Are the Iranian protestors alone?

It would be best for the world if the Iranian regime were toppled. It's hard to say where this will go but brutal measures to suppress the protests appear to have begun. Some inside Iran are asking, Is the world really aware of what's going on here? TWS blog posted an email from a Radio Farda's contact in Tehran:

I talked to a few students in Tehran (Monday morning Tehran time). They confirmed that the attack on their dormitory was brutal, destructive, and the authorities may have taken as many as 100 students with them. In Tehran, one faculty told me, the security forces had thrown some student off a building. There was an attack on a University dormitory in Isfahan as well. A similar episode happened in Shiraz a few nights ago. In last night’s attack, according to an ‘Amir Kabir Newsletter’ (I can send it to any journalist who can read Persian), security forces and others in civilian clothes were brutal: 5 students are reported in critical condition, and three were killed (including a female student). [...]

In my exchanges with them, I can’t help but be affected by their words. A question that I have heard several times is this simple one: Do the Americans know what is happening here? They don’t complaint, but they want to know if the silence is politics or indifference or… One said, I hope the diplomats in Europe don’t sell us cheap.

One comment made by a couple of them, and this is directed at people inside and outside Iran, is tough to take: ‘it seems that we are all alone.’ The Amir Kabir Newsletter says as much: as the security forces in civilian clothes attacked students in the dormitory, even as some of them were asleep, the university guards and authorities did not come to their defense and, as they faced these savages, students were left all alone.
