It was a broader claim about the intrinsic value of the language and the culture it carried.

But the Code Talker story gave that broader claim a specific, concrete, historically documented anchor that was difficult for skeptics to dismiss.

The American Indian Movement and other Native activist organizations of the 1970s made the boarding school era’s assault on Native languages a central part of their critique of federal Indian policy.

The Code Talker story, to the extent it became public in this period, was consistent with that critique and provided evidence that the policy had been not merely harmful but also strategically irrational from the federal government’s own perspective.

This intersection between the Code Talker story and the broader language revitalization movement of the late twentieth century is an aspect of the program’s legacy that popular accounts rarely explore but that has been genuinely significant.

The program’s declassification in 1968 coincided roughly with the beginning of a period of intensified Native advocacy that would produce the Indian Self-Determination Act of 1975, the American Indian Religious Freedom Act of 1978, and a series of other legislative and policy changes that began to reverse the assimilationist thrust of earlier federal Indian policy.
