In the face of violence that seems intractable and suffering that is so senseless, it is easy to grow cynical, and I think tempting to give in to the notion that peace and security may be beyond our grasp. But I say to all of you here today, especially the young people, do not give into that cynicism. Do not lose the idealism and optimism that is the root of all great change. Don't ever lose the faith that says, if we want it, if we are willing to work for it, if we stand together, the future can be different; tomorrow can be better.
