The fight against HIV/AIDS requires leadership from all parts of government - and it needs to go right to the top. AIDS is far more than a health crisis. It is a threat to development itself.

The war on drugs has failed in West Africa and around the world

When the US withdrew their troops from Somalia, I recall making a comment that [in] the way the peacekeepers had been withdrawn from Somalia, the impression had been given that the easiest way to unravel a peacekeeping operation is to kill a few soldiers.

The global HIV/AIDS epidemic is an unprecedented crisis that requires an unprecedented response. In particular it requires solidarity - between the healthy and the sick, between rich and poor, and above all, between richer and poorer nations. We have 30 million orphans already. How many more do we have to get, to wake up?

In all these cases, part of the reasons for failure perhaps was not analyzing and assessing the true nature of the crisis, the resources that would be required, and exaggerated expectation of what the U.N. troops can do.

The other thing that really I regretted not being able to do was to push effectively for the reform of the Security Council. Because the world was changing, and is changing very fast, and I felt the UN was holding on to old arrangements. Most governments felt that it has such a narrow power base, based on the results of the second world war.

Access to safe water is a fundamental human need and therefore a basic human right.
