Well I didn’t say it was likely to happen just that that was what the Ghost Dancers believed back in the day. I have no idea if any Indians take stock in that now. I kind of doubt it. It’s more likely that believers in the power of the White Buffalo today see it more as a spiritual awakening and purification than a temporal salvation of the land and their old way of life.
As I understand it the Ghost Dance was supposed to lead to racial unity, but it became a war dance.
