This has clearly become Khameini versus the people.  How this will turn out is anyone's guess.  Iran's history is full of crushed uprisings as well as successful mass overthrows of the ruling regime.  

I will say that if the govt. succeeds in crushing this rebellion it will be very violent and only temporariliy successful.  I expect there are many within the clerical, military and parlimantary establishment there who see this the same way.

There is definitely a way to move forward here and the whole thing seems balanced on a pivot at this moment.  On which side will weight come down?
