I think to address this question, we much first identify some key concepts, and the institutions which are fundamental to the United Nations. This will then allow me to analyse whether or not in my view the United Nations is in fact at risk of becoming obsolete. The UN is the result of an extended history of efforts to try and promote international cooperation. During the late 18th Century, the German philosopher Immanuel Kant proposed a league of the world's nations.

of the less developed countries. Only then would the United Nations truly be considered as the successful international institution.

So to conclude, I do not think the UN is at risk of becoming marginal or irrelevant, from my research I think it is clear that they have a large international standing, and work for a greater good. I think if anything that the UN can be said to extremely successful in achieving its goals, but like many international organisations set their goals based on a utopia ideology and subsequently can never be completely successful in their goals.
