This is Chester Nez. Chester is 92. He is a United States Marine. He is a veteran of World War II. These are all amazing things. But there's more. Chester is also the last of the original Navajo Code Talkers. He and 28 other young Navajo men developed the only unbroken verbal code in modern warfare. Based on the language of their people, that code in no small way shifted the tide of the war in the Pacific theatre. Chester changed the world. And yesterday afternoon, he smiled when I asked to take his photograph. I am deeply honored.
