The United States will be destroyed, land and people, by atomic bombs and radioactivity. Only the Hopis and their homeland will be preserved as an oasis to which refugees will flee.
Bomb shelters are a fallacy. "It is only materialistic people who seek to make shelters. Those who are at peace in their hearts already are in the great shelter of life. There is no shelter for evil.
Those who take no part in the making of world division by ideology are ready to resume life in another world, be they Black, White, Red, or Yellow race. They are all one, brothers."
Hopi prophecy states that World War III will be started by the people who first received the Light: China, Russia, Palestine, India and Africa. When the war comes, the United States will be destroyed by "gourds of ashes" which will fall to the ground, boiling the rivers and burning the earth, where no grass will grow for many years, and causing a disease that no medicine can cure.
This can only mean nuclear or atomic bombs; no other weapon causes such effects. Bomb shelters will be useless, for "Those who are at peace in their hearts already are in the Great Shelter of Life.
There is no shelter for evil. When the Saquahuh (blue Star) Kachina dances in the plaza and removes his mask, the time of the great trial will be here." The Hopi believe that only they will be saved.
