nuclear weapons is also in effect. Now it is up to the other nuclear Powers to act. The soviet Union is flexible about the ways in which this should be done; it could be either through unilateral declarations or a single international legal instrument. What is important is to resolve this issue in substance, and the sooner this is done the better.

The implementation of the entire complex of material and contractual guarantees against the threat of nuclear war, that we have mentioned, is of primary and increasing importance. But we are ready to consider other, what could be called collateral measures, such as preventing accidental or unauthorized use of nuclear weapons, preventing the possibility of a surprise attack, and so on. NR/ve A/C.l/ 40/PV. 5 26 (Mr. Petrovsky, USSR) The Soviet Union proposes that the entire body of practical measures aimed at preventing nuclear war should be given the most serious consideration. we call upon the United States and its allies to abandon their obstructionist policy in lliis matter, and reaffirm our position in favour of putting into practice the decisions of the General Assembly on the holding of business-like negotiations on lliis subject at the Conference on Disarmament. The Soviet Union is prepared not only to set in motion various mechanisms which could help to halt the build-up of nuclear arms and prevent their use, but also to solve the problem as a whole. We are in favour of starting without delay negotiations in the Conference on Disarmament aimed at working out a programme of nuclear disarmament. Appropriate methods and forms .of verification, satisfactory
