"The Green Movement Is Radicalizing."
Only in part. It's important to remember that Iran's green movement began well before protests broke out in June 2009. The origins were in the mowj-e-sabz, also known as the "green wave," a campaign to support the presidential bid of reformist candidate Mir Hossein Mousavi, who ran against conservative incumbent Mahmoud Ahmadinejad.
The green wave's goals were to wrest the presidency and executive power away from radical hard-liners whose term in office had been marked by economic incompetence, foreign-policy adventurism, and an ideological doctrine that included new limits on civil rights and that Mousavi's supporters believed was unsuited to Iranian interests in the 21st century.
After the disputed election results, the green movement morphed from a political campaign into a campaign to annul the presidential election -- and then, more broadly, into a movement to restore the civil liberties promised by the 1979 Islamic Revolution. With every instance of recent government tyranny, from show trials of opposition politicians and journalists to the beatings and murders of some demonstrators on Iran's streets, the movement has grown more steadfast in its demands for the rights of the people.
Over time, and particularly with the government's continued use of brutal force against its citizens, some Iranians are no longer satisfied with the stated goals of the green movement, but are looking to topple the Islamic regime altogether. For instance, we hear in the Western media many instances of Iranians clamoring for an "Iranian," rather than Islamic, republic (a call that Mousavi has disavowed) or for "death to the supreme leader." Meanwhile we see on YouTube and our TVs footage of Iranians violently confronting security forces.
However, the radical elements claiming to be a part of the green movement only speak for a small minority of Iranians. The majority still want peaceful reform of the system and not necessarily a wholesale revolution, bloody or otherwise. That's why, in the most recent Ashura demonstrations, for example, large groups of peaceful marchers actually prevented some of the movement's radicalized elements from beating or attacking security forces. Although accurate polling information is not available, based on what we hear and see of the leaders of the green movement and many of its supporters, radicalization is still limited to a minority of protesters.
The green movement's leaders recognize that any radicalization on their part will only bring down the state's iron fist. They are also cautious because they know that if movement leaders call for regime change rather than reform and adherence to the Constitution, they will only have proven the government's assertion that the movement's goal all along has been to topple the system.
