In an age of interdependence, global citizenship - based on trust and sense of shared responsibility - is a crucial pillar of progress. At a time when more than one billion people are denied the very minimum requirements of human dignity, business cannot afford to be seen as the problem. Rather, it must work with governments and all other actors in society to mobilize global science, technology and knowledge to tackle the interlocking crises of hunger, disease, environmental degradation and conflict that are holding back the developing world.

To go to war without the Security Council will not be in conformity with the Council.

Nuclear terrorism is still often treated as science fiction. I wish it were. But unfortunately we live in a world of excess hazardous materials and abundant technological know-how, in which some terrorists clearly state their intention to inflict catastrophic casualties. Were such an attack to occur, it would not only cause widespread death and destruction, but would stagger the world economy... [creating] a second death toll throughout the developing world.

Sometimes I walk into a situation and I know somebody is going to provoke me - not maybe, I know he will provoke me - I know he will provoke me! And there are times when I simply refuse to be provoked. And the other times you have to use that superior knowledge to carry on at work without distraction, and don't allow yourself to be distracted.

Sometimes when you take a tough action against one side in the conflict, they see you as part of the conflict and they attack you.

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 question is the morning after. What sort of Iraq do we wake up to after the bombing? What happens in the region? What impact could it have? These are questions leaders I have spoken to have posed.
