Abstract

The United Nations is the world's most extensive international organization whose primary task is to create a new international security framework, the maintenance of international peace and security. United Nations not only to retain the World Health Organization, International Labour Organization, International Court of Justice and other international cooperation organizations, to promote throughout the world from Euro-centric changes to the global system, but also provides a world political center stage, but it has not succeeded in expectations of its founders to establish the international security framework and the security of each country to obtain a new world order. The end of the Cold War can finally restore the UN's ability to successfully perform the duties assigned to it by the Charter, or whether the disappearance of confrontation between the superpowers but exposed the establishment of a global structure of international security barrier deep, although it seems after the were more likely, but will wait and see. The United Nations is the most general international organization in the world at present, the primary mission of which is to establish a new international security framework in order to maintain international peace and security. The UN not only preserved international cooperation organs like the World Health Organization , the International Labour Organization, and the International Court of Justice, and facilitated the transformation of the world from a Eurocentric to a global system; but also provided a focus for world politics. But it has not succeeded in creating an international security framework conceived by its fathers and a new world order from which every state gains a security shield. It remains to be seen whether the end of the Cold War will eventually restore the capacity of the UN to fulfil the role set in its Charter; or whether, as scents more likely, the disappearance of superpower confrontation will only reveal deeper systematic obstacles of the creation of an effective global structure of international security
