Here is a question for someone who knows alot about the United Nations?

The United Nations promotes collective security. The UN doesn't exist because it has power to force its will on the world's states, however it exist because states have to it serve their needs. It only has as much power as given by the states that are involved in it. The United Nations can not invalid a state's sovereignty.

UN's power is not of the typical kind. It does not have much military might, and due to the charter giving the 5 permanent countries on the Security Council veto power not much gets done- due to opposing interests by US, China, Russia, France, UK. As a result, the main function of the council is to promote a forum for countries to air their grievances. It also forces countries to respond to their actions. The International Court it runs barely does anything- around 5 cases a year I think- and attendence is optional. The cases usually deal with fishing disputes on international boundaries in the oceans. The UN helps with refugee situations with some regularity, by sending peace keeping troops to help thousands of displaced people form a camp and stabalize. Just check out the UN's website for more details on what they have accomplished, but their greatest contribution is giving all countries a voice to be heard by all the other countries- all though too often it falls upon deaf ears.
