The first dramatic step to explain our position could well bee announcement by you before the UN, or other appropriate forum, pending a safeguarded nuclear weapon ban plus inspection and disarmament, the U.S. will {1) produce and use only clean weapons ies soon as testing develops that capability) and use them only in self defense; (2) eliminate all or most of the danger fram nuclear tes by testing under ground or by testing above ground in clean versi t, only; and (3) share the principles of clean weapons with the Soviet Union in order that it also may protect the rest af mankind in the event of nuclear war. Although the offer to share the principles of clean weapons may be opposed on political and technical grounds and cannot be impl nted with respect to wholly clean weapons until we know how to make them, it is most important psychologically anc should not be discarded without convincing evidence that the disclosures which might be involved would be contrary to national interest. Fallure to tie this offer to other proposals might lead to a demand by the USSR or a neutral country that we show good faith by sharing our knowledge.
