Aiken drafted in additional personnel to the Irish Mission to the UN in the run-in to the XVIth UN Session. Seán Ronan, the head of the political and information divisions at headquarters in Dublin, was sent as a delegate to the First Committee of the UN, involving him intensely in Aiken’s non-dissemination efforts. His insider account reveals some of the dynamics and calculations at play in the building, as Ireland managed a balancing act of engineering consensus between East and West. In large part, the Irish Mission crafted the resolution’s language to skirt the issue of alliance nuclear sharing in a bid to manufacture unanimity. The Irish had pondered co-sponsoring a Swedish draft resolution but anticipated that it would face resistance from NATO comparable to earlier iterations of the Irish resolution. Similarly, Ireland neglected to mention a proposed new disarmament committee in the draft resolution – there was no guarantee that it would form and report expeditiously. Finally, by drawing on the instrument of acclamation, the Irish sidestepped French objections and gained universal approval for Resolution 1665 (1961), wrapping the resolution in universal legitimacy.
