in peace, or pursue your present course and face obliteration. We shall be waiting for your answer. The decision rests with you.
