i been hearing about the imminent People’s revolution in iran since i was in high school.. 1990ish... i’m with the other guy... they’re never going to do it.
However, all 'revolutions' that are not based on a realistic understanding of human nature all fail in time, with the fall of the Soviet Union being a prime example.
Still, the colorful revolutions in the Iron Curtain countries were aided and abetted by the United States and Pope John Paul II. Just as our Revolution in the 1700's would have failed without the support of France, so it is that an outside agency is often necessary to support internal revolutions if they are going to be successful.
Of course, the same was said about the many countries under the Soviet heel, including the Soviet Union themselves...and was said for a much longer time.
I would never say never...
