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.

The American war of 1861-65 is recent enough to be embedded still in cultural memory.

I know who Queen Elizabeth represents. I know she's the head of the British state. I know she has all sorts of titles in relation to different regiments in the British army. She knows my history. She knows I was a member of the IRA. She knows I was in conflict with her soldiers, yet both of us were prepared to rise above all of that.

It's to be a person who's able to shoot little arrows into sacred cows and knock politicians off their pedestals, to look out for hypocrisy, advocate for all sorts of things from social justice to peace.

Growing up during the Cold War, I remember the seemingly imminent threat of nuclear war. In primary school we were taught to 'duck-and-cover' for protection. But even as children hiding under wooden desks, we recognized the inadequacies of this strategy.
