UN General Assembly
1966

We seem to be as far as ever from reaching that goal; but it must also be recognized that certain intermediate steps must necessarily be taken. It is in this respect that General Assembly resolution 2028 (XX) must be regarded as a substantial step forward, inasmuch as it has defined non-proliferation as a means toward an end, and as it has just as clearly defined the respective balance of responsibilities and obligations of both nuclear and non-nuclear Powers. 13.
