I believe that our world needs an instrument of global action as never before in history. I believe that the United Nations is the instrument for securing peace and for giving people everywhere, in poorer countries as in richer, a real stake in that peace by promoting development and encouraging cooperation. But the United Nations is only an instrument, an actor in need of props and cues from its directors, And so I will paraphrase Winston Churchill: Give us the tools-the trust, the authority and the means-and we will do the job.

The [UN Security Council] P5 ought to be dissuaded from using their veto power, which can paralyze the United Nations.
