evidence: The United Nations (UN) is a diplomatic and political[2] international organization with the intended purpose of maintaining international peace and security, developing friendly relations among nations, achieving international cooperation, and serving as a center for coordinating the actions of member nations.[3] It is widely recognised as the world's largest international organization.[4] The UN is headquartered in New York City, in international territory with certain privileges extraterritorial to the United States, and the UN has other offices in Geneva, Nairobi, Vienna, and The Hague, where the International Court of Justice is headquartered at the Peace Palace. [...] The new international organisation was formulated and negotiated amongst the delegations from the Allied Big Four at the Dumbarton Oaks Conference from 21 September to 7 October 1944. They agreed on proposals for the aims, structure and functioning of the new organization.[28][29][30] It took the conference at Yalta in February 1945, and further negotiations with the Soviet Union, before all the issues were resolved.[31] [...] - Coulon, Jocelyn (1998).
