Currently we live in a world bristling with nuclear and conventional weapons—with a potential destructiveness unprecedented in history. A nuclear war, for example, would largely be over in one hour, with each second equivalent in destruction to World War II.

Meanwhile, our security is increasingly threatened by skyrocketing global military expenditure at the same time as the United Nation’s capacity to maintain peace is being undermined by member states starving the organization of funds.

The United Nations and its Prescription for a Better World

In the aftermath of two world wars, there was considerable hope that humanity would learn its lesson and that each would be “the war to end all wars.” Indeed, the United Nations was created for just this purpose, as stated in the Preamble to its Charter: “We the peoples of the United Nations determined to save succeeding generations from the scourge of war, which twice in our lifetime has brought untold sorrow to mankind…” But hope was not enough.

The Charter’s prescription for preventing violent conflict was a solid one. The states that joined the organization agreed, as an obligation of membership, to resolve their disputes peacefully and to refrain from the threat or use of force against one another.

The UN of today is staggering under the unparalleled expectation that it should be able to deal effectively with a multiplicity of extremely complex problems and that it should somehow be able to do so with resources that are woefully inadequate.

The prescription went beyond the peaceful settlement of disputes to address the root causes of conflict and create conditions for sustainable peace, pledging “to reaffirm our faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations large and small, and to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained, and to promote social progress and better standards of life in larger freedom…”

But before this hopeful blueprint could get off the drawing board, a new danger to global peace and security arose:

As the Charter was being negotiated and signed in San Francisco, the atomic bomb was being developed in Los Alamos, New Mexico, a thousand miles away… The first atomic bomb was exploded over Hiroshima on 6 August 1945, just forty-one days after the Charter was signed. By the time the United Nations was established on 24 October 1945, the world that it was to serve had changed in fundamental ways.

Indeed, for the next 45 years, the nuclear threat and the Cold War hung like a pall over the UN, greatly distorting the hopes invested in it by the world’s peoples.

When the Cold War suddenly ended, its legacy of abuse and neglect was not easily swept away. One superpower had bankrupted itself in the headlong race toward military superiority, and the other had spent vast resources developing expensive nuclear weapons.

Meanwhile, large segments of the world’s population lived in extreme poverty and were malnourished, unhealthy, and undereducated. The neglect of demographic and environmental problems led to a whole host of security threats, as underdevelopment, economic stagnation, and rising expectations generated conditions for protest, violence, and intrastate war. There were also new threats, as global warming; deforestation; desertification; degradation of air, soil and water; and loss of biodiversity endangered the health of the planet itself.

In the power vacuum following the Cold War, the UN was no longer sidelined but, instead, required to take center stage. In a short space of time, the expectations, demands, and responsibilities placed on the organization increased dramatically. An organization whose peacekeeping budget was no greater than the budgets of the New York City police and fire departments was asked to become the world’s police and fire department. At the same time, some who clamored for it to play this enhanced role continued to be late in payment of their dues or to withhold them altogether.

The UN of today is staggering under the unparalleled expectation that it should be able to deal effectively with a multiplicity of extremely complex problems and that it should somehow be able to do so with resources that are woefully inadequate.

Even so, over its 81 years, the UN has had many successes, exemplified by the 12 Nobel Peace Prizes awarded to various parts of the organization. Although detailing its work is well beyond the scope of this article, mentioning just a few achievements can provide some context.

At the time of the UN’s creation, almost one-third of the world’s population (750 million people) were under the yoke of colonial rule. Due to UN decolonization efforts, they are now citizens of 80 independent states and UN membership has grown from 51 to 193.

The UN operates at two levels. At the inter-governmental level, it offers venues (through the General Assembly and its committees, the Economic and Social Council and the Security Council) for member states to discuss international problems and take action, when possible. In a world dominated by Westphalian states, whose interests are not always aligned, multilateral decision-making is necessarily slow and cumbersome. But there are many instances where agreements have had far-reaching consequences. An example is the Universal Declaration of Human Rights and its covenants, as well as the many subsequent human rights instruments, including the establishment of mechanisms to monitor and assist their implementation.

Another example is the 2015 Sustainable Development goals and targets, including, “no poverty;” “zero hunger;” “good health and well-being;” “quality education;” “gender equality;” “clean water and sanitation;” “climate action;” “peace, justice, and strong institutions;” and nine others.

UN thematic conferences offer another opportunity for inter-governmental dialogue, with potentially constructive outcomes on issues such as climate change, HIV/AIDs, population and development, women and gender equality, racism, and others.

In a parallel process, the secretary-general, the Secretariat and its departments, as well as UN funds, programmes, and specialized agencies (i.e., the World Food Programme, the Office of the United Nations High Commissioner for Refugees, the United Nations Children’s Fund, the World Health Organization,........
