The Navajo Code Talkers faced a serious moral dilemma when deciding to help the United States military during World War II.
The dilemma was whether or not the code talkers should help the US government despite the poor treatment Native American tribes have faced over the course of the last century.
During the 1800's, the federal government and military treated Native American tribes horribly. This included forcing them to move off their homelands and onto reservations, going to Indian Boarding schools, etc. Despite all the poor treatment received by the Native American tribes, they still decided to help the US during World War II.
