Strong motivation is the most important factor in getting you to the top.

Edmund Hillary (on scaling Mt Everest)

Some have compared the goal of a nuclear weapons free world to scaling an incredibly high mountain—and the mountain is covered in cloud making the peak invisible. Thus, they argue, all we can do is take small steps up the lower slope—hoping for better conditions in the future that might make it possible to climb higher.

The world has changed significantly since the founding of the United Nations and so have its conflicts. During the mid-twentieth century, the pre-eminent challenge for multilateral cooperation was the awesome prospect of a Third World War. Today, in the aftermath of the Cold War, we see a more elaborated focus on the prevention of conflict and the protection of communities and peoples—both as a sovereign responsibility of the modern nation-state as well as a central focus of the United Nations peace engagements.

Any organisation established in the aftermath of the Second World War obviously cannot fulfil its functions, in a world that has changed so dramatically, without adapting itself to the contemporary realities of international politics and economics.

When the United Nations Charter was promulgated on 26 June 1945, it reflected the immediate post-war situation and most importantly the international political balance of power that existed in 1945.

The title of this article is derived from a famous speech made by Jawaharlal Nehru, India's first prime minister, at the United Nations in December 1956. Over the previous decade, Nehru, together with his sister, Vijaya Lakshmi Pandit, and Mahatma Gandhi, had been working to build the UN into a form of global government. They termed their vision One World, and it had democracy and human rights as its basis.

To paraphrase the mantra of realism—international politics, like all politics, is a struggle for normative ascendancy: the establishment and maintenance of the dominant normative architecture of international order created and maintained by the interplay of power and ideas. As China, India and Brazil emerge as important growth centres in the world economy, the age of the West and its disrespect for the role, relevance and voice of the rest of the world is passing.
