Here is a link for Hopi Prophecy, I believe it's taken from the book by Frank Waters. This particular prophecy doesn't mention the swastika being used for evil at the beginning of the end times, but it does mention a lot of other "signs" including:
"World War III will be started by those peoples who first revealed the light (the divine wisdom or intelligence) in the other old countries (India, China, Islamic Nations, Africa.)"
and it also says:
"The United States will be destroyed, land and people, by atomic bombs and radioactivity."
My only question is the mixing of known and unknown technology as it applies to the time these prophecies were given, there seems to be a mix of old and new prophecy.
At any rate, "We report, You decide"........
