23. The United Nations

The United Nations (U.N.) is an international organization whose stated aims are to facilitate co-operation in international law, international security, economic development, social progress and human rights issues. It was founded in 1945 at the signing of the United Nations Charter by 50 countries, replacing the League of Nations, founded in 1919.

The UN was founded after the end of World War II by the victorious Allied Powers in the hope that it would act to intervene in conflicts between nations and thereby avoid war. The organization's structure still reflects in some ways the circumstances of its founding. The five permanent members of the U.N. Security Council, each of which has veto power on any UN resolution, are the main victors of World War II or their successor states: People's Republic of China (which replaced the Republic of China), the French Republic, the Russian Federation (which replaced the Union of Soviet Socialist Republics), the United Kingdom, and the United States of America.

As of 2007, there are 192 United Nations member states, encompassing almost every recognized independent state. From its headquarters in New York City, the UN and its specialized agencies decide on substantive and administrative issues in regular meetings held throughout each year. The organization is divided into administrative bodies, including the General Assembly, Security Council, Economic and Social Council, Secretariat, Trusteeship Council, and the International Court of Justice (ICJ). Additional bodies deal with the governance of all other UN System agencies, such as the World Health Organization (WHO) and United Nations Children's Fund (UNICEF). The UN's most visible public figure is the Secretary-General. The current Secretary-General is Ban Ki-moon of South Korea, who assumed the post on 1 January 2007.

The United Nations was founded as a successor to the League of Nations, which was widely considered to have been ineffective in its role as an international governing body, in that it had been unable to prevent World War II. Some argue that the UN's major advantage over the League of Nations is its ability to maintain and deploy its member nations' armed forces as peace keepers. Others see such "peace keeping" as a euphemism for war and domination of weak and poor countries by the wealthy and powerful nations of the world.^[2] Initially, the body was known as the United Nations Organization, or UNO. However, by the 1950s, English speakers were referring to it as the United Nations, or the UN.

The street address of the UN headquarters is: 760 United Nations Plaza, New York City, NY 10017, USA. Due to security concerns, all mail sent to that address is sterilized.

The UN buildings are not considered separate political jurisdictions, but do have certain aspects of sovereignty. For example, under agreements with their host countries the United Nations Postal Administration is allowed to issue postage stamps for local mailing. Since 1951 the New York office, since 1969 the Geneva office, and since 1979 the Vienna office have had their own issues. UN organizations also use their own telecommunications ITU prefix, 4U, and unofficially the New York, Geneva, and Vienna sites are considered separate entities for amateur radio purposes. As the UN main building is aging, the UN is in the process of negotiating to build a temporary headquarters designed by Fumihiko Maki on First Avenue between 41st and 42nd Streets for use while the current building is being expanded.
