No one is born a good citizen or a good democrat or a good leader; it takes time and education.

You will recall that for months after 9/11, there was incredible support and sympathy for the US. I really hoped and wished they had played on that, and kept all these friends they had made, and found a way of dealing with the terrorists through co-operation of international intelligence services, police exchange of information.

There is no tool for development more effective than the education of girls and the empowerment of women... When women are fully involved, the benefits can be seen immediately: families are healthier; they are better fed; their income, savings, and reinvestment go up. And what is true of families is true of communities and, eventually, whole countries.

The young and dynamic and idealistic people in the square do not have the chance to organise themselves politically, to be able to follow through their dreams in six months time, to play an effective role in the future.

It's not that easy to quit. When you look back in the American system it is very rare that people quit on issues of principle.

We need to promote greater tolerance and understanding among the peoples of the world. Nothing can be more dangerous to our efforts to build peace and development than a world divided along religious, ethnic or cultural lines. In each nation, and among all nations, we must work to promote unity based on our shared humanity.

On this International Day of UN Peacekeepers, let us pay tribute to the men and women from countries across the world who serve selflessly, tirelessly and fearlessly in UN peacekeeping operations. Let us remember the heroes who have laid down their lives in lands far from their own in the service of peace. And let us reaffirm our commitment to building a world free from the scourge of war.
