Discussion: a. Genersl, ‘tomic weapons tests comiucted since sorld isr II by the United States, the Soviet Unien, and Great Britian asve resulted in contimied and ever increasing worldewide opposition to nuclear weapons testing. ‘This opposition has been principally because of the fallout (local and worldevide) associcted with weapons testing and the Leck of definitive knowledea as to its immedicte ami ultinate effects on the public haclth. The President has established ag national policy, < “nited Stcteg mor’ torium on atonic testinr, The oresent intern:tional nesotiations it “eneva, with reccrd to nuclear weapons testing, seck a mutually satisfcetory means of test detection and control, It has becove inereasingly anvarent, because of ner.tive world opindon, thrt we will mest likely never crain be permitted te conduct muclesr weanons testins of the actgnitudes .nd by the methods of the past.
