Obama saying Gaddafi must go. Putting it upfront like that... it's not very helpful.

Most governments only want to deploy a peacekeeping force where there is a peace agreement and there is peace to keep. They are very hesitant about putting their men and women in harm's way. It is extremely difficult to get the troops if you do not have the consent of the country where you are deploying.

Nelson Mandela stands as an inspiration to us all

The UN doesn't work in a vacuum.

Human beings are not property. On the International Day for the Abolition of Slavery, let us reaffirm the inherent dignity of all men, women and children. And let us redouble our efforts so that the words of the Universal Declaration of Human Rights - 'no one shall be held in slavery or servitude' - ring true.

One of my biggest regrets was the fact that as an institution and an international community we could not stop the war in Iraq. That really was very difficult and very painful. Every fibre in my body felt it was wrong. I spoke to leaders, we spoke to people, we tried... we couldn't stop it... and we see the results.

... the long-lasting humanitarian impact of these inhuman weapons continues to deny communities the opportunity to rebuild long after the end of the conflicts.
