The lack of education of the leaders of the United Nations is a blatant yet unspoken truth. In order to formulate any opinion about the world, let alone a fact, one must have a firm grasp of history, of world history, of how the modern world works, of how civilization is formed, sustained, and survives in various ways depending on political climate and human nature, and how this impacts others.
Why is the world falling apart?
It is the failure of placing educated leaders in the one place it matters most, the nexus of countries and continents, the United Nations, a place where negotiation must be mastered and perfected, where precedents are known, various forms of law understood, and solutions known by educated intuition and reasoning.
Why has the United Nations failed to fulfill its purpose on multiple world conflicts?
It is precisely that they do not know what the world is, how it functions, and how to fix it.
In one sense, world war is the easiest thing to deter, as the end result is an absurdity, war between all nations. However, it is difficult to make this known, for many countries, falsely believe that they may get something out of it, when in reality the cost is too great to bear, even the loss of the support and resources of one country globally is a cost too great.
