In countries where democracy is either non-existent or in development, on the other hand, citizens crave those freedoms. Maybe that is one lesson Western citizens can learn from those countries: treasure what you have. Use your rights and freedoms to effect the change you want.

My own advice to people who would be in office for two or three terms is that they must accept democratic rotation. Ideally not put themselves up for re-election and allow the system to work.

The United Nations, whose membership comprises almost all the States in the world, is founded on the principle of the equal worth of every human being.

If we can come up with innovations and train young people to take on new jobs, and if we can switch to clean energy, I think we have the capacity to build this world not dependent on fossil-fuel. I think it will happen, and it won't destroy economy.

Often, we take stability - peace in terms of security and economic activity - to mean a country is doing well. We forget the third and important pillar of rule of law and respect for human rights, because no country can long remain prosperous without that third pillar.

Sadly, a prize for peace is a rarity in this world. Most nations have monuments or memorials to war, bronze salutations to heroic battles, archways of triumph. But peace has no parade, no pantheon of victory.

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.
