Without losing all hope in the UN, which is understood as a mere meeting place or a forum most of the time, one must acknowledge the challenges and inner contradictions it faces. Economy seems to be more and more of a problematic issue for the United Nations, who are losing their leading role to specialized institutions (the WMF, the WTO…) and are failing to implement their founding doctrines. The defence of human rights is challenged by a blatant lack of binding means. The UN is also painstakingly making its way between apparently contradictory principles: the sovereign equality of States, the right of people to dispose of themselves and the right of interference. Finally, one can also notice hardships in peace and international security.
