Many of the wars we see around the world start as domestic conflicts that are fueled by external forces and powers. My view is that we can help peace if we help communities transform from the inside, on their own terms.

For many child soldiers, war and violence are all they have ever known. If we don't take it upon ourselves to show them an alternative, then they're going to be soldiers forever, and they'll continue to be recruited and to participate in violence if another conflict starts five or 10 years down the road.

I've been trying to understand conflict and violence ever since I was a kid. You know. There were a few things that happened even on my block - the Black Panthers used to be right around the corner from where we were.

While it's easy for South Sudan to feel distant, the situation is all too real for the South Sudanese mothers choosing which child gets to eat tomorrow. This is a time when we must look outward together and declare that humanity has no borders - no one deserves to suffer like this, especially in a world of such abundance.

But Americans do make the connection between their fears about their own jobs and their broad understanding of the A.I.G. debacle.

The Berlin Wall wasn't the only barrier to fall after the collapse of the Soviet Union and the end of the Cold War. Traditional barriers to the flow of money, trade, people and ideas also fell.

Paris is a danger for people like me. We spend our rent money in Paris on clothes.
