Why are the Navajo people important to the war in the pacific?

The native Americans were viewed by many as unimportant savages throughout the early united states. today, many laws are in place so that those of native-American descent will (hopefully) become somewhat prosperous. it's America trying to repay at least a small amount of the suffering that the early U.S. caused. native Americans today are probably one of the worst-off minority groups. quite sad, considering they were here long before we were, and attempted to become more American by creating schools, and even writing their own languages.
