There is a good analysis of the situation in the higher levels of the administration in Iran at www.asharq-e.com. It is provided by Ebrahim Yazdi who, although he is the sometimes persecuted head of a banned political party, has a fairly cool perspective.

My bet is that Ayatollah Khamanei will resign his position this summer ‘for health reasons.’ But since I was wrong about the demonstrations ending by now … Insh’allah.
