Friday-morning quarterbacking Iran

Juan Cole's assessment is pessimistic, but worth reading in full.

• What I would say is that coming off the Ashura protests, the Green Movement had the momentum and the regime was under pressure. The rallies had spread to a number of cities, including conservative ones like Isfahan and Mashhad. The crowds seemed to be turning on Supreme Leader Ali Khamenei.
• After Thursday, the momentum is now with the regime. Either the Revolutionary Guards are getting better at countering the dissidents or movement members are tired of getting beaten up with no measurable political impact. As I said yesterday, the regime blocked the 'flashmobs' by interfering with electronic communication (google mail, Facebook, Twitter). They also thought strategically about how to control the public space of major cities, resorting to plainclothesmen rather than just uniformed police squads....
• The Green Movement cannot depend on being able to go on indefinitely mounting big public demonstrations, especially since the cost to the protesters is rising, with beatings, firing of live ammunition, mass arrests and executions. It also cannot continue to depend on informal networks to organize, since these can be fairly easily disrupted.
• Mir Hosain Musavi has said he refuses to form a political party. There are such parties or at least vague groupings in Iranian politics (former president Akbar Hashemi Rafsanjani leads one), and they have members of parliament. By refusing to develop a grassroots political organization, Musavi may be making the same mistake as former president Abo'l-Hasan Bani-Sadr, who was toppled from the presidency in summer, 1981, because he declined to seek a mass organization, whereas his enemies had the "Hezbollah" popular militia and the Islamic Republican Party that grouped key hard line clerics. Ahmadinejad has his Alliance of Builders in Tehran, and is backed by the Revolutionary Guards, the Basij paramilitary, and other security forces. Musavi has the little flashmobs who couldn't, at least on Thursday. (Informed Comment, "How the Iranian Regime Checkmated the Green Dissidents on a Crucial Day," 12 Feb. 2010)
  

Also, I think we cannot discount the overwhelming force on that day.
