Sorry to say, but I lost my faith in this corrupt organization that serves the political will of a few super powers and does little to keep the peace, stop Russian and American invasions, and has no way to punish any member of the Veto-holding members. They consume a lot of money and are seldom objective as delegates (ambassadors) trade their votes for favors and money. http://www.defenddemocracy.org/united-nations-corruption-and-the-need-for-reform/
Like the IMF, WTO, and World Bank, the UN has become just another organization that serves the elite who have their own agendas. Yeah they operate UNICEF and a few good agencies, but overall it is a political machine that favors western and specifically American foreign policies. http://www.economist.com/node/4267109
