It is not in the United Nations that the Millennium Development Goals will be achieved. They have to be achieved in each of its Member States, by the joint efforts of their governments and people.

I have always believed that on important issues, the leaders must lead. Where the leaders fail to lead, and people are really concerned about it, the people will take the lead and make the leaders follow.

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.

The past year's natural disasters have highlighted the invaluable contributions of volunteers in our communities. They have volunteered their time, energy and skills to save lives and to rebuild communities. In this they joined countless people around the world who volunteer every day in response to 'silent crises'. These often unsung heroes understand all too well that poverty, disease and famine are just as deadly and destructive as earthquakes, hurricanes and tsunamis.

I've been around enough to realise that there are two things that once people have them, they don't want to give up, and it's extremely difficult to convince them to give up: one is privileges, and the other is subsidies.

Some have suggested that ideally there must be some international body that would treat areas like the Arctic as a global commerce, a bit like the way we treat the sea. It doesn't belong to any particular country, but to all of us, but I'm not sure some of the powerful are ready for that sort of solution.

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.
