I feel impelled to speak today in a language that in a sense is new, one which I, who have spent so much of my life in the military prof ession, would have preferred never to use. That new language is the language of atomic warfare. The atomic age has moved forward at such a pace that every citizen of the world should have some comprehens ion at least in comparative terms, of the extent of this deve lopment, of the utmost signif icance to everyone of us. Clearly, if the peoples of the world are to conduct an intelligent search for peace, they must be armed with the signif icant facts of today s existence My recital of atomic danger and power is necessarily stated in Un ited States terms, for these are the only incontrovertible facts that I know. I need hardly point out to this assembly however, that this subject is global, not merely natio nal in character.
