The American Revolution, and others like it (China), succeeded because there was a long-term organized committment to planned success. Some revolts succeed because the powers that be do succumb to the onslaught (Romania, France), but those required a direct, er, hands-on approach. Iran is just about lots of yelling; people get tired of yelling, and those being yelled at come to ignore it.
This is still impossible to predict. The citizens are not armed, or it would not be like this.
All it would take for this to go-off is for 1 Military commander to defect. It would then be on.
Or outside arms smuggled in, would bring on a gorilla war that could escilate.
The election was clearly a fraud, and everyone knows it.
Islamic governments like Communism can only exist with repression. Nature of the beast.
Freedom is incompatible with dictatorial government.
If we manage to get obama out of the white house and Palin in,we need to have something like the OSS of WWII to help give support to pro democracy/anti islamic movements worldwide
