The problem with Reza is that he does not have strong leadership qualities like his father did.
Nor his grandfather and namesake - but we play the hand given to us - and he is the only decent card available, who has any kind of standing within the Iranian populace. And can build an AntiMullah following inside the country, which would be acceptable to the civilized world.
There are of course the Mojaheddin (MEK) but they are a Marxist flavor of the Mullahs and would allow music and movies etc., but also impose social and political restrictions and while eradicating the clerics, would also eradicate many freedoms we used to have under the Monarchy.
It is up to the rest of us to help out as best we can. Not for reward or high positions but because it needs doing.
