Thanks to a crude bomb that just exploded in a dumpster in New York, much of the world learned that the United Nations General Assembly is preparing to convene in New York, as it does it does every year at this time. What much of the world does not know is that at the same time the U.N. sponsors an annual International Day of Peace “devoted to strengthening the ideals of peace, both within and among all nations and peoples.”

Given that I write a blog about world peace, I’m a big fan of this day. This year, I will celebrate it in another country. I’m also a big fan of travel. I believe that war is often (though not always) the result of old grievances and common fears being nurtured and ignited by politicians eager to preserve power and prestige for themselves and wealth for their friends. I recognize that any interaction that results in armed conflict is complicated, and that many people try to do what is best. However, my own reading of history tells me that “bloody few” armed conflicts were ever noble or unavoidable; the only thing they all have in common is that they were bloody.

Those of us not in politics have few ways to steer the human race away from the machinery of war. One of those is travel. As we spend time with others who are currently demonized, or who once were, we learn to question the assumptions about other nations, religions, races, continents, and what ever else you have when you describe “those people” in terms vile enough to make the average citizen believe that they must die. Of course, you can’t just get on a bus or plane and go somewhere. You need to interact.

You need to try to drive up a road that your GPS should never have thought was a road in the first place. You need to try to turn around on a steep, narrow hairpin curve and manage to get your rental car stuck with its nose in the dirt and its ass two feet off the ground while your tires spin. You need to hike down the hill, stand out on a highway, and hope that some decent people will stop and give you a hand.

Odds are they will. If you are lucky, someone like Alberto and Maria will pull over cautiously, looking nervously at their daughter in the back seat. They will see how sweaty and frustrated you are, and ask what is wrong in a language of which you speak only a hundred words quite poorly. You will figure out that they speak no English, but you might manage to convey carro for car and espouso for husband and point up the hill. If you are very lucky Alberto will say “cima?” very clearly, like he cannot believe both the car and husband are up there, and you will recognize his word for “on top of” from your hours with Rosetta Stone and you will nod.

On a good day, Alberto and Maria will take it from there. They will drive their old car up the road that brought you to a standstill, chuckle with sympathy when they see your predicament, and gesture to the two of you to help them lift your car and literally set its rear end down in a better place. While you marvel that it is even possible, it is done. You will try to press some money into their hands, helpless to thank them any other way, and they will not want it, at least not until you insist. Maria will give you a hug and, as she does, you and she will both have tears in your eyes, brought on by the intensity of the exchange you have managed without a single word. They will drive off and you will never see them again.

But later that night, as you read about the ideals of learning to coexist with your fellow humans, you will think of them, and understand how one can travel for world peace.

So, Happy International Day of Peace, Alberto and Maria. May others always treat you with the same kindness that you showed to us. And happy Peace Day, as well, to your seven billion brothers and sisters, most of whom have needed help at least once or twice and, in turn, have helped a stranger or two along their way.
