Khamenei's Nephew: Supreme Leader "Toy"

Mahmud Tehrani is the son of Khamenei's dissident brother-in-law Sheikh Ali Tehrani. He has some harsh words:

I think Khamenei -- who is my uncle -- is either a toy in the hands of Ahmadinejad, [Ayatollah Mesbah Yazdi], and the Revolutionary Guard, or he shares their crimes.

There is nothing he can do. If he backs off from his comments even one step, he will lose his leadership and the whole [conservative] camp will disintegrate.

I don't think Ali Khamenei has a lot of power, it's likely that all of this is being run by the Revolutionary Guard, and Ali Khamenei is forced to deal with the [Revolutionary Guard] in order not to lose his role as the supreme leader. He can't do anything and he won't say anything [substantial]. Since June 14 we haven't heard anything from Khamenei other than repeating Ahmadinejad's comments.
