Aiken made an immediate impression on his arrival in the Twelfth Session of the UN General Assembly in September 1957. He adopted an impartial posture of assessing each issue on its merits and campaigning to remodel international politics around self-determination, humanitarianism, and peace. His exhortation was that only the UN had the moral authority and political legitimacy to put forward global solutions. While he did not propose nuclear disarmament measures specifically, his intent was signaled by his recommendation for a mutual drawback of foreign forces (including their nuclear weapons) in central Europe and his endorsement of a proposal to discuss the representation of China in the United Nations. The Eisenhower administration was hostile to Aiken’s course as outlined in the U.S. ambassador’s audience with Taoiseach Eamon de Valera and Aiken in Dublin on 2 October.
