Learn about peace by looking at history. Read about the wars that have scarred our souls in modern times, like the World Wars, Korea, Vietnam, Iraq, Ireland, Afghanistan, Bosnia. Make a list of the causes of each, both the official and actual ones. Of course, in all cases the causes boil down to one thing: denying the fact that we are all part of the human family. However, note recurring themes–an ethnic group believing in their own superiority, people fighting for a certain piece of land, one group intent on keeping specific natural resources for themselves, yet another…. Well, you’ll see when you make your list. Once you have this list, watch the news with an informed eye. When you see one of these causes poking its head out of the swamp of international politics, pray hard and write your lawmakers, insisting that they take action before it’s too late.
