Blessed are the Peacemakers

It's Memorial Day Weekend. Why is it we always memorialize warriors, but not those who work for peace? So today let's celebrate those who work for people and planet. I thought it might be fun for everyone to add agents of peace they have encountered in the comments. As we begin it is important to consider that perfection is not a human condition. However some people are drawn into the service of peace because they see the insanity of war. Smedley Butler comes to mind...both a soldier and a peacemaker.
