PROBLEM: (CNN) When Peter MacDonald, Fleming Begaye and Thomas Begay joined the elite fraternity of Navajo Code Talkers during World War II, they had no idea what they were getting into. That was by design. The top-secret program they joined wouldn't even be declassified until more than two decades later -- long after the secret Navajo code language had played a vital role in the American war effort. All they knew at the time was that the Marines were recruiting and needed help from the Navajo people. "So we all volunteered. That's how he went in, that's how he went in, that's how I went in," said MacDonald, now 90, of his two comrades.
