Wikipedia: United Nations
The United Nations (UN) is an intergovernmental organization to promote international co-operation and to create and maintain international order. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the UN is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict. The UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organisation in the world.

The UN is a country club, especially for some of those non-important nations that are so tiny, they can fanticize they have more power than they do…..  Nothing really important happens in the UN…  Never has.
