More than ever before in human history, we share a common destiny. We can master it only if we face it together. And that, my friends, is why we have the United Nations.

Children are our future and if we use them in battle, we are destroying the future. We must reclaim them, every one of them, one at a time.

On this International Day of Peace, let us all honor those who have suffered from violence. Let us hold in our hearts the ideal of peace.

We at the U.N. have to take some of the blame, because we have not lowered expectations creating the impression we are here to save people, even when we have very limited resources.

HIV/AIDS has become much more than a health issue. HIV/AIDS is a development issue, it's a security issue.

As we move forward, you cannot resolve the potential food crisis or shortages without science being part of the solution. Science has to be part of the solution but African governments - and these are decisions for governments, whether they embrace or do not embrace genetically modified food - and for the moment, most African companies do not accept genetically modified seeds.

One has to have the strength of character to say the time has come to move on... unless you are a king.
