This memorandum for Cabinet succinctly summarizes Aiken’s approach after 1961. He supported the negotiations of the Eighteen Nation Disarmament Committee (ENDC) but recognized and held to the position that Resolution 1665 (XIV) provided the basic roadmap for an eventual agreement of a global non-proliferation treaty. More specifically, he maintained that 1665 provided the basis by which NATO nuclear sharing could be accommodated. Aiken was skeptical of Soviet contentions that a non-proliferation pact would prevent the proposed Multilateral Force (MLF). The Irish position was that it would not engage in the detailed ENDC discussions as it was for that body and the nuclear powers to broker the detailed provisions for an NPT owing to their knowledge of, and interests in, nuclear energy.
