The Navajo Nation pressured Congress for the Congressional Medals to be given their Marine Code Talkers. This was, in effect, their deliberate 'up yours' to the Army's Code Talkers of many tribes and nations who served honorably, bravely, and effectively in Europe and the Mediterranean And I seem to recall that there were also Code Talkers in the Navy.

What would it have hurt the Navajo to say, "Let our country honor ALL Code Talkers."?

(Rhetorical question, it was in-your-face greed)
